Hydroponics
Hydroponics requires product- and crop-specific instructions. The watering dilution above is not a guide for a permanent nutrient solution. This calculator therefore does not calculate hydroponic doses, EC targets or top-up amounts for this fertiliser concentrate. Please discuss the product and your hydroponic system with our advisers.
Contact our advisers →Irrigation system / fertilizer injector
Dosing units, irrigation systems and fertilizer injectors need settings suitable for the product and equipment. Plant size alone cannot determine pump settings, running time or a stock solution.
- Establish the actual water flow and intended running time.
- Check injection ratio, suction and product suitability against the equipment and product instructions.
- Prepare a flow test with clean water according to the equipment instructions. Do not use the normal watering dilution as continuous injection without checking its suitability.

Mixing with other productsMixing, combining or applying separately
Using products as part of the same care routine is different from mixing them in one container. Follow the labels and application instructions of all products involved.
- Tank mixing: Combine products in a watering can or spray tank only when the manufacturer instructions confirm the specific combination and use. Do not mix undiluted concentrates together.
- Separate application: Applying products separately or at different times does not automatically establish compatibility. Check the species, location, plant condition and instructions for both products. No universal waiting period follows from this.
- Complementary products: A recommendation for suitable growing media, accessories or another care product does not mean that it may be mixed with the fertiliser.
- Plant protection products: The crop, target organism, application method and pack instructions must also be suitable. The fertiliser calculator does not calculate plant protection product quantities or confirm compatibility.
The recommendations cover products for different care tasks. Combining them in the same solution requires the instructions for both products to allow that combination. Otherwise, apply the products separately.
Plant protection products and application
Check the plant species, pest and location for each product. Use the current instructions for dosage, application rates and water volumes.
Combine fertilising and plant protection
For an explicitly confirmed mixing partner. Confirmation applies to each product individually.
- Prepare the fertiliser solution using the appropriate water volume and dosage.
- Use the selected plant protection product’s instructions to determine its dosage and application rate, then add it to the prepared fertiliser solution.
- Mix thoroughly and use for the specified watering or spray application.
The fertiliser calculator calculates fertiliser only. Its watering volumes and young plant or seedling adjustments do not apply to plant protection products.
Use plant protection products safely. Always read the label and product information before use.

The correct mixture
10 ml per 2.5 litres of water.
Two capfuls equal 10 ml. Use 12 ml concentrate for 3 litres of water. Match the amount of prepared solution to root space or leaf area and account for existing fertiliser.

Mix your fertiliser – step by step
Prepare the amount of nutrient solution you need. The dilution depends on this product and the required amount of water.
-
Clean the container
Clean the watering can, sprayer or bucket and rinse it with clean water.
-
Calculate the dose
Choose the amount of water you need and calculate the matching concentrate dose. The dosage calculator helps you do this.
Dilution: 10 ml per 2.5 litres of water
Calculate the right amount → -
Add some water
Pour part of the calculated amount of water into the container first.
-
Shake, open & measure
Shake the closed bottle well. Then open it and measure the calculated concentrate dose with the dosing cap. Measure more than once if needed.
A full dosing cap holds 5 ml. Use suitable millilitre graduations for smaller amounts.
-
Add the concentrate
Pour the measured concentrate into the water already in the container.
-
Add the remaining water & mix
Add the rest of the calculated water and mix thoroughly. Your diluted nutrient solution is ready.
Dosage and water choice
Shake well before use. Choose the volume of water and measure the calculated concentrate dose. Pack size does not change the dilution.
Preferably use low-lime water or rainwater at 15–25 °C. Add the measured concentrate to the water and mix thoroughly. Never apply undiluted; prepare only what you need.
When applying the solution
Check growth, growing-medium moisture and previous feeding. Feed only during active growth.
Regular application period: April–September
For root feeding, moisten dry growing medium with water first. Check drainage; the pot should not remain standing in water.
Distribute the diluted solution over the pre-moistened root zone or spray the foliage. Do not spray open flowers. Do not apply in direct sunlight, below 5 °C or above 30 °C. Do not inhale spray mist.
Follow the safety instructions →Through the root zone
Apply the diluted solution to the pre-moistened root ball. Allow excess water to drain from containers; account for initial and additional feeds.
Through the foliage
Wet foliage according to the label and avoid open flowers. A foliar feed counts towards total nutrition and is not automatically added to root feeding.
Enlarge image ↗
Feed roots and foliage
Choose the appropriate application method.
The label permits watering and spraying at the same dilution. Both routes count towards total nutrient supply. Avoid open flowers; a foliar feed is not an automatic extra portion.
Understand root and foliar uptake
Understanding plant feeding
How do nutrients get into a plant?
Through the roots or through the leaves: explore four steps to discover how a plant takes up and uses nutrients.
Select a point in the picture or choose a stage.
Stage 01 / 04
Water carries nutrients to the roots
Dilute the fertiliser with water according to the label. Watering carries this nutrient solution into the soil or growing medium around the roots.
Good to knowAlways dilute the concentrate and keep to the stated dosage.
A closer look
Watering carries dissolved nutrients into the growing medium around the roots. Contact with the absorbing root surfaces is the first step.
Stage 02 / 04
Roots take up dissolved nutrients
Fine root hairs increase contact with the growing medium. Tiny transport proteins in the membranes surrounding root cells help dissolved nutrients enter the cells.
Good to knowRoots take up nutrients; they do not simply absorb all the fertiliser along with the water.
A closer look
Root hairs increase the contact area. Transport proteins in cell membranes enable mineral ions to enter; water movement and nutrient uptake are distinct processes.
Stage 03 / 04
An inner layer controls the route
On their way into the root, nutrients meet a special layer of cells. It prevents substances from simply flowing through the gaps between cells and helps the plant control uptake.
Good to knowMore fertiliser does not automatically mean better nutrition.
A closer look
Nutrients move through the root tissues. The endodermis acts as a control layer: its barrier interrupts unrestricted movement along the cell walls.
Stage 04 / 04
Transport channels carry water and nutrients
Inside the root are fine transport channels called xylem. Water and absorbed nutrients can travel through them towards shoots and leaves.
Good to knowHealthy roots and suitable growing conditions are important for nutrient supply.
A closer look
After entering the vascular tissue, nutrients can travel with the water stream in the xylem towards the shoot. Uptake and nutrient supply also depend on root health and growing conditions.
View original diagram ↗GREEN24 diagram with German labels
Stage 01 / 04
Diluted solution is applied to the leaf
For foliar feeding, diluted nutrient solution is sprayed onto the leaves. The product instructions tell you whether it is suitable for this use and how much to apply.
Good to knowSpray only as directed by the product instructions, never with undiluted concentrate.
A closer look
Foliar feeding places diluted nutrient solution on the leaf surface. Wetting depends on factors including the leaf surface and the solution.
Stage 02 / 04
Nutrients must cross the protective surface
The leaf surface protects the plant. Dissolved nutrients can pass through this layer; tiny openings in the leaf may also play a part. Uptake varies with the type of leaf and the conditions.
Good to knowDifferent leaves do not absorb a nutrient solution equally well.
A closer look
Dissolved nutrients can pass through the protective cuticle; pathways involving stomata may also contribute. Their relative importance varies with plant species and conditions.
Stage 03 / 04
Cells inside the leaf take up nutrients
Behind the surface lies living leaf tissue. Its cells can take up nutrients that have crossed the surface and use them for their activities.
Good to knowA droplet on a leaf does not yet mean its nutrients have been absorbed.
A closer look
After crossing the surface, nutrients can be taken up by living leaf cells. The amount depends on factors including the nutrient, formulation and environmental conditions.
Stage 04 / 04
Nutrients are used in the leaf and may move onward
The plant can use absorbed nutrients within the leaf. Some can also reach other plant parts. This depends on the nutrient and the plant's condition.
Good to knowFoliar feeding does not mean every nutrient immediately reaches the whole plant.
A closer look
Absorbed nutrients can be used within the leaf. Whether and how far they move to other plant parts depends on the nutrient and the plant's condition.

Frequently asked questions
Questions before the next feed
How far do the packs go?
At the stated dilution, 250 ml makes 62.5 litres and the twin pack 125 litres of feed solution.
Why is my agapanthus not flowering?
Check light, winter conditions, dry spells and the roots. An oversized or excessively root-bound pot and heavy division can delay flowering.
Should all leaves be removed in autumn?
Only deciduous types lose their foliage. Keep healthy leaves on evergreen plants and gently remove yellow or dead ones.
When should I feed after repotting?
Account for fertiliser already present in the compost. Follow its advice on when to resume feeding and observe actual growth.
Should I spray the flowers?
No. The label excludes spraying open flowerheads. For foliar application, wet suitable leaf surfaces evenly.
