Hey everyone this is my second grow and ive decided I would use the scrog method in soil. I'm using Fox farm Nutrients and dirt. I have a 250w mh/hps switchable ballast The box its in is Depth- 2.5 ft, Width- 2.5 ft, height- 4ft. As well I have a 4 inch exhaust fan pulling hot air out and a fan blowing cool air in. Here's what the current setup looks like.
