RHP has published a factsheet on weeds in the culture on substrate. This factsheet is part of a series on specific topics related to potting soil and growing media.
The factsheet on weeds in the culture can be found in the knowledge base of RHP. The factsheet is intended to inform certified companies and their customers on weeds in the culture on substrate, how weeds can enter a crop unnoticed via various infection sources and how to prevent problems.
About once a quarter, a new factsheet will be added to the knowledge base. Topics that are planned next are, for example: heavy metals, unfertilized potting soil, (liver) moss, microplastics and PFAS.
