@drdawg I was going to mount these above a metal four shelf unit I have in my small 6 x8 GH. The reviews said it runs cool enough to put it within 6-8 inches of the plants. Do you think it is powerful enough to provide light for the whole GH if I ceiling mount? It is only 2' x 12 inches deep, four bulbs,x 24 watts each, and total 8000 lumens. Maybe it's just big enough for that one side of the GH?
Clearly I don't know what I'm doing here ...again my inexperience shines thru. haha.
UPDATE. googling and a garden shop that sells similar had a chart and for the 2 foot long 4 bulb it said to place it 6 inches to 2 feet from the plant. So I guess that answers the question.
