It's mold. Identifying exactly what kind is a job for a biologist specializing in molds; it's not trivial to do.
There are soil fungicides... your local garden center probably has them. Also, it's a good bet you're overwatering; most molds like very damp conditions. If you can set the pot outside in the sun for a bit, that will probably help considerably even without the fungicide.
Don't store potting soil in an airtight container because potting soil is moist. The potting soil will grow mold if you do this. Just keep it in the bag you bought it in and tie the top shut.
To prevent mold in potting soil, ensure proper drainage, avoid overwatering, and provide good air circulation. To get rid of mold, remove affected soil, let it dry out, and consider adding a layer of sand or gravel on top.
A good potting mixture for plants include three parts of leaf mold soil and one part sand to maintain porosity.
The seeds from a pepper without mold will be better for use in recipes. Seeds used for planting should also be mold-free, ensuring a healthy plant.
Bagged potting soil can go bad over time as it may lose nutrients, become compacted, or develop mold. It is recommended to use fresh potting soil for optimal plant growth.
It is best to use sterile soil in pots so that the seeds to not die from bacteria or mold. Once the seedling is established, it can be hardened off by exposing the plant to more light and perhaps cooler temperatures. Then it can go into garden soil that has bacteria and organic material.
To effectively get rid of mold on germinating seeds, you can try using a diluted hydrogen peroxide solution to gently clean the affected seeds. Ensure the seeds are not overly wet and provide good air circulation to prevent mold growth.
Throw it away!
Mold is and always has been an element of our outside and inside environment. We breathe mold spores (sort of like the seeds of mold) in the outdoors air every day. And because outdoor and indoor airs are related, we will be breathing some of the same spores indoors. The mere existence of airborne mold spores in a residence or business is not necessarily a predicament. Some people, including the very young, adults with compromised immune systems, and people with mold allergies may be more susceptible to mold growth and may experience health problems as a result.
the water and the seeds
Mold can hinder the germination process of seeds by competing for nutrients and oxygen, leading to reduced seedling growth and potential seedling death.
