Absolutely.
When you have regular seeds, males produce pollen first, then the females start flowering a couple weeks after.
With CS, pollen still comes first. Collect your pollen, keep it in a baggie or little jar with a bit of rice (to keep it dry). When your flower starts flowering, go for the money shot. But keep it going for a while. The buds pollinated first should ripen in time.
I do it like that and end up with nice ripe seeds, but many unripened. If you don’t want a pain in the ass sorting what could be lots of seeds, pollinate, then stop. This way you won’t have to cull so many unripened seeds.
But I’m a relative newbie so… maybe someone has a better way.
