PGP Plant Growth Promotor | Macrophyte Biostimulant | BTAqua

Biotech Aquatica PGP Plant Growth Promotor A completely organically derived macrophyte biostimulant — a macro, micro and trace nutrient complex engineered for sustained plant health and dense, lush growth without synthetic overdosing or unwanted vegetative elongation. 100% Organic 2.5-0.2-1.7 NPK Ratio 19+ Elements 100% Organic No Synthetic Fertilisers Phytohormones Macro · Micro · Trace Microbiology Support ✓ 100% Organically Derived ✓ No Chemical or Synthetic Fertilisers ✓ Phytohormone-Enriched ✓ Microbiology Safe ✓ Australian Made Being that you want sustained growth and health over pumping growth full throttle, a lower NPK with sustained release — with both macro, micro and trace elements — is the best fit. We don't want leggy growth. We want a complete feed and nutrient mix to keep your plants STRONG, because true growth is not just about speed — it's about resilience. PGP delivers growth hormones, amino acids, nitrogen, phosphorus and potassium bound into a single organic solution. No separate bottles. No synthetic shortcuts. Just a liquefied compost-style nutrient complex that builds your system from the substrate up. What Sets PGP Apart 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. Inside The Formula Complete Nutrient Architecture PGP provides a comprehensive suite of 19+ essential and beneficial elements, all organically derived and bioavailable — from primary macronutrients through to trace minerals critical for photosynthesis and enzyme function.

How To Use Quick Use Guide PGP is a concentrate. Dilute it, dose it, and let the organic chemistry do the work. 01 💧 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. 02 📊 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. 03 🌿 Watch The Biology Build Over weeks, the organic compounds develop substrate microbiology — creating a self-sustaining nutrient engine that improves with time.

Questions Frequently Asked Q. Is PGP a synthetic fertiliser? No. PGP is 100% organically derived. There are no chemical or synthetic fertilisers in the formulation. All nutrients are bound within an organic carrier matrix that releases gradually into the water column. Q. Will PGP cause algae outbreaks? PGP is specifically engineered with a low-impact NPK ratio (2.5 – 0.2 – 1.7) and sustained organic release to avoid nutrient spikes. This means nuisance algae are far less likely to trigger compared to synthetic fertilisers that dump available nutrients in one hit. Q. Will my plants grow leggy? No. Leggy growth is typically caused by high synthetic nitrogen driving rapid vegetative elongation. PGP delivers a balanced, complete nutrient profile that promotes dense, compact, healthy growth — not forced stretching. Q. Can I use this in my store holding tanks? Absolutely. PGP is designed for exactly that. Store holding tanks, wholesale production systems, display aquariums — the organic, low-impact formula keeps plants healthy without the maintenance headaches of synthetic regimes. Q. Can I hook this up to a doser? Yes. PGP is supplied as a concentrate. Add the required amount to a vessel, fill with RO or dechlorinated water, and connect to your dosing pump for automated delivery at 1 ml per 50 L. Q. What makes this different from standard aquarium plant fertilisers? Most aquarium fertilisers are synthetic salt-based solutions that deliver instant nutrients. PGP is an organic nutrient complex that provides macro, micro and trace elements alongside growth hormones, amino acids and total organic carbon — while actively building beneficial microbiology in your system. Q. Is it safe for shrimp and sensitive livestock? PGP contains no synthetic chemicals or harsh salts. The organic formulation is designed to work within the biological framework of your system. As with any product, we recommend starting at the standard dose and observing your livestock during initial use. Technical Support Not Sure If PGP Fits Your System?
