UVB Light..Anyone got experience?

hey fellow growers...

Has anybody got any experience in using UV lights, well mainly UVB lights in flowering?
I do know that the UVB light helps the production of THC but i want to know is what wattage to use, how long you should use it for as in the whole 12hours of the 12/12 or not and also what proximity.

Not sure i will use it for my current grow but maybe my next.

Thanks in advance.

if you choose to use a UV light like one used for sun tanning, then only use it three times a day for ten minute increments, for a total of 30 minutes a day. First find out what the spectral peak is, (UV-B has a wide range compared to UV-BL or UV-BLB) and make sure it does not go into the UV-A range, or you will kill your plants a little each day.

I was kinda looking at the UV-CFL's....the ones they use for nail varnish shit..Any idea on these?????
