What is the Shelf Life of Activated EM-1?Updated 5 months ago

The shelf life of activated EM-1 typically varies depending on storage conditions. 

Generally, activated EM-1 should be used within 1 to 2 months for optimal effectiveness. Cooler room temperatures (around 10-20°C or 50-68°F) can help prolong its viability. 

It's also important to store it in a dark place or away from direct light, with the lid tightly closed to maintain its quality. If it's a particularly good batch, it may last even longer, potentially up to 2 years or more. 

However, it's always good to check for any changes in smell, color, or pH as indicators of its condition.
