Due to space alone I may be letting them go through dormancy... I have 1 flat of seedlings in the house still and there's another um, half a flat out in the greenhouse... that half flat may be staying there because I have other seeds I want to start this winter hahaha

Maybe its the type of mold. I had the same experience with various mold on Sarracenia leucophylla seeds, but more often on seeds of the nightshade family,
f.e. Mandragora sp. It looks surprising when healthy seedlings grow out of a heap of seeds with mold.
It was never Botrytis mold.

I think the mold weakens the seed shell. Sarracenia has some hydrophobic abilities at the beginning. Maybe to let it float away. Until this layer is exhausted,water will not penetrate the shell.
I use now always living Sphagnum which is always associated with some fungus (at least in my setups). This keeps bad mold in check and softens seed shells sufficiently. That way I get molded seeds only if some are empty or dead. And that mold is restricted only to the single dead seed. The Sphagnum fungus fights it of quite satisfactorily from the healthy ones.

Yes I thought that might be the case too. So for the next batch of seeds, I did not replace the paper towel with a clean one every 2 weeks like I used to do, I just left the mold there.
 
My problem with keeping them inside is having enough light and room for the very tall ones. I have one that is 40'' tall, so it's taking a lot of room in the grow tent. Once they get to that size, it's not possible to put them on a shelve with 2 or 3 levels, it must take the whole room from the floor to the top. But I am bringing my Adrian Slack inside for sure, and it will resume growing. It's growing much better inside under LED and in the heat and humidity than outside in the greenhouse.
 
These are my champions. Sarracenia lemon legacy. Not bad, eh Sib? I still have a canoeful of seedlings that are a bit behind in growth, but I think it’s potting up time.

Well, some of Sib’s seedlings have been potted up, some will be done in a while.

I also have my fridge plants potted up, but do you see that I have a moat on the left side and a fence of cacti on the right side. Why? Well you may ask!

I caught the culprit picking out some of the freshly potted up lemon legacy plants and casually grazing on my larger Byron’s!

Last fall I received 3 crosses of Sarracenia seeds (thanks @daniella3d). This was my first time growing Sarrs. Germination was surprisingly successful resulting in very crowded pots. I read Steve Bradford's growing guide which recommends 8"-10" tall pots. I don't have tall pots less than 7" diameter- too large for my space in the interim under lights). My idea is to repot the seedlings more spaciously, and transfer these little guys outside in trays when temperatures are safe. Can I grow these in 5" tall pots safely over summer? I'm thinking of layering the bottom of the pots with clay balls or similar moist drainage, followed by an inch of chopped LFS/peat and perlite, and fill the rest with 1:1 peat/perlite.

In the fall, I will downsize to 10 or 12 Sarrs.

You can grow them in very shallow pots. This will restrict their height after a while. When you have space or when you want them to get taller, repot them in taller pots. Put them out as soon as possible (watch out for animals). It's getting late so you may have to get them used to full sun.
If the pots are drained you can use only peat/perlite. If undrained, the method you suggest is good. Keep moist. No outside dormancy for the first winter or 2 depending on size.
Also if you have extras, you can mail them as non standard mail for about $2-3.
 
Shorter pots will work fine, just don’t keep them in one inch of standing water. Let the water trays get empty between waterings, that will help stop the mosquitoes anyway.

Taller pots like 8inch can be kept in an inch or two of standing water without saturating the roots and hindering growth.

In the wild and how the taller trumpet Sarracenia prefer to grow is 8 - 12 inches above the water table, the saturation point of the soil.
