Substrate analysis - best choice for coir

摘要

Switching from one substrate to another is a choice for growers. The price of a substrate is commonly the number one reason to investigate alternative options. Per Weerheijm, managing director Dutch Plantin, says, "On some horticultural nurseries, e.g. in Korea and Mexico we are also seeing that the choice for coir substrates has been based on the extra cost savings realized with coir compared to rockwool when disposing of the material after production is finished." Replacing rockwool with coir, however, means more than the elimination of hazardous disposal problems.
