This set suits aquarists with planted tanks of 100–150 litres whose substrate has become inert or has lost its nutrient content over time. The balls are placed directly in the substrate, so nutrients are released where the roots can reach them, without relying on feeding the water column.
Why it matters
- Root-zone feeding: each ball is positioned in the substrate and releases its contents close to the roots, where plants take up most of their nutrients.
- Full nutrient profile: the composition includes NPK and micronutrients to support healthy growth.
- Titanium biostimulator: the formula contains titanium, which is described as supporting plant metabolism, nutrient uptake and root development.
- Practical dosing: the balls are handmade, and roots often wrap around them to draw nutrients directly from the ball.

Frequently asked questions
The set of 15 balls is dedicated to aquariums of 100 to 150 litres. Each ball is about 2 cm in diameter and is handmade.
Yes, the balls can be placed in the substrate of humid tropical terrariums. They provide roots with a stable, long-lasting source of nutrients.
The balls contain a full NPK set and micronutrients. They also include a titanium-based biostimulator, which is said to support plant metabolism and the uptake of nutrients.
The balls should be placed in the substrate, where they are not washed out by water flow. They release nutrients slowly right where the roots can reach them.
The balls are described as a good solution for aquariums with inert substrate, such as river gravel, or with substrate that has lost its properties over time. The manufacturer notes that plants often do not need additional fertilization of the water because the release of nutrients is large but slow.
