GrowStack Ltd came together in 2016 when we realised that the vertical farming market was about to explode and here we were with the experience of building a largescale bespoke vertical farm deep under-ground in London. We have the combined knowledge and expertise to build a vertical farm virtually anywhere and the passion and drive to make sure that what we build works and becomes a successful venture for our clients.

He has a broad experience of growing in some of the harshest environments, proven management skills, a consistent record of success and exceptional crop knowledge.
