The fact that these lush, green crops were grown in drought conditions to be shipped to other parts of the country stuck with Ashton and later became the inspiration for his robotic farming startup Canopii , which looks to shrink produce supply chains. Portland, Oregon-based Canopii builds robotic greenhouses that can autonomously run the whole crop-growing process from seeding to harvest without human intervention. These greenhouses can produce up to 40,000 pounds of produce a year while requiring only one spigot of water and taking up the same space as a basketball court.…
