He wasn't talking about using it with a ballast, he was talking about putting it in a normal light socket and trying to use it.i just bought a 400w MH bulb. i have a 400w ballast to support it.
what do you mean odgrop, about burning your house down? i havn't used it yet, im currently using 400w hps, gonna us the MH for vedge on my next grow.
arn't mh/hps pretty much the same apart from being red/blue spetrum, why would it being in a plug socket fuck it up?
oh right, nah i wouldn't try doing that lol.He wasn't talking about using it with a ballast, he was talking about putting it in a normal light socket and trying to use it.
