i personally recommend these floros
http://www.wormsway.com/detail.aspx?...ku=SSG104&AC=0 they use tt-105 bulbs.. super high output.. very very low heat output... you can also switch between grow or bloom bulbs to cover all phases of growth.. way more pricey than standard floros... or even HID lights.. but will keep up with most HID grows... check out my youtube video (one of the links in my signature) to look at the girls i just harvested....
