Root Naturally 42mm Peat Pellets - 100 Count

Is there an expiration date for the peat pellets? or can i use them over several years?

Can I transplant seedlings without cutting the net around the pellet? Otherwise, how do roots get thru netting?

Do I still need a pot or can I just start these in a tray?

the product says it has 25% coir fibers. does it say that on the package? it should raise the ph if it does have it.
