So after thinking I was going to do CFL's for my first grow, i was looking in the light department of my local lowe's when i saw Sylvania brand HPS/MH bulbs ranging from 100-400w. The ones that were 100w and under had a medium sized base (Fits normal light fixtures), but when i took it home and put it in a normal light fixture it did not work ):. Do i still need a ballast for the bulb if its as low as 100w!?
E: Are there any DIY ways to ghetto rig this if a ballast is needed?!
