Jan 2020




Unfortunately due to current global circumstances and the new self-isolating restrictions for international travellers to prevent the spread of Covid-19, we have no option but to postpone the Grower2Grower Medical Cannabis workshop on the 31st of March.    

Hopefully we will be able to reschedule later in the year subject to the control of the global pandemic.

I will make sure that those who registered for the postponed workshop, have first option to re-register, if and when we are able to proceed with the workshop in the near future.

Introduction on Key Note Speaker Sonny Moerenhout:

Sonny Moerenhout was responsible for the international cannabis business within Grodan. In this position he consulted growers on cannabis cultivation in countries where medicinal cannabis is legalized. His cultivation experience and expertise are strengthened as result of his involvement in trials at Wageningen University. Sonny holds a master’s degree in plant science from Wageningen University with greenhouse horticulture as his specialization.

Sonny was ‘born’ in a greenhouse, his parents were eggplant growers for over 25 years. Whilst at Grodan he was advising growers around the world (Europe, Asia & Pacific). In his last 3 years with them he was fully dedicated to Medicinal Cannabis with a focus on cultivation solutions for cannabis growers. He understands the importance of working with the pharmaceutical, horticultural & hobby industry in the cannabis sector. Through his experience and his extensive network he’s learnt that cultivation expertise is a crucial factor to make growing facilities a success. As a result, he decided to establish with other professionals, the consulting firm Cannabis Cultivators.
