Hygrozyme Ingredients

Hygrozyme contains a specific blend of enzymes to accelerate the breakdown of dead root matter. The ingredients in Hygrozyme are specifically designed to work at their maximum strength in the optimal PH and temperate range. It is important to have the right enzymes for the right purpose. To break down dead roots cellulase enzymes are needed, this is why we list our four main enzymes on our label.

Cellulase 1,000 U/mL
Xylanase 100 U/mL
Hemicellulase 75 U/mL
Beta-Glucanase 40 U/mL

Since enzymes are specific in the reactions they catalyze, a diverse variety of enzymes must be present in the root zone to carry out all the different biochemical transformations required to break down the various components of the decaying plant material.
On that effect, only when the right type of enzyme finds the right substrate, does a biochemical reaction occur. This specific interaction between an enzyme and a substrate means you don’t have to worry about undesirable effects. For instance, when cellulase breaks down cellulose, that’s all that will happen. No other material or process will be altered or affected. That’s why it is important to have the right formula like Hygrozyme, designed specifically to get rid of the bad without affecting the good.
To ensure full satisfaction and 100% guaranteed results, Hygrozyme is manufactured in an ISO 9001:2015 certified production facility.

Hygrozyme Tissue Test

When choosing an enzyme product for plants, it is important to know if the enzyme formula contains the right enzymes to improve your indoor or outdoor grow system.

Tissue is essentially the same material as dead root matter (cellulose). The more the tissue breaks down, the higher the activity of the enzymes (cellulase) is in the product.

This simple test shows if the right enzymes are in the product to break down dead roots. Try the test at home by placing tissue in a cup of enzyme product. Keep it at room temperature for 24 hours. Shake and observe to see if the tissue paper disintegrates.

Here is what you need to know to compare products

To protect consumers, many states including California and Oregon require enzyme products to list its active ingredients on the product label. Regulatory authorities ensure that the declared units of active ingredients are in fact in the product. Check the ingredient list on the package and make sure that enzymes are actually in the product. Enzyme names are easy to identify, as most enzyme names end in “ase” as an example active ingredients in Hygrozyme are 1,000 U/mL cellulase, 100 U/mL xylanase, 75 U/mL hemicellulase and 40 U/mL beta-glucanase, which are also complimented by a unique blend of additional hydrolytic enzymes.
If N-P-K is declared on the product label, then the product is likely registered in the state as a fertilizer, not an enzyme. In this case, enzymes ingredients are not guaranteed.


Products that break down dead root matter should be registered as an enzyme. If it’s registered as a fertilizer or not registered at all, it likely won’t help with keeping your roots clean.

Manufacturers can’t claim that the product “breaks down dead root matter” if the product isn’t registered as an enzyme formula. Additionally, they must declare the type of enzyme and level of activity to prove that the product does, in fact, break down dead organic matter.

Frequently Asked Questions

Enzymes are proteins, made up of amino acids that act as catalysts – they facilitate, energize, and speed up biochemical reactions. In fact, the rate of reaction can be several million times faster than if left un-catalyzed! An extreme example is orotidine 5′-phosphate decarboxylase, which allows a reaction that would otherwise take millions of years to occur in milliseconds.

Enzymes are not alive nor are they consumed when they catalyze a biochemical reaction. When the biochemical reaction is over, the enzyme is ready to bond to another substrate unit again. Given the right conditions, the enzyme can catalyze the same reaction time and time again.

Enzymes are used in most industries to make some of your favorite things like: tastier beer, softer cloths, better cheeses and juices, more efficient detergents etc.

Enzymes are highly specific. Only when the right enzyme finds the right substrate, does a biochemical reaction occur. This precise interaction means you never have to worry about undesirable effects. For instance, when cellulase breaks down cellulose into simple sugars, you can be sure that is all that will happen. No other material or process will be altered or affected. This is why it is important to have the right enzyme formula like Hygrozyme designed specifically to get rid of the undesirable content without affecting the good.

Hygrozyme’s pH is between 4 – 4.5 (variance because our enzymes are derived from natural sources)

Mix 2-2.5mL per liter of water (never exceed 4 mL per liter) and flush your system. Stop using Hygrozyme one week prior to harvest. We recommended a gradual reduction of all nutrients starting 3 weeks from harvest the same way you gradually increased nutrients at the start. Stop using all nutrients and supplements one week prior to harvest including Hygrozyme. Only feed your plants water during the final week.

Depends on your nutrient or fertilizer program. We recommend to use Hygrozyme with every watering or nutrient change out. If you are adding beneficial microbials to your system, you have the option to add less beneficial microbials with every watering, as Hygrozyme helps speed up the process of microbial growth.

Hygrozyme accelerates the break down of dead root matter thereby removing the ideal environment for disease and root rot to start. Hygrozyme also stimulates microbial growth, which improves drainage and aeration. Improved drainage and aeration means that chances of root rot are further decreased.

You can use Hygrozyme in all soilless and soil medias. That being said, we do not recommend the use of Hygrozyme in your Aquaponics system.

Hygrozyme is the most effective without hydrogen peroxide, therefore, we do not recommend using H2O2 with Hygrozyme, but you can use up to 2 mL of H2O2 per gallon with Hygrozyme.

Yes, you can use beneficial microbials with Hygrozyme. Hygrozyme converts dead root matter into simple sugars which stimulate microbial growth (microbials consume simple sugars to multiply).

To preserve the shelf life and potency of the enzymes in Hygrozyme, the best place to store Hygrozyme is away from direct sunlight in a temperature range between 4-35° C (40-90° F).

Hygrozyme contains an industry leading concentration of 4 core enzymes: 1,000 U/mL Cellulase, 100 U/mL Xylanase, 75 U/mL Hemicellulase and 40 U/mL beta-Glucanase, which are also complemented by a unique blend of additional hydrolytic enzymes to assist in the effective breakdown of dead root matter.

Yes, it is recommended that you use Hygrozyme with every growth stage. However, we recommended that you flush and only feed your plants water on the last week before harvest.

No, Hygrozyme does not cure disease.

No, air pump will NOT cause enzyme shearing.

Yes. But since Hygrozyme is a complete multi-enzyme blend, no additional enzymatic products are needed.

Hygrozyme is compatible with all nutrient and supplement programs.

Yes, you can use Hygrozyme past the 2-year shelf life however for best results, we recommend Hygrozyme to be used within 2 years from the manufactured date. But Hygrozyme is designed to preserve and stabilize the activity of its highly effective enzyme blend. So if kept in appropriate storage conditions, the enzymes will still be active past the 2-year shelf life. If you plan to use Hygrozyme beyond the 2-year shelf life, continue with recommended usage instructions on the product label. DO NOT increase dosage.

Enzymes, unlike any other catalyst, are highly substrate specific and hence do not cause undesirable effects.

Yes, you can use Hygrozyme in a soilless or soil based medium.

Use Hygrozyme with every watering or nutrient change out.
