use the cfl's for the seedlings...

use the 400w for the veg/flower...Keep a fan blowing across the tops of your plants at all times when the lights are on and you wil be able to get lamp pretty close...I get my 400w MH sunmaster warm deluxe as close as 12-16 inches with just a small fan.

Hope this helps.
latewood Reviewed by latewood on . Lighting Stages Hey everyone I have a few questions on lighting for you guys, this is what we have to work with. Space: 2' wide, 2' deep, 4' high (can expand later on if needed) Lighting: CFL 20(75)watt Soft White, CFL 26(100)watt Soft White CFL 26(100)watt Warm White, CFL 26(100)watt warm white and then finally this 400 watt HPS system https://www.futuregarden.com/cgi-bin/shop/30-3115.html Now I know with the CFL lighting it is best to keep them 1" - 3" from the top of the plant but with the HPS Rating: 5
