Twenty cannabis growers from all over Europe and the world recently gathered in Austria for another industry event: a one-day invitation-only masterclass on cannabis propagation, hosted by Fluence, one of Europe’s largest cannabis clone producers, at the Flowery Field in Vienna.
The day included lectures, live demonstrations and a rare guided tour through a facility that is usually closed to outsiders. “It was a good mix of practice and theory,” says Fluence’s Theo Tekstra. “In the morning we had a theoretical block, then we had an in-depth tour of the tissue culture laboratory and the mother plant and reproduction areas, and in the afternoon a practical workshop. Everyone saw and participated in the whole process.”

Historical installation
Flowery Field was founded by Alexander Klima, a former law student who noticed that Austrian regulations discriminated between plants and their uses. In practice, this means that cannabis can be sold as an ornamental plant, as long as it is not harvested for consumption.
What started as a small shop selling houseplants along with cannabis cuttings, has since become a major production site, with a hundreds of square meters of mother plant and tissue culture laboratory where eight technicians work every day. The company now focuses entirely on cannabis clones, supplying customers in Austria and neighboring countries, often with same-day delivery to selected locations.
Standardized expansion
For Franz Joseph Sima, Fluence’s long-time propagation specialist, the masterclass aimed to show how standard procedures transform the mother and clone phases of cannabis production. “Many producers still have challenges in the expansion phase,” he said. “At Flory Field, these processes have been refined over twenty years. We wanted participants to see how a consistent and commercially viable system works in practice.”
The workshop covered everything from mother plant maintenance and replacement schedules, to light intensity, watering and pest management. The attendees received the full procedure afterwards. “The only condition,” says Franz, “was to be there.”

From tissue culture to mother plant
Participants followed the entire production chain, from tissue culture and virus testing in the laboratory, to cutting and preparation of clones. Flowery uses PCR testing to ensure cultivar stability and purity, a practice more common in pharmaceutical or ornamental horticulture than cannabis.
“The contrast was striking,” says Theo. “You have this sterile white lab on one side, and on the other a fully commercial clone factory based on the mother plants. Seeing both under one roof gave people a real sense of scale.”
Opening the doors
One of the main takeaways from the day was the atmosphere of openness. “In the Dutch horticulture industry, growers thrived by visiting each other and sharing knowledge,” says Theo. “In cannabis, everyone tends to close their doors. Events like this are a step to change that.”
The small group format helped. What began as quiet observation soon turned into a back-and-forth of ideas, with growers comparing notes, solving problems, and sharing their methods.

Interest in the event exceeded expectations, Franz and Theo both say, and Fluence is already considering repeating the format. “We can do another show in the same place, and maybe even one in the US. It’s something that people can clearly see. In cannabis, very few cloning procedures have been proven for a decade or more, so showing something that has stood the test of time makes a big difference.”
For one day, Flowery Field opened its doors, its laboratories and its mother rooms to a small but focused group of professionals. “In a sector where practical knowledge tends to be kept close to the box, that alone was worth a visit,” concludes Theo.
