At the moment shes got her own light. I run a 600w hps in my regular grow room, which is full of shorter indicas and sativa/indica hybrids. Most of them will hit 4 - 5 ft max. Shes sitting under her own 250w hps at the moment.
This bitch however, will stretch like crazy as soon as flower kicks in. I started flower at about 1.5 feet and she stretched to.... well... 6 and a half feet today. Full flower goes on for about 10-12 weeks. Im hoping for a christmas harvest around 4-8 ounces....
edit: I figure I should also mention I use organics. Some of the most idiot proof fertz on the planet, and will leave you with some of the tastiest buds around
