Started building my sulcatas long term outdoor enclosure. I have a 10x12 insulated shed with power running to it. Was planning on using an oil filled electric space heater. Are they safe to use? Cons/pros? Also since they will be outdoors now I won't be able to monitor their temps as frequently. Any recommendations on thermostats that I can access thru my smart phone to allow me to monitor if the temps spike/drop?
