Plagron Hydro A & B 5l. – Two-component mineral fertilizer for hydroponics

Plagron Hydro A & B is a professional two-component nutrient system designed for use in both the growth and flowering phases. The separation of the nutrients into two separate components prevents unwanted chemical reactions between calcium and phosphates, ensuring maximum stability and digestibility of the nutrient solution.

Hydro A is rich in calcium, which is involved in the construction of strong cell walls, stimulates root development and supports plant resistance to temperature stress. Hydro B contains magnesium - an essential element for the synthesis of chlorophyll and the efficient course of photosynthesis. In combination, the two components provide complete nutrition throughout the entire development cycle.

Thanks to the high concentration (ratio 1:400 ), the product is very economical. Only 1 liter of Hydro A and 1 liter of Hydro B are sufficient to prepare approximately 400 liters of nutrient solution . The nutrients are in a quickly absorbable chelate form, which allows plants to develop optimally even at non-ideal pH or lower root zone temperatures.

Hydro A & B is suitable for all inert substrates such as rock wool, expanded clay, perlite, Mapito and others, as well as for Drain-to-Waste and recirculating hydroponic systems.

📋 Method of use

1. Shake bottles well before use.
2. Add up to 2.5 ml of Hydro A per 1 liter of water .
3. Once Hydro A has completely dissolved, add the same amount of Hydro B.
4. Never mix the two concentrates directly with each other.
5. Use the resulting nutrient solution with each watering.
6. Maintain pH between 5.5 and 6.5 and adjust EC according to the plant development phase.

⚠️ Important: Always add Hydro A first , and Hydro B only after it is completely dissolved in the water. Mixing the concentrates directly can lead to the formation of insoluble compounds and reduce the effectiveness of the fertilizer.

💡 Tip from Urban Botaniks: For maximum results, combine Plagron Hydro A & B with Power Roots , Pure Zym , Green Sensation and Sugar Royal supplements, following Plagron's official feeding schedule. This will help develop a strong root system, improve nutrient absorption and increase yield and quality of the crop.
