I *believe* (keyword believe) that if you take a cutting of one of the tops and put it in a glass of water by a window, you can collect the pollen faster
you gently shake the top over something every now and then to catch the pollen and then collect in a film canister)

I am no breeder though! hopefully someone will know.. I try to stay away from balls!

I'm pretty sure if you have tons of balls some of them must be ready
