Hygrozyme Hygroben Microbial Root Inoculant - 4L

Five-Species Root Zone Inoculant - 4L Bottle

A thin population of beneficial microbes around the roots leaves plants with less support during vegetative growth and flowering. Hygrozyme Hygroben is a microbial root inoculant that introduces five Bacillus species to the root zone: Bacillus licheniformis, Bacillus subtilis, Bacillus pumilus, Bacillus amyloliquefaciens and Bacillus megaterium. The label lists each species by concentration in CFU/mL, so you know what the bottle contains.

The 4L bottle suits growers who run a regular indoor room or several hydroponic systems and want enough product for repeated use. It is sold as a single bottle, so you can try it on one cycle before you scale up.

Key Features & Benefits

• Five Bacillus species — a broad microbial blend in one product instead of a single strain.
• Stated CFU/mL counts — you can see the concentration of each species.
• Made in an ISO 9001 certified facility — production runs under a recognized quality management system.
• Liquid 4L format — a bottle sized for repeated use across several applications.

Who Should Use Hygrozyme Hygroben

Hygroben suits home growers and licensed commercial cultivators who want to add beneficial microbes to the root zone of ornamentals, vegetables and flowering plants. It fits growers in hydroponic systems and in soil-based setups.

Frequently Asked Questions

Q: What is Hygroben?
A: Hygroben is a microbial root inoculant. It contains five Bacillus species that are intended to work together in the root zone.

Q: What does CFU/mL mean?
A: CFU stands for colony-forming units. It counts the viable microbes in each milliliter of product, which tells you how concentrated the inoculant is.

Q: Which plants can I use it on?
A: The manufacturer lists it as suitable for ornamentals, vegetables and flowering plants. Check the label for application rates and directions.

Q: How is an inoculant different from a nutrient?
A: A nutrient feeds the plant directly. An inoculant adds living beneficial microbes to the root zone. Many growers use the two together.

Q: Does this bottle contain a single dose?
A: No. It is one 4L bottle intended for repeated applications. Follow the label for how much to use per application.

Q: Who makes Hygroben?
A: Hygrozyme makes it. The company produces it in an ISO 9001 certified facility.
