01. A cultivator in Oldambt

Holigram — a Dutch cannabis cultivator within the Closed Coffeeshop Chain Experiment.

One of ten selected Dutch cultivators within the government framework. Indoor, regulated, fully traceable — from seed to coffeeshop.

— 01 The story

A Dutch cultivator
within the experiment.

For years we fought for it, and finally our team gets to do what they do best: cultivating legal cannabis for recreational use. Holigram has been designated to participate in the Closed Coffeeshop Chain Experiment.

We are one of the ten cultivators that may supply coffeeshops in the eleven Dutch municipalities participating in the government cannabis experiment. Our batches are analysed in the lab according to prescribed methods — the packaging shows exactly how much active substance each unit contains.

We are not a retailer, not a trader and not a marketer. Our role is clearly defined: cultivating in small controlled rooms with LED lighting and hightech climate control, testing via accredited labs, packaging in compostable PLA — and supplying the participating coffeeshops.

Founding & fusion The activists and the entrepreneur.

We are John and Ines Meijers of Stichting JoinUs and Jetze de Raad of BioBizz®. We joined forces and combined our knowledge, experience and passion. We are Holigram.

We are unique within the experiment: as 'model cultivators from Bierum', John and Ines have gained national recognition as advocates for better cannabis policy. Jetze has been an entrepreneur, scientist and founder of BioBizz® since the 1990s — the most-used organic plant nutrition for cannabis worldwide. The Holigram team brings together the best of both worlds.

Regulation, transparency and careful cultivation must replace the old tolerance policy — and it starts here, in eleven municipalities.
