I always chit mine in margarine tubs in the hot press so you know if they’re viable in a couple of days, it also eliminates any chance of dodgy compost causing rotting. With the move to peat free there seems to be a lot of pretty rough stuff around. Old yellow seed only got 1 from 4, Lidl round ones almost 100%, T&M climbing ones 2 from 3. Plenty of time to sow more.
