Ok i did it this weekend. I got an outdoor extension cord, took off the female end, and made it into an outlet box which I mounted my two-outlet timer to. One goes to the cookie tin heater for the water, the other goes to another cookie tin heater I glued a picture frame to so light is emitted as well.
me new outlet, screwed to a removable board which rests on nails. In the spring, I'll remove the board entirely.
cookie tin with window for light.
cookie tin for water tank
All of it from afar, with my coop winterized with 6 mil plastic. The green cord runs to the outdoor plug on the house.
Both tins use 40W incandescent bulbs from the dollar store.
Both tins were from goodwill at 1.99/pc
Ext cord was $13.00 from Lowes (landscaping cord, 12 gauge)
outlet box and faceplate from lowes all for under $5
Two 6 ' cords for two heaters were 1.19 each from Lowes.
I had the light sockets on hand (but they are .99c from
walmart).
Total cost: 26 bucks.
