Do your nutrients expire?

When stored properly, the nutrients we carry will not expire. Nutrients should be stored in a dark, cool, dry place in an airtight container (the bags they come in will work well) and they will last indefinitely.

Over time, the magnesium sulfate can clump together, but this can just be broken up before use – it does not impact the quality of the nutrients.

The calcium nitrate we carry is exceptionally water-soluble. This ensures it dissolves fully in your system and all the nutrients are available to your plants. This also means that it will liquefy when exposed to humidity in the air and become unusable, so it is especially important to ensure that calcium nitrate is in a sealed container when not in use.
