Cannazym

Cannazym Enzyme Root Treatment — Professional-Grade Enzyme Additive for Healthier Roots

Best for: Growers reusing substrate, managing root health in hydroponics, and preventing pathogen problems without breaking the budget

Cannazym is a concentrated enzyme additive from CANNA that breaks down dead root material, recycles it into usable nutrients, and keeps your root zone healthy. It contains 12 different enzymes plus vitamins and desert plant extracts, designed to work across any growing medium and any hydroponics setup. Simple idea: cleaner roots, fewer diseases, better nutrient uptake. One you use all growing cycle long.

How it compares

Cannazym sits in the professional-grade enzyme category.

• Outperforms competing enzymes in third-party breakdown tests — particularly effective on cellulose and dead root material
• Lacks organic certification, unlike some alternatives (Hygrozyme) — but performs better on raw breakdown
• Incompatible with hydrogen peroxide systems — something to know upfront if you run those
• Higher enzyme concentration per ml than most budget alternatives, so dosing is straightforward

In plain terms: you're getting the enzyme product that growers actually rate for serious root zone work, without paying premium brand markup.

Usage guidance

Standard feeding
Add 2.5ml per litre of nutrient solution. Works with any growing medium — coco, rockwool, soil, expanded clay, hydroponics tanks, the lot. Use throughout the entire growing cycle.

Substrate reuse (the big one)
Remove as much of the old root ball as you can, then soak your used growing media in a solution of 5ml per litre. Keep it wet for around 24 hours. The enzymes will break down the remaining dead roots and convert them into minerals and glucose your plants can use next cycle. Drain and dry to your preferred moisture level before replanting. This is where Cannazym earns its place — old media becomes fresh again, naturally.

Root zone management
Dead roots are a magnet for pythium and other root diseases, especially when temperatures climb. By keeping dead material broken down and cleared out, Cannazym reduces disease risk and maintains oxygen-rich air pockets in your substrate. Particularly valuable in summer or warm growing rooms.

Critical note: Never mix with hydrogen peroxide products — it'll kill the enzymes and they won't work.

Who this is for

• Growers reusing substrate cycle to cycle — this is where the real savings happen
• Hydroponics growers running warm environments where root disease risk is higher
• Anyone prioritising root health and nutrient recycling over optional extras
• Growers already running CANNA nutrient lines (integrates seamlessly)
• Medium to advanced growers who understand substrate management matters

Less essential for one-off media use or completely sterile systems, but genuinely useful if you're serious about root zone control.

Our take

Cannazym does the job it's supposed to do — breaks down dead roots, recycles them, and keeps disease pressure down. The enzyme blend is genuinely good; independent testing proves it outperforms competing products. It's not an essential add-on, but it pays for itself quickly if you're reusing substrate or managing disease risk.

Good time to buy while clearance stock lasts. Worth picking up if root health and substrate reuse matter to your setup.
