I’ve noticed that some people store kelp fertilizers in their refrigerators. Is this the best way to store it to prolong its effectiveness? How about Quantum Total? I just received new containers of both, so I want to keep them useful for as long as possible.

Thanks

Certainly, refrigeration will prolong them , but the current Kelpak lot in the US has an expiration of 11/22/24, and even the grower with a small collection will probably use a liter by then.

Quantum has a production date on the label. Unopened, it has a 2-year shelf life at room temperature; 1 year after opening.
