Yesterday evening I planted a bunch of succulents (at least, I'm assuming they're succulents—I ordered from four eBay sellers, one of whom was actually reputable). Anyway, one of my pots contains only relatively large blackish seeds.

The above photo is an overexposed comparison of my pointer finger and the seeds. I have really small hands so I'm not sure how helpful this photo is

Yesterday they looked totally normal. 16 hours later, I checked on them and saw that all of the black seeds had turned huge and white. They're maybe three times as big as the normal ones. I'd take a comparison photo but I don't want to disturb the seeds in case this is normal.

If they even are succulent seeds, is this normal? And what are they?

You can also see bluish stuff on the white seeds, so I'm wondering if maybe penicillium mold had a wild party in there while I was sleeping. But isn't it normally fuzzy white mold that grows on seeds?

The soil is sterilized. It's moist but there's good drainage, and the pot is covered in plastic for humidity retention. It's in a stable 70° F environment in direct sunlight for the first half of the day.

Welcome!

Your combination of wet soil, plastic wrap and full sun steamed your seeds. Try again with damp soil, an air vent in your plastic and no sun. Cover them with a very thin layer of sand or potting mix.

I don't know what your seeds are either. When they germinate, please post photos so we can see too. Smiling

I would not necessarily make holes in the plastic, move the pot out of the sun, or allow the soil to dry out at this time.

When I plant cactus seeds, I normally cover the pot with clear plastic until they germinate, and then remove the lid once they are sufficiently big and succulent to hold some water and tolerate the soil drying out. When the seeds are big (looks like yours are), you don't need to worry so much about this, but it's a good general rule. My goal is to have the soil 100% saturated until germination. You have to try to sterilize the soil if this will take more than a few days.

Indoor sun is not direct because regular window glass blocks most of the harmful UV rays. It is much kinder on plants than outdoor sun. Ideally I try for hours of daily sun indoors when I plant seeds. I'm not sure it's required or helpful for the actual germination, but strong light is good for the growth of the young succulent seedlings.

Welcome!

Some cactus seeds and seedlings here on our kitchen windowsill facing SW (afternoon sun). The seeds in the first 3 pots have germinated but the baby plants are too small to lift the lid yet. The seeds in the fourth pot have not yet germinated.
