There are many advantages to using stone wool for many different crops. Cultiwool has engineered their products (plugs, blocks – cubes, and slabs) in such a way to fit the cultivation requirement of cannabis. It is important, especially because of the unique aspects of cannabis production; uniformity and hygiene. Whether it is because of genetic instability or varying conditions of growth, uniformity is a key to success and increasing yields for all growing stages, from propagation, to vegetative stage, flowering and harvest. Maintaining a hygienic environment in the cultivation facility is crucial to avoid crop and yield loss. The requirements are high for the quality control and certifications of cannabis production facilities, such as GACP in cultivation and GMP in post harvest.
