Clearly, it is one of the best 400 watt bulbs on the market for vegging a plant. It is even better then the eye blue which I have. And with that wide of a spectrum, it is a great bulb to flower a plant as well. And the price and lumen maintenance can not be beat! So if you have a 400 watt hps ballast then this bulb is the ticket all the way through the first 3 weeks of flower. And if you are tight on funds then flowering with this bulb will work great as well. I have one now, and it will replace my eye blue for my next grow.
53 bucks! I'm going to buy even more before they catch on and start marketing as a grow bulb which will inturn double the price.
