Flowering area is a box 8ft. long, 3ft. deep, and 4ft. high. Two doors on it with passive/forced intake. I grow 10-12 bushes in this box in 2-3 gallon containers. I use a 243 cfm inline fan to exhaust the box.
Veg is a 400wMH + one 4ft floro for seedling and clones.
For the growing medium I use potting mix with added perlite, bone/blood meal, some micro organic nutes. For liquid ferts I use Pure Blend for veg and flower, then flush with pure water last 10 days of flowering.
