Yes, but we do recommend using the product soon after mixing it with water.  However, if the product is left for a prolonged period after mixing with water, it is normal for the emulsion to separate after mixing with water.  If this is the case, simply shake or stir it back into the milky white emulsion before using.

The mixture can last up to 2 weeks upon dilution with water as long as it is stored in a closed container in a dry cool place away from the sun. When ready to use, simply shake or stir it back into the milky white emulsion before using.

Since there are numerous plant varieties which may react differently to Hygropunch™, we recommend trying the product on a small area or a few plants to check for burn before using on a large scale, especially for delicate young plants. Apply early or late in the day on outdoor use.  Apply with lights turned off on indoor use.
