White mold on the surface of the soil

Thank you very much guyz! I was a bit scared. :D I have soil from my friend. He has recommended it to me, cuz in that soil were growing champignons for couple of years.. So I’m so happy that everything is okey and I don’t have to worry about it. :) Once again, thanks a lot! And feel free to give me advices. This is my second grow, the first I failed (begginer’s mistakes) :D I’d be grateful for every help/advice. :)

Hi @StraightLine your substrate seems to me to be soaked too much and ends up creating mold. try to let the substrate almost dry between irrigations, the roots need a lot of oxygen to grow through the substrate. you should add 20% -30% perlite to that soil by doing a transplant, it will drain the water better and the roots and plants will grow better. good luck mate 🙏👍

You have a strong soil, that's perfect, and that's why everyone is behind myco products and inoculant. To make it alive.

To me it looks like nothing to worry about! If you are concerned tho you can mix that top soil and break that "mold*" apart and maybe cover the pot with clay pebbles or perlite or something so you will block the light coming to the soil. It will reduce all kind of molds and fungi and even pests. And it looks nice. ALl in all, dont worry about it and enjoy the babies grow!

Will block oxygen from getting to your roots. Scrape 1/2 inch off top layer and add fresh soil. Don't water for few days let top of soil dry out. Should be fine after that.

hello friend, in my opinion, if you are doing organic grows, you shouldn't worry about this fungus, since it's white.... and not blue or green, which would be harmful to your plants. if you have inoculated any type of mycorrhiza or trichoderma or any type of bacillus, they are now colonizing the medium, and it's very good news that you have these in your grow. in fact, I have managed to produce small mushrooms from this fungus in my organic grows! good luck with those babies🙌🙏💪
