But kg1 likes the subjects so is easily sidetracked into hermies and it is a big topic for newer growers.
As far as i could get with the scientific community (not stoners or industry) was that the plant systems were too complex and relevant proteins that trigger it either too small or too elusive to find.
So a brickwall was hit and (i havent checked of late) no one knows exactly what the genetetically a herm is.
So we fall to the next level and study its characteristics to gain insight.
As far as we know there are no hermie free strains, male female auto or ruderallis ditch weedio. All strains ever bought will have a corrosponding grower reporting herms mainly.
Mjs been doing this stuff a long time in the wild and so long it decided on a genetic survival strategy to not change or cross with other plants but rather to be unchangable but love diversity within its own kind - its a hard plant to breed different leaf shape or serrations and as seen impossible to breed out the herm problem.
Another lesser study of mj in the wild shows in the bad years there were more females to males which is helpfull if you herm as you bring pollen and pistil so close even bad weather wont stop seed production.
Marijuana loves to herm and can do so with ease but we know so little else that myths such as old hermie free strains lost to commercial breeding gain support with ease and were back to broscience and gyessing.
If some one had a herm free strain it would take the market share in sales to new growers, millions in profit and fame here for about two weeks max - so if you want to believe the counter debate just forward me your herm free genetics and ill make you a millionaire seed baron god minus my twenty percent
