I really like this light for my 2x4. It has given me pretty dense colas at the canopy but I suspect the light penetration may not be the best. Hard to judge if it's the light or my inexperience at training the plants. Light produces very little heat underneath which probably saved my summer run. Winter may be a different story though. For 3 plants I think it did very well and if it's one of the few lights in your price range I don't think you'll come away disappointed.
