Facilities built by 4trees cannabis

Building a micro cultivation in Canada requires a lot of planning and expertise to ensure its success. You can design a state-of-the-art facility but if it does not get approved by Health Canada, all of your hard work was for nothing. From fully automated feeding/draining, lighting, fertilization and environmental control to sealed growing environments, our facilities offer several high end features to ensure your success.



Grow tents, rooms, and greenhouses. Grow your 4 plants in style.


2,152+ feet squared of canopy space plus building

Proudly shaping the indoor growing cannabis industry in Canada and beyond

We are proud to stand behind all of our work and always make ourselves available to our customers. The team at 4trees takes pride in our work and the better our customers grow, the more we grow as a business. 

Although its a shame the legacy market is fading, the best time to dream of owning a successful cannabis business is actually right now.   

While we wish we could be on site building, we no longer offer physical build-outs due to the worldwide demand we have for remote planning services.

We look forward to possibly turning your dream in to a reality!
