I received a cool email from RWC reader, Christy – who wanted to share with me her winter worm bin set-up (after she saw the recent post about building a small winter bin). I asked Christy if I could share her info/photos and she was more than happy to oblige.
Here is what she wrote:
I saw your latest post about a worm heater and I thought I would give you pictures of the heater I set up in my parents worm bin. Their bin is sitting in their unheated Rabbit Barn. The barn has dropped below freezing several times (once for almost a week) but the bin has stayed above 65 degrees on the heated end.
The Heater is really simple to set up. I used a one gallon glass jar and a 2 – 5 gallon aquirium heater. The total cost is less than $10.00. I filled the jar with water and cut a hole in the lid for the cord. I place the heater in the jar according to the directions. I use an aquirium thermometer to check the temp. of the jar. It stays between 72 – 76 degrees. The jar is barried directly in the bin and placed close to one end to allow the worms a place to go if the heater gets too warm. The worms have stayed very active all winter even during very cold spells. The bin does dry out a little around the heater but it is easy to mist the area every few days.
Thanks again, Christy – this sounds like a nifty system!
