Damn, such a nice update. That nightmare diesel is crazy. Is that under a 600?
Sitting under a 600 hps ushio in an adjust-a-wing. I wasn't totally sold on em but my buddy swears by them and had to shut down his operation momentarily so I'm giving them a spin. it's cold in the basement and the hoods put out a little radiant heat. I have a few 6inch clips fans in each tent to move things around.
Depending on the tent, the temps range from a low of 60 to a high of 75 depending on on outside temps. It's supposed to get really cold tonight and tomorrow in my neck of the woods, I bet I see sub 55f with lights off. Each tent is sitting on an inch of insulate foam board to keep the pot of the concrete. I also use the board in smaller square chunks to stack and keep the canopy level.
