Your plants will grow strong, naturally and sustainably. 🌍
The soil is pre-fertilised, making it easy to get started in the first 3 weeks. In addition to compost and perlite, the soil contains a specially developed, biologically active premix. This long-tested combination ensures the supply of nutrients for a long period of time.
Our Bonsanto® organic soil provides your plants with the perfect basis for healthy and vigorous growth. The mixture consists of high-quality, pre-fertilised peat, finely balanced coconut substrate and natural perlite for optimum aeration and water absorption.
Advantages of Bonsanto® organic soil:
-
Pre-fertilised for 2-3 weeks - Ideal for the germination and growth phase without additional fertilisation
-
High water storage capacity - Even moisture distribution, less watering required
-
Optimum air permeability - Prevents waterlogging & root rot
-
Stable pH and EC values - For controlled nutrient absorption
-
Suitable for all Bonsanto grow systems - Especially in combination with Bonsanto fertilisers such as Organic Boost or Extreme Energy
Recommended for: Chillies, herbs, salads and many other types of indoor plants. Also ideal for beginners thanks to the forgiving structure and nutrient buffering.
The soil is supplied in 6.5 litre bags and can therefore be filled easily and without leaving any dirt behind. By the way: A 6.5 litre bag is the perfect amount to fill a container in the Mini Grow Box.
Tip: Before you place your plant in this soil, it should be moistened about 36 hours beforehand. This will allow the microorganisms to start working.
Important: Only a dry soil is able to absorb oxygen for your plant. It is therefore not only useful, but necessary to let the soil dry out completely on a regular basis to ensure healthy growth of your plant.
The soil is of course also suitable for autoflowering plants.

Absolutely top soil, my plants like it! It's not cheap, but you don't need that much for the Bonsanto mini grow boxes. About 1.5 bags are enough for one run with two 3.2 litre pots.

I have used the Bonsanto® pre-fertilised premium soil and my plants are thriving. It is well aerated, retains moisture and the pre-fertilised mix gives the plants a strong start. Highly recommended!

The larger 4-pack format is practical, I don't need to buy more as often. Top quality, the soil remains loose and permeable, yet rich in nutrients. A clear recommendation for anyone who values healthy plants.

The soil is generally of good quality and appears to be very rich in nutrients. However, the bag was partially lumpy and a little damp when I opened it, so I had to sieve it first. The price is also quite high compared to normal soil. Plants grow well, but for me it's not an all-round perfect product.

I was pleasantly surprised - the soil smells pleasantly fresh and not artificial. My plants really took off after repotting. Finally a soil that makes you realise it's really natural.

At last, soil that delivers what it promises. I particularly like the strong organic pre-fertilisation - my plants develop much better than with normal DIY store soil.

The premium soil makes a good impression overall and my plants are growing well in it. However, the bag was slightly damaged when it arrived and some of the soil had already dried out. To be honest, I had expected a little more for the price, even though the quality is basically good.
Marcel -
I use the soil for my herbs on the balcony. They have become visibly stronger in just a few days. It's great that it's so rich in nutrients and doesn't need any chemicals at all

Very clean soil, no larvae, no foreign matter. You can see straight away that the quality is right. The plants absorb the nutrients very well and you have to fertilise much less.
