Sonnenerde Organic Hemp Soil 20L – Peat-Free Living Soil based on Terra Preta (Ready to Grow)
The Sonnenerde Organic Hemp Soil 20 Liters is a Living Soil specialty soil that functions like a small ecosystem in the pot: microorganisms, fungi, and soil life help the plant to make nutrients continuously available – without you having to constantly re-fertilize. The result is a pleasantly simple setup for Urban Gardening, medicinal plants, and demanding potted crops, where you focus on stable results instead of corrections.
-
Peat-free – made from regional raw materials
-
Free from perlite & coir – real "soil" with structure and buffer
-
Ready-to-grow: supplies plants throughout vegetation, flowering, and fruiting phases
-
Active soil life (microorganisms, fungi, micro-organisms) for natural nutrient dynamics
-
Buffer effect – better compensates for daily fluctuations
-
Reduced water consumption with stable supply
What makes the Organic Hemp Soil special?
The recipe is based on Terra Preta and relies on a combination of composted plant material, organic biochar, wood fiber, expanded clay granules, and horn meal. This gives you a substrate that holds water, brings air to the roots, and slowly and controllably releases nutrients – exactly what many seek in potted cultures when they don't want to react "every minute."
Practical tip: A white fungal mycelium in the substrate can occur – this is not unusual for organic, living soils around horn meal and is usually a sign that something is working in the soil. The main thing is: do not overwater and ensure air exchange.
Suitable for
- Pot, planter, Smartpot / fabric pot
- Greenhouse & balcony (Urban Gardening)
- Medicinal plants, herbs, vegetables, ornamental plants and robust potted crops
Application (short & practical)
- Fill pot, plant, water thoroughly once.
- Then keep evenly moist – not continuously wet.
- As a rule: no constant re-fertilization necessary. Less is often more here.
Tips & Tricks: How to get the most out of it
-
Watering with care: Living Soil likes consistency. Rather soak thoroughly and then let it dry out again, instead of "a little" every day.
-
Fabric pots/Smartpots are a real sweet spot: more oxygen at the roots, more stable root climate.
-
Irrigation systems can work great if they don't "overwater." For suitable solutions: Irrigation at Vetter Grow.
-
Don't forget the climate: Good soil can buffer a lot – but without air exchange, it becomes difficult. If you work indoors, a stable environment (tent/box) helps: Grow tents & Grow boxes.
-
Reuse instead of discarding: After cultivation, organic soil can often be "refreshed" (e.g., with compost/topdressing) – saves money and raw materials.

FAQ – frequently asked questions about Sonnenerde Organic Hemp Soil
Do I need to fertilize additionally?
The Organic Hemp Soil is designed as a "ready to grow" soil that provides plants with nutrients and trace elements throughout the entire phase. In practice, this means: good watering management is usually sufficient – without constant re-fertilization.
Why is a white coating/fungal mycelium sometimes normal?
Organic components (e.g., horn meal) are slowly broken down by fungi and microorganisms. A white fungal mycelium is not automatically a problem. It is crucial that the soil is not constantly wet and receives sufficient air.
Is the soil suitable for balcony & urban gardening?
Yes – that's exactly what it's often used for: pots, containers, fabric pots, or greenhouses. Its buffering effect makes it pleasantly forgiving in everyday use.
Can I use the soil for young plants?
This works well for many robust crops. If you have very delicate seedlings, optionally start them in a milder substrate and then transplant them into the Organic Hemp Soil – this makes the start particularly relaxed.
For which systems is Living Soil not intended?
This soil is not designed for pure hydro setups (e.g., DWC/Aero). It plays to its strengths in potted cultures – where soil life can work.
