  1. hey guys just got a grow tent its 110cm x 65cm x160cm i will only be having 4 plants at one time in the space so was thinking on going for a 400w hps but the 600 is the same price would i be better off with the 600 ?
     
  2. ya the 600w is the same price to buy, but not to run. 400w is more than enough.
     
  3. You might yeild a bit more with the 600. But it is a tad more to run. 400 is enough for sure. Alot will probably say go 600 due to yeild.

    The choice is yours really.
     
  4. I am very happy with my 400w HPS works great just try not to use a eco bulb I dont think they work as good bright wise i mean...
     
  5. Its kinda like this for temps/lights on determining size Cold <-> Hot 400w-600w-800w-1000w. 400w need minimal temp control added just proper venting at the 1000w depending on room size etc you may need to add a cooling system but if its a smaller area you will start hitting the cooling system needed at the 600w+ range. So if you got the time and money go with a properly done 1000w save you time and money if you dont need something that big go with the 400w.
    Happy growing!
