Oh yeah, don't forget to let sit till room temp before opening even when coming out of fridg.
-- On the seed thing. Pollinate lower buds? Harvest the unseeded top when ripe, leaving seeded buds to ripen seeds untill they fall out when you shake over a pillow case or whatever, feeding a bloom food as soon as you harvest tops. Helps fatten up the seeds & gives them energy to store for germination & pushing up out of the soil. Many people don't think about feeding the seeds while still on the mother plant, but it helps.
