"I was debating between an arduino with an android app to keep track of crops or trying an all in one with a raspberry pi. The price of a pi want much more than the arduino uno so I went with the pi, waiting for delivery.
Can't wait to get it…"
"Does anyone know how hot it gets inside the PVC pipe? I would be concerned about the PVC breaking down and leaching chemicals into the water. PVC only needs to reach around 140 degrees to cause deodorization. "

Using my system as an example, I have 3-300 watt heaters to protect…"
I have my system now covered in a large hoop house. The temperature starts rising as soon as the sun hits it. Yesterday it got to 52 in there. But it started at 32. The water temp just doesn't seem to catch up, will this happen or is it not?

I am really pleased…"
Hello all,I represent Sand Creek Farm and Dairy in Cameron, Texas and would like to introduce myself.
