I am planning on building an incubator in the future and was discussing the heat source, thermostats and timers with my husband. He asked me "why don't you just use one of those really small ceramic heaters for the heat source?...they already have a thermostat mechanism" This may be a stupid question...but could I use one? They have some that are about 4" tall at walmart for $12.94. I know I may have to play with it a lot to get temp right and may have to use a timer...but Could I use this? Any advice or opinions?
