Vertical farms have been theorized about for years in media and by entrepreneurs but until now, nothing big has gotten off the drawing board. Will Allen’s legendary Growing Power looks like it will be the first to test the concept in reality with a proposed 5 story expansion to his Milwaukee headquarters that was put up for approval by the city planing commission last week.
The 35,000 square foot building would be oriented toward the south with a greenhouse like structure capturing light and heat, even in the dead of winter. The building would circulate air and water to provide nutrients for a variety of plants as well as tanks of fish – an aquaponics system that Growing Power has been working on at a smaller scale for years. Additionally, classrooms, a demonstration kitchen and various meeting spaces would be provided. Produce from the structure would be sold on site.

Growing Power is a non profit and as such the new expansion has been made possible by a fund raising effort from various Sources. However, part of the group’s mission is to explore commercial applications for the systems and technologies developed, some of which have already borne fruit, so to speak.
We recently reported on SweetWater organics, a commercial aquaculture operation in a former factory on Milwaukee’s south side which is using Growing Power’s systemic methods to grow both lettuce and perch for local restaurants and consumers. That operation has yet to be proven financially viable but is less than a year old.
Additionally, many companies, such as Bonterra Vinyards have found ways to partner with Growing Power either for their own charitable purposes or as ways to boost their own employee morale and community involvement.
As TreeHugger’s Lloyd Alter points out, developments like these may not feed the world all by themselves, but the technology is fascinating, inspired and obviously making waves.
