How long to keep seedlings in Humicontainer?

As my topic suggests - can anyone assist with how long i should be keeping my seedlings in the Humicontainer? :slight_smile:

Stage of growth" Germination stage 1-2 weeks, then Seedling Stage - take seedling out soon as possible, once you see 1st set of leaves “true” leaves , Light you are using ?

thanks for the info… am using 20W aqua-glo. Have never grown from seed before and appreciate any advice. :slight_smile:
