Pretty flowers. 
Your automation has really motivated me. That, and I have a need for more ph meters now.
I'm still doing lots of research on grow automation. There are several people doing some interesting things, but none satisfy my particular list of requirements. My rough plan right now is to use Arduino to sense and control things, but have them tied to a rasberry pi to handle tasks like data recording, webUI, alerts, etc. I started adding up the costs, and it's going to be much cheaper than I anticipated. I've broken the project into 2 parts: sensing and control. I suspect I will end up with a separate Arduino performing each role, but that sort of detail is still unsure. First, I will get the sensing side working the way I like. Then I will move on to automation, or 'control'. Anyway, thanks for the motivation to finally get this going. I'm going to make a ph meter first. The parts will actually cost me about half what another meter would cost. I have 3 reservoirs I want to monitor now, so I don't wanna buy 2 more meters @ $150 each. Once I get the ph sensors working, the EC/ppm and temp should be a piece of cake. I may end up doing temp at the same time to make it more accurate (temp compensation is needed for ph calculations). I think the little interface boards are measuring the temperature, but that's ambient. I want to use the temp of the water.
Anyway, just checking in and rambling a bit.
I'm excited to see your new strains. Hopefully you will find a good pheno!
