There is a saying in real estate business: the three most important success factors are location, location and location. In vertical farming, those three factors are climate, climate and climate. Why climate is so important?
Each plant and plant variety have a biological optimum performance level. In order to reach that, every part of the growing environment must be optimal – and climate is the key factor in this.
However, climate is a complex phenomenon: Optimal temperature, humidity and CO2 levels are dependent on each other. There isn’t only one perfect growing temperature, it depends on humidity and vice versa. Successful lighting is also dependent on successful climate. Even the best possible lighting level and spectrum are useless, if they don’t fit the climate conditions.
Successful climate control has multiple benefits
The line between the best possible climate and a failed climate is very thin. Plants may stop breathing and taking nutrition even within one degree of change in temperature or one percent of change in humidity. In addition, if you think that a good greenhouse climate control fits into vertical farming as well – guess again. In greenhouses the climate control is a totally different system than in vertical farming, which operates in an isolated space.
Thus, climate in vertical farming needs to be built with high quality technology and know-how of optimal climate recipes for each plant. Only with well working climate control, vertical farm can reach its full potential both in crop harvesting amounts and quality.
There are other elements to consider as well. Successful climate control will save water and enables re-circulation of extra heat produced by the growing lighting. This can lead to massive energy savings, as the same energy used in growing can be used elsewhere, and almost zero energy is required to grow the plants.
