Where to grow??

Hello all ! Just trying to get some input as to what i should do , i live in a huge house that has plenty of places to start growing , basement , about 3 closets , but it is about to be getting cold so the basement does'nt sound like such a good idea considering i have no heat in the basement . But it has more room , and less of a chance somone in my household discovering them . Im getting reay to grow about 5 plants , the closet space im thinking of in my room has about a 5' x 5' space , But it will be near impossible to cut down on the smell , any suggestions on what i should do?

i would use the basement and but a propane heater

you could get a small space heater. If you can ventilate it, you can also filter it.

if your basement temps stay above 50, many do, it's real a good place - if a bit cooler, it won't take much to bump it up a bit
