Hiya I tried looking up the CFM of the scrubber but im gonna guess that its in the range of 100-200 since it holds 3lbs of activated carbon. The 13gal is light tight as well as the 8gal controller so I dont have to worry about algea or anything like that. I am planning on growing 5 plants then 6 with 1 independant to be a mother plant then I can veg them and flower them when ready. I think adding another 1000w would be a nice touch I agree with ya but right now dont wanna risk overloading the breaker even though the room is on its own and doesnt share with any other rooms plus I dont think the hut can hold another without collapsing. Well being a newbie im gonna start off with schwag seeds that way if I fuck up then I wouldnt feel bad about it since I have a shitload of them. CalMag is that like a water conditioner that gets rid of chlorine if so way ahead of ya I just bought a 4oz bottle of Super Tap Water Conditioner :thumbsup:. One more thing how many hours on/off did you set your air scrubber for? Take Care
