Case: We Grow

From outsourcing TC to in house production

The Kiri tree is the rising star of the modern industry. The wood of Kiri trees is fast growing, strong, light and resistant. WeGrow is a nursery specialized in Kiri tree propagation and cultivation.n Wegrow is becoming one of the most known Kiri tree producers in the world. Young tissue culture plants are produced and rooted in their main lab in Germany, and then shipped to their nursery locations worldwide.


A few years ago, Wegrow started with buying young tissue culture plants from other labs and localize the rooting and hardening process in Germany. This lead to many uncertainties and challenges. First of all, the tissue culture plants were not always delivered with the same quality. They showed many unequal performances. Secondly, when the production of tissue culture is in house, many aspects cannot be controlled especially aspects such as delivery terms and times. Thirdly, when outsourcing, the company doesn’t have the freedom to control their own clones.

The solution:

Wegrow decided a few years ago to produce their own tissue culture plants and invested in a new lab. The company approached ViVi to help develop a unique tailormade tissue culture protocol for their unique clones. ViVi worked with a team of experienced tissue culture specialists to develop this protocol and trained the Wegrow staff. Further more, ViVi has done an in-depth research on the optimal light source for their clones.

ViVi helped to source all the LED’s in their current growth chamber. The results were very encouraging and Wegrow is up to this day able to carry on the success after the knowledge transfer. The staff from Wegrow is now able to produce, research and fine tune their unique protocol by themselves.

Furthermore, ViVi, as one of the first LED users on a commercial scale, advised Wegrow to continue their production with the help of LED. The ViVi team gathered much research data on the light receipt that Kiri trees require for the growth period. Wegrow has now built a brand new multilayer growth chamber fully equipped with LEDs after the recommendations from the ViVi team.

Added Value:

Wegrow is also one of the many believers in the unique ViVi rooting & hardening tray system. The tissue culture plants are being rooted and hardened in the ViVi trays and reach almost a 100% success rate.

The ViVi trays are used as shipping packaging as well. The packaging regulates the temperature and humidity while plants are being shipped. This guarantees the plants to arrive at their nurseries intact.
