House & Garden Multi Zyme — Enzyme Additive for Faster Growth and Cleaner Root Zones
Best for: Growers running serious feeding programmes who want faster growth, cleaner root systems, and better nutrient uptake without overcomplicating things
Our thoughts
Multi Zyme is one of those additives that actually delivers. It's not flashy, but it works—breaking down dead root material, converting nutrients into forms your plants can actually use, and keeping your root zone productive. It's a premium product with a premium reputation, and for growers serious about feeding programmes, it's worth the investment.
House & Garden Multi Zyme is a powerful enzyme additive packed with 12 active enzymes, coenzymes, and a complete vitamin B complex. It's designed to accelerate growth, strengthen plant immunity, and unlock nutrient efficiency across soil, coco, and hydroponic systems. The enzymes break down dead root material and convert your base nutrients into forms your plants can absorb more easily—basically doing the work that microbes would do in natural soil, but faster and on demand.
How it compares
Multi Zyme sits at the premium end of the enzyme additive market.
- 12-enzyme formulation with B vitamins — more complex than basic single-enzyme products
- Medical-grade purity, cleared for licensed professional growing operations
- Works across all substrate types (hydro, coco, soil) without system-specific limitations
- Priced higher than some competitors like Sensizym and Hygrozyme, but growers report noticeably better results in established systems
Think of it as the difference between a basic cleanser and a purpose-built root zone revitaliser. You're paying for formulation depth and proven results.
Usage guidance
Dosing
Add 1ml of Multi Zyme per litre of nutrient solution. Mix well after adding your base nutrients but before checking pH and EC.
Timing
Use Multi Zyme throughout the entire growing cycle—from establishment through to finish. It's not a starter booster; it's a consistent additive that works best run continuously.
In hydroponics
Multi Zyme shines in hydro systems where dead root matter and organic waste can accumulate without natural microbial breakdown. The enzymes keep your nutrient film clean and your root zone efficient.
In coco
Coco substrates benefit hugely from enzymatic support. Multi Zyme breaks down the coir's organic compounds and ensures your nutrients stay bioavailable across the pot.
In soil
Use it as a supplement to natural soil biology—it amplifies what's already happening and accelerates nutrient cycling.

Who this is for
- Growers running complete feeding programmes with multiple additives
- Hydroponic and coco growers where natural microbial activity is limited
- Anyone with established systems where root zone waste has started accumulating
- Commercial and licensed professional growers prioritising medical-grade products
- Serious home growers willing to invest in nutrient efficiency and plant health
Not essential for casual growers on a tight budget, but genuinely valuable for anyone running more than a couple of pots and wanting noticeable improvements in growth speed and root health.
Our take
This is premium-tier enzyme additive, and the price reflects that. But the 12-enzyme formulation, vitamin support, and medical-grade standards actually deliver results—faster growth, cleaner root zones, and measurably better nutrient uptake across all system types.
If you're building a serious feeding programme and your root zones are working hard, worth picking up. Does exactly what it should, day in, day out.
