I plan on growing in my closet 1 to 2 plants, its a 3 foot wide by 3 foot long and 8 foot tall space. What is the most cost efficient setup i can get (CFL, Fan, carbon scrub, etc.) and what kind of electric bill can i expect? Once i get it set up i plan on keeping a grow log on Grasscity, any help to get me started would be much appreciated.
