HPS all the way through works good if you've got the right bulb. The better ones have expanded blue light spectrums for better veg growth. That's why they cost more. But they start with 400 watt and go up. Most of the ones you find for the smaller fixtures haven't been designed specifically for growing weed like the high end ones. Not to say you can't grow with a 150 watt HPS, just don't expect the same kind of results a better bulb would give.
