I'm growing some superhots indoors with just window light and have noticed extremely low pollen production for chinense varieties. The annum however rain pollen...
What I've had to do is pick a few flowers off the desired plant and crush the stamen with the back of my thumbnail to release the tiny bit of pollen and then use that to pollenate the flowers if I want pure seed.
If you want pods and don't care about the seed purity, then just collect a ton of annum pollen and pollenate your superhots.
