Ultra-Micronised Guano Bloom Booster for Flower Density, Resin, Aroma, Colour & Yield

High Powered Organics MARIGUANO Bloom Booster is a concentrated, 100% active guano-based flowering biostimulant engineered to enhance flower development, nutrient utilisation, resin production, colour expression, aroma and overall crop quality during bloom.

Unlike conventional PK boosters that rely primarily on a heavy dose of immediately available phosphorus and potassium salts, MARIGUANO takes a more biologically compatible approach. Its foundation is ultra-micronised guano refined to below 50 microns, combined with potassium citrate, fermented botanical extracts, fulvic acid, targeted amino acids, polysaccharides and polyols.

The ultra-fine particle size increases the usable surface area of the guano, helping improve dispersion and availability while maintaining compatibility with biologically active growing systems.

MARIGUANO Bloom can be used at lower rates alongside an existing flowering nutrient program or at higher rates as a more substantial PK and metabolic bloom booster. Its highly concentrated dry formulation is suitable for living soil, organic soil, coco and compatible hydroponic systems.

A Different Approach to PK Boosting

Many conventional bloom boosters deliver large quantities of rapidly soluble phosphorus and potassium.

While this can increase the concentration of these elements in the nutrient solution, excessively aggressive PK supplementation isn't always ideal for biologically managed soils.

MARIGUANO approaches bloom supplementation differently.

Its flowering nutrition is built around ultra-fine guano combined with potassium citrate and biologically active compounds.

The objective is to provide flowering nutrition while also supporting:

Nutrient Availability + Plant Metabolism + Soil Biology + Secondary Metabolite Expression

This makes MARIGUANO particularly attractive to growers wanting strong bloom performance without abandoning a biologically focused cultivation program.

---

Ultra-Micronised Guano Technology

A defining feature of MARIGUANO is its sub-50-micron mineral refinement.

The mineral components are processed using controlled-temperature milling to reduce particle size to below approximately 50 microns.

This fine particle size provides:

• Greater surface area
• Improved dispersion
• Faster interaction with the growing environment
• Improved availability compared with coarse guano
• Better flowability
• Greater compatibility with irrigation-based applications

Traditional guano amendments can take considerable time to become biologically available.

By reducing particle size dramatically, MARIGUANO creates a much more responsive guano-based flowering input.

---

Guano-Based Flowering Nutrition

Guano has long been valued as an organic source of nutrients for flowering plants.

MARIGUANO takes this traditional organic amendment and adapts it for modern high-performance cultivation.

Rather than using coarse guano as a slow dry amendment, the micronised formulation is designed to provide a more responsive flowering effect.

This allows growers to incorporate guano-derived fertility into applications where conventional coarse organic amendments would be too slow.

---

Potassium Citrate

MARIGUANO Bloom incorporates potassium citrate alongside the guano complex.

This combination provides both potassium and citrate within the feeding solution.

Potassium plays major roles during flowering, including:

• Carbohydrate transport
• Water regulation
• Enzyme activation
• Nutrient movement
• Flower development
• Plant metabolism

The citrate component complements the citrate-soluble fraction of the guano, helping create a more readily available flowering nutrient system.

---

Fermented Comfrey & Hops

The Bloom formulation contains freeze-dried fermented botanical extracts, including comfrey and hops.

These botanicals provide naturally occurring plant compounds associated with flowering and secondary metabolism.

The fermentation process helps transform the botanical material before it is incorporated into the concentrated powder.

Within the Bloom formula, these botanical extracts are specifically selected to complement:

• Flower development
• Resin expression
• Terpene development
• Colour expression
• Secondary metabolite production

This differentiates MARIGUANO from basic mineral PK products that provide phosphorus and potassium without additional botanical biostimulants.

---

Fulvic Acid

MARIGUANO contains high-quality fulvic acid as part of its bioactive matrix.

Fulvic compounds can interact with mineral nutrients and support processes associated with nutrient availability and transport.

Within MARIGUANO, fulvic acid works alongside the ultra-micronised minerals, citrate and organic components to support efficient delivery of the nutritional payload.

---

Natural Chelator & Bioflavonoid Complex

The formula also incorporates a naturally derived chelator and bioflavonoid complex from citrus sources.

This component contributes to the nutrient-delivery and plant-active properties of MARIGUANO.

Citrus-derived compounds can provide naturally occurring:

• Bioflavonoids
• Organic acids
• Chelating compounds
• Plant-active compounds

Within the complete formula, these components are designed to support nutrient utilisation and expression during flowering.

---

Targeted Bloom Amino Acids

Rather than relying solely on a generic broad-spectrum amino acid mixture, MARIGUANO uses targeted amino-acid combinations selected for the flowering phase.

Amino acids participate in numerous plant processes, including:

• Protein synthesis
• Enzyme activity
• Cellular metabolism
• Stress response
• Secondary metabolism

The targeted approach is designed to provide metabolic support specifically when plants are directing significant energy toward reproductive growth.

---

Bioactive Sugar Matrix

MARIGUANO also contains a specialised matrix of polyols and polysaccharides.

These compounds contribute to biological and metabolic processes associated with:

• Osmotic regulation
• Microbial activity
• Enzymatic pathways
• Carbon availability
• Root-zone biochemical activity

This means MARIGUANO isn't simply supplying phosphorus and potassium—it is also designed to influence how effectively the broader biological system operates during flowering.

---

Supports Flower Stacking & Density

During flowering, plants redirect substantial resources toward reproductive growth.

MARIGUANO Bloom is designed to support this transition by providing targeted nutrition and metabolic inputs associated with:

• Flower initiation
• Flower-site development
• Flower stacking
• Flower density
• Structural filling
• Final crop mass

For high-output flowering crops, it can be layered into an existing nutrient program to provide additional support during periods of peak demand.

---

Resin & Trichome Development

MARIGUANO Bloom is also formulated around secondary metabolite expression.

Rather than focusing solely on flower mass, the formula is designed to support traits associated with crop quality, including:

• Resin production
• Trichome development
• Essential oil expression
• Terpene intensity
• Aroma
• Flavour characteristics

This makes it particularly useful for aromatic flowering crops where quality is determined by more than total harvested weight.

---

Colour Expression

The combination of fermented botanicals, bioflavonoids, amino acids and other plant-active compounds is designed to help plants express their natural genetic characteristics during bloom.

Depending on plant genetics and environmental conditions, this can contribute to stronger natural pigmentation and colour expression.

MARIGUANO does not create genetics that aren't present—it is designed to help plants express their existing potential under appropriate growing conditions.

---

Soil Application

MARIGUANO Bloom can be mixed directly into feed water for soil-grown plants.

General Bloom Support

Use:

0.1–0.4g per litre of feed water

This rate is suitable when MARIGUANO is being layered alongside an existing bloom nutrient or biostimulant program.

It provides additional flowering support without unnecessarily replacing the entire nutritional program.

High-Performance Bloom Application

Use:

0.5–1.0g per litre of feed water

At higher concentrations, MARIGUANO provides more substantial phosphorus, potassium and metabolic support.

This rate can function as a stronger standalone bloom booster or as part of an advanced flowering program.

---

Soil Feeding Guide

Application should be adjusted according to cultivar, existing fertility, container size and the rest of the feeding program.

Always dissolve thoroughly before application.

---

Coco & Hydroponic Application

The highly refined formulation allows MARIGUANO Bloom to integrate into coco and compatible hydroponic feeding programs.

General Use

0.1–0.4g/L

At this rate, MARIGUANO can complement an existing base nutrient and flowering program.

Growers may be able to reduce or replace conventional bloom boosters depending on the nutritional composition of the existing feed.

High-Performance Use

0.5–1.0g/L

At higher rates, MARIGUANO functions as a substantial biostimulant and phosphorus/potassium booster.

When increasing MARIGUANO, account for the nutritional contribution of every other product in the reservoir rather than automatically stacking multiple PK boosters at full strength.

Excellent for Living Soil

One of MARIGUANO Bloom's major advantages is its suitability for biologically active growing systems.

The guano component can interact with soil microorganisms while its ultra-fine particle size provides greater availability than traditional coarse guano amendments.

This makes MARIGUANO useful for:

• Living soil
• GRO-DIRT
• GRO-DIRT Lite
• Organic potting mixes
• Biologically managed coco
• Reusable soil

Growers can therefore add a responsive bloom booster without abandoning their biological cultivation strategy.

---

MARIGUANO Bloom + GRO-DIRT Lite

MARIGUANO Bloom is particularly useful with GRO-DIRT Lite.

Because GRO-DIRT Lite gives growers greater control over supplemental nutrition, MARIGUANO can be introduced as flowering demand increases.

This creates a flexible system combining:

Living Soil Biology + Responsive Bloom Nutrition + Metabolic Support

Application can be adjusted according to cultivar and flower development rather than relying solely on nutrients preloaded into the soil.

---

MARIGUANO Bloom + GRO-DIRT Full Spec

MARIGUANO can also complement GRO-DIRT Full Spec.

Because Full Spec already contains substantial organic nutrition, lower MARIGUANO rates may be appropriate when the goal is primarily metabolic and flowering support.

Increase only where plant demand and the existing soil fertility justify additional bloom nutrition.
