I am thinking about making a veg cab but I have a problem, the only place in my room I cen put it has no outside ventilation. But I also don't want any smell in my house at all!!!!!! How would you do this?
Most of the time, at least in my experience, there is no real smell during the veg stage. Smells like any other plant until you flower it, then you will have a smell to deal with.
Like small said typically don't need it in veg...but some plants do smell still. Couple options get a small inline fan and carbon filter to exhaust into your room. Or you can try some Ona Gel
