The critical moment, when nearly all stored CO2 has been consumed during daytime, can easily be detected with the sensor, as the photosynthesis-efficiency will decrease sharply.<\/p>\n\n\n\n<p>These effects are illustrated In the following graphs. Graph 1 shows that extra light given around 12:00 has no effect on efficiency, because there is still enough CO2 available to be consumed. Graph 2 shows that extra light given at the end of the day has a strong negative effect on photosynthesis, because all CO2 has already been consumed. The extra light results in stress and internal damage, and even in lower photosynthesis the next day<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img fetchpriority=\"high\" decoding=\"async\" width=\"602\" height=\"370\" src=\"https:\/\/https:\/\/sendot.nl\/wp-content\/uploads\/2020\/12\/phal01.png\" alt=\"\" class=\"wp-image-1320\" srcset=\"https:\/\/sendot.nl\/wp-content\/uploads\/2020\/12\/phal01.png 602w, https:\/\/sendot.nl\/wp-content\/uploads\/2020\/12\/phal01-300x184.png 300w\" sizes=\"(max-width: 602px) 100vw, 602px\" \/><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" width=\"591\" height=\"368\" src=\"https:\/\/https:\/\/sendot.nl\/wp-content\/uploads\/2020\/12\/phal02.png\" alt=\"\" class=\"wp-image-1321\" srcset=\"https:\/\/sendot.nl\/wp-content\/uploads\/2020\/12\/phal02.png 591w, https:\/\/sendot.nl\/wp-content\/uploads\/2020\/12\/phal02-300x187.png 300w\" sizes=\"(max-width: 591px) 100vw, 591px\" \/><\/figure>","protected":false},"excerpt":{"rendered":"<p>Bij de phalaenopsis teelt is gedurende de nacht opgeslagen CO2 een belangrijk factor in de belichting de volgende dag.
