Not sure about any of the set up, except I know its new and never used!!! A buddy of mine bought it new a year ago, set it up and his wife freaked out and told him to get rid of it. So I got it for a fraction of what he paid for it, set it up to start a breeding project and my seeds came and my main tent was full, so I'll use this set up to complete the grow, wipe it down and reverse a few males for pollen later. It is a sweet little set up!! It will be a little crowded, but will take a stab at some lst and get some mini bondage going on!!
Odorsok, I read they are ok, but I'll find out. If I start to smell stuff, I have a brand new phresh filter out in the garage for a back up.
