  1. i have a 2.5x2.5 space.
    i have a MH 400 watt with a wing reflector, switching to 400watt HPS for flower.
    all will be 3 gallon smart pots.
    i'm currently growing 2 autoflowers, but next grow id like to go for 4 or maybe 6 if feasible.
    how many plants would my light efficiently support?
     
  2. Probably two
     
    • Agree Agree x 1
  3. a 400 watt HPS system with a reflector can only support TWO small autoflowers? uh, really?
     
    • Winner Winner x 1
  4. Depends on how small they are but yeah. I currently use a 350w full spectrum for each plant I grow. It's all about light coverage and the more plants you add the less light each gets.

  6. you have a 400 watt hps?
     
  7. what do you think of 5 plants under a 400 watt hps system with wingreflector. 1 in middle and 4 around it, with 4 cfl lamps around the outside?
     
  8. Honestly 2 is going to be cramped but it should be fine if you put them in opposite corners. It's a tiny tent there isn't much you can do.
     
  9. My first grow I flowered an amnesia strain under my 315 cmh. I lst her, topped her, showed her all the love. She gave me six and half ounces of some great bud.

    My next grow I have random Cali med grade seeds unknown. (One turned out to be sour diesel). I end up flower three under my cmh 315...

    Can you guess the yield? It was just over 6 ounce with a lot of popcorn nugs due to them not getting proper lighting. I would say two is good of you plan to scrog. That will allow you to set the growing space . An 400 HP's might be good for an 3*3 scrog but even that might be to big for the light.


    You should upgrade to an 600 or higher and use the 400 for an veg light
