Did you know that the taller a greenhouse, the more energy efficient it is?
The reason being, in taller greenhouses, there is more growing space. A contributing factor to this is that there is less humidity than in lower glass houses. Therefore, we don’t need to put as much energy into taller glass houses because we don’t need to open the vents as much to control the humidity. Having the vents open less often means that we can keep the CO2 levels higher which is better for the crop and allows it to grow in a more efficient way.
