I have a split entry with a half basement where the lung room is located. Across from the lung room id a guitar and recording gear office. I keep my seeds in a metal NASCAR replica that was some kind of advertising piece decades ago. I leave them in their regular packages sealed. If it’s bag seed I put them in the empty plastic things from purchased seed and label them in small plastic bags.
Temp and humidity is whatever it is. Part of the struggle is keeping the office dryer than the grow room. I’ve got SG’s and a Tele I don’t want to have to adjust truss rods and setup due to temp humidity and in the other room I want humidity.
I’m pretty casual about chasing numbers. Ironically my seeds pretty much always germinate in the dark cabinet. I lost a few free perk seeds this time after they broke soil all sourced through the same breeder. I gave up on the last one this morning. Doing a Bubba Kush photo as the problem seeds were freebees.
