Hygrozyme Hygroben Microbial Root Inoculant - 1 L - 3.6 x 3.6 x 8.4-in

Five-Strain Root Zone Support - 1 L Bottle

A root zone with few beneficial microbes gives plants less biological support during vegetative growth and flowering. Hygroben adds a microbial root inoculant built from five Bacillus species: B. licheniformis, B. subtilis, B. pumilus, B. amyloliquefaciens and B. megaterium. The label lists the concentration of each species in CFU/mL, so you can see what goes into your reservoir or media.

The 1 L bottle fits growers who want to add a root inoculant to a regular indoor routine or try it on a single system before scaling up. It stands 8.4 in tall on a 3.6 x 3.6 in footprint, so it stores easily on a shelf.

Frequently Asked Questions

Q: What is Hygroben?
A: Hygroben is a microbial root inoculant. It supplies five Bacillus species to the root zone of plants.
