UVB reptile lighting

[ak40kush]

I was curious about the effectiveness of these lights in a grow. they are made to replicate the suns light. My friend has them for the many many reptiles he has at his place. apparently they are cheap,last a while, and don't use as much power as expected.

If anyone can give me some information on these lights in a grow let me know please, i would appreciate it.

the ones that i like are these http://www.thatpetplace.com/pet/group/3450/product.web

and they are pretty cheap also,but you have to use them properly and for the right kind of weed,they work great for indicas such as afghan kush,or hindu kush
and they might even work for some sativa's like columbian red and panama red(aka puta roja)because those areas have high concentrations of uvb and the landraces that grow there have evolved in order to cope with it,and they do so by creating extra resin heads,but it wont always work for EVERY strain,but i COULD see every strain benefiting from uvb light as a whole

A little about UVB lighting:

A researcher conducted a controlled experiment in a greenhouse. He lit a group of high potency plants similarly except with the addition of UVB light to some groups. He found that the percentage of THC increased in a direct ratio with the increase in UVB light. This research confirms the adage that high altitude plants are more potent than those grown at low altitudes.

If you look at old-world land races of cannabis, plants that have become adapted to the climate and latitude, the ratio of THC to CBD starts at 100 : 1 at the equator. At the 30th parallel (The Hindu-Kush Valley) the plants have a ratio of 50 : 50. At the 45th parallel the ratio is near 1 : 100. This corresponds roughly with the amount of UVB light received at these latitudes. There is much more UVB at the equator than the 45th parallel.

thanks for that bricktop,i was trying to explain the same thing,also i was wondering if i could ask you a question about landraces in particular,lets say i move to the dominican republic which is right on the equator,which land race would you recommend?

Do you have a source for this information, I would love to read up on it.

I found something... kinda interesting, really outdated but the only experiment in the field.
