Ingredients
Antioxidants, polyphenols, spirulina signaling substances, chlorella signaling substances, laminaria,Mn 20 mg/L, Zn 15 mg/L, Cu 10 mg/L, Mo 1 mg/L, Fe 20 mg/L, B 10 mg/L
Important instructions
When using living soil or in combination with other boosters, the dosage should be reduced to 10 ml per litre of water (half dosage).
Application
Using Green Bull is straightforward and can be easily incorporated into your existing plant care routine. Before use, give the bottle a good shake to ensure all the ingredients are evenly distributed. Then mix approximately 20 ml of Green Bull with 1 litre of water. Simply add this solution when watering – ideally once a week. This ensures the natural signalling substances reach the root zone directly, where they can take effect. Whether indoors or outdoors: the application remains the same and adapts flexibly to your setup.

How did Green Bull® come about?
In 2018, Nils, an agricultural scientist with a passion for sustainable farming, travelled to India with his friend Amit. There, he witnessed how depleted soils destroy entire livelihoods – an experience that left a deep impression on him and laid the foundation for our current mission: to heal soils and rethink agriculture.
Together with Omar, a biotechnologist specialising in applied microbiology, and Karl, an entrepreneur and supporter from the very beginning, this led to the creation of Alganize – a company that uses microalgae to regenerate soils and make agriculture more resilient.
With Green Bull®, we are now bringing this research to your home. Our home product is based on the same biotechnological innovation that helps farmers worldwide revitalise their soils.
With every application, you are not only supporting your plants, but also our greater mission: the regeneration of soils worldwide and a more sustainable future for all.
Together, we are allowing healthy soils – and with them, life – to grow again.
Our values
We embarked on this journey to make soil and agriculture sustainable for the future. This must be done in harmony with nature, while never losing sight of our responsibility to feed the world's population. Soils around the world are facing major challenges – from advancing desertification and potato diseases to soil erosion. Green Bull® learns from nature and fights for healthy soils and nutrient-rich food.
Frequently asked questions
Green Bull® is applied via irrigation water or as a foliar spray. Standard: 20 ml per liter of water, once per week. For living soil or highly active substrates we recommend 10 ml/L for the first applications.
Yes. Green Bull® can be used from seedling to flowering. Lower dosages are often preferred in early stages.
Yes. Green Bull® is fully compatible with mineral fertilizers. By activating the soil microbiome, minerals can become more available and better absorbed. For young plants we recommend half dosage (10 ml/L).
Yes. These combinations can be synergistic. We recommend half dosage in such systems.
Yes. Green Bull® supports and activates existing microorganisms and works very well in living soil systems.
Yes. Dosage: 20 ml per liter of water, once per week.
Yes. Green Bull® is compatible with coco, hydroponics and automated systems.
No. Cool storage is fine. Protect from freezing.
Sometimes a microbial biofilm may form. This is harmless. Shake well or remove before use.
Many users notice effects within a few days. Best results develop over continuous use.
Green Bull® does not change genetics. By supporting metabolism and root activity, plants can reach their genetic potential more efficiently.
Yes, the signalling substances in Alganize technology support all plant cycles – whether indoor plants, vegetables or balcony flowers.
Green Bull® is a company owned by Alganize, specialising in the private customer sector.
Alganize GmbH develops biotechnological processes to reduce the use of chemical fertilisers and pesticides for food crops and sports turf.

No, even though it is made from microalgae. Green Bull® is not for drinking – it is for your plants.
Green Bull® contains naturally produced signalling substances such as polyphenols and antioxidants, as well as beneficial bacteria.
These strengthen the plant from within – comparable to a probiotic for humans.
No, we haven't managed that yet.
However, there can be many reasons why a plant dies – Green Bull® is not a miracle cure. Be careful not to water too often, as this is one of the most common reasons why plants die. Place them in a suitable location. You can find more tips on plant care on Instagram. https://www.instagram.com/greenbull.green/
Yes, Green Bull® can be mixed with other fertilisers.
In fact, it helps the plant to absorb nutrients better – especially during the germination phase of cannabis and tomatoes.
Note: When using Living Soil or in combination with other boosters, the dosage should be reduced to 10 ml per litre of water (half dosage).
No, Green Bull® is not a fertiliser, but a plant fortifier.
It stimulates the formation of fine roots, improves nutrient uptake and increases photosynthetic performance. This means more new leaves – and a bigger harvest. And much less fertiliser.
The signalling substances in Green Bull® are 100% natural.
Yes, but the organic certification takes a little longer, as the certification process involves checking whether the entire production process complies with organic guidelines.
Be careful not to water too often, as this is one of the most common reasons why plants die. If the plant is overwatered, even Green Bull® cannot help.
This video illustrates the approach behind Alganize: microalgae are specifically activated to release natural signalling compounds that stimulate soil life and support plant growth.
The focus is not on the direct supply of nutrients, but on the system behind it – the interaction between roots, microorganisms and biological processes.
These principles also form the basis for Green Bull and its use in home gardens and indoor settings.
In this podcast episode, Omar Khalaf discusses a key factor in healthy plant growth: stress reduction.
Rather than using more fertiliser, the aim is to support the plant so that it can redirect its energy towards growth, root development and stable development.
The approach is based on natural signalling substances and demonstrates why many problems are not caused by deficiencies, but by disrupted processes within the system.













Reviews
Wir konnten mit GreenBull unseren Buchsbäumen nach den Zünzler Attacken sichtbar was gutes tun. Mit einem Pfandsystem für die Flaschen gibt es sofort 5 Sterne
Grew many juicy tomatoes with it! I was kinda impressed by how much growth I have seen when combining a big pot plus Green Bull
Ich find es super geht gut bisher keine Probleme und super Wachstum
I have grown massive buds last year with the help of Green Bull. So happy! Also, none of my seedlings died, because I watered them with green bull in the very beginning.
Sie strahlen wirklich von oben bis unten. Toller Booster für deine Pflanzen. Ich bin echt davon überzeugt das es nochmal was rausholen wird!
