Q and A: Stale whole wheat flour, Hopi Pale Grey seeds, and storing dehydrated vegetables — 1 Comment

  1. If anyone is interested the heat mats are made from a plywood plank 44 1/2 x 12, 4-furring strips 40″ long, and an 18′ string of rope light. Position furring strips in about 1 1/2″ on plywood then space evenly. Weave rope lights around strips and attach with cable clamps and your all set. Very easy. Works great.
