Follow up question, At what point do you want to harvest for seeds? Is there a window when the seeds are ready or just the more mature the better?
Thanks for the info in trying to pollenate a single flower btw, I appreciate that.
I'm working through a seed run in my journal if you want to see how a rookie does it - link in my sig
Use a separate room / area / gardening outfit if possible.
Separate the best looking boy - you only need one - into the separate enclosure. Feed him just like the girls.
Collect his pollen as he begins flowering - I jacked this up and had moisture issues. Don't rush to put the girl in - the boy will grow a BIG main flower and cause a storm. Get another sock for your carbon filter and expect to clean every few days - more in late flower.
Grow the girls as normal - take the best one (I'm doing two)
As the boy begins to spew in earnest - put the girl in.
I banged the main flower on every inch of the female, then hand applied appx 1/4 tsp to each flower site.
Repeat for 4 days or until pistils recede.
