Okay so me and my friend FOUND a 400w HPS system in this guys trash.... of course we took it, and it WORKS! :] now i have a few questions, as of now we have 4 (seed bank) seeds Can you VEG on a HPS light? (were vegging for a month) Is 400w HPS, and 104 CFL (Flower) enough to run about 4 plants? Were kind of on a tight budget so were going to build a lockable wood grow box (Mylar on the inside of course), My friend just wants to run the light in his closet with pretty much 100% light leaks lol, so should we build our grow box? Thanks!
