Hey guys! after numerous threads on the 420 forums, I have my lights selected as well as my hydro kit. Now, I want a grow tent. I will be using a 150w compact HPS light and a PowerGrower Hydro kit. Now, is it worth spending an extra 150 in getting a Co2 filter, fan, duct... for my grow tent or can I just use an oscilating fan to keep things cool/reduce smells? I would only be growing one plant at a time, and starting flowering when its 6 in. to keep the plant extra short. Any advice is extra appreciated
