yeah, fridges are extremely well insulated! which can be a good thing and a bad thing! haha...BTW...what are your ambient temps like at this time of year???
SLB
Ambient temps are air conditioned at 75 degrees so no worries there, it won't get worse.
Yeah, mini fridge is less than ideal as I have learned. Next time I'll be starting over with a new and slightly larger setup. This has just been been for practice so I'm good and ready when I decide to go for a larger light. I consider this grow and my last grow shakedown grows. Next time I'll pull out the stops a bit because I'll have my own space. To be honest I really have no reason to even bother. I have mmj so I have access to fantastic bud, but I guess there is something about growing that I enjoy. Its kind of like brewing your own beer.
