Strawberrys needing nutrients

Going on our 4th year of aquaponics. After running all year, with minimal freezing, it was time to test the levels. Temp was cool in the mid to upper 60′s. Most aquaponic systems once established require very little maintenance.  This is our very first reading of 2013. This shows a 7.4 average reading for PH, 0-.10 for Ammonia, 0 Nitrite, and high Nitrate of close to 80ppm. Why are the other two not showing, but yet plenty of Nitrates?  Simple, the readings on the scale [...]

2 month temp reading.

During cold and freezing the beneficial bacteria will die back, and not convert that much ammonia.  That’s okay, the fish stop eating below 50 or so degrees.  I couldn’t get them to eat until 55-60.  So having the system die back a little was okay. From Jan 13 2013 to April 14 2013 you can see an increase in fish tank tempature, as well as inside greenhouse temp.  After 4/14 I had some issues, and didn’t grab data.  The SD card on [...]

Greenhouse Dashboard

As stated in a prior post a new controller has been developed, this one based on Raspberry PI. I have been asked, why not bridge the two (Arduino and raspberry pi).  The simple answer, is eventually. With raspberry PI, there is a Linux operating system.  On Arduino, I have to code everything.  Each have their own benefits and disadvantages.  I’ll have to figure out how to talk to Raspberry pi over the network and then serial to the Arduino.  Right now, the GPIO ports are working [...]

It’s been a few months since our last post. It’s now middle of winter, and my prior arduino controller stopped working. So I decided to switch to Raspberry PI, where my IT background would be much better suited for. Here is screen shot of our main TV with the dashboard displaying
