THE GROWGANICA WAY / A FIELD GUIDE

Welcome to
the underground.

Your plant has a life below the surface.
Get to know the world that feeds it.

Sugars move out of roots. Soil organisms get to work. Nutrients cycle back. A thriving garden is a conversation between all of them.

Let's dig in

COME A LITTLE CLOSER

The real work
happens down here.

Follow the exchange between a plant and the living soil around it. Four connected stories. One underground world.

FIELD NOTES / BELOW THE SURFACE01 — 04

Roots start the exchange.Illustrated soil ecosystem

01 THE ROOT EXCHANGE

A little sugar.
A lot of possibility.

Leaves turn sunlight into sugars. Some of that carbon moves down through the roots and into the surrounding soil as root exudates.

For nearby organisms, those compounds are food. For the plant, this is the beginning of a relationship with the life around its roots.

Plant carbonRoot exudatesSoil life

02 THE SOIL FOOD WEB

Nothing works
alone down here.

Bacteria and fungi break down organic matter. Other organisms feed on them. As that food web turns, nutrients move between living things and the soil.

When organic nutrients become mineral forms roots can take up, that process is called mineralization.

Organic matterSoil food webMineral nutrients

03 NITROGEN FIXATION

The air has it.
Biology unlocks it.

Atmospheric nitrogen gas — N₂ — is abundant, but roots cannot use it directly. Certain bacteria can convert it into biologically usable nitrogen.

That is nitrogen fixation. It brings nitrogen from the atmosphere into biology, rather than releasing nitrogen already held in organic matter.

N₂ in the airNitrogen-fixing bacteriaThe food web

04 THE HABITAT

Leave a little
room for life.

The spaces between soil particles hold water and air. Roots need oxygen, and so do many of the organisms working alongside them.

Organic matter, good drainage, and careful watering help shape this habitat. Biology needs suitable conditions as much as it needs food.

Check the root zone. A dry surface does not tell the whole moisture story.

Keep the pores open. Avoid compacting planted beds; make sure containers drain.

Keep organic matter in the plan. Give the wider food web material to work with.

Growganica Microbes full-spectrum compost tea bottle — Soil life, bottled.
**Just add water.**

MEET MICROBES

Put nitrogen-fixing
biology to work.

A whole community. An important job.

Our full-spectrum compost tea brings bacteria, fungi, and protozoa into the watering routine. Growganica’s microbial profile lists organisms with roles in nitrogen fixation and phosphorus solubilization.

NITROGEN FIXATION

Air has nitrogen.
Biology holds the key.

Roots cannot take up atmospheric nitrogen gas directly. Nitrogen-fixing bacteria can convert it into biological forms of nitrogen — a capability identified in our Microbes profile.

N₂in the airMicrobialconversionNitrogenin the food web

That nitrogen may reach plants through further cycling in the soil community. How much is fixed depends on the organisms and growing conditions.

The concentrate is made from four ingredients:

Shared ground.

A working soil community has many roles. Get to know three groups in the food web behind the bottle.

01 / THE CHEMISTRY CREW

Bacteria

Different bacteria transform nutrients. Our product profile includes nitrogen-fixing and phosphorus-solubilizing roles.

02 / THE BREAKDOWN CREW

Fungi

Branching fungal threads help break down complex organic material and move carbon through soil life.

03 / THE GRAZING CREW

Protozoa

Microscopic grazers feed on bacteria, helping return nutrients held in microbial bodies to the wider food web.

Illustrated soil-life roles. Explore the full Microbes story, the formula, and how it compares with home-brewed teas and dry inoculants.

A ROUTINE WITH A REASON

Care for the soil.
Feed the stage.

Microbes, Veg, and Bloom have different jobs. Match the feeding chapter to what your plant is doing now.

Biology needs a meal.

Soil organisms need food and suitable conditions to do their work. Roots supply carbon through exudates; organic inputs become part of the wider food web. Our system pairs the compost-tea step with Veg or Bloom for the plant’s current stage. Biology and nutrition belong in the same plan.

01 / THE SOIL-CARE STEP

Microbes

The compost-tea step stays in the routine through the growing stages.

Choose a power-up to look closer01 — 05

POWER-UP 010.1–10–25

Incredible Bulk

Rock phosphate · Sulfate of potash · Kelp

Phosphorus: energy transfer. Potassium: water regulation and sugar movement.

THE FLOWERING POWER-UP

Flower power has a job description.

Flowers and fruit ask a lot of a plant. Incredible Bulk adds focused phosphorus and potassium to support the work happening inside.

WHAT’S HAPPENING INSIDE

Phosphorus helps transfer energy within plant cells. Potassium helps regulate water and move sugars from the leaves to other growing parts. These are everyday plant processes that matter while flowers and fruit develop.

Reach for it when: Your plant is entering flowering or fruiting, and your nutrition plan calls for extra phosphorus and potassium.
Its place in the system: Bloom handles the flowering-feed role. Incredible Bulk adds a focused P-and-K boost alongside it, with Microbes in the soil-care step.

A little goes a long way

POWER-UP 020–0–14

Kelp It Real

Soluble Ascophyllum nodosum seaweed extract

Seaweed extract supplies potassium, which helps the plant manage water and move sugars.

THE SEAWEED POWER-UP

A little ocean. Throughout the grow.

Kelp It Real brings soluble Ascophyllum nodosum seaweed into the routine, along with a clear potassium contribution.

WHAT’S HAPPENING INSIDE

Potassium helps the tiny pores in leaves open and close, supports enzyme activity, and helps move sugars around the plant. The kelp extract also brings seaweed-derived organic compounds into the watering routine.

Reach for it when: You are settling transplants into their new home, or want a seaweed companion through active growth and flowering.
Its place in the system: Pair its seaweed-and-potassium role with Veg or Bloom. Microbes provides the separate compost-tea step for the root zone.

POWER-UP 0310% calcium

King Krustacean

Crustacean meal · Seaweed · 8% humic acid

Two roles: calcium for growing tissue, and chitin as a food source for decomposer organisms.

THE CALCIUM + CHITIN POWER-UP

From ocean shells to soil life.

King Krustacean connects two parts of the garden: calcium for the plant, and a chitin-containing crustacean input for the soil community.

WHAT’S HAPPENING INSIDE

Calcium helps build plant cell walls and growing tissue. Chitin is a structural material in crustacean shells; organisms that can break it down use it as a food source. King also contains humic acid derived from leonardite.

Reach for it when: Calcium and a crustacean-based soil input fit your growing medium and nutrition plan. It can be used through the growing stages.
Its place in the system: Microbes brings the living community. King brings a chitin-containing input and calcium; Veg or Bloom stays in the stage-feed role.

POWER-UP 043% Mg + 0.02% B

Vitamin Sea

Derived from concentrated sea water

Magnesium is part of chlorophyll. Boron supports cell-wall structure and growing tissue.

THE SEA-MINERAL POWER-UP

The green in your leaves has a mineral story.

Vitamin Sea brings concentrated sea minerals to the routine. Two worth knowing: magnesium and boron.

WHAT’S HAPPENING INSIDE

Magnesium sits at the centre of chlorophyll, the green pigment that captures light for photosynthesis. Boron contributes to cell-wall structure and developing tissue. Small nutrients play specific roles beyond NPK.

Reach for it when: Your feeding plan calls for magnesium and boron on crops recommended by the label. A soil or tissue test can help identify that need.
Its place in the system: Add the mineral role beside Veg or Bloom. Kelp It Real provides seaweed and potassium; Vitamin Sea provides a different sea-mineral contribution.

Phishy

Fish protein hydrolysate · Stabilized with phosphoric acid

Fish-derived organic inputs join the soil food web, alongside a measured nitrogen and phosphorus contribution.

THE FISH-NUTRITION POWER-UP

Feed growth. Give soil life something to work with.

Phishy is fish protein hydrolysate: fish-derived nutrition in a liquid concentrate, with a nitrogen-and-phosphorus role in the feeding plan.

WHAT’S HAPPENING INSIDE

Nitrogen helps plants build proteins and chlorophyll. Phosphorus supports energy transfer and developing roots. The organic compounds in fish hydrolysate also give soil organisms material to break down as nutrients cycle.

Reach for it when: Plants are actively growing and a fish-based nitrogen and phosphorus input fits your existing nutrition plan.
Its place in the system: Use it as a planned feeding step. If applying with Microbes, add Microbes to the water first. Check compatibility before combining it with other fertilizers.

A little goes a long way

5 mL / gallon

ONE MORE THING BEFORE YOU GROW

Stay curious.
Take notes.
Look closer.

A good routine responds to your garden. Check moisture, light, and growth alongside what you add. A soil test can help identify nutrient and pH needs.

Keep learning

Where should I start?

Start with your growing medium, plant stage, and current inputs. Get to know the soil-care step and the appropriate stage feed. Add targeted products when their nutrient contribution fits your plan.

Can I mix everything together?

Follow each product’s preparation, rate, and compatibility directions. The Microbes label says to add it to water first, then Veg or Bloom. Mix close to application and do not store diluted Microbes.
