Ok I have seen a several people on here say, get the florecent lights as close as possible, even bumping or touching the plant. That is BS:cuss:!!! I came in today and saw a nice healthy leaf burned brown and curled under from a 100 watt CFL! The light had swayed slightly causing it to gently lean on one of the leafs. WTF!!! I removed the light and misted my poor scorched baby. Even the rest of the healthy leaves on the same plant were dry looking and wilted over from the bulbs heat! CFL's may run cooler, but I have learned CFL's can definitley damage a young plant first hand!

Anything you fail to control can damage a young plant.

any cfl 42watt and above will burn your plants, forget what you hear about cfls not being hot and not creating heat

Yo man i learned the hard way aswell.....i was told the SAME thing. 1-3 inches away is BS too. I have a small small space, 2x2x3 lwh. I started with 1 5000k 26w cfl. Everything was sweet til i started flowering. I had 2 20w 3000k and kept the 26w 5000k. Temp was about 82 avg. The top new shoots started growing deformed leaves split right on the vein, like a split tongue along with yellowing/browning and slit wilting. I thought it was due to a lockup of nutes cuz i had a PH prob. Fixed the PH, solving nute absorbtion prob. but leaves still grew deformed. I now have a 5000k 13w cfl and a 26w 3000k cfl. Seems like a small amount of light, but its growing a perrty green with perfectly shaped leaves and growth is now back on track. My space is tiny tho, prolly were the prob came about, not enough heat exhaust. BUT YES CFL CAN BURN

cfl's will burn the shit out of your plants you do want to get them as close as possible though...But you do have to be aware that your plants will grow quik and the lights are hot so plan on moving them on a daily bases or maybe every other day...

They get hot but the only time I've burned my plants is when I've allowed contact. It's kind of common sense that if it's too hot for you to touch it's going to burn the plants.

The tradeoff between getting light in very close and having a few burned leaf tips is very heavily in favor of the lights in close. The burned leaf tips are mostly cosmetic.

i never let the cfls touch a plant. in fact i just got done adjusting the veg closet for that reason.

dont let them touch but 3 inches away with a fan in the room moving the plants is just fine also you shouldnt mist with the lights on that will just burn more

Compact flourescents can burn your plant yes. (hence they are compact so is the heat and its distribution) 4 foot fluorescent wont burn a thang, i got four 48w regulars touching, not a sign of burning, infact its flourishing. CFL's keep away about an inch or 2

i ran 2 x 55 watt cfls on my seedlings and i initially put them around 8 to 10 inches away, this was way too far and they ended up stretchin like hell. i buried around 2 incehes of stalk and put a fan on them and dropped the light to around 2inches away. within 2 weeks they were almost perfect( apart from a lil mutant one)

OMG someone gave you the WRONG information when you were trying to learn how to grow pot from the internet?!?! are you really that surprised? stop treating information from complete strangers, most of whom probably have little to no experience growing anything, like a 12 step plan. now i'm not trying to knock the incredible resource we have here at RIU, but like ANY information about ANYthing, if you can't verify the source, you can't possibly know its credibility. regardless of where you get information you should be testing and re-testing whether or not it seems right. if you're new at this, treat the information on here like guidelines, not commandments. and when YOU make a mistake, and fry the fuck out of YOUR plant, it would better serve you to come on here and perhaps ask how you can save the plant, rather than casting blame around.
