After recently going to the hydroponics store and seeing a $3000.00 box that automates the garden, I want to of course make my own said box for my tomatoes, peppers, and herbs
I do realize this is a first post so I will give some info on myself. I am not a complete noob. I earned most of a computer engineering degree from FSU before I fell into the world of horticulture which I really am just in love with now and will be moving to UGA next semester.
I am working on using a BeagleBoard using the tut in the blog on interfacing arduino to it. The BB will provide a web interface while logging data allowing me to gather cool data about my plants

I have so far gotten temperature, light, ph, and humidity running through a console. My first step is to just get it reading everything.
The PPM / TDS solutions out there have just killed me. Vernier offers an analog conductivity (tds) meter.

Thanks in advance. I am stumped. Any electrical gurus out there post up! I did search the forums first as well.
Thank You!
