GROWGANICA MICROBES / UNDER THE SURFACE

Meet your
underground
workforce.

Bacteria. Fungi. Protozoa.
Small life with a place in the bigger picture.

Our full-spectrum compost tea brings soil biology into your watering routine. Let’s look inside the bottle—and at what happens beyond it.

01 / MEET THE CREW

Different jobs.
Shared ground.

“Microbes” covers more than one kind of organism. These are three groups in the soil-food-web story behind our compost tea—and why their relationships matter.

01 / BACTERIA

THE CHEMISTRY CREW

Tiny organisms.
Many different jobs.

Different bacteria use root-released sugars and other organic compounds. Some transform nutrients; some make certain bound nutrients more soluble.

In the Growganica profile

Nitrogen-fixing organisms work with atmospheric N₂. Phosphorus-solubilizing organisms help make some existing soil phosphorus more accessible. Both roles are listed in our product profile.

02 / FUNGI

THE BREAKDOWN CREW

Fine threads.
Bigger connections.

Many soil fungi grow as branching threads called hyphae. Decomposer fungi break down complex organic materials and help move carbon through the food web.

Know the distinction

Fungi is a broad group. Mycorrhizal fungi form a specific partnership with roots; look for documented organisms and root-contact directions when choosing a mycorrhizal inoculant.

03 / PROTOZOA

THE GRAZING CREW

The food web
keeps moving.

Many soil protozoa graze on bacteria. As they feed, nutrients held in microbial bodies can return to forms that plants and other organisms use.

Why a community matters

Eating, growing, and decomposing are part of nutrient cycling. It is a set of relationships, with moisture, oxygen, temperature, and food shaping the activity.

Illustrated field notes: these drawings introduce general soil-life groups and their roles. See the sources below for more on the biology.

02 / ONE PARTICULARLY INTERESTING JOB

There’s nitrogen
in the air.
Biology can unlock it.

Roots cannot use atmospheric nitrogen gas directly. Nitrogen-fixing bacteria can convert N₂ into ammonia, bringing that nitrogen into biological circulation.

Our supplied Microbes profile identifies nitrogen-fixing roles within the community. That makes nitrogen fixation part of the product’s biology story.

  1. N₂
    01 / ATMOSPHERIC NITROGEN

    In the air.

    Nitrogen gas is abundant, but it is not a form roots can absorb directly.

  2. N₂ NH₃
    02 / BIOLOGICAL FIXATION

    Converted by bacteria.

    Specialized bacteria use energy and the enzyme nitrogenase to carry out this conversion.

  3. 03 / THE WIDER FOOD WEB

    Then it cycles.

    Nitrogen enters microbial life. Further turnover and mineralization can make it available to plants.

Fixation brings nitrogen in.
Cycling moves nitrogen through.

These are related processes, with different jobs. The amount fixed depends on the organisms and conditions. Keep Microbes paired with stage-appropriate nutrition and a suitable root environment.

THE LIQUID ROUTINE

03 / INSIDE THE BOTTLE

The community.
The ingredients.
The convenience.

Four source ingredients. One liquid concentrate.

VermicompostFish protein hydrolysateSoy protein hydrolysateSeaweed

Microbes is derived from these four ingredients. The formula belongs in a soil-care routine alongside the nutrition your plant needs for its current stage.

  1. 01

    Skip the home brew cycle.

    No brewer, air pump, or brew-time calculation is part of the retail directions. Shake the concentrate, measure it into water, and apply.

  2. 02

    Give biology a regular place.

    The label’s 1–3 mL per gallon makes the soil-care step easy to measure into your watering routine. Mix only what you will use.

  3. 03

    Keep the whole plan together.

    Add Microbes to the water first, then Veg or Bloom. Biology, nutrition, and a suitable root environment work together in your growing plan.

The biology
Bacteria, fungi, and protozoa in a liquid compost-tea concentrate. A community shaped by your compost, water, ingredients, and brewing method. The organisms listed on the product label. Formulations vary widely.
What you do
Shake. Mix 1–3 mL per gallon, before Veg or Bloom. No home brewing. Prepare the tea, clean equipment, and manage timing. Aerated methods need an air supply. Apply, hydrate, or place near roots as directed by that product’s label.
Why it may fit
A measured soil-care step in your usual watering routine. You want to choose your compost and manage the brewing process. You want specified organisms or a purpose, such as a documented mycorrhizal inoculant.
What to check
Use diluted mix promptly. Keep concentrate out of sun, below 100°F / 38°C, and protected from freezing. Best within one season of opening. Brews vary. Follow a sound method, application timing, and relevant food-crop guidance. Check organism identity, viable counts, expiry, storage, and root-contact instructions. Dry does not mean lifeless.

05 / FROM THE BOTTLE TO YOUR GARDEN

Make room for
the life below.

Good biology needs a suitable home. Keep moisture, oxygen, organic inputs, and your plant’s actual nutrient needs in the picture.

PER GALLON OF WATER1–3 mL

Apply with each watering.
Follow the directions on your bottle.

  1. Shake the concentrate.

    Measure the label-directed amount into water.

  2. Microbes first. Stage feed next.

    Add Microbes to the water first, then Veg or Bloom as directed. Check compatibility before adding other products.

  3. Mix for today’s application.

    Use the diluted mixture promptly; do not store it for later. Keep the concentrate out of direct sunlight, below 100°F / 38°C, and protected from freezing. Use within one season of opening for best results.
