Dool International was commissioned by System USA to raise a circa 3-acre greenhouse with 5 feet (from 9 to 14 feet) off of the ground. They went to work while the crop was still in and raised the greenhouse without needing to empty out the building. The greenhouse was raised for increased optimization and better growing conditions.
Humidity is a major issue in growing cannabis. By raising the greenhouse 5 feet there is an extra buffer area which creates a more stable climate, more cool and less humid. This allows the grower to more easily control the climate inside the greenhouse. The lower levels of humidity also serve to combat the emergence of mildew and various other molds.
After Dool International raised the greenhouse System USA renovated the old façade, replacing the acrylic with steel cladding. The renovation is a counter measure against break-ins.
This was not Vincent van den Dool’s first project at raising a cannabis greenhouse. He and his company have already raised 8 greenhouses in Salinas, California. The companies whose greenhouses have been raised have reported more stable climate conditions and lower levels of humidity.
This video shows the process of raising the greenhouse. Of course, it is speeded up a little bit to keep it short.
