how many plants can you do per 1000w mh/hps??

  1. See title haha. Im tryin to figure out how many lights I need to buy
     
  2. depends on grow style and available space. In my situation, under my 1kw hps I'm doing 6 in the 4x8' tent but next time around will be 5 (hopefully) under the same light but 1/2 the space.

    Hope it helps.
     


  3. If you're looking at buying more than 1 1000w light, you should decide how many based on how many you can plug in before the breakers flip.

    You don't necessarily decide how much light by number of plants either.

    How big is your grow space?
     
  4. I have 4-1000 watt lights in roughly a 12' x 12' grow area (in each of 2 rooms) and grow 20 plants under them. I average 5 lbs per crop with a 6 week strain that veg'd for roughly 2.5 weeks in a 3rd room (after clones showed roots) before moving them to the main rooms.
    A rule of thumb I use for 1000 watt lights is to have the plants no more than 4 feet from any light (or 3 feet for 600 watt lights)
