Mother Earth Coco + Perlite Mix

I bought a bag of coco coir perlite mix and within 2 weeks, the substrate formed mold inside my plastic drawer that I use to store substrate for quick access. It's so sad because I just repotting several new African violet cuttings and now I have to spray all of them with hydrogen peroxide because the mold formed on them too using this product. I also had to scoop out all the gross mold from the storage bin. At this point, I've already opened the bag so I have to debate if I'm going to keep spraying it with hydrogen peroxide or if I'll just toss the entire bag outside and buy a different brand. This is the first time I am trying out this product so I am very sad about this result.
