There are a bunch of (sometimes hydroponic) indoor greenhouses popping up all around Florida since the near miss in decriminalizing medical marijuana on the last ballot. They mostly just grow crap loads of lettuce and tomatoes (tomatoes and marijuana have extremely similar growing requirements and cycles) which they sell to "organic" places and literally throw away (or in some cases give away) the rest because at this point they're just working out the kinks in their production systems until the real money maker becomes legal.
It really hit me when a friend of mine told me about a greenhouse that was experimenting with RFID to track its lettuce production and I thought that seemed like an awfully expensive way to track a product nobody cared about...
If anyone is curious the way FL has gone about awarding licenses for potential marijuana growers has been a pretty drama filled saga and is a great example of corruption in today's society
