I've got some leftover Fafard #2 I used for potting up last year, great stuff, but the rest of the bale sat in the garage all winter (in original plastic), any moisture that was in it (or maybe it absorbed some) seems to have frozen, then defrosted as there is a big wet spot on the concrete under the bag. I'm wondering if this could be harboring any spores now, not sure it would be OK for first potting up of seedlings?

Maybe I should buy new (don't need a whole bale this year, started a lot fewer seeds than last year, can look for smaller bag)? Save this for starting greens, potting up larger plants later on or maybe just some flowers? I'm afraid of damping off my precious peppers and tomatoes.
