thank you very much mrberry's for your info it has helped me alot into what strain to pick out the reason i do not want to get a carbon filter is due to i will be renting this apartment and cant fully change it inot a grow room if you know what i mean. other people have told me northern lights is my best bet to grow with least amount of odor with still keeping quality. I infact was looking at the northern light x bigbud because i would only grow to commercialize it if you know what i mean and keep some for myself i was planning on using a 400w mh for veg and 400w hps for flower i alos was planning on growing 6 plants with this setup is that light to minimal or can it work i know obviously it would work better with a stronger light but i dont wanna get obvious with the electric bill. So you think that northern light is my best bet then huh????
