Step 2: Liquid feed container
Lets get started, first drink up the delicious juice, now clean and sterilize the bottle by adding a few drops of chlorine in and filling it up with water. Place the bottle cap on a flat surface and drill 2 holes that will fit the 1/2 inch hose and air line snugly and I mean snug you don't want air leaks, so after you finish fighting with the hoses and the bottle cap, you can then go ahead and apply some hot glue to finish sealing any air leaks that might occur. Assemble it all together and walla!!! you have the container that will hold the plant food. (please refer to the pictures)
