Yep photoperiod canna for sure, I am of the philosophy that any stress in autos causes them to basically stunt in some form or fashion. I am trying to stay between 70 and 80 at all times. Now that may prove to be very difficult as it does get to -40 here at night. But I am confident that I have a last resort option in the foam, because that is giving me 2 inches of foam and plywood between the indoor space and the outdoor cold. I am just trying to get it done so its the least amount of workload on me each day as it is just me. Putting up foam panels each night will be kind of a pain in the arse, but one I am willing to do if need be lol
