So, about the Daniel's Plants 4-inch Naked Pots and mold issues—our research didn't uncover any particular complaints about mold developing on these. They’re made from natural spruce fibers, which are meant to support healthy root growth and are environmentally friendly too.

Since they're biodegradable, the roots can just grow through them directly into the soil, which is great for transplanting without shocking the plants.

A nice thing many folks have noted is that these pots help avoid problems you often get with peat, like roots getting bound up. They break down in the soil, making it easier for seedlings to grow once planted.

But do keep in mind, because they're meant to decompose, they can get pretty fragile when wet, so you’ll need to handle them gently during transplanting.

Even though mold isn't a big issue with these, it's a good idea to store them in a cool and dry spot before you use them, just in case.

If you’re keen on an eco-friendly and sustainable planting method, these might be just what you’re looking for.
