Just a simple 2 x 6 and 2 x 4 wood frame, Enclosed in Mylar reflective material (Facing in of course), open top other than the light hanging down, hole in side for 9"-1' fan. Box intended only for vegetative growth, plants only grown for 1, maximum 2 months at a time Any suggestions?
First read a book on th' subject, then ask a question, from that info a reply would be as big as a book. but of your asking only about th' lite I use HPS for th' whole grow W/ a little help from a flour. th' first couple o' weeks.
