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.
