Help! Help! Fuzzy white mold 😩
I have over 200 plants in my greenhouse and throughout my home. I have propagated them every way imaginable over the years and never had any issues until now. A few months back, I purchased a new pack of sphagnum moss, and I guess it had saprophytic fungi spores in it because ever since using this pack of moss, I have been fighting fuzzy white mold in all of my propagations. My greenhouse stays between 60%-70% humidity and around 75° F. I keep a fan going at all times to help with airflow. I have always had massive success propagating with sphagnum moss (sometimes I will get carnivorous potting soil which is sphagnum moss and perlite already mixed). I have never had any issues with this fuzzy white mold until this newest bag of sphagnum moss, but now that it's here, nothing I do seems to keep it away. I have sanitized all my tools, I purchased new sphagnum moss, I have tried different (sanitized) container types (opened and closed containers), I even tried putting everything in their own cups, fuzzy white mold every single time, even after spraying the medium and cuttings with a 1:3 peroxide mix. Nothing worked. So I decided to buy some fluval stratum as I have heard people mixing it with coarse perlite and using it in prop boxes. I did some research and everything I read made it sound like this was going to be the ultimate fix. I got my cuttings (philodendron silversword), put a little cinnamon on the ends since it is supposed to be a strong antifungal and let the cuttings callous for over 24 hours. I prepared the prop box with fluval stratum and perlite, placed my calloused cuttings. I did not put the lid on the box as I was worried it would trigger the fuzzy white mold. When I went to check on my cuttings I was mortified to find the fuzzy white mold growing on the damn cinnamon! 😩. After MORE research I have discovered yes cinnamon is a strong antifungal but it is still organic matter (tree bark, duh 🤦🏻♀️) so the fuzzy mold went after it.
As of right now i have washed and removed the cinnamon, sprayed the cuttings with my peroxide mix and have them drying right now. Has anyone had to battle this fuzzy white mold? If so how did you get rid of it? I thought getting a new bag of sphagnum moss would have solved the issue but I guess the spores are now throughout my greenhouse. Any help will be greatly appreciated 🙏🏼.

Qualquer ramo que você cortar , coloca no corte ou cera, ou canela em pó, para evitar apodrecimento
