Temperature Control?

Indoor tent growersn How are you cooling the tent?

I run a two tent grow. One with a mars hydro led and another with a king led. Lately they have been running the temp up to the 80s in the tents. I have filters running and fans. 20 on 4 off Autos.

What are you using for Temperature control??

I’ve been trying to develop a cold air intake for summer I think i have it dialed in… Involves Ice bin and some extra ducting work … Dyi style… How old are plants… 19-5 is a good number to start with

I placed a 12000 btu ac in my grow room window to help keep my temps under control, and I also run my lights at nighttime when the temp rises outside @ryanb.

They work amazing

What size fans? 450cfm or bigger or smaller. 4" 6" or 8" ducting? Where is your filter in the tent? How cool is the air going into the tent? Hows is it getting into the tent.
