How can I reduce the heat in my 5x5 tent (650w light bar/6" ac Infinity and a ton of fans) without AC? Do I have to leave tent open?5x5 tent is in a kind of lung room (utility room) that stays around 20C/68F. The tent always seems to be at 30C86F with lights on. Ive added and moved fans, opened more intake vents. I have AC, but its -25C/-13F outside. Id like to drop the daytime temp 5ish degrees for flower.

Can I change my autoflowers light cycle withou reducing their yield significantly?I am having humidity/mold problems and was thinking of changing the cycle so the grow goes off at noon ( currently it goes off at 1am and its winter and gets real cold with 88% humidity).
Even if I stress them, it would be better to not have mold than reducing the yield, right?Other. Mold

I've got a question.. I need a new light for vegging (only) in a 80x80cm tent.
I am thinking of eather the LIGHTWAVE T5HO 60 CM (48W) or
MarsHydro TS 600 (100W)
Has some one experience with those lights? Is it worth spending double on electricity with the MH?Setup. Lighting

Tent too hot?I added two blurple lights - I'm not sure how much they're helping growth but they are definitely making the tent hotter - about 5 degrees F. I have a fan blowing at the bottom of the tent and at top over the lights but I'm worried that it might be too hot. Should I ditch them?

Low Humidity and high temp or high humidity and low temp?Do you think it’s better lower temp and higher humidity (like 27 degrees c and 80 % humidity) or higher temp and lower humidity (like 29 degrees c and 60 % humidity)? I’m just waiting for the humidifier but in the meanwhile I have to fix somehow. Thanks!Week 1

Does anyone have experience with colas that have been severely light deprived, yet still have trichs?My ghost nug grew up on the side of the tent blocked from light. She has trichs, looks super light yellow (see pics). My question is, wouldn't this be desirable? Less chlorophyll to wait on before smoking? Has anyone tried to maybe light deprive parts of their colas?
