  1. Hello everyone! I am planning on a new unit to set up my operations in. How big of a floor space would a 400w hps be good for as well as a 600w hps light? How many plants can each handle when growing them a few feet tall?
  2. 4by4 for 400w and/or 6by6 for 600w
  3. that puts the lumes down to like 3,400 per foot for the 4x4 400 watt... i thought you want like 5-6k lumes per foot
  4. can someone please help? :-(
  5. This shows Metal Halide, but it also applies to HPS


  6. i do not seen an image...
  7. i would suggest 4x4 area with a 600 and not 6 x 6
