I got a scio dev kit from kickstarter. I backed it because they claimed at launch you would be able scan the leaf of a living plant and determine if it was sufficiently watered. Unfortunately this functionality, along with many other promised applets, was never built and the dev forums are prettmuch dead. When I looked into building my own model, I found the time required is pretty huge. To build a remotely useful model, one would need to scan between 200 and 300 samples. That means 200-300 individually potted plants for every plant variety you want to measure!!!
