Thanks for your response PharmGirl.
I am just completing a grow cabinet that measures 6' tall 3' wide and 2' deep. I have divided the cabinet into two compartments separated by a full light proof shelf. The lower compartment for nursery and holding mother plants is 12" high and the full width and depth of the cabinet. I am thinking this is not tall enough, but I want to get as much room as possible in the top main compartment. This top compartment is 5' high and the full width and depth also.
I bought a Sunshine Systems 45 watt Glowpanel. Here is a link with a pic, some tech info, and a video.
