Would a heater going on every hour and a half for half of one hour be a bad idea? It would be done to reduce power use but still generate a small amount of heat. Temperature might fluctuate 10 degrees or so from 65-70 to 75-80. Would this oddity in temperature fluctuation be stressful?
get a heater with a built in thermostat, that way you can let it do the leg work. my heater is set to 68 kicks off after the lights have been on for about 30 mins and stays off til about 1 hour after lights go off at night. that way my temp only flux is during their night time when temps would normally drop. the power draw when the heater is waiting to turn on is insignificant. I don't think that the temp flux in your scenario would hurt to much but the more controlled you can make it the better.
