The cannabis plant originated in Central Asia and it grows wild in many tropical and humid parts of the world. In order to imitate these ideal growing conditions, cannabis needs to grow under strict humidification control and requires a completely climate-controlled environment to succeed.
How much humidity does cannabis need?
The required humidity level of Cannabis depends on the growing stage, but generally lies between 40-70%. If the humidity level is too low, the cannabis plants will transpire the water it needs to grow and flourish. This can lead to slow growth, small plants, dryness, or even cause the plants to litter.
On the other hand, a humidity level above limits could cause diseases and outbreak of fungi and bacteria. The air circulation is also of great importance to prevent this from happening. If the humidity level is so high that the plant cannot evaporate or draw nutrients from the soil, it will eventually rot.
This makes it imperial to have a climate system which can easily be controlled whenever the humidity or temperature level needs to change.
Consistency is key
The regulations for growing cannabis are strict since it's often grown for medical purposes. Cannabis cultivation is subject to GAP and GMP regulations which among other things demand proper handling, storage, and cultivation methods to ensure product quality and safety. This means that cannabis cultivators need to take full control of the climate in the grow room and not compromise on any equipment.
AKIMist® humidification control for cannabis grow rooms
AKIMist is a Japanese technology which can control humidity levels. "AKIMist is known for its low energy use and non-wetting ability," the Ikeuchi team explains. "It produces a "dry fog" consisting of tiny droplets of water below 10µm. The droplets are so small that they bounce back without bursting on any surface. This makes it possible to maintain growth consistency as unwanted droplets will not spread on any leaves or surfaces."
"AKIMist uses 83% less energy than conventional steam humidification systems. One of the most important differences between steam humidification and a dry fog humidification system is that a steam system cannot shut down in between. This means that a lot of energy goes to waste. A dry fog system, on the other hand, can automatically turn on and off whenever the humidity level drops below the limit. This means that a 100% goes into the grow room and nothing is lost."
The AKIMist® technology is built around an atomizing unit which combines water, compressed air and ultrasonic waves. Two separate orifices spray out atomized droplets which collide in the center. Simultaneously they generate ultrasonic waves to further atomize the droplets and homogenize their size into less than 10µm – dry fog.
AKIMist is connected to a sensor system which continuously measures the humidity level in the growing room. "If the humidity level drops below a certain limit, all AKIMist units will start again. The levels can also easily be managed from the control unit whenever a new growing phase sets in and the plants require a different level of humidity," the team concludes.
