Hey @hollyho . If you adhere to strick protocol, it is possible to isolate individual males pollen, in the same growing space. It’s a real pain in the ass but here’s how I do it. I kind of treat pollen as if it where a mold spore that will ruin my room if not contained.
There are easier ways to pollinate plants for sure, but this satisfies my need to account for the origins of all(mostly😁) pollen as I keep clones of males till I find out which ones make the nicest progeny.
