Watch now: Webinar Root zone management

Hydroponic cultivation on stone wool growing media results in a higher yield per square meter compared to cultivation in soil. In a greenhouse the ultimate climate conditions can be created for plants. This, in combination with Precision Growing, enables growers to give the plant exactly the amount of water and fertiliser it needs. This leads to a strong plant that carries more fruits.

Watch the IPS 2020 webinar

Because organising international meetings and events was not possible due to the Coronavirus, we decided to change the setup of the International Propagation Seminar on 23rd of September. On this day, we organised our first online International Propagation Seminar. This means we facilitated a content webinar of approximately 1.5 hour instead of the original 2-day program. The theme remained unchanged:


The biggest change is of course that we are not able to facilitate the networking part and the practical visits.  Nevertheless, we guarantee an inspiring program with fascinating speakers from different areas (eg. science, plant breeding, crop specialist) who will shine their light on the latest developments in the area of root zone management.
