That would be tricky for me to answer in an honest way @shroomgod. I'd think the largest variable would be the size of the plant you were able to pollinate? @MadScientist I'd say of the viable seeds, probably 300-350 per plant. Each was about 2' tall, so that's relatively small really for a major seed haul. I think @Viva_Mexico harvests thousands? And @TropicalBiophile about the same? I should find some pics.
Also, I went about dusting them in two ways.
1st was in the bathroom with collected pollen on one selected plant on a few branches with a paint brush (the #1). It wasn't extremely complicated, but first covered the flowers I wanted to dust, then mist/wet/drench the others that you want to use for different pollen, uncover the dry flowers, cover the wet flowers, mate and reverse process before putting back where you're planning to flower them the remainder of the time...
2nd was by setting the females in a manner that they constantly surrounded the male so that no matter which way the wind was pushing a breeze it would get to all of them. Toward the end of the males' life, I took some branches and placed them in a solo cup with some water and rigged up an aluminum catcher to save some pollen but let it die in the pot outside. It totally exhausted itself.
So aside from the 1st pollination on the selected flowers it was left to nature to do the rest. I think indoor in a more controlled environment those variables would be more likely in your favor and you'd find results somewhere nearer @ReikoX? Outdoor there are bugs and odd things/issues that the plant also exhausts a lot of energy combatting, so it can still produce healthy offspring. That's my observation.
Make the stickers @MadScientist . Who will be making the OG ones?
