Yes Ive looked at those options but I'm doing a stealth grow only 1 or two plants. The smallest hps grow light is 150. Thanks for your input but nobody has answered my question. 70 hps bulb is like 15$ and light clamp is like 15$.
So I went to lowes and they have a buch of hps bulbs like 35 50 70 100 watts and up. And some have a medium base and others have a mogul base. Can I buy one of those Aluminum type light clamps and put a 70 watt hps light bulb in? Or does it need a ballast or something?
