Adafruit forums user sketchy posted this great project from his blog – check out more info on the full build here.

I’ve put the Ladybug Shield together with other hardware and software to implement a kitchen farmer plant food adjuster. For now I am calling this the “Ladybug Plant Food Adjuster.” I am currently testing/using it in my home.

The home farmer will be growing lettuce, herbs, tomatoes… within their home, likely the kitchen. This is in contrast to the more expert hobby or professional that has “industrial capable” pH, EC – and other probes, honking LEDs,…i.e.: knows A LOT about growing vegetables and herbs and needs super fine control of plant food adjustment…

…What The Ladybug Plant Food Adjuster Does

The Ladybug Plant Food Adjuster automatically adjusts the nutrient and pH level of a reservoir of water (the hydro part) feeding growing plants. It is for people like me that enjoy fresh vegetables and herbs. We have many reasons to supplement what we buy with what we grow in our kitchen. While I garden both indoors and out, I live in an environment that does not support growing vegetables and herbs year round. Besides, in the winter it is rainy and cold. During the winter I don’t want to spend time in an outdoor garden but love being surrounded by healthy growing plants in my kitchen.
