During my reading yesterday I found that UVB increases resin drastically, and the amount of UVB available is in direct relation to the amount of thc produced. This means that plants who get more light energy can produce more thc in the end, but it also means that all artificial lights and any HID that passes through glass will produce buds of an quote "standardized (limited) potency."


I just thought that I would throw in what Ed Rosenthal states in his new edition of the growers guide concerning UVB,

It seems you are indeed on to something here..

UVB LIGHT

Ultra-violet B light is a spectrum of light that is invisible to us but is visible to insects and some other organisms. In humans it causes suntan and sunburn and is implicated in the formation of eye cataracts. It is the light emitted by tanning bulbs.

UVB light also affects marijuana potency. The potency of high quality marijuana increases in direct ratio to the amount of UVB light it receives. This is very significant. In California, where the medical dispensaries operate in an unrestricted market; many dispensaries reject fall harvested outdoor material as inferior. They have found it lacks the potency of indoor crops and is a harsh smoke. However, when they were presented with marijuana grown outdoors but forced to ripen August 10, they accepted it as if it were indoor because of its high potency and lack of harshness. I think the harshness results from cool nights.

Indoors, under fluorescent and HPS lamps, gardens receive little UV-B light. Metal halides emit a bit more. However, there are ways of supplying your garden with UV-B light. Tanning lamps work, that is, lamps that tan people, because of the UV-B light they emit. Using tanning lamps will increase the THC content of the crop. Reptiles and lizards require the spectrum to stay healthy. So the spectrum usually comprises about 10 percent of their output. If you want to try tanning lamps they are available on the Internet. Use between 5-10 percent of your total wattage to these lamps. For a 1000-watt garden use 100 watts of special lighting.

Adding UV-B light to your garden will enhance your marijuana naturally, without “special formulas” and chemicals.


I found this info HERE as the book isn't out yet.

Just thinking that it might be a good idea to try, especially with those like McOne actually doing experiments with it. At least when I try it, I have an idea thanks to this thread as to how much UVB to give them...:)

its for the medicinal and spiritual value..... I prefer high strength cannabis so little is needed.


Amen brother.

Great info. I am growing in a greenhouse in Alaska. I think I'll get some UVB light to supplement the daylight this fall.



Thanks for the insight.
