@1Right_Angle, it’s mainly due to the weather. This setup is in an uninsulated shop. The shop has a filled attic so it has that going for it. I have one exhaust fan on the outside top of this tent exhausting out. I seal it up right and have a 4x4x8 and a 2x4x5 beside this tent with exhaust hoses going from them to this tent. In both of those I have plants, lights and 1 600w floor heater each so I’m exhausting warm are into the tent always. I’m guessing the temps to be honest but I’m sure it gets pretty cold. You can see the purple cold stress.
