What's all the misinformation running rampid here?
1.) Males DO produce THC. Just not nearly as much as female buds (which are seed pods, clustered).
2.) You CAN stress a male to turn female just like you can stress a female to become male. It will produce just like any other hermie would. If left to flower long enough, it should produce stalked trichomes just as any other female would. Potency may be lower than true virgin female.
3.) I've never tried it, but I bed dollar to doughnuts that the bubble hash you're talking about with mostly male pollen sacs is... drum-roll please... POLLEN!!! It may still give you a buzz due to the fact that within the male flower sacs is where the males have the most amount of trichome heads. They are not raised like the females are. And it's not NEARLY as much as female buds; however it'll still give you a buzz if you smoke enough of it. You can see them youself with a scope if you open one up. You'll see pollen mixed with the trichome heads. The heads will be slightly larger than the pollen.
4.) As stated before; because of the low trichomes to plant material ratio in males, they are very rarely kept or harvested for anything other than seed production. Their pollen is harvested, and the plant destroyed. The pollen is then used to fertilize female plants by brushing pollen against the pistols (the white hairs). Once done her pistol will turn a darker color and she will produce a seed in her seed pod... or singular bud.
