I've currently got 3 arilbred crosses sharing the same large peatpot (currently under growlights) and I was wondering when I should start hardening them off outdoors?

The area of California I live in gets the occassional rogue frost through April. I had originally planned on starting to move them outside at the end of April/early May, but the problem is one of the seedlings grew faster than expected. It's at around 4-5 inches and is just getting its 3rd leaf. The 2nd biggest seedling is right behind at 3ish inches and 2 leaves, and the 3rd seedling is just getting started.

Should I stick to my original plan or try and transplant the largest one?

This is my first time growing Irises from seed, so I'm trying hard not to screw it up.

I start taking them out in the sunlight as soon as the weather is warm enough, just starting for an hour or two at first, and increasing it until they are out full time. The more they are hardened off the better it will be when transplanting them.

Will do! Thank you!
