I should get a few pics to upload but my site is a ~8x10 garden shed. I moved to the property this summer and I have had two nearly 100% loss winters. So I decided to keep my bees in the shed this winter. It required some repairs and I insulatedthe shed. I then got electric setup with outlets and lights. I used dryer vents for ventilation on opposite sides of the shed. One has a fan that sucks air in and the other passively lets it out. That is set on a timer to run for half an hour twice a day. I also have a small electric heater in the shed. Right now it's set to a timer and I have approximated the 40 degree setting on it. I do have a thermocube in the mail. It's a neat little device that you plug right in to an outlet. It has a thermostat in it that will only power whatever you plug into it between 35-45 degrees. So when that comes I will simply use that instead of a timer. I have a wireless thermostat in there and the monitor indicates that the temp is between 30-50 right now, but that should be more tightly regulated once the thermocube arrives. My doors are essentially sealed but when it got warm today there were a few bees outside so I wonder if there is a small opening at the base of the door. I just opened the door and let them do their thing.
So anything I should be doing differently?
Should I continue to open the doors on nice days?
Should my fan run more often?
Should I stress out about finding that small crack? It's dang dark in there when I look from inside.
It seems a lot of my loss comes in March when we get a week of subzero temps. Hoping this avoids that problem and I can be more successful in the future. Replacing bees is expensive.
