question about my seedlings first weeks

Discussion in 'First Time Marijuana Growers' started by closetbud, Nov 22, 2002.

  1. My grow space is a wardrobe closet that measures 2ft x 2.5ft x 5ft tall. I'm running a 400w HPS. The inside of the closet is semi-glossy white melamine, so this is gonna produce a pretty intense light inside the box. Heat is being vented by an exaughst fan on top of the cabinet blowing in and another one on top blowing out. More fans can be added if needed.
    My question is this: Should I start my seedlings using the 400W HPS, or will it be too much for them? Should I use a flourescent for the first 2 or 3 weeks instead? I'd rather use the HPS the whole time, but I want what's best for my babies.
  2. You can use the HPS from germination to harvest.
    good luck
  3. you should use floresents 60-90w until they are at least 7" tall .
    keep the floresents on 24 hr/d about 4-8" from your plants
    a 400w hps will fry your seedlings
  4. if you have sufficient seperation between the plants and the light the 400 HPS will work fine.
  5. why would you want to run all that electricty when you don't have too
  6. My ittle sprout seems to be drooping, if i givit lots-o-light will it perk back up?

  7. Could be overwatering and the dampening off fungus has got it.
