So this is my second official grow and man after the first I thought I knew something... I couldn't have bn more wrong... my location dictate that lights on at night becuz day temps are unmanageable. Sooo I've learned on this grow that when lights off humidity spikes. Especially if the air circulation it's running the same as the day settings.. so turning exhaust to lowest setting allows the temo to go up a degree or 2 and the percent of humidity drops by 2 or 3 for every degree..( from what I can see) 75 degree night air allows humidity to fluctuate between 50 and 56 percent.. if I turn exhaust up to 40 percent humidity spikes to 68 amd temp drops to 65.. hope this helps someone in the future.. trying one 6inch exhaust 2 tents ( 2x4 and 2x2)..
