Maximum Area for a 400W HPS Light

[Backpacker420]

I decided to get a 600W digital one and my grow box is 5x5 hopefuly my seeds will start germinating soon and I can get them under some lights.

Smart choice, where did you get it from?

Remember that a digital ballast runs cooler and is also more efficient!

Backpacker420 Reviewed by Backpacker420 on 02-15-2008. Maximum Area for a 400W HPS Light I plan on having about 20 plants flowering at all times in a SOG style perpetual harvest with a 400W HPS. What would be an ideal size enclosure for this grow light, space is not an issue i just need the best dimensions for this size light and plants. I was thinking a 4x4 square flower cab with another about the same dimensions for mother/clone vegging with just cfl's. Rating: 5
