Aeroponic cannabis cultivation offers benefits, but high-tech method is rare
- Marijuana Business Daily · Sep 18, 2023
Aeroponic cultivation of cannabis involves misting the exposed plant roots with a water and nutrient solution, eliminating the need for a growing medium.
The method results in faster plant growth, increased output, and higher levels of THC and terpenes.
However, aeroponic cultivation requires upfront costs and a learning curve, which has led to its rarity in the cannabis industry.
Maintaining a clean and sterile environment is crucial for successful aeroponic cultivation, but it can result in high-quality, pathogen-free cannabis.
Cannabis is typically grown in a medium, often a soilless medium such as rockwool or coco coir, or in living soil.
Aeroponic cultivation eliminates that growing medium entirely: Exposed, hanging plant roots are misted directly with a solution of water and nutrients.
Combined with careful environmental controls, the method can accelerate crop growth.
“The speed is basically unbeatable,” said Jim Strain, director of cultivation for Cranbrook, British Columbia-based cannabis producer Dycar Pharmaceuticals.
“I’ve done them all side by side, I’ve tried every system, and aeroponics is incredibly vigorous when done right and when the system is healthy.”
Aside from faster growth and increased output, aeroponic marijuana producers cite several other points in the growing method’s favor, particularly:
On the other hand, aeroponic growers must overcome several challenges, including:
No data exists to shed light on how many commercial marijuana growers…
