Fridge grow 250 hps or 400 hps ?

  1. Looking to fit a new grow box /fridge . I'm thinking of modifying the thermostat to keep it at 75 with fresh air coming in .

    I'm going from cfls to hps . And 250 hps is good for 3x3 right ? So is the 400 hps way overkill ? They are almost the same price to buy but not to run .


    Please help !
     
  2. sombody , anybody ?:wave:
     
  3. if you can make absolutely sure you can keep it from getting too hot, by all means get the 400 watt hps. that way even on your next grow, if you decide to have a bigger space and more plants you can reuse the 400 watt without having to buy any additional hps systems. figure out a way to keep it from getting hot...then buy the 400 watt hps.

    ...i posted a thread asking if theres such thing as too much light, because i have 10,667 lumens per sq. ft. and every response i got was that as long as its not too hot, and the plants dont get heat stress...theres no such thing as too much light.
