Unlock Maximum Yields with THC Coco A&B

The THC Coco A&B (Total Horticultural Concentrate) is a premium high-concentrate 2-part coco coir nutrient system engineered specifically for Australian coco growers. Coco coir's high cation exchange capacity (CEC) naturally binds calcium and magnesium, causing deficiencies and limiting growth. THC Coco A&B is formulated to counteract this — delivering elevated Calcium, Magnesium, and Iron for consistent nutrient uptake and optimal plant performance across both vegetative and flowering stages. No separate Cal-Mag required. Just one complete system from first feed to final harvest.

Vegetative Stage | Explosive Growth & Root Development

During the vegetative phase, THC Coco A&B delivers a high-nitrogen, calcium-rich formula that builds the structural foundation your plants need for a heavy-yielding harvest.

Rapid Root Development: Supports aggressive root expansion in coco coir — essential for efficient nutrient uptake throughout the grow cycle.
High Nitrogen for Fast Canopy Growth: Drives rapid leaf production, side branching, and canopy expansion for maximum light absorption.
Calcium for Structural Strength: Promotes thick stems and strong plant structure, preparing plants for heavy flowering loads.
Magnesium for Chlorophyll Production: Maintains deep-green foliage and efficient photosynthesis throughout the vegetative phase.
Stable Coco Nutrient Uptake: Prevents common coco issues including yellowing, slow growth, and nutrient lockout.

Flowering Stage | Bigger Flowers & Maximum Yield

As plants enter flowering, THC Coco A&B shifts to a high phosphorus and potassium-driven profile, maximising flower formation, fruit development, and final harvest weight — while maintaining balanced Cal-Mag levels to prevent late-stage deficiencies.

High Phosphorus for Flower Initiation: Triggers rapid bud formation and a strong, sustained flowering response.
Elevated Potassium for Yield & Density: Increases flower size, density, and overall harvest weight.
Continued Calcium Support: Strengthens plant structure to support heavy flowers and prevent collapse under yield pressure.
Magnesium & Iron for Plant Health: Maintains chlorophyll levels and supports energy production during the high-demand bloom stage.
Consistent Coco Nutrient Uptake: Prevents lockout and ensures reliable feeding right through to harvest.

Why THC Coco A&B Outperforms Generic Coco Nutrients

CEC-Balanced Coco Formula: Purpose-built to overcome coco lockout and deliver stable, consistent nutrient uptake across the full grow cycle.
Built-In Cal-Mag — No Additives Required: Elevated calcium and magnesium levels eliminate the need for separate Cal-Mag supplements.
Ultra-Concentrated for Maximum Value: Use less nutrient per litre while achieving faster growth and higher yields — ideal for hobby and commercial growers alike.
Advanced Chelation Technology: Keeps micronutrients available across a wider pH range, reducing deficiencies and improving overall plant performance.
Pharmaceutical-Grade Purity: Free from chlorides, sodium, and urea — clean feeding for healthy roots and efficient uptake.
Multi-System Compatible: Optimised for coco coir run-to-waste systems while remaining fully compatible with hydroponics and soil.

How to Use

Stage: Suitable for full grow cycle — vegetative and flowering
Mixing: Add Part A to water first, mix thoroughly, then add Part B. Never mix concentrates directly.
Dosage: 2ml–4ml per litre — adjust based on growth stage
Target pH: 5.8–6.2 for optimal coco nutrient uptake

THC Coco A&B is the complete, high-concentrate coco coir nutrient system for Australian growers who demand deficiency-free growth, explosive flowering, and maximum harvest weight — without the complexity of multi-additive feeding programs.

Frequently Asked Questions

How do I mix THC Coco A&B correctly?

Always add nutrients to water, never add water to concentrated nutrients. Fill your reservoir with the target volume of fresh water first, then add each part of THC Coco A&B separately, stirring between additions. If using a multi-part formula, add micro or Part A first, then grow or bloom, then any additives. Measure pH and EC after mixing and adjust to your target range — typically 5.8–6.2 pH and 1.4–2.2 EC for most crops.

What is the shelf life of THC Coco A&B?

Unopened, THC Coco A&B has a shelf life of 2 years when stored in a cool, dark location out of direct sunlight. Once opened, use within 12 months. Shake or stir well before each use as some formulations can settle. Do not freeze concentrated nutrients as this can cause precipitation of minerals that will not fully redissolve.

Can I use THC Coco A&B in soil as well as hydroponics?

THC Coco A&B is formulated for hydroponic systems but can be used for soil and coco growing at adjusted rates. Soil typically requires lower EC than hydro or coco as nutrients are buffered by the growing medium. Start at 50–70% of the recommended hydroponic dose when applying to soil and increase based on plant response.

How do I dispose of leftover nutrient solution made with THC Coco A&B?

Dilute spent nutrient solution with water and use it to water outdoor garden beds or lawns — it is an excellent fertiliser for outdoor plants. Avoid disposing of large volumes directly into storm drains. In residential situations, diluted nutrient runoff down a household drain is acceptable in small quantities.

Does THC Coco A&B ship fast within Australia?

Yes — THC Coco A&B ships from our Australian warehouse with fast tracked delivery Australia-wide. Most east coast orders arrive within 2–5 business days. WA, NT, and TAS orders typically arrive within 5–12 business days.
