I've never had much luck with seeds in the past, but I'm about to try again, so your success is very encouraging! I'll be interested to see how your little guys progress.

It would be nice if you said what the seedlings were.

Not sure they came in a mix pack

Hello Spike, sorry if you think we've been giving you a hard time lately, but stick with us, read the replies you get carefully, take note of what is written and you and your plants will be fine! Most of us here have been teenagers ourselves (some longer ago than others, lol, so we do know how it is! It is encouraging to see youngsters here.

OK, you say they were seeds from a 'mixed pack', but a mixed pack of what? I suspect cacti as you said you were expecting a batch. Are they cacti, aloes, sempervivums, etc etc etc? The more info we get, the more advice we can give you.
Whatever they are, don't let those little ones get long and thin aka 'etiolated' through lack of light...keep them in a bright spot and remove the plastic cover gradually. Don't drown them, a good spray should be good enough.
