Will a black light work

Discussion in 'Grow Room Design/Setup' started by Grassmann1, Oct 8, 2003.


  1. I've had the same issue before. I always used to have it be too hot during the day cycle and too cold at night. I combated that by running my 12/12 cycle from 7PM-AM. so the light is on durin the night because the temp outside is cooler at night so during the day, which is the plants night, it's warmer outside. I also use a little space heater in my flower tent. It's just a very small little thing I got from Walmart. It was like 15 bucks. It has a thermostat so you just play with it for a day or two to get it to turn on when it drops to like 69 degrees and then will cut back off once I'm back up to like 72, that's the key, is the built in thermostat on the heater.
     
  2. forums are to ask questions, so peace!!
    sometimes it helps to have you questions answered and not be told to search for it, if thats the case hell lets make a search forum! lol

    DierWolf.. your 100% right!!! I might be just only be 6 months into growing but from all the times going to the local growing/hydroponic store talking to their experts telling me about the importance of color spectrums to the different growing stages!!! I saw first hand when I went from 2x 125watt CFLs to a 600watt MH/HPS with the amount of new growth every day!!
     
  4. take out the black bulb bust it go to walmart and get a grow lamp  to fit it

  11. No man, If you want to use a light for growing then stick to CFL's or if you want a UV then get a UV Grow light as blacklights aren't the right spectrum. But on the bright side you can have fun with your black lights !
     
  12. check dates man

    I joined in 07, saw this exact question in the form of a new thread over and over.  Pretty sure that's why.  It is painful to read.

  16. UV Light does help kill bacteria in water so if you have any light getting into your resevoirs or have a bucket of water open for humidity this will decrease bacteria activity. About its only use in growing, everything with water should blacked out anyways.
     
  17. Using 5 26w 2700k daylight cfl's, and the 2 hanging on the right are 10.0 uvb lizard bulbs from petsmart. Lol

  18. Are your plants coated in resin?
     
  19. Only got the one on the right now, left one turned out male. There are some crystals on the leaves, pretty amazing considering they're just bag seeds..
