Nasty dirty boy, look at that beautiful mess
In my opinion I’ll leave the male couple of weeks there, as he already has done his duties, would be awesome to get some of that polen for maybe future projects, also females eventually will create new pistils the next following weeks so you also can have them pollinated.
During this time I won’t recommend you to sake the plant, likely the polen will be stuck in to de sacks. A very good idea or practise (at least that is what I’m doing)atack under de male inflorescences a white paper dish , that will do most of the job while you are taking sacks out with tweezers,(hell yeah it helps a lot.)
Other way is cut downthe plant , dry it (or living, but cutting down make it easier) and give a little sake in to a zip bag and storage, the big inconvenience here is no new sacks will appear and those small ones already in the plant ,they are not going to be mature enough to get pollen from them
Edited: cause my English is not good enough, also was early in the morning
