PGP
Plant Growth
Promoter
A completely organically derived macro, micro and trace nutrient complex — engineered for sustained plant health and dense, lush growth without synthetic overdosing or unwanted vegetative elongation.
The Difference
PGP is not another synthetic fertiliser dosed by the millilitre. It's a complete organic nutrient architecture — delivering sustained nutrition that develops the biological base of your system over time.
Sustained Release, Not Synthetic Spikes
Organically bound nutrients release gradually into the water column and substrate. No nutrient spikes that trigger algae blooms or leggy, unsustainable growth.
Phytohormone & Amino Acid Complex
Loaded with naturally derived growth hormones and amino acids that promote cellular health and stress resistance — not just green colour.
Microbiology Development
Micronised organic solids in the formulation actively feed and develop beneficial microbiology in your substrate, filter and water column.
Single-Part Concentrate
All macros, micros, trace elements, hormones and amino acids bound in one solution. Dilute, dose, done. No multi-bottle regimes.
Low-Impact NPK Engineering
Guaranteed analysis at 2.5 – 0.2 – 1.7 delivers precision nutrition without overshooting macronutrient levels that cause nuisance algae.
Commercial-Grade Versatility
Equally effective in store holding tanks, wholesale production, display aquariums and home planted setups. One product for every scenario.
Complete Nutrient Architecture
PGP provides a comprehensive suite of 12+ essential and beneficial elements, all organically derived and bioavailable — from primary macronutrients through to trace minerals critical for photosynthesis and enzyme function.
🌱 Dense, Lush Growth
Promotes healthy, compact foliage with strong cellular structure — the opposite of leggy, stretched growth caused by synthetic nitrogen overdosing.
🛡️ Stress Resistance
Phytohormones and amino acids build natural resilience against transplant shock, parameter fluctuations and environmental stressors.
🪱 Substrate Health
Micronised organic solids settle into the substrate, feeding beneficial biology and building a living nutrient bank that releases over weeks.
⚖️ Algae-Resistant Dosing
Low-impact NPK ratios with sustained organic release mean no nutrient overshoot — starving nuisance algae of the spikes they depend on.
🧫 Microbiology Boost
The organic carrier matrix actively cultivates nitrifying and heterotrophic bacteria, improving water quality alongside plant health.
💧 Doser Compatible
Supplied as a concentrate — simply add to a vessel, dilute with RO water, and connect to your dosing system for hands-free feeding.
Quick Use Guide
PGP is a concentrate. Dilute it, dose it, and let the organic chemistry do the work.
Dilute The Concentrate
Add the required amount of PGP concentrate to a clean vessel. Fill with RO or dechlorinated water to your desired dilution ratio.
Dose At 1 ml / 50 L
Apply at the standard rate of 1 ml per 50 litres of system water. Dose daily or connect to an auto-doser for consistent delivery.
Monitor & Adjust
Observe plant response over 2–4 weeks. For heavy root feeders or high-light systems, adjust dosage incrementally. Less is more with organic nutrition.
Watch The Biology Build
Over weeks, the organic compounds develop substrate microbiology — creating a self-sustaining nutrient engine that improves with time.
