Hi everyone,
I'm starting seeds for the first time this year and I'm wondering if it's time to transplant some of my seedlings. I have a 72 cell germination kit with several different types of plants in it. Some have germinated and are so tall they are touching the lid, and some haven't germinated yet. Should I just remove the lid until they get bigger or will that be bad for the ones that haven't germinated yet? Or should I transplant the taller ones into a larger container (I have 3" peat pots to transplant to) Or is it still too early to transplant them? I have photos attached. Thanks in advance for your help!!

Welcome to the Forum!! You don't say if you have overhead lighting and or a heat pad underneath. Been in your position every year, LOL. I would let the seedlings go a little longer as is, covered, regardless of the tall ones, remembering that one should not transplant any seedlings until there are more leaves on the stem/stalk, than just the top leaves it opened with. Keep your eyes on the tall ones, but I think they will be fine. They will just bend over and "go with the flow" while the yet-to-emerge seeds, will truck on. Note: When you do transplant seedlings, they will need overhead lighting, or they will get very spindly. Cheers!

I take the cover off when I see sprouts. But that is my way of doing plant starts.

Welcome !

I do have an overhead LED light on them and they are on a heat mat. I decided to take the lid off yesterday after scouring the internet more. They seem to be doing ok so far!! There was a very small amount of white mold in some of the cells so I thought some more air would be helpful. Hoping they are ok!
Thanks for the advice!

It's best if your lights are fairly close to the plants (a few inches above). They can be raised as the plants grow.

The white mold isn't bad. It will go away now that you have the lids off. You can use a little spritzer with water to keep the cells moist. Some of those tall seedlings should be transplanted soon and I would bury them up to just below the cotyledons or the first leaves since the stems are reaching. If not at least prop up the tray to be a couple of inches from the light as Janine mentioned.
What are they?
