They create Ozone. Ozone is SAID to be bad for all stages of our plants growth, not just bad during flower.

I'd love to hear different. However that is what I read when I looked at them.:wtf:

Vancefish Reviewed by Vancefish on . Odor Eating CFLS- My experiences and research I am starting this thread because there is just not enough information out there about its use in Cannabis cultivation. This is not like most air purifiers and uses photocatalytic reactions emulating mother nature. Uses: These lights can sterilize the air of odors, chemicals, spores, mites(very small like dust mites and their feces), bacteria, viruses, mold, fungus, and many other pathogens converting them to carbon-dioxide and water. They are just as effective as normal compact Rating: 5
