The year 2020 has seen so much adversity but we must stay optimistic by finding the silver lining and hanging on to it like a metaphorical lifesaver. Because COVID-19 has affected our job security, the food supply chain, and proved that even the strongest pillars of society can sway with the strong winds of change, we are becoming more aware.
We are aware of our resilience, of the unsustainability of our modern supply system, and best of all, aware that we can only truly have complete trust in our fellow neighbors, our families and in ourselves. Close and personal relationships with our communities have proven to be more dependable in these times of trouble, and the responsibility of our own livelihood rests heavy on the shoulders of numerous people around the world. This has prompted a new generation of growers and doers. The younger generation Z and millennials are feeling tremendous pressure to look for other ways of sustaining themselves and many have turned to growing their own food, or turning to their community and buying from local farmers and butchers.
It is my passion to help stoke this fire, if we as a nation are able to bring healthier and fresher food to our tables from local growers and farmers or from home we will severely alleviate the growing pains our food supply system is bound to feel as our population continues to climb. Ultimately, the goal is to decentralize food supply and raise our standards of our producer's stewardship to their communities and employees. Less fuel will be spent hauling commercially-produced lettuce across the nation, less water will be demanded and consumed on massive monocultures, and our dollars will directly benefit our neighbors, not the distributors and retailers that can further contaminate the food we eat.
The most important message is to vote with your dollar. Support the systems that surround and benefit you. Buy from your farmer neighbors; befriend the homesteaders that sell eggs or produce, visit farmers markets and deepen your relationship with the food you eat. The more that you do this, the more a community will prosper and politicians will follow the lead, not the other way around. You will find that food tastes better when you know the farmer and these deeper communal relationships nourish so much more than just your body, they can help save the world.
Cheers and Good Growing
Yaupon Holly, aka Cassina, or the less-appetizing Latin misnomer Ilex vomitoria (it does NOT cause vomiting) is the only caffeine containing plant native to North America. Yaupon is extremely common in Southeastern Coast of North America. Many have seen its distinguishing red berries in the winter, but few have realized the potential Yaupon has to make delicious caffeinated tea that many say tastes better than its cousin Yerba Mate. It's the perfect solution for those who want to reduce their dependence on commercially produced caffeinated beverages and save money at the same time!
The first step to brewing a hot cup of roasted Yaupon tea is the most important; you must correctly identify the leaves, otherwise you can have terrible tasting tea, or brew something that can potentially make you ill. Fortunately for us, Yaupon is very easy to identify. To be absolutely sure you can wait until the later fruiting seasons in the cold and identify the Yaupon by their red or sometimes yellow berries, but this is not the best time to harvest as the leaves are bitter. Alternatively you can pay attention to their unique leaf structure. Look for their small oval, scalloped leaves which alternate on the stem.
Yaupon Holly can be prepared a number of ways, freshly dried, roasted, or toasted. Here I will document the process for my favorite method of roasting for a rich, malty taste similar to Yerba Mate.
Comment your favorite Yaupon Holly preparation methods and tea recipies!
Cheers and Happy Growing
Most Common Nutrient Deficiencies in Hydroponics/Aquaponics and How to Remedy Them
Aside from the most common killers of hydroponic crops (Read it Here), nutrient deficiencies can be harder than finding your way through labyrinth to correctly diagnose. Luckily hydroponic nutrients are usually nutritionally complete formula so the issue is more simple to approach, Aquaponics on the other hand is a more nuanced agriculture system with more nutrient pitfalls.
Here's a great resource from MSU to visually identify your Mobile and Immobile Nutrient Deficiencies. Know the difference between immobile and mobile and how they affect new and old growth!
The first thing you should verify once you identify a nutritional deficiency (be sure to completely rule out pests and disease!) is your pH. It is critical to have your pH at a level around 5.5-6 in hydroponics and 6.5-7 in aquaponics. This is crucial for your crops to be able to absorb the essential nutrients that keep them healthy and producing.
HOW TO SOLVE YOUR HYDROPONIC OR AQUAPONIC pH PROBLEMS:
While the solution for you aquaponic pH problem is more complex (check out our entire blog post deticated to aquaponic pH problems), it's a little more simple in hydroponics as you do not have the biological factor of the fish. For the most part, you'll use muriatic acid to drop your pH if it's above 7, and to fine tune it to 5.5-6 use phosphoric acid. Remember to do everything VERY slowly as you don't want to overshoot your pH. To raise your pH I would use Potassium Silicate or Potassium Bicarbonate.
If your issue does not resolve itself once you correct the pH, or if your pH was perfect to begin with, this is where things can get interesting. Unfortunately I mean this in a convoluted, much more complex way that many would rather call "frustrating". This is due to the fact that plant nutrient solutions must exist in the proper ratios of nutrients. Because plants take in nutrients through ion (negative or positively charged) channels, these ions must exist in the right amounts so they don't over-compete with each other and "lock" each other out. Paraphrasing to give an example, since Calcium and Potassium are both positive ions they will compete with the same positive ion channel so too much calcium can give you the visual deficiency effect of not having enough potassium! This of course is simplifying biology a bit, but the point is that your ratios of each nutrient must be correct, otherwise identifying your deficiency is nearly impossible.
Now that you have furthered your understanding of why deficiencies are hard to detect, let's talk about how to approach the solution. As I've mentioned earlier, your first priority is to check you pH. Afterwards, ensure your nutrient schedule is not due for a hydroponic water change, if applicable. These are the equivalent to "have you tried turning it off and on again" in the soil-less agriculture world. The next step is to then identify the affected leaves; if the older leaves are affected that will tell you that you're dealing with an immobile nutrient such as
If you find that the younger leaves are affected then, as you can guess, mobile nutrients are your point of concern.
Your issue is most likely either Nitrogen, Phosphorus, or Potassium since those are used the most. If those are not the culprit, the second most likely group is Calcium, Magnesium or Sulfur. If those miss the diagnosis then only the micronutrients are left. Look at deficiency charts and flow diagrams specific to your crop and pay attention to how younger and older leaves are affected and you will be able to correctly diagnose your specific problem.
If you have any questions, or need help with your deficiencies drop your comments below and we'll be sure to take a look!

3 Reasons Why Your Plants Are Dying: Common Killers of Indoor Hydroponic Gardens
The only thing more frustrating than a dying plant is having no idea why your plant is days away from biting the dust. Since gardening can be a patience demanding practice, it's no surprise many shed tears when they lose a beloved plant 3 months into its 4 month life span. In this short guide, I'll run through the most common killers for the beginner or intermediate hydroponic farmer so that you can learn from the mistakes of all the heartbroken growers who had to learn the hard way.
Before I begin detailing what can go wrong, let me preface this post by restating a few tenets of Integrated Pest Management (IPM) as they apply to your indoor garden. First and foremost, a bad growing environment fosters a weak plant and a weak plant is the preferred target of any pest or disease. Nutrient deficiency is never as fast and brutal to plants as pests or disease so keeping your plant happy is the surest way to avoid a quick disaster. The quick rundown is as follows:
Keep your plants in an area where it's comfortable for them; not all plants tolerate the same conditions so do your research. Brassicas and leafy greens generally like it cooler (55-75 F) while fruiting/flowering plants like it a tad warmer (70-85). Humidity is also an important factor as fungi and bacteria love cool, moist conditions so try to keep your humidity low, especially in cooler climates. A great method of controlling humidity is to have good air circulations using fans or passive vents. Hot air leaves from the top, pulling cooler air from the bottom, remember this when you're configuring any vents and keep in mind that if any bugs are around your area this is also where they can enter! The next step is simply to monitor your grow area as thoroughly and often as you reasonably can. Once a day is optimal, but you can get away with less once you become more familiar with the environment. Keep a log of your nutrient addition schedule, take pictures, and inspect the plant closely for signs of even the smallest bug, fungal spore or bacterial spot. Take it easy, no need to whip out a magnifying glass, but these efforts are your first line of defense. Now on to the carnage....
1) ROOT ROT:
If there ever was a wanted poster for the silent killer in hydroponics, Root Rot's fungal mugshot would be plastered front and center. Your plant can go from healthy to drooping in a matter of days, leaving you perplexed as there are no signs of disease or pests on the leaves or stem. Only once you pull your plant out you'll see the blackened, slimy aftermath of a root system ravaged by this fungus.
tIn this case the best offense is a good defense: Root rot loves a hydroponic solution lacking in oxygen and beneficial microbes. Sizing your container properly so that your roots don't mat together and form dense knots will also prove effective in keeping your roots inhospitable to Root Rot. Beneficial microbes also serve as defensive competition for the surface area on your roots and help digest and break down any dead material before root rot can sink it's teeth into a buffet of decaying roots. Adding oxygen through the use of air stones and an adequately sized air pump is an absolute must to keep your plants healthy growing optimally. Last but not least, adding about 3 mL of 30% hydrogen peroxide for every liter of nutrient solution [3 mL/L] can halt or deter root rot from setting in and is my preferred line of defense prior to using the expensive big guns like Cannazyme or other digestive enzymes to break down decayed roots.
2) POWDERY MILDEW / DOWNY MILDEW / GRAY MOLD
I'm clumping these three fungal delinquents in one group because they all have several key signs and prevention methods in common. While each type of mold may be specific to different varieties of crops, there's always one ready to invade your lush plants at the first sign of weakness. These three (and similar perpetrators) are lovers of the extremes: too dry, too cold, too wet, and too hot.
This terrible trio loves the damp micro-climates of stale, un-circulated air under leaves, around bushy stems, and in your precious flowers and fruit. Anything that's wet, decaying, damp combined with a climate that's too cold or hot is a breeding bed for one of these fungal plant diseases. Distinguishing between the three is not as important as knowing your defenses. Keep your plant well trimmed; any leaf that is not actively healthy and not contributing to photosynthesis (i.e. shaded by other leaves) can generally be trimmed and discarded to increase air flow in your plant. Circulate the air with oscillating fans to keep the environment free of damp, stale air. Any signs of this disease or decay should be dealt with by carefully removing the infected leaves as you don't want to spread spores, and discarded in the trash. DO NOT COMPOST DISEASED LEAVES! Other preventative measures such as foliar compost sprays and/or biopesticides such as B. Subtilis (Serenade) are great options to stop these molds from colonizing your crops. One final note is to harvest your fruit as soon as it is ripe; mold will blossom on old and rotting fruit.
3) THRIPS / MITES / APHIDS / WHITE FLIES
OH MY! Again, I've clumped these pests into a group of the most common culprits for giving gardeners a headache. These critters may be very hard to spot for the beginner grower before it's too late. Keep an eye out for the favorite congregation points: Fresh new growth, undersides of leaves, and in the nooks of branches coming off the stem. Other obvious signs of spider mites are tiny black dots that leave web-like material (hence spider) leaves and stems. If you're growing indoors you will be much less prone to these pests, but do not be complacent and continue to do close examinations of your plants. Be wary of introducing store bought plants to your environment without thoroughly checking for signs of these pests as many nurseries and grocery stores offer infested plants unknowingly to customers. Look out for the signs of pest damage by looking for abnormal leaf curling, puckering, discolored white spots, or yellowing/dying leaves. Anything short of a healthy plant is a reason for suspicion so keep your eyes peeled for the tiny critters.
While these pests are only deadly to your plants at levels of heavy infestation, their initial appearance should be recognized as a red warning sign to an imminent uphill battle should you not take it seriously. Action at the first signs of pests is your best option, aside from the preventative environmental management. Squishing aphids by hand, or trapping white flies in sticky traps is a great way to curb the growth curve so that things don't get out of control too fast. Using beneficial insects like lady bugs, predatory mites, and lacewings are excellent pesticide-free and organic methods of controlling pest invasions. Other options like Azamax and Neem Oil are good too, however many find the pungent smell of neem oil to be off-putting so many opt for insecticidal soaps derived from fatty acids to be their preferred method of pest control should they need a spray. Regardless of the method that works for you, the solution to an already infested plant can be messy, time intensive, and frustrating so your best bet is to keep your area away from pest entry points, and your plants as healthy and vigorous as possible as pests love a weak plant.
In short, these diseases can be a terrible fate for any gardener and their plant. If you run into any of these or other problems do not dismay as there is no such thing as failure in gardening, only lessons in ways to do it better next time. Keep your plant healthy, your environment clean and favorable, and monitor your plant as frequently as you reasonably can. If you keep good records and stay observant you'll have a much better learning experience should your grow be a success or a painful lesson. Remember to do your research on the temperatures and conditions that your particular plant prefers, and practice getting a good start as early as germination. Above all, never stop having fun. Enjoy the process of learning and growing as a horticulturist and you'll gain much more than just a harvest.
Cheers and Good Growing!
If you were to tell someone that they could grow their own tomatoes, peppers, cucumbers, cannabis, or other fruits hydroponically their first reaction would probably be to wonder how difficult, or expensive it would be to achieve. The fortunate truth is that hydroponics can be as simple as growing with soil, and much more effective at growing massive yields and incredible fruits, vegetables or medicine. Once you experience the power of your own green thumb you'll feel empowered knowing that you can rely on your own skills to supplement your life with the wonders hydroponics has to offer. Keep reading and by the end you'll have made a high-performing hydroponic DWC system out of readily available components. Speaking of components, let's lay them out:
1. 5 Gallon Bucket.
2. 5 gallon bucket net cup (I prefer the 6 inch diameter one)
3. Substrate (Expanded Clay, Coco Choir, Perlite, Lava Rocks, or other hydroponic media would work fine)
4. Power Drill with a 1/4 inch drill bit
5. Box Cutter
6. Aquarium air Pump
7. Air Stone
9. Hydroponic Nutrients
OPTIONAL BUT STRONGLY RECOMMEND FOR MAXIMUM PERFORMANCE:
11. LED Lights and Necessary Hanging Equipment
12. Fan (Preferably Oscillating)
Take your 6-inch net pot lid and place it on the 5-gallon bucket.
Drill a 1/4" hole on the side of the bucket, somewhere close to the lid. This will serve as a hole to run you air stone tubing through.
Fill the 5-gallon bucket half-way with Distilled (dH2O), Reverse Osmosis (RO) or Rain Water.
This step may differ depending on which nutrient mixture you choose. I'm using Advanced Nutrient's three part nutrient mix at 2 ml/L for the early stages of growth (1.5 months) and slowly increase it to 4 mL/L for the the remaining vegetative and fruiting stages. Simply read the nutrient labels and follow their instructions. General Hydroponics, Master Blend, Fox Farms, and many others have wonderful nutrient mixes for your different needs. After you properly mix your nutrients in, fill the rest of your 5-gallon bucket up with water. Some mixes may require you to fine tune the pH, but in Advanced Nutrient's case the final solution is always 5.5-6.0 as long as you use pure distilled or RO water. Mix your nutrients in a 1 gallon distilled water jug that is half full so that you can shake between nutrient additions.
Connect your air pump, tubing, and you airstone. Make sure you run the tubing through the hole in the lid before attaching the airstone. Plug everything in and insure that your airstone sits at the bottom of your 5 gallon bucket. LET YOUR AIR STONE SIT FOR ABOUT 1 HOUR BEFORE TURNING IT ON! The smaller the bubble the better as this helps the nutrient absorb more of that precious oxygen.
Put your plant in! You can start from seed and then transplant it in once it's 3 weeks old, or buy a young plant from a nursery or grocery store. The best time to buy young plants is at the tail end of the growing season since everything will be on sale. I got this Naga Viper pepper plant for only $4 at HEB! First Step is to check for diseases or pests. Once you ensure that your plant is a healthy one, transplant it by first cleaning off the dirt from the roots using a hose. You can be rougher than you think and don't be afraid if you lose a small amount of roots. A little left over dirt is okay too.
Now, simply fill up half of your net cup with rinsed hydroton then place your plant roots in the hydroton. Make sure they are submerged in the solution. Now backfill the remaining space with more hydroton and make sure your plant is supported. Give it a few taps to settle the hydroton if necessary.
ADDITIONAL STEPS FOR THE DISCERNING GROWER:
STEP 7: CHECK OUT OUR BLOG POST FOR LIGHTING TIPS
Hang your light source so that you can vary the height from the plant as it grows. Most, if not all of the respectable companies, include a light intensity map measure in PAR with their lights. This should tell you how PAR varies under a light at different heights and a map showing you how the PAR changes as you move from directly under the light to the sides of the light zone. For a high performing fruiting/flowering plant I'd recommend a PAR of at least 800-900. A PAR of between 300-500 is more than enough for any leafy greens or herbs. A simple trick to increase light around your plant is a simple grow tent with white reflective panels or screen. White generally reflects better than foil or reflective tape, contrary to what you may think.
Connect your lights to a timer. This makes it really simple as you can just leave for 2 weeks and come back to new growth (assuming no disease or pests!).
Add a fan to gently blow your plant and increase air circulation. This helps the plant develop a strong stem, and fight off any fungus or bacterial diseases that occur when you have micro-climates of damp, humid air. This is especially recommend if you are growing in an enclosed space with a large sized plant.
If you have any questions please don't hesitate to comment, I make sure to answer every question you guys may have! This is the best and cheapest way to grow a single fruiting/flowering plant, be it tomatoes, peppers, cucumbers, cannabis or squash!
5 Reasons Why Your Seeds Are Not Germinating: Quick Guide To Germinating Success
Gardening at home can be an incredibly therapeutic hobby that builds confidence in your abilities to work with mother nature. All this, to many beginner's dismay, comes after the hurdle of seed germination. It so happens that plants, much like animals, are the most vulnerable within the first month of their life and the degree of their success heavily depends on how well it started it's life from a seed. As with anything in life, it can be insurmountably difficult to succeed without the proper information so keep reading to find out the best way to germinate and start your gardening journey strong!
Let's start off with what may be obvious in retrospect: not all seeds are made equal. As an extreme example of this let's take a look at two wildly different plants: Arugula and Oak Trees. On one hand, Arugula seeds are barely larger than a a grain of sand and only takes about 2-3 days sprout. Conversely, a larger oak seed has a tough exterior and it takes 75+ days to germinate! What all this means is that you have to do your due diligence as an expectant plant parent and research what your seed needs to grow big and strong. Here's a rundown of some of the most important germination factors in no particular order:
2. Planting Seed Depth
3. Light or Dark Germination
4. Nicking or Pre-Soaking
1. Temperature plays a huge role in plant metabolism and, along with moisture, greatly affects whether a seed will germinate or not. Many brassicas (Lettuce, romaine, arugula, chard, kale) like cooler temperatures between 65-75 F (18-23 C). As a rule of thumb, warmer temperatures are better for other seeds as it speeds up plant metabolism, but there is a definite point where it's too hot. To be safe, you should not exceed 85 F (29 C). Many gardeners swear by a germination heating mat under their germination tray that is set at 85 F to quickly boost germination success.
2. Planting Seed Depth can vary a good deal between seed varieties, but as a rule of greens thumbs you can expect that the smaller the seed, the more shallow the planting depth. For example a watermelon/cantaloupe seed does great about 1/2" under the soil, but smaller seeds such as lettuce prefer a much more shallow 1/8". You should note that most seed packets will specify the planting depth so make sure to read it in its entirety!
3. Light or Dark Germination is an often overlooked variable when germinating plants. Luckily most edible Brassicas and other food crops prefer dark germination so it's not often that incorrect lighting is the reason your seeds may not be germinating. This is true unless you're planting the small amount of plant families that prefer light during germination. These include many popular flowers like petunias, begonias, and other plants like the coleus and ficus.(https://www.thompson-morgan.com/effect-of-light). As for the dark-germinating plants, it's best to keep them in a humidity dome that is in a dark room or closet, or simply cover with a light-blocking material. As soon you see the first signs of the plant breaking the surface of the soil be sure to bring them into the light to let them know they made it to the sun!
4. Nicking or Presoaking (also know as scarification) is a process used by farmers on seeds that have tough exterior shells. Nicking and/or presoaking encourages the seed to start breaking out of it's shell and can greatly decrease the time of germination for certain seed types such as Hibiscus, morning glories, and some Solanaceae plants. The rule of thumb is if the seed has a waterproof coat, it may benefit from nicking and presoaking. As a caveat, be sure to nick the side of the seed opposite of the hilum, the little dot where the seed was attached to the mother plant. Harming this "belly button" may damage the seed instead and halt any chances of germinating!
5. Watering is often the most difficult parameter to get just right when germinating your plants. Too much water and you'll promote harmful bacteria and fungi that will decay and rot the seed, too little and the seed will dry out and refuse to germinate. To remedy this, many farmers turn to substrates that have the optimal water retention or drain well if over watered. Coco choir is my personal favorite as it is hard to over water, but many have had success with a 50% soil and 50% perlite mixture to start their seeds. The substrate should be similarly moist to a freshly wrung out towel.
My preferred way to begin seeds it to use a germinating tray from companies such as Jiffy. it comes with a tray of compressed coco-choir pellets that you simply hydrate, place the seeds at their correct depth, and cover with a moisture dome then place them in a dark and warm closet. With this information you now have the knowledge to successfully start a seed at your disposal. Once germinated keep an eye on your lighting environment and watering. Carefully observe your seeds as they will communicate any problems in their own language; if a plant is stretching (stillating) it needs more light, if the plant is drooping you're either giving it too much water or not enough.
Finally the biggest piece of advice to be a successful gardener is to keep at it! Each failure is actually a lesson in disguise. Fail hard and fail fast and you will quickly learn to speak the language of plants faster than you can imagine. If you think of gardening as a trial in patience, humility, and gratitude for life and you'll be surprised how much plants are helping you grow just as much as you help them.
Cheers and Good Growing!
Hydroponics carries a certain stigma within popular culture. Mentioning hydroponics conjures images of advanced nutrient regiments and a scientific approach to agriculture fitting for advanced applications or cannabis. This unfortunately is a stereotype that can easily discourage a beginner or intermediate gardener, but fret not, continue reading and you'll soon realize that hydroponics can be as simple as you make it.
To quickly preface, plants generally need a just handful of vital things:
3. Oxygen/Carbon Dioxide Gases
5. Adequate Humidity and Wind Conditions.
These conditions exist in optimal amounts, but as long as a plant has the minimum of ALL of these it WILL stay alive. What this means is that you don't need insanely expensive hydroponic systems and state of the art lights. Additionally you can save yourself from the whiplash of nutrient marketing as plants will thrive on any simple hydroponic nutrient mix as long as these conditions are met.
So, this is all to say that you can get creative with it! Most leafy greens such as lettuce, basil, mint, arugula, kale, chard, etc. grow extremely well in the most basic hydroponic systems. As per the kratky method, you can achieve amazing results with a 1 L plastic (foodsafe!) bottle, some general hydroponic nutrient mixture, and a well lit south-facing window.
IIt typically gets more difficult to grow fruiting plants as you have to account for larger growth, more nutrient needs, as well as stronger light requirements. Still, you can easily grow tomatoes, cucumbers, cannabis, and peppers using a slightly larger, more advanced system. My favorite is using a 5 gallon bucket with a modified top to fit a large net cup filled with expanded clay media, perlite, coco choir or any other hydroponically compatible substrate. The second most essential difference is a source of air for the larger roots. This is as simple as getting a small 10 gallon aquarium air pump and an air stone and throwing that into the bucket! Easy, right? Finally, since fruiting plants generally need more light, they'll require a grow light to achieve the best results. You can technically pull this off without one in a very well lit apartment, but for those with limited window options LED lights are the best choice. In the pictures below, I show that it's possible to grow with the cheaper "blurple" lights sold on Amazon (Vivarspectra and Mars Hydro), but if you're looking for the best results and highest yields I recommend the Spider Farm LEDs from Samsung or the Horticulture Lighting Group's Quantum Boards.
The main point I'm trying to make here is that hydroponics is simply a method of growing a plant without the use of soil. The biggest take away is that it can be as simple as your needs: if you just want to grow some leafy greens to add a splash of delicious flavor to your daily salad it's as simple as using a 1 liter bottle and a very basic hydroponic nutrient mixture. Fruit, legumes, and cannabis take a little more effort, but the reward is generally of higher dollar value so you can easily justify spending more money to make you system a high-performing produce machine.
While it's incredibly fun to experiment and let your creativity lead the way, you can always contact us at Kodaponics and set up a very affordable consultation to insure that your system is successful. If you have a system or design in mind, drop us a message at email@example.com and we can help you make your gardening dreams a reality!
This is a quick and simple guide to making a hydroponic mason jar using the kratky method. This is one of the easiest home hydroponic set ups you can make and most, if not all of the supplies can be bought in your local gardening store. Whether you are a beginner or just looking to add something to your windowsill garden, these easy to make kratky jars work great!
You will need:
Start by filling your 1L bottle half way with distilled or reverse osmosis water. Measure out your nutrients to get the preferred concentration for your crops. In this case I use 4 mL/L of Advance Nutrient 3 part grow. Follow your specific instructions for 1 L of nutrient solution and it will work. Measure each component in the correct order and shake well between additions. Make sure all nutrients are dissolved.
If you are not using a pre-made nutrient mix and will be using individual nutrients, add them in the following order in (g/100 L). Close Cap and shake well between additions. Use as soon as you make it, and discard the excess in your houseplants for some great growth!
Shoot for a pH of 5.4-6 and an E.C. of 1.4-2
Fill the rest bottle up with your distilled or reverse osmosis water and shake the hydroponic mixture once.
Simply place net cup into mason jar with the top lid removed. Fill the mason jar up so that 1/4th of the net cup is submerged in the nutrient rich hydroponic solution then place your plant in. Almost done!
Step 4 Final Touch
Add a sock or makeshift covering for your jar to keep the light out. Light in the jar will lead to algae growth. Algae is a sure way to have your nutrients stolen from your crop!
There you have it! Once you get the hang of the kratky method, every recycled jar has the possibility of becoming a small hydroponic system!
If you would like some extra help starting your own home hydroponic kratky jar then take a look at our Zen Jar! It is a DIY kit that includes all the materials needed for you to get started from home. It even includes an interactive plant growing calendar so you can easily keep track of how many days your plant has been nursing and how much longer until you start seeing flowering or fruiting depending on your choice of seed. Get started today and happy growing!
The Self-Sufficient Survival Garden: The Kratky Hydroponic Method and Making Your Own Hydroponic Mixtures
In an objective-based view, one can say that hydroponics and aquaponics are simply different routes to the same destination; growing plants without the use of soil. From my experience the more nuanced reality revealed two niches that better suited one or the other method. Of course there are always exceptions to the rule, but generally hydroponics is better suited to massive commercial food production facility especially when the sizes exceed 4-5 acres. Hydroponics allows farmers to fine-tune their nutrient formula to achieve incredible consistency in their quality and quantity while maintaining a highly sanitary environment. Aquaponics, on the other hand, forces farms to divide the focus between the plants and the fish. Large aquaponic farms must devote a large amount of time, money and resources to keeping the fish healthy and producing consistent nutrients. Aquatic diseases are a major concern and a large investment must be made to control temperatures, otherwise the drop in temperature will slow down the metabolism of your fish.
Aquaponics shines in agricultural categories such as non-profits, personal business sub-three acre farms, hobbyists, commercial decor/aesthetics, and applications where emphasis on natural biological systems in harmony is desired. The small 24 m x 44 m system could easily boost a communities' access to healthy vegetables, fruits, and fish for very little individual financial contributions while serving as practice grounds for budding agriculturalists and environmental biologists. The real significance of aquaponics lies in its unparalleled sustainability; even more so when in conjunction with other natural cycles such as composting, outdoor gardening, and chicken keeping. Food waste from harvests can be used to raise black soldier fly larvae for chickens and the fish. Solid fish waste and chicken waste can be returned to composting or used in the outdoor garden. Solar can be introduced to take small systems off-grid, effectively un-tethering a family's (or community's) dependence on commercially available food.
Finally at the sub 10 gallon range, hydroponics takes the lead once again due to the convenience of measuring out the perfect concentrations of nutrients for your plants. It is possible to grow a healthy bibb, kale or arugula in 2 L bottles using the kratky hydroponic method. This makes it optimal for absolute beginners to begin growing their own food at home and serves as an excellent introduction to soil-less agriculture.
Regardless of the method, I am certain the future will see a rise in both methods to sustain the growing demand for local, healthy produce in a more environmentally-conscious market.
