So, my buddy came over and told me that it was good to put the harvested buds in the sunlight to dry them. He said that it helps. But I persistantly told him that was a bad idea and it will degrade THC levels. Was I right to say this or what is the science behind this idea? I just want to give the right information out there so I can stop this rumor and hopefully I didn't start another marijuana cultivation trick rumor....there are so many stupid lil tricks that people think work and just don't even work or the method will show negative results. People are encourgable.
"Incorrigible". (Also see "ironic').
Anyway, your friend isn't totally insane; sun-curing bud actually is one historical way to do it. But usually the buds are WRAPPED UP first, so that they aren't exposed to direct sunlight, but rather just heat from the sun.
In any case, even though you "can" cure buds this way, that doesn't make it the 'best' way, and I think you are dead on here.
A few seconds of light won't ruin your buds, but to the extent possible, you want to avoid exposure to sunlight and high temperatures, because both will degrade THC. Even if they do/did dry bud this way in the mountains of Columbia, for example, I don't see a good reason why you should want to do it at home!
