GHE Flora Duo Grow S/W 10L. is part of the highly concentrated two-component GHE DualPart fertiliser for growing in soil, hydroponics or coconut substrate. Only two bottles – Grow and Bloom – are all your plants need from the beginning to the end of the harvest. With DualPart, start with equal amounts of Grow and Bloom during rooting or early development; during vegetative growth, use more Grow than Bloom, and during flowering and fruiting, use more Bloom than Grow. It's that simple!
- for use with reverse-osmosis water
- DualPart uses several mineral forms, so your plants always have access to the elements they need in the correct form during growth and flowering.
- The formula includes bioactivators that improve overall plant health, resistance to pathogens and nutrient uptake.
How to use DualPart:
- Shake the bottles well before each use!
- Add each part separately, always stirring well afterwards!
- If using one measuring cup/jug, rinse it well before adding the next part and after use!
- For precise dosing of the two-part fertiliser, you can see here!
Use GHE DualPart with:
- Works well with all plants and substrates, hydroponics, soil or outdoor growing.
- Fulvic is the best and highest-quality fulvic acid on the market, which we recommend for further increasing and improving the harvest, in addition to the main nutrient fertilisers.
- TrikoLogic provides beneficial micro-organisms in the root zone, TrikoLogic S adds increased protection and additional performance, especially at high temperatures.
- FlashClean optimises the health/condition of the substrate and mineral availability, even with an already good harvest.
- FinalPart use on its own during the final 10 days to increase flowers.

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.

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. 🌱
