Enzymes on Plants. What the heck?
Update: 2025-09-24
Description
Dr. Russell Sharp investigates enzyme-based hydroponic products like Plagron's Green Sensation, questioning ingredient lists and the claim that sprayed enzymes break down plant cell walls.
He explains where enzymes are actually useful (breaking down dead roots and improving media nutrient availability), outlines stability limits (UV and temperature), suggests microbes or composting as better alternatives, and teases tomorrow's episode on arsenic in rice.
