See How It Works

What’s inside?

Plant Enzymes is powered by the highly-active enzyme Cellulase — the biological catalyst that digests cellulose (the main substance in dead plant roots).

7,000 active units per mL, concentrated enough to work even in low-microbial environments like coco coir or DWC.
No foliar application required — always apply directly to the root zone.
Formulated for safety and versatility.

It’s not your vague "root booster." It’s a specific solution to a common grow issue: dead matter that blocks uptake and stresses your plants.

Customer Feedback

Plant Enzymes: What to know before you buy.

In hydroponic systems, coco coir, and aeroponics — where natural microbial action is limited — Plant Enzymes plays an even more critical role. It keeps the root zone clean and active by digesting dead root material.

Use Plant Enzymes with every feeding for consistent root zone health, or 1-3x per week for maintenance.

Plant Enzymes are a category of biological agents that catalyze (speed up natural breakdown processes. Ours uses Cellulase, a digestive enzyme that targets cellulose, the primary substance in decaying roots. When applied to your media, it turns unusable root waste into nutrient-rich material that your plant can reabsorb.

Yes — whether traditional potting soil, coco coir, aquaponics, DWC, or a recirculating hydroponic system, our clean formula integrates easily. Just avoid foliar use — this enzyme is made for the root zone.

Our gardeners see visible improvements in plant energy and root appearance within a few days. If you’re reusing soil or cleaning up after a stressed grow, you may notice better water absorption, less buildup, and stronger new root development.

Yes.Plant Enzymes is easy to test at home. Mix 10mL into one cup of water and drop in a 1x1 inch piece of paper. After 24 hours, shake the mixture. If the paper dissolves, the enzyme is active — that’s the same action it performs on root debris.

Plant Enzymes is fully compatible with all Humboldts Secret products and most other feeding programs. Always add Plant Enzymes after your base nutrients and adjust pH as needed. Do not mix concentrates together before dilution.

Command new growth — it starts at the root.

Every grow carries remnants of the last. Without intervention, they cloud the root zone and choke uptake. Plant Enzymes clears the slate, giving your plants a renewed foundation and unlocking stronger growth.
Relied on by home gardeners and commercial setups alike for visible results, made simple.
