Energy costs could be significantly reduced simply by prolonging the propagation, according to research conducted by Klimrek. Especially peppers proved interesting because of the longer time the crop needs for plant development.
After the plants arrive from the plant nursery, these are first placed at double density in one half of the greenhouse. After just 10 weeks, the plants are then spread. During this period, the energy savings reach up to 50%.
Pepper grower Jack Alblast, from Honselersdijk, has tested 13 week double density propagation without subsequent negative effects on the production. With 10 weeks, taking into account current gas prices, the savings already amount to 2.00 Euro per square metre.
Better climate at the start
In the winter months, the climate at the start of the cultivation stage can often hamper a healthy growth. The double density propagation allows for a faster and better microclimate. The screen can also be open earlier for extra light with limited energy costs.
Profitable lightning
To be able to grow peppers in the middle of winter, additional exposure to light is needed. This is easier to do on a smaller area, also with lower costs; this also further results in a more uniform and manageable crop.
Rising energy prices
An entrepreneur must consider both threats and opportunities. A sharp rise in energy prices, for example, is considered inevitable in the long term. With a gas price of 60 cents, a smart breeder/entrepreneur can save up to 5 Euro per square metre by adopting 'Prolonged propagation' compared to other companies.
For both new construction and existing greenhouses
In new greenhouses, the return on investment, according to research, is in three years. For existing greenhouses, provided they are high enough, the payback time is 4 to 5 years.
