I had grown before, in college, but my first indoor grow started with a 4' floro fixture and 15 plants from some bag seed we had, just to see what I could do, 'cuz I was tired of chasing down a dealer, and inconsistent quality. It also started in the spare bedroom closet. After I hit the forums, I quickly scrounged up 4 400w MH high bay commercial lights, and adapted them to remote ballast. Then, the plants got bigger, and the grow spilled out of the closet and into the room. Before I knew what happened, I had taken over the whole room, and partitioned off a clone/veg area and a flowering area. I had also acquired 4 more 400w HPS and 8 1K lights as well, all reworked commercial lights.
