Step 2Inspect Toilet Tank
Bracket - It must support an inverted 2L bottle (in this design at least) with no physical contact between
tank water and grow chamber drainage and must allow relatively undelayed drainage back
into tank. I chose to replace the tank lid with another horizontal surface through which I could
drill a hole and mount the bottle. Plastic is easier to drill and replace than porcelain.
Fill Tube - Simply mate the fill tube with the tank's existing fill "spout", whatever it may be, in order to
divert thte water so that we can insert our "grower", in series, into the existing pathway of the
water before it fills the tank.
