Breaks down dead root matter before it turns into a problem
Sensizym is an enzyme product that digests dead root material and organic debris in the medium, converting it into simple sugars the plant and the beneficial microbes can use, instead of leaving it to rot.
Key Benefits
- Clears dead root matter - a plant sheds roots constantly and they have to go somewhere
- Turns waste into food - broken-down material feeds the biology rather than the pathogens
- Keeps a reused medium viable - the main reason a second run underperforms
- Reduces root disease pressure - decaying matter is what pathogens colonise first
- Works with beneficials - enzymes and microbes are complementary
A medium that goes sour halfway through
Roots die back continuously through a cycle. In a recirculating system or a reused medium that debris accumulates, rots, and becomes the food supply for exactly the pathogens you do not want. It shows as weak roots and a brown, smelly root zone in late flower.
How to Use
- Whole cycle: 2 ml per litre at every feed
- Reused medium: 3 ml per litre for the first two feeds of a second run
- With beneficials: safe to use alongside bacteria and fungi products
- Reservoir: keep temperature under 22°C - enzymes denature in a warm tank
- Media: hydroponics, coco and soil
