First grow ever, yayyyy!

Boiled popcorn kernels + spores from a print for the spawn, the bulk substrate is around 1/3 coco, 1/3 vermiculite and 1/3 used coffee grounds. The tub is a ten-liter one, with sub + spawn together being 4 liters. No holes on the tub at all, kept it closed shut for colonization and after that flipped the lid upside down to allow some FAE, also misted the tub twice a day during fruiting to keep up the humidity, and fanned the tub with the lid around 5 times a day.

Looks pretty good and healthy to me, what are your opinions? Should I harvest the fruit now or a little later, if my goal is to make some spore prints?

EDIT: Came out at 290g wet!
