New deep float system: lower cost, higher yield
Reading time: min.
At Meteor Systems, we continuously innovate our cultivation systems. In collaboration with ErfGoed, we have been testing a new deep-float system since June that optimally utilizes water, air, and energy. The first results are promising: stronger crop growth, lower costs, and a more stable growing climate with reduced energy use.
Innovative system
The system’s design is simple yet ingenious. Beneath the floating rafts lies a patented cultivation floor with both water and air supply. Several times a day, the crop receives water through this floor, after which air is blown through the same lines. This keeps the microclimate in motion, and CO₂ can also be supplied via the same channels.
We use floats with an X-shaped planting hole and small supports, ensuring the raft stays above the surface. The X-shape allows air and CO₂ to flow along the growing medium toward the root zone, creating a stable microclimate.
“The airflow is now evenly distributed,” says Peter Lexmond. “That results in consistent quality, longer shelf life, and higher productivity.”
Stronger crops and energy savings
Active aeration ensures controlled evaporation, resulting in stronger crops. Roots develop well without becoming excessive. “The airflow dries the roots outside the plug, preventing fungal growth,” adds Bas Dirven.
Another advantage is energy efficiency: greenhouse temperature can be reduced by 1.5 to 2°C. “The warmth is added from below, exactly where the plant needs it. It’s inefficient to heat the entire space when the crop itself is what matters,” he explains.
Clean, stable, and fungus-free
The floats require little water, and the substrate rock in the floor maintains a stable microbial balance. “The combination of air, water, and rock is self-cleaning,” explains the ErfGoed team. “The water remains in motion and oxygen-rich, minimizing the need for disinfection.”
Since the start of the trials in June 2025, no crop protection agents have been needed — perfectly in line with the growing demand for sustainable cultivation.
A more balanced climate
According to cultivation expert Peter Klapwijk, the airflow not only prevents fungal diseases but also creates a more balanced temperature and humidity distribution. “Plants transpire more efficiently, achieving the same growth rate with less heat.”
This leads to lower energy consumption, a more stable climate, and fewer temperature differences between crop layers.
Production results
Early results are promising: approximately 3.5 kg of lettuce per m² per 28-day growing cycle (14 days germination, 14 days cultivation), equivalent to 85 kg per m² per year.
