Abstract
An electrochemically treated solution and method for cut flower and plant preservation, the solution having potassium, hypochlorous acid, and dissolved oxygen.
Claims16
A solution for cut flower and plant preservation consisting of:
- at least 99.5% by weight water;
- an effective amount of potassium chloride;
- an effective amount of but no more than 0.01% by weight hypochlorous acid, wherein the hypochlorous acid is supplied in an undissociated form;
- and
- an effective amount of dissolved oxygen,
- wherein the solution is electrochemically treated, has a total dissolved solids level of no more than 9 g/L, has a conductivity of 0.2-18 mS, has 5-600 ppm of available free chlorine equivalent, and has a pH of 4 to 6.

A solution for cut flower and plant preservation consisting of:
- at least 99.5% by weight water;
- an effective amount of but no more than 0.25% by weight potassium chloride;
- an effective amount of but no more than 0.01% by weight hypochlorous acid;
- and
- an effective amount of but no more than 0.001% by weight dissolved oxygen,
- wherein the solution is electrochemically treated and has a pH of 4 to 6 and a conductivity of 0.2-6 mS.
3 more elements
A method of extending cut flower and plant life comprising:
- providing an electrochemically treated aqueous solution wherein the solution consists of potassium chloride, hypochlorous acid, dissolved oxygen, has a total dissolved solids level of no more than 9 g/L, has a conductivity of 0.2-18 mS, has 5-600 ppm of available free chlorine equivalent, and a pH of 4 to 6;
