Our Idea

 

Hydroponic systems technically make it possible to grow plants without the use of substrates. 

So why do we still use them?

With the Hydrostarter we have developed a cultivation system that enables you to produce bare-root seedlings without any substrate.

 


JUST WATER

No soil, no substrate. To grow plants in the Hydrostarter, only water and light are needed.

PURE ROOTS 

Without the need for artificial or natural substrates, the Hydrostarter grows bare-root seedlings which are perfectly suited for further hydroponic cultivation


ZERO WASTE 

Only the pure plant is harvested - without any rooted substrate. Hydrostarter and plant can be separated very easily and the device is reusable.

Our Motivation 

 

Aquaponic and hydroponic cultivation are concepts for sustainable food production based on the idea of a circular economy. The resource savings are already impressive. However, substrates are still used to grow plants from seeds and in some cases this involves enormous environmental pollution (e.g. peat, rock wool). For this reason, we have developed the Hydrostarter, a hydroponic cultivation system that makes it possible to produce bare-root seedlings without any detours.

So compatible

 

When the seedlings are large enough, they can be transplanted into another medium, or transferred into a hydroponic system together with the Hydrostarter.

Sustainability

 

Unlike substrate, the Hydrostarter can be reused. 

Aquaponics and hydroponics become part of the circular economy.

 Comfort

 

The reservoir is large enough to provide the young plants with water for days and even weeks.

Handling substrate is completely eliminated.

Flexibility

 

The Hydrostarter can be used to grow various plants (e.g. lettuce, basil, pak choi).

The bare-root seedlings are suitable for any hydroponic system.
