Plagron Hydro A & B is a highly concentrated two-part mineral fertiliser developed specifically for hydroponic growing on inert substrates. Its formula supplies all essential macro- and micronutrients in an easily absorbed chelated form, ensuring rapid uptake, healthy growth and abundant flowering throughout the plants' life cycle.
Plagron Hydro A & B is a professional two-part nutrient system designed for use during both vegetative growth and flowering. Separating the nutrients into two components prevents unwanted chemical reactions between calcium and phosphates, ensuring maximum stability and availability of the nutrient solution.
Hydro A is rich in calcium, which helps build strong cell walls, stimulates root development and supports plant resilience under temperature stress. Hydro B contains magnesium, an essential element for chlorophyll synthesis and efficient photosynthesis. Together, the two components provide complete nutrition throughout the development cycle.
Thanks to its high concentration (ratio 1:400), the product is highly economical. Just 1 litre of Hydro A and 1 litre of Hydro B are sufficient to prepare approximately 400 litres of nutrient solution. The nutrients are in a rapidly absorbed chelated form, allowing plants to develop optimally even at non-ideal pH or lower root-zone temperatures.
Hydro A & B is suitable for all inert substrates, including rockwool, expanded clay, perlite, Mapito and others, as well as Drain-to-Waste and recirculating hydroponic systems.

• Vegetable crops
• Flowers
• Ornamental plants
📋 Instructions for use
- Shake the bottles well before use.
- Add up to 2.5 ml of Hydro A per 1 litre of water.
- Once Hydro A has dissolved completely, add the same amount of Hydro B.
- Never mix the two concentrates directly with each other.
- Use the prepared nutrient solution at every watering.
- Maintain pH between 5.5 and 6.5 and adjust EC according to the plant development stage.
⚠️ Important: Always add Hydro A first, and Hydro B only after it has fully dissolved in water. Mixing the concentrates directly can lead to insoluble compounds forming and reduce fertiliser effectiveness.
💡 Tip from Urban Botaniks: For maximum results, combine Plagron Hydro A & B with Power Roots, Pure Zym, Green Sensation and Sugar Royal, following Plagron's official feeding schedule. This will support strong root-system development, improve nutrient uptake and increase crop yield and quality.

AzoLogic® is an innovative microbial inoculant from Terra Aquatica, developed to stimulate root-system development and improve nutrient uptake. It contains the beneficial bacterium Azospirillum sp., which colonises the rhizosphere and supports natural plant growth, rooting and nutrition processes. It is suitable for soil, coco, hydroponics and bioponic systems.
Terra Aquatica AzoLogic® is a new-generation biostimulant based on beneficial rhizosphere microorganisms (PGPR – Plant Growth-Promoting Rhizobacteria). Its main active ingredient is the bacterium Azospirillum sp., known for its ability to stimulate the formation of new roots, root hairs and secondary branches, leading to a stronger and more efficient root system.
Better-developed roots enable plants to absorb water, nitrogen, phosphorus and micronutrients from the substrate more efficiently. This leads to faster establishment after transplanting, stronger vegetative growth and better development throughout the plant’s life cycle.
AzoLogic® acts as a biological activator of soil and substrate, stimulating beneficial microbial activity around the roots. This improves biological fertility and increases plant resistance to various abiotic stress factors such as drought, temperature fluctuations, salt accumulation and post-transplant stress.
The product is suitable both for professional growers and hobbyists who want to improve root-system development naturally. The formula is compatible with both mineral and organic fertilisers and can be used throughout the growing cycle.

📋 Instructions for use
Recommended dosage:
✔️ 1 g per litre of nutrient solution
or
✔️ 1 kg/ha for field crops
Application is recommended at planting, transplanting and at key stages of plant development. For optimal results, Terra Aquatica recommends at least two applications per year – at the beginning of the crop and during active growth.
💡 Urban Botaniks tip: AzoLogic® works best when applied to moist soil or through the irrigation system. Combining it with organic fertilisers and active soil microflora leads to faster root development and more efficient nutrient uptake.

Green House Feeding CalMag is a high-quality water-soluble mineral fertiliser designed to prevent and correct calcium and magnesium deficiencies in all plant types. The formula contains nitrogen, calcium and magnesium in an easily absorbed form and is ideal for use with soft water, reverse-osmosis (RO) water, rainwater, as well as in hydroponic, coco and soil growing. Thanks to its high purity, the product contains no chlorine, sodium or heavy metals.
Green House Feeding CalMag is a professional mineral supplement developed to provide optimal amounts of calcium and magnesium – two vital elements for proper plant development. Calcium contributes to the formation of strong cell walls and stimulates the development of roots and new tissue, while magnesium is a key component of chlorophyll and plays a vital role in photosynthesis.
The product is particularly suitable when using reverse-osmosis (RO) water, rainwater or very soft water, where the natural calcium and magnesium content is insufficient. Adding CalMag restores the mineral balance and prevents typical symptoms such as interveinal chlorosis, necrotic spots, deformed leaves and stunted growth.
Thanks to its 100% water-soluble formula, nutrients become immediately available to plants. CalMag can be used through fertigation, hydroponic systems or foliar application, and is compatible with all main Green House Feeding mineral fertilisers – Hybrids, Short Flowering, Long Flowering and Booster – as well as nutrient programmes from other manufacturers.
Composition (EC fertiliser):
✔️ Total nitrogen (N): 13.5%
- Nitrate nitrogen (NO₃): 13.1%
- Ammoniacal nitrogen (NH₄): 0.4%
✔️ Calcium oxide (CaO): 16.7% (water-soluble)
✔️ Magnesium oxide (MgO): 6.0% (water-soluble)
✔️ EC at 1 g/L: 1.2 mS/cm
✔️ Does not contain:
- Chlorine
- Sodium
- Heavy metals
Benefits
✔️ Prevents and corrects calcium and magnesium deficiency
✔️ Suitable for reverse-osmosis (RO) water and rainwater
✔️ Improves cell-wall strength
✔️ Stimulates the development of a strong root system
✔️ Improves photosynthesis and chlorophyll formation
✔️ Supports the formation of healthy flowers and quality fruit
✔️ Ensures rapid absorption thanks to high solubility
✔️ Compatible with most mineral nutrition programmes
✔️ Can be used alone or with fertilisers from other manufacturers
✔️ Contains no chlorine, sodium or heavy metals
Application
Suitable for:
• Vegetable crops
• Fruit trees
• Flowers
• Ornamental plants
• Hydroponic systems
• Coco substrates
• Soil growing
• Fertigation
• Foliar feeding
• Professional and hobby growing
📋 Instructions for use
Base dosage
✔️ 0.1 – 0.5 g per 1 litre of water
For soft water (RO / rainwater)
✔️ 0.5 g/L water (about 0.6 EC)
For hard water or rich soil
✔️ 0.2 g/L, 1–2 times per week (as needed)
Foliar application
✔️ 0.2 g/L, every 10 days, only in the event of confirmed calcium or magnesium deficiency.
For automatic dosing systems
✔️ Preparation of concentrate: 10–15 kg product per 100 litres of water for systems such as Dosatron, Netafim and others.
⚠️ Important
- Do not mix Green House Feeding CalMag with other calcium supplements.
- When using the Green House Feeding programme, you can stop using CalMag around the 6th week of flowering and switch to GHF Calcium Chelate if you wish to continue supplying calcium without additional nitrogen.
💡 Tip from Urban Botaniks: If you use a reverse-osmosis (RO) system, Green House Feeding CalMag should be the first addition to the water before the other fertilisers. This will restore the required calcium and magnesium content and provide an optimal environment for the absorption of all other nutrients. 🌱
‘Fertilisers and Additives’ covers organic and mineral N-P-K formulas, secondary macronutrients (Ca, Mg, S), micronutrients (Fe, Mn, Zn and others) and specialised additives such as Ca/Mg, chelates, silicon, humic/fulvic acids and enzymes—for stable growth, flowering and high stress tolerance. N-P-K are the primary macronutrients; Ca, Mg and S are secondary macronutrients; micronutrients are needed in small doses but are critical to metabolism.
