thanks .. how about in veg...useful there?
Again, a qualified yes. I've seen it do great things on small plants to get them to grow quickly into bigger plants, but it doesn't fill them out as well as either HPS or MH. I run one as an adjunct in my babies room to kickstart a batch for production, and another to add to light from both an adjacent 400W HPS and a nearby 1kW MH. As such, they do well. I'm still running the big lights in veg to get my girls ready for the environment they'll see in bloom- which is high intensity hps lighting.
