how do you measure the soil moisture? I didnt see anything in supplies and both graphs didnt had anything.

  Others have linked the gadget he's using. But I'm wondering if a scale would work at least as well. They might be cheaper/more precise/not subject to local variations in the soil.

    And when the plant grows?

      > And when the plant grows? Great question. I build something similar without a moisture sensor, the key to obtaining proper data is to know (and control) the exact amount of water you elect to distribute. The self-learning (ghetto A.I) software that I wrote would try to predict the next (optimal) watering event. You can start to tell how much weight the water adds and how fast the plant consumes it after a couple of iterations. Plus the soil will usually outweigh a plant by a considerable margin.

        Ghetto A.I. haha TM Some interesting things to look into maybe? Temp, humidity, pressure, maybe put the plant in a transparent pot and flash a light through it (what?) I don't know I've connected a solar cell to the web and have been gathering data cool to see/check while at work.

          The environment was pretty controlled, and I haven't touched anything of that nature for a couple of years now. But, the solar cell thing sounds interesting. Cheap or? Got any links you can share with me? Thanks!
