Small grow room not clean but is what i have

Well I recently made a tiny grow room with my mother. It is not a clean room but the plants seem healthy... What is a good tempature to keep the room? is 72 f Ok? How about reflective materials. Is silver better or white? Is miracle gro a good idea? I have heard both sides. they grow faster with it but apparently it reduces the potency of the herb.

70 to 80 degrees is great. I would use mylar, or paint everything high gloss white.You can use miracle grow but there are definetly better nutrients then that.

Yea i just started to make mine and painted everything in vynil silk brilliant white
just waiting for the floor to dry
