Hello smokers, it's my firsty post here ;d, so lets get to it.
I was going to build a growroom for 4 plants in my attic, but I just measured a temperature there and it goes down to 7.8 C (around 46F), so I guess it wont be possible to grow anythin there without heating??
So then I've changed my miind and I'm looking forward to build it in my bedroom and keep mother along with young clones in a very separate box (MH light). Does it sound reasonable?
Also how big should the flowering box be if it would have to fit 4-6 plants (probably AK-47

?
