lol i agree look like something of the enterpriseyoungbud said:From what I've looked up on them it depends on the spectrum, but in general they only hit the peak spectrums for light absorbtion for both flowering and veg. Almost no heat so you can put them as close as you want to. I've read that you could even touch them to the plant and it wouldn't burn, but I wouldn't be willing to test that personally. If I could afford them I'd get them, but thats my personal preference. I think it's because they're kind of sci-fi and interesting to me more than anything else though. There are some led grows in the journals go check them out and see what you think.
