I started several seeds in a Jiffy's seed starter kit. Many of them came up just fine, and I removed them from the kit so they could get air. I have to keep them inside, however, due to the fact that I've lost many plants to snails and other pests if I leave them outside on the screened-in patio. They are on one of those TV dinner tray tables right next to my window in my room. The peat pellets have grown this white mold or fungus (?) on top. Google has said it's harmless, so I just kept on as usual. Then it started turning this light blueish color. Google still says not to worry, but that there probably isn't enough air circulation. I don't have a fan, and even if I open the window, there is no wind at all anyway.

My questions are; Is the white/blue mold really of no concern? And, is there some other way to get these plants some wind, or am I mistaking 'air flow' for 'wind'? I open the window for the majority of the days, just in case some breeze comes through, but so far it's been in vain.

I have basil, tomatoes, peppers, thyme, rosemary, several different flowers, cilantro, lettuce, sage, onion, moonflower.

The basil is all in a pot and only recently has starting growing mold. The moonflower, thyme, cilantro, and rosemary have no mold. Everything else, which are in peat pellets from the Jiffy's kit are all completely molded over, except a few, which appear perfect.

I live in Central Florida, if that matters/helps.

Welcome to All Things Plants, @Oh !

My thought would be that everything is just too wet... I'd try to hold off on watering and let things dry out (and buying a cheap table fan could help, as well -- not just with the mold problem, but the plants will grow stronger if there is air moving them around a bit).

You could also sprinkle the surface with cinnamon.

I despise peat pots or any of the little seed starting things that have mesh. Peat pots can wick and I have found they are either too wet or too dry. The mesh pots will restrain root growth. When I tried them, a planted out seedling would keel over and upon inspection roots never made it out of the mesh.

For the mold - too wet. Spray lightly with a solution of 10 % bleach and water. That should kill the mold.

You could try a small fan. I run one constantly (on a timer) on my seed trays.
