ventilation is a problem with living in a city and in a apt,I have a ac venting in that is controled with my AIR-3 for now,no heat issues, more smell and having the lights on while im not home problems
Ive had no issues with my co2,my controler(AIR-3) also has a co2 gauge,its self severing,all I have to do is refill,that was a good buy.keeps the rm at 1400-1500
my tent is in its own rm(so I guess I didnt need to buy 1) but it has worked out, my clones now live in the tent(bought em there own light) because my plants got to tall(what a wounderful problem!)
even tho its alot of work I must say Im having a blast,had no idea this was going to be a hobby.
