Plagron Hydro a+b 2 x 5l
The Plagron Hydro A+B 2 x 5L delivers the same proven two-component hydroponic formulation in a cost-efficient volume format. With 10 litres of concentrated base nutrient, growers operating multiple systems or running consecutive cycles can maintain uninterrupted supply at a significantly reduced per-litre cost. Hydro A (NPK 5-0-2, CaO 8.8%) and Hydro B (NPK 2-4-9, MgO 1.4%) combine DTPA-chelated trace elements for stable uptake across pH 5.5 to 6.5 on all inert substrates. At 2.5 ml per litre dilution, this package generates up to 4,000 litres of working nutrient solution. A practical choice for experienced hydroponic growers seeking efficiency without compromising quality. Available in our Belgian growshop.
Plagron Hydro A+B 2 x 5L – High-Volume Hydroponic Base Nutrition for Serious Growers
Scaling a hydroponic operation requires a nutrient supply that matches both your ambition and your budget. The Plagron Hydro A+B 2 x 5L provides exactly that: a substantial volume of proven two-component base nutrition at a price point that makes economic sense for growers moving beyond the hobbyist stage.
Performance Data and Yield Efficiency
At the recommended maximum dosage of 2.5 ml per litre of water, 5 litres of Hydro A generates 2,000 litres of nutrient solution. Paired with the 5 litres of Hydro B, this package supports thousands of litres of irrigation – enough for multiple complete cycles depending on system size and plant count. The high concentration eliminates the waste associated with weaker formulations that require higher dosing volumes.
Technical Specifications
The formulation is identical across all packaging sizes. Hydro A: water, calcium nitrate, magnesium nitrate and potassium chloride. NPK fertiliser (5-0-2), 5% total nitrogen (N) as nitrate nitrogen, 2% water-soluble potassium oxide (K2O), CaO 8.8%. Hydro B: EC fertiliser, NPK solution (2-4-9), 2% total nitrogen (N), 4% water-soluble phosphorus pentoxide (P2O5), 9% water-soluble potassium oxide (K2O), MgO 1.4%. All trace elements in DTPA-chelated form ensure consistent bioavailability between pH 5.5 and 6.5.
Integration with the Plagron 100% HYDRO Schedule
Hydro A+B serves as the backbone of Plagron's dedicated hydroponic programme. Enhance results by adding Hydro Roots during the early vegetative phase to accelerate root establishment. In the flowering stage, Green Sensation 5L acts as a powerful bloom booster. For growers using recirculating systems, Pure Zym breaks down dead root material and keeps the medium clean – critical for maintaining optimal nutrient uptake over extended cycles.
Storage and Handling Guidelines
Store both 5L containers upright in a cool, dark location. Each full container weighs approximately 6 kg. Ensure caps are tightly sealed after use to prevent oxidation. Always add Hydro A and Hydro B separately to water – never combine the concentrates directly, as this causes mineral precipitation and nutrient lockout. Use a graduated measuring cup or syringe for accurate dosing at this volume.

How many litres of nutrient solution does Plagron Hydro A+B 2 x 5L produce?
At the maximum dosage of 2.5 ml per litre, 5 litres of Hydro A yields approximately 2,000 litres of working solution. Combined with the 5 litres of Hydro B at the same ratio, this package supports thousands of litres of complete nutrient solution – sufficient for multiple growing cycles in most setups.
Is Plagron Hydro A+B compatible with recirculating hydroponic systems?
Hydro A+B is fully compatible with both drain-to-waste and recirculating systems. The formulation prevents crystallisation in the nutrient reservoir, which is essential for closed-loop setups. Monitor EC and pH levels regularly in recirculating systems to maintain optimal nutrient availability.
Why must Hydro A and Hydro B be added to water separately?
Hydro A contains calcium while Hydro B contains phosphates and sulphates. Mixing the two concentrates directly causes these minerals to precipitate, forming insoluble compounds that become unavailable to plants. Always dilute each component separately in water to maintain full nutrient bioavailability.
What is the difference between Plagron Hydro A+B and Cocos A+B?
Hydro A+B is optimised for fully inert substrates such as clay pebbles, rockwool and perlite. Cocos A+B is specifically formulated for coco coir, which naturally retains and releases certain cations. Using Hydro A+B on coco may lead to nutrient imbalances – choose Cocos A+B for coco-based grows.
