Is there a particular explanation as to why a 400 watt HPS ballast would cost about $40 from 1000 bulbs dot com, and the bulb itself like seven bucks, when a kit/ballast from a place like HTGS would cost more than $150?
Horticultural ability?
Inferior materials?
Any good reason to stay away from such an attractive price?
