I dont think heat will be an issue, its sitting at 72°f right now and I have a 50w reptile heater on in the tent. I know when I turn it up to 100% heat will go up, but I'll just turn off heater. In summer it's very cold downstairs from the AC. It normally could be a little warmer then too, dont think it will be an issue. It's nice to know if I needed to I could tho, and will monitor it. I tell ya what... there will be nowhere to hide from light in my tent with SP 3000! Bright as shit even at 50%.
