anyone use uvb to finish .. thoughts about it.. where to buy bulbs and fixtures light location intensity ...? i have heard it doubles thc production as the plant uses the resin to protect itself from sun stress ...

Couple things to think about:
1- UVB is harmful; don't enter the room with that light on, and if you do, be certain to use eye protection.
2- You are making more resins, so provide more available carbon for the plant to use. This is the ideal moment to start giving molasses at a couple tbsp per gallon as a safe carbon source.

I'd be carefull with a bulb like that, speically one that produces that amount of UVB.
UVB light can cause direct DNA damage. The radiation excites DNA molecules in skin cells, causing aberrant covalent bonds to form between adjacent cytosine bases, producing a dimer. When DNA polymerase comes along to replicate this strand of DNA, it reads the dimer as "AA" and not the original "CC". This causes the DNA replication mechanism to add a "TT" on the growing strand. This is a mutation, which can result in cancerous growths and is known as a "classical C-T mutation". The mutations that are caused by the direct DNA damage carry a UV signature mutation that is commonly seen in skin cancers. The mutagenicity of UV radiation can be easily hole. UVB observed in connection is one reason for concern about ozone depletion and the ozone causes some damage to collagen but at a very much slower rate than UVA.
