You can go all the way up to a constant FLOW over hydroton, 24/0, and your system becomes NFT. It's a really sweet way to do hydro, and that's what I run myself. I've got some threads in the grow logs section that show the potential problems etc. with that setup.
stinkyattic Reviewed by stinkyattic on . A little Help with the Drip I'm using hydroton in the pots and I put the plant in the rock wool in the middle of the hydroton. Im using GH nutes I want to know if I can leave the drip going all the time when the light is gone? Right now it is watering 4 times when the light is on and 2 times when off. Spread out evenly. each water is 20 min long. The plants are doing fine, growing good. Do most growers leave the drip on when the light is on? I am growing Brainstorm (Northernlights X Haze) and Ak-47 X C99 Rating: 5
