10 reasons why more and more plant lovers throw out the blue fertilizer and use this instead.
What professional nurseries have used for decades: the three specific actives any technician would tell you about if you knew them. And why, in the store, they sell you something else.
If any of these sound familiar, keep reading:
- You've been adding blue fertilizer for months and your pothos still looks exactly the same.
- You try the home tricks from TikTok (eggshell, yeast, banana) and notice nothing.
- You cut a monstera cutting that cost you money. And it rotted before it rooted.
- Your soil is hard and cracked. The water sits on top, it doesn't soak in.
- You killed the plant that someone special gave you. And you still remember it.
Why blue fertilizer doesn't work the way you were told
Supermarket fertilizer is NPK salts dissolved in water. They provide macronutrients, yes. But the plant needs three more things to use them: a living substrate to hold them, roots able to absorb them, and energy to process them.
If your soil is dead, your roots weak or the plant exhausted, adding more NPK is like giving pasta to a dehydrated athlete: the body can't take it in.
"In any professional nursery we use three separate products: a rooting agent for everyday use, a concentrated rooting hormone for difficult cuttings, and a microbial soil activator. If you only know NPK, you've missed 70% of the work."

The three actives every nursery uses (and that are hidden from you)
It's not magic or a monks' secret. They are three identified compounds, with a measurable effect, that every propagation technician knows.
Stabilized auxins
The hormone the plant uses to differentiate tissue into roots. Applied from outside, the cutting doesn't have to produce it: it receives it. It roots 4-5 times faster and with a high success rate.
Concentrated rooting hormone
The pure hormone for when you really want to propagate. No filler nutrients — just the active that triggers the cell explosion that generates roots. For difficult cuttings where Roots isn't enough.
Substrate probiotic
Humic acids + live bacteria (Bacillus, Trichoderma) + potassium. Restores the substrate's microbiome so the soil can absorb, retain and release nutrients again.
For the first time, all three in your home
Until now, getting these products meant ordering them in the professional 5 L format from an agricultural distributor. Brotika is the first brand to bring them to home use, with the same active quality and exact dosing.
Three small bottles. One function each. No green marketing, no dyes, no fragrances: just the active at its correct concentration.
Brotika Roots
Rooting hormone. Cuttings in 5-9 days.
From €19.99
Brotika Boost
Pure hormone. Difficult cuttings in 7-14 days.
From €19.99
Brotika Soil
Substrate probiotic. Microbiome in 30 days.
From €24.9910 concrete reasons why it works
They're not promises: they're the points that set a technical-use active apart from a supermarket fertilizer.
Identified actives, not secret formulas
Each bottle states what it contains and in what proportion. No "patented complex", no names that hide ingredients.
Professional concentration, home format
Roots contains 0.2% auxins — the same concentration used in nurseries. It's not a diluted "home" version.
Exact dose, already measured
20 drops per 500 ml. 1 teaspoon per pot. Dropper and spoon built in. No scale or measuring cylinders.
Live bacteria, not marketing
Soil contains 100 million viable spores per gram of Bacillus and Trichoderma. As a powder they keep; when watered they activate.
Roots: rooting agent and nutrition in one bottle
Roots is a 2-in-1: it helps the cutting take hold and gives a nutrient boost. Your everyday product.
Measurable timelines, not vague promises
Roots: roots in 5-9 days. Boost: difficult cuttings in 7-14 days. Soil: fluffy substrate in 30 days.
No fillers, no dyes, no fragrance
The red of Roots and the yellow of Boost come from the active itself, not from added dye.
Roots: several ways to use it
Dipping the cutting, root watering or growing in water. One bottle, several ways depending on the plant.
Combinable as a system
Soil prepares the substrate, Roots handles the everyday, Boost propagates the difficult cuttings. Alone they work; together they're a system.
30-day no-questions guarantee
One month to try it. If you see no difference, we refund every euro via WhatsApp. No forms.
Three bottles. Three different routines.
Each one has an exact dose and a moment of use. No scale, no complicated instructions.
Roots · cutting
20 drops in 500 ml of water. Submerge the base of the cutting for 20-30 seconds. Move to substrate. Visible roots between day 5 and 9.
Boost · difficult cutting
20 drops in 500 ml of water. Submerge the base of the cutting for 20-30 minutes. Move to substrate. Visible roots in 7-14 days.
Soil · monthly
1 teaspoon per pot every 30 days. Sprinkled or dissolved. Fluffy substrate in 30 days.
Before and after from customers
Photos sent in by real buyers. No filters, no retouching. What happens when a plant gets back what it needs.
What those who already use it say
Out of five pothos cuttings following the bottle's dose, four took. Before, one if lucky. The exact dose changes the result.

The soil in my pots was concrete. One application of Soil and a month later: earthworms, soft, a different thing.

I combined Soil in the substrate and Roots in the watering. My monstera went from 2 to 7 leaves in two months.

I use Roots every week when watering my indoor plants. Stronger and with better color.

What you ask us
How long until I see the change in my plant?
It depends on the active: Roots gives visible roots in 5-9 days, Boost triggers roots on difficult cuttings in 7-14 days, and Soil needs 30 days to change the substrate's texture.
Is it safe for my pets and children?
They are products for home use. Even so, keep them out of reach of children and pets and do not ingest them, like any gardening product.
Does it work on any plant?
Yes. The three actives work for indoor plants, outdoor plants, cuttings and the vegetable garden. The PDF guide includes the dose per plant type.
Why is Soil a powder and the others liquid?
Soil's bacteria stay alive as spores in dry powder. In liquid it would have to be pasteurized and they would die. When watered, they activate.
Do you ship to my country?
Yes, we ship worldwide. Shipping of €5 and free from €35, with estimated delivery in about 5 days.
How long does each bottle last?
Roots: 50 ml for 100+ applications. Boost: 50 ml of concentrated hormone. Soil: 100 g for about 6 months of use.
And if it doesn't work?
You have 30 days. If you don't notice the difference, message us on WhatsApp and we refund every euro. No questions.
