Lid with Holes
Build your own Hydroponic System Part 2
Standard Airline Tubing
The tub I bought conveniently already had 2 holes in the handle part that were just the right size to accommodate the airline. If your tub

does not have these holes you will have to drill your own. If you have to drill the holes, one on each side, try to make them just large enough to snugly fit the airline.

Now feed your airline through the hole and connect your bubble stone(s) and feed enough airline through the hole to have your bubble stone sit flat in the bottom of the tub.
I found once I put water in the tub and turned on the air pump the bubble stones tend to want to float a little. So you might want to use a non toxic waterproof glue and glue the bubblers to the bottom of the tub. I just let mine float as they only float about an inch off the bottom.
Bubble Stone in tub
If you haven’t already guessed the purpose of the stones is to keep oxygen in the water so your plants don’t drown.I use two bubble stones in my system but you could probably get away with using one. I just wanted to make sure there was plenty of oxygen getting to the root of the plants.
zip tie lid to tub
The next thing you have to do is drill some holes through the lid and the tub and zip tie the lid to the tub. The best way to do this is to put the lid on the tub and turn the tub upside down. Now drill the hole from the underside of the lid. Drill 2 holes on each of the long sides of the tub evenly spaced.

The purpose of the ties is to secure the lid and to keep the the sides from bulging out from the weight of the water. You can add a zip tie in each corner if you want. My tub has snap in sides so I didn’t worry about putting zip ties on the short sides of the tub.
My next post Build your own Hydroponic system part3 will show how to modify the Plastic cups to work with this system.
