Hi, Recently plant sensors have started to appear. This is a one sensor per plant which records temperature, light, moisture and nutrient levels. Potentially these can put an end to all the anecdotal evidence which dogs bulb growing. When I say "warm and wet" it means something completely different to someone who lives in a different climate. Anyway I want you to know that we will be happy to host records from plant sensors on the PBS wiki. -- David Pilling http://www.davidpilling.com/
