Good evening all...(depending where on the globe you are)...I'm a fairly new grower. Ive been playing around with it for awhile, and recently decided to get serious about making it through a full grow. Ive tried several times and was never completely satisfied with the end result. My room is a sealed 10 by 6 closet...ventilated with a 4" inline fan with carbon filter. (moved from a small growbox I used to use). I have 2 MARSHYDRO 300W LED LIGHTS. I recently got some really good beans from "a site" and I want to maximize my yield potential. I am in the process of buying 2 600w led lights to add to what I have, so that way I can grow 6-8 plants a time. Am I already on the wrong path? Soil medium in 10gal grow bags. ANY advice would be helpful. Thanks in advance.
