Storing Media Outdoors

[MateoinLosAngeles]

I know some growers in this forum have some outdoor space, like a patio or balcony, but no garage.

Have you ever found any inconvenience in storing your media (bark, sphagnum, etc.) outdoors? Especially using the stuff you stored outside on your indoor plants?

I buy in bulk and keep it all indoors but wanted to tidy up my place and take advantage of my balcony. I store some "potting soil" (milled coco husk mixed with perlite, no peat) outside, and when I went to repot some aroids, I was surprised to find the entire surface covered in teeny tiny spider eggs. It's a bit gross but not a deal breaker for me, as spiders predate on many pests and are not dangerous to the plants. I even used the potting soil indoors and don't have a spider infestation, if I ever see a spider, I let it be. I imagine they were attracted to the moisture and found a little crack to get in and build their nest.

My main concern is for those things that I can't see: mites, snails, slugs, and any other critter that might place their eggs away from the plant. So before I bring my supplies outdoors, especially since I will be using them indoor/outdoor, I wanted to see if there are some rules to follow that the forum could enlighten me about?

Thanks!
