For the homebrew beer industry there are SaaS based apps to help you keep track of your homebrew beer. BrewersFriend.com and BeerSmith is a good example. Each brewing session you track through the process, input data into the process, then at the end taste/evaluate so you have detailed easy to read notes/graphs on each beer recipe you brew. Plus it has built in tutorials, calculators, etc. You can even clone a recipe session and keep doing it over and over, each time taking more detailed notes to refine your recipe. I know there a couple right now for cannabis but none really are doing the SaaS style as the main focus. I know it's because growers didn't want their grows tracked but now as more and more States become legal and for those where it's legal to grow at home legally, are you still using notebooks or are you using some online solution to track grows?
