I've been growing with cfl's and considering going MH and Hp. I found a 250 watt MH that the seller is calling aquarium lighting, he has bulbs rated 20,000K but the add doesn't mention lumens. Is this bulb good for veg grow or is it specifically for aquariums? Didn't know if Posting link is allowed so I just posted description. Any help is appreciated. thanks.

Can anyone explain the difference (other than price) in the bulb mentioned above compared to a 250 watt hortilux with the following features? Are bulbs that say aquarium lighting not usable as grow lights? richinweed can you elaborate on why not to do it?
