Do Cfls run cooler?

  1. Alright so the actual question is do CFLs burn hotter than normal household bulbs.

    Why I ask is because I just ordered my seeds and they will be arriving two weeks before I move into my apartment so I set up your standard cheap closet grow, it's just a cardboard box with some cups and a fan blowing on it and a 240CFM blowing the air out the top. I can supply pics if needed. Well I am waiting to get my CFLs in the mail so I did a dry run with two 100W household bulbs and they were running the box a little hotter than I would have liked and the CFL bulbs I got were 60W straight up, 250W equivalent. I tried googling it but didn't get very far. So will the bulbs be cooler or more hot? I can get the temp down by just keeping them in the closet, but there is other stuff in there and I don't want the person I am living with to get upset, they know I grow, but they wouldn't want it all open around their stuff.
  2. You mean regular incandescent vs. CFLs?

  3. Yes. You also can't grow with incandescent bulbs.
  4. I know you can't grow with them, I was just doing a Mock test run to make sure the air movement was on point before putting the new seeds in there when I get them. I was just to impatient to wait for the new bulbs
  5. Watt per watt they produce far less heat - incandesecent bulbs produce light by getting hot - CFLs dont produce light this way - they excite a gas - Fluorine i believe???
  6. Very much but I ran 6 100w eq using spreaders to fit 2 mini cfl into one reflector. Also, you MUST order a few Ona jars and open them in grow area for smell since the entire grow area will smell like weed! Had fan running allowing 2" from leaves - though a few tip got brown. I swear by the cfl for apt closet grow. Easy on elect and heat!
    My 2 using cfl at day 30 in pic. Just began flower. Will post bud pics when ready.
    I'd send you my 6500k minis if I wasn't going to try a DNAs 60 day wonder. One of fastest from germ to harvest to date, hence 60 day.

  7. wow those are some nice plants Jack straw - respect mate
  8. Have you looked into odor controll especialy in flowering? Something you might want to look into since you have a roomate. Some plants can really stink in flowering.
  9. Sorry if I did imply well enough that they were only going to be in that closet for two weeks...
  10. Ah ok. 250 watt equivalent CFL`s will produce a decent amount of heat. I use T5`s for seedlings, clones and short term veg growth then switch over to a 1k MH for more veg growth if needed then HPS for flowering. How many 250 watt CFL`s are you going to be running?
