Did you know flue gases from a boiler are not, by definition, purer than those from a CHF? Not many people do. It is, therefore, a good idea to map greenhouse gases. Glitch is an Interreg project. It studies and stimulates innovations in the glasshouse horticultural sector. It also calls on farmers in this sector to have their businesses mapped.
Dosing with CO2 in greenhouses has been common practice in vegetable cultivation under glass. This has been the case for many years. This source of carbon dioxide is a crucial element for smooth photosynthesis. This, in turn, build up organic mass. Most of the dosed CO2 comes from flue gases. A boiler or CHF can produce these.
Practical experience, however, shows that these flue gases are often lacking in quality. These flue gasses contain harmful gasses. Gasses such as NOx and ethylene are present along with CO2. These gasses are known to cause damage to crops.
Together, these issues are brought to light
Several companies were monitored last winter and new insights gained. For example, flue gasses from a boiler are not, by definition, purer than those from a CHF. The Glitch project can map this.
Glitch offers the chance to map different gases in a greenhouse. Specifically-designed sensors take these readings. Advice is given and regulation for better air quality is formed together with the grower. This ensures more efficient CO2 dosing.
