I'm using 1000w so I don't think it's too much light for the plant.
But I don't know if it cost too much to use 3 lights for just 1 plant? Are those power-saving bulbs?
Well, I have to say their price is not that low. I've found a even cheaper one online shop: http://www.yescomusa.com/home.php?cat=46
What do you guys think? Thanks.
