Opie I noticed you said the roots need as little water as possible..I'm curious how much that would be..i'm a noob and am doing my first hydro setup..Seeds are germinated and am going to begin tonight..I have a 5 gal bucket with four 3" netpots in the top..i have a small pump/powerhead hooked up to a small sprinkler on top that goes 360 degrees and will hit the bottom of the netpots..How often should i run this sprinkler? And how many times a day?? THANKS SO MUCH!!!!! I appreciate any help offered..
