My attenboroughii is over an inch now and my vent x max x talang seedlings are growing like weeds. They're in the terrarium now, but their soil is starting to break down (algae/ bacteria) so I want to repot each into a final pot... Kinda inconvienient since winter is a terrible time to harden them off in a greenhouse.

When do you usually give your seedlings their own pot? Season / size?
