Just came across this interesting talk on the different growth rates with the same amounts of light spread out over different time periods.

With all the different I2C light sensors out there, LED level controllers like the one he describes at the end of the video would be relatively easy to build with an Arduino. Especially if you could live without the blue-tooth functionality (it: to change the set level for a different crop, you would need reload the logger from your laptop)
I'd be happy to put a note about the Pearls in the tools section here. But thought I would check the forum first to see if anyone was actually interested before I did something like that.
I will look around http://forum.goatech.org and see what the discussions are like. I'll sign on if there's something I can make a positive contribution towards. Keep in mind that our work is pretty tightly focused on hydrology, rather than Ag.
