you can try and pick off all the pollen sacks. but if you miss ONE you'll get seeds. it's risky. If you could make another chamber inwhich there is no gass exchange between them you could make it happen.

but if you are picking the balls off every day. you shouldn't have a problem And if one gets loose seeds arn't that bad.

i plant to pollenate a few of me girls this time around so i can get a bunch of back up seeds
