well my plants are hermies.for my first indoor grow i got seeds.when are the seeds ready.do they get hard while they are on the plant or when its drying.today will be day 40 of flowering.lots of red hairs and crystals and seeds.when i squeeze the seeds they are still moist.how much longer till they are ready to get the hell out of my flower room

Usually they change from green to brown and finally dark-brown or black in corlor when mature. Also seeds should be frozen or dried and cured before germination.
It is best to keep seeds on buds until they are fully mature,dark-brown or black. I hope someone would give you some details on how to dry and cure your seeds properly.
