Are these bags of medium still good?

They’re been sitting in my garage for months. One bag is open and I was wondering if bugs may be in there or the nutes have gone bad in the happy frog.
Any thoughts would be nice

Fill your pots. Plant your plants. And grow.

I'd use them in a heartbeat.

They were nice and fresh looking

Good to go, 3 year old Cotton Burr Compost got me through 2020
