18 hole hydroponic setup

This is a tutorial for my larger hydroponic setup. The setup allows 18 holes for plants; this particular setup has 5 different varieties of greens: arugula, kale mix, cilantro, spinach and green onion. 

This is a very simple project however requires basic understanding of hydroponics. The ph level in water is important as it helps imitate the environment of soil-based gardening. The liquid nutrients imitates the nutrients in the soil. You can lower ph levels naturally using lemon or lime juice. The plastic of the tote is important as well make sure it’s food grade; p5 is fine.

Instructions

1. Take a 1 1/4″ hole saw and the sterlite 16 qt and mark your first hole
2. Then use the hole as a template for the hole grid
3. Drill a hole for the airline for the pump, make sure it’s big enough to not pinch the airline
4. Drill a hole for the grow light
5. Count the baskets you need (18 in this case)
6. Fill the tote with water and measure the ph level, adjust as necessary
7. With the last cup of water, soak the sponges for 5 minutes, pour remaining into the tote
8. Place everything in their holes
9. I planted two seeds for every basket to increase chances of germination
10. Wait 7-10 days for peak germination
