I'm looking for a good led light for my 4x4 feet growtent!
I'm wondering why the Mars Hydro is more used then the Spider Farmer - it seems the Spider Farmer uses less whatt and hase higher light efficienty?
How about the Eco Farm or King Led?
I've used all sorts of grow lights.. And Spider Farmer is absolutely overpriced. ECO-Farm is good I have 2 lights I purchased from them. Parfactworks is good too.. I'm growing with 2 parfactworks right now and getting great results. Price is fantastic too. Much cheaper the spider farmer.
Check out Invisible sun and Migro aray, there the only ones I've used. Pulled 4.1 oz from a purple lemonade under a ish150 pro (invisible sun) Never used the ones you list but there's plenty out there.
