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.

Yellow leaves,
slow growth,
or constant stress?
Your plant looked great just a few days ago, and suddenly...
Why does it have yellow leaves? And they’re drooping pretty badly, too...
You water it. You fertilize it. You Google it... “What’s wrong with my plant?”
And honestly? Most of the time, the problem isn’t above ground. It’s below—in the soil.
Because that’s exactly where it’s decided whether your plant grows or slowly gives up.
That’s exactly where Green Bull comes in. Not as a traditional fertilizer. But as a signal transmitter.
A system of natural plant hormones and microbial impulses that brings your plant back into balance.
You’re not just supporting the plant itself—you’re activating what actually makes it strong: its environment.
Whether it’s coconut coir, living soil, a drip system, or traditional potting soil—Green Bull integrates seamlessly into your setup.
And your plant? It’ll show you pretty quickly that it’s got the hang of it.

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.
Easy to use.
Powerful effect.
Add 100 ml of Green Bull® to 5 litres of water.
For 10 litres of watering water, mix in 200 ml of Green Bull®.

One product
for all plants,
everywhere.
365 days of plant power, indoors & outdoors.
Whether tomatoes, monstera, or lemon trees, Green Bull® works indoors all year round.
Can be used outdoors at outdoor temperatures above 8°C.
Inspired by nature.
Optimized by science.
Plants cannot run away – so they defend themselves with signaling substances.
Alganize uses this principle. Microalgae are used to cultivate plant-like metabolic products which are obtained through targeted induction.
These strengthen the plant from within – for greater resilience, splendor, and longevity.
