Cool, I can't wait to hear about the results.
BTW, you wouldn't happen to know if any MJ is indigenous to areas of the globe that UVC rays reach naturally?
Or maybe if any studies were ever done on MJ potency that included a grow comparison located in a part of the globe that UVC rays reach naturally?
Little attention has been paid to UVC over the years because it is filtered out by
atmosphere...
I don't believe any plants receive UVC light in the wild, the ozone blocks 100% of
it.
Although UVC lights are used in the sterilization of private ponds and pools, they are
in an enclosed case which then pumps water through the UVC container and
comes in contact with the light and is than pushed back in to the pool, also
UVC wands are used in hospitals for sterilization as well....
In may 2007, two Dutch inventors, Arne Aiking and Frank Verherijen, were granted an internation patent on a method of treating live plants and mushrooms against pathogens and pests with UV-C Light. Patent Number: WO 2007/049962 A1. In the past UV-C had only been used to sterilize things like air and water. Typically the germicidal effects of UV-C were achieved through the heuristic of "overkill." Use triple the amount of UV-C you think you need and you will definitely kill whatever it is you want to kill. The water or air still remains perfectly intact after such a sterilization. The difference, of course, with proposing to use UV-C to fight pathogens and pests on living things is that you shouldn't use any more than is necessary, otherwise there is a risk of health to the plant.
While the general method of using UV-C to kill pests and molds is now public knowledge through the World Intellectual Property Organization, the owners of this and associated intellectual property are keeping te details very close to their chests. For instance, in the aforemention patent the application of UV-C is only broadly described. "It has been found that amounts of UV-C light between .0025 and .15 J/CM2 during a period of 24 hours enables not to enduce any, or at least not to enduce plant tissue damage which has a negative effect on growth and yield of the plants while still haveing an anti-pathogenic effect.
Aiking and Verheijen's UV-C lamp would travel up and down water heating pipes in between plants in greenhouses dousing the plants either side with UV-C light.
How much light? UVC Lamp intensity between 2 and 100 watts, with an effective esposure period between one second and one minute and a proximity to the pathogen growth of between 2 and 200 cm.
Now, that is s HUGE range of variables, we can break those down.
If we take the lower end first a 2 watt UVC lamp will output approximately 1000 microwatts of energy over a square centimeter, in one second, from a distance of 2 cm.
Remember the inverse square law applies to all lighting sources. At 150 cm it's less than 1 micro watt. At 200 cm it's barely anything at all.
A 100 watt UVC lamp, on the other hand will output approximately 14,000 microwatts of energy over an area of 1 cm, in one second from a distance of 2 cm. If we leave it there for one minute (the upper limit of the duration range specified in the patent) we have to multiply that figure by 60! 840,000 Microwatts.
I guess if we're going to make any modicum of sense of thise huge range of numbers, we need some data on how much UVC light is required to effectively kill various things.
