Divestoned,
Now I know why my roots looked so bad at the end of my last grow. I use drip irrigation 15 min off, 15 min on 24/7 thru my 1st two grows! On this last one, the roots were very dark and slimy. Harvest was still pretty awesome though.
Think i'll try one 15 min drip half way thru the lights out period and see how that works. Don't remember where I got the 15 on 15 off schedule, maybe watering too much all the time? The thought of my girls drying out scares me more than overwatering.
Great advice at any rate, thanks!!
