We got em in a Titan Control 12 site Grow n Flow system, 55 gallon res. Under a Maverick Sun Bigfoot and Hydrofarm Radiant 8 both with Hortilux 1000 watt bulbs and magnetic ballasts (plan to upgrade to 2 Bigfoots and digital ballasts as soon as funds are available). Using Grow, Micro, Bloom, B-52, Bud Candy, Big Bud, and Bug Ignitor for now (any recommendations on changes or additives are welcome). Thanks for all the input and support will keep you updated.
