Gain total operational control over your active growing systems with Plagron Hydro A & B. This professional-grade, highly concentrated two-part mineral base nutrient is engineered specifically for use throughout both the vegetative growth phase and the flowering period.

Formulated exclusively for cultivation in all types of inert hydroponic substrates, Hydro A & B delivers a complete combination of immediately absorbable nutrients and vital trace elements. Because inert mediums contain zero background nutrition, this clean liquid feed provides precision control over your exact EC (Electrical Conductivity) and pH values, driving maximum growth velocity and heavy final yields.

Core Cultivation Advantages:

Complete EC & pH Control: Free from unpredictable organic variables, Hydro A & B allows you to steer your crop's nutrition with total precision. You can adjust your reservoir concentration to the exact decimal point required by your plants.
Hydro A Heat Shield (Calcium Rich): Hydro A is packed with high-grade, bio-available calcium. Calcium is critical for fortifying cell walls, enhancing structural integrity, and protecting your plants against high temperature spikes and heat stress.
Hydro B Chlorophyll Engine (Magnesium Rich): Hydro B delivers a concentrated dose of magnesium, which is the foundational building block of chlorophyll. This enhances your plant's photosynthetic capacity, resulting in lush green leaves and rapid cell expansion.
Anti-Crystallisation Formula: Crafted from ultra-pure, technical-grade mineral salts, this sediment-free formula will never crystallise or clump inside your nutrient tank. It keeps your pumps, pipework, and fine hydroponic drip lines completely clear of blockages.

Dosing & Phase Ratios

Plagron Hydro A & B must always be used in equal parts throughout the plant's life cycle. Adjust the strength of the solution to match your plant's current development phase:

Target Growth Stage	Recommended Part A Dose	Recommended Part B Dose	Target Water Volume
Early Vegetative Phase	1ml – 2ml	1ml – 2ml	per 1 Litre of water
Peak Bloom / Flowering	3ml – 4ml	3ml – 4ml	per 1 Litre of water

Step-by-Step Usage Instructions:

1.Fill your reservoir with water:Tank Preparation.

Fill your active hydroponic reservoir or mixing tank with fresh water. Ensure your circulation pumps are running to create a consistent, steady water movement.

2.Add Part A and stir thoroughly:Component A Dilution.

Measure out your required dose of Hydro A (up to 4ml/L). Pour it directly into the water and allow it to mix completely throughout the reservoir. Never mix Part A and Part B together in their concentrated form.

3.Add Part B and mix again:Component B Dilution.

Measure out the exact same volume of Hydro B as you did for Part A. Add it to the moving water and stir the entire nutrient solution thoroughly for at least 10 seconds to ensure total homogenisation.

4.Check your final values:System Calibrations.

Use your calibrated digital meters to check the mix. Aim for a standard hydroponic pH sweet spot of 5.5–5.8 and confirm your target EC level is correct before opening the lines to your crop.
