If there are no obvious signs of degredation or putrifaction, then everything that was there before will still be there now. It should be fine. Like biogold, it should keep for years unless it gets damp enough to start some significant bacterial action.

I buy the large bags of BioGold that see me for 2-3 years at a time. Stored in a cool, dark and dry place, it'll keep indefinitely without the need for hermetic seals and the like. If your Green King is in a plastic bag, it's probably best that it's not airtight. That's when you get stagnant air, condensation and localised moisture building up to start the rot.

Think of it like storing seeds. A cool, dry place in a paper bag (rather than plastic) and they're fine for years.
