Hey,
Well this guy has some interesting thoughts and info on cannabis and esp indoor lighting of UVb...but I don't trust his site will stay up so I'm gonna paste the info here so we don't loose it...
http://marijuanaoptics.fileave.com/UVB.html
More UVB Stuff
UVB emitting fluorescent tube (http://www.anapsid.org/uvtable.html) also designed for reptiles but without the infrared component.
The UVB emitting lamps (http://www.veryhighperformance.com/) from Supra used in human tanning setups appear to have a higher UVB output than the reptile type but may be difficult to implement. Click here (http://marijuanaoptics.fileave.com/supra.pdf) for the Supra order blank
The tanning fluorescent (http://www.tanninglamps4less.com/) is probably easier to implement.
F-CLEAN (http://www.agachemicals.com/content/product_detail.asp?Prod_ID=7), a film that is 90% transparent to UVB and has a 10-year-life but is not carried as inventory. The factory in Japan makes it as the order comes in. The "diffused" type is the one to use because it has a milky transparency that provides a good hide. One wonders when some entrepreneur is going to sell F-Clean online. It is priced at $1 a square foot from the factory, plus shipping and handling. Comes folded rather than rolled and it may be difficult to install on a regular greenhouse metal frame. But not so difficult on wood. It installs nicely in an aluminum window screen frame.
ACRYLITEŽOP-1 acrylic sheet (http://www.americanacrylics.com/cyroffgp.htm) has high ultra violet transmission that could be useful in scientific applications. It is sold in the USA.
ALTUGLAS UVX (NO UV FILTERING) (http://marijuanaoptics.fileave.com/zippy.pdf) acrylic sheets are sold in Europe.
The ALTUGLAS UVX (NO UV FILTERING) is also sold in the UK by this company (http://marijuanaoptics.fileave.com/zippy2.pdf).
Arc lamps (http://members.misty.com/don/shortarc.html)are a source of ultraviolet transmission that includes UVC (290 nm - 100 nm). This is interesting because "all cannabinolic compounds show an absorption maximum between 270 and 280 nm in the ultraviolet region."
John Ott (http://www.motherearthnews.com/library/1986_January_February/The_Plowboy_Interview__John_Ott) is one guy who thinks outside the current box relative to the health benefits of the UVB photon. He believes, probably with good reason, that the full spectrum is missing from our lives most of the time by design. Sunglasses and sunblock are two easy examples. But just staying indoors most of the time also deprives one of the full spectrum and its benefits. And with some folks trying to outlaw the UVB photon it may be later than we think for all of us.
