If you want to avoid root rot keep your resevior moving with a submersable pump that has an adjustable power head. You can move it around where you want, it sucks in air and spits out bubbles with the water. If your res is too deep though it won't suck air and you'll need to inject it with a small air pump. And don't let your nutes get too hot.

GK:can I switch from aeroponics to soil during same grow I had a problem where my plants got root rot in my aerojet aeroponic setup(i think because the roots just sat in the water and it was warm, eventhough I changed the water every 3 to four days). My solution: A) elevate the trays on one side to increase drainage B) When the roots grow out of the 4inch net cups tansfer to a 80% perlite/20% peet moss My question is do you think this is a good idea, also if it is what extra precations should I take regarding ph of soil and ph of water.
