  1. i am about to grow some plants, and i have a question, can i use a 250 watt hps light for 2-3 plants?
     
  2. it will work fine.. just put some fan to keep the heat down as possible..latezz..
     
  3. light wattage usually isnt measured in plant numbers, but rather by sq. ft. coverage... a 250w willl cover 4 - 6 sq. ft.

    and a pair of comp fans sucing air away from the light hood will be enough ventilation in most cases...
     
  4. u can aswell grow one female plant under a 250watt, that it will give u monster buds if u grow em right.........
