Thanks Mr.furley, I water just till i get a descent , even leakedge. But it does take a little while for it to dry. Longer then usual.. Alomost 4 days.The fan below is to drive my co2 up. But i see where you going with that. But all fans go off on down time for 6 hours..18/6 with 3 plants in 3x3x5 tent with a HLG 300 Led fixture pushing 280 watts full spectrum.I have it about 24 inches above the canopy. Thats my new toy.Lol..The roots are not really growing out yet, but are visible.I'm transplanting fom 1 gallon to 5 gallon on my next grow i started. But these start and finish in the same pots. Temps stay about 85 right now, Not sure about temps when lights out. Gotta keep sealed with co2 but i think 85 is ok. Humidity around 60%..What type of water is best to flush with? And do i use cal-mag during flushing?? I bought some purified water, and was gonna use that. I was a little surprised how high in ph it is.. bout 8.0
