Mar 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.

Safety and efficacy during cultivation


In the upcoming Medical Cannabis workshop in New Zealand, Matt Hayes will discuss GACP and GMP.  Below is a brief description of both GACP and GMP.  In a recent article on MMJ Daily an Australian manufacture has gained valuable GACP certification in order to enable companies to comply with European regulations.


WHY GACP & GMP? To ensure quality assurance, safety and efficacy during cultivation of plant materials used as sources of medicinal products (Active Pharmaceutical Ingredients, API).

To ensure manufacturing quality assurance, safety and efficacy, GMP quality must be built into each batch of product during all stages of the manufacturing process.

GACP-GMP guidelines provide a framework for compliance. You must validate your production processes.


Good Agricultural Collection Practices (GACP)

  1. Propagation>>>post-harvest.
  2. Produce a botanically-derived API.
  3. Validated & documented cultivation, germplasm & inputs, facility & climatic conditions, harvested product testing.

Good Manufacturing Practice (GMP)

  1. Post-harvest>>>packaging & labelling.
  2. Purification, processing and packaging of raw API into finished medicines
  3. Validated & documented processes, production inputs, facility & equipment, & finished product testing.


A product-focused approach helps to define processes, facilities, equipment and workflows:    Product>Process> Licence>Site>Facility>Staff.

Each product has a defined specification, which defines production.
