Here in the UK (Midlands) the temp for tomoze is 33f day & 33f night & RL is 100% .Needless to say my humidifier(in my growroom) hasn,t run @ all for months.I do get condensation occasionally on some of the plants & a Zygo had some mold but i,ve increased the air movement & added bacteriacide to the water in my gravel trays.Everything is honky dory again.
