Grow Room - The room is in a closet under a set of stairs. The grow space used was 3' x 4' with an average height of about 60". The ventilation used a passive intake along the floor at the rear of the grow room. The exhaust was a twin fan window fan. It was above the door to the room and exhaust into the garage. I also used a portable 9000BTU air conditioner and a 7" oscillating fan.
Lighting - Initially the seedlings were kept under 160W of fluoros on an 18/6 lighting scheduled. After about a week to 10 days they were switched to 24/0. A 21 days they were put under a new light I built. It was 16 32W T8 fluoros. They were very tightly packed and gave off a great amount of light. This was used throughout the remainder of the veg cycle which was 6 weeks. I then switched the plants over to 12/12 using a 400W HPS for the primary light and two 128W T8 Light Modules to throw light on the lower branches.
Grow Medium - For the seedlings I used Ferry Morse seed starter mix. It is a well balanced soil-less medium that has no added nutrients. This lets you add what ever you please. After the first transplant the plants are in a soil-less medium consisting of 3 parts ProMix to 1 part Perlite to 1 part Vermiculite.
Water and Nutes - Water used was filtered well water. It always tested slightly acid. I started off using Peter's GP fertilizer 20-20-20. It worked fine, but later I decided to go organic. During veg I switched to Alaska Fish Emulsion. During flower I used Earth Juice Bloom.
