I’m able to sex a couple of the plants…
this one looks like a male…pretty sure I see a female part on this one…

Definitely that mini dehydrator is the way to go during humid weather. I put my pollen in vials in a small ball jar and put some dry rice in the ball jar and into the freezer. It was viable after maybe five months or so… also, taking a cutting now and keeping it in veg for another few weeks would probably be a good idea. It will revert to flowering very quickly when you change the light cycle back.
Plants are looking really healthy, but I would be careful giving them any more nutrients. It’s starting to show on the new growth that they have had enough for now. You’ve got some trees on your hands LOL. They’re going to be massive after the stretch!
Somehow erased what I had written up above. The top plant looks like a male and the others are female
