The cheapest solution i can think of is x2 fan heaters x2 timers. 1 timer set for dark with fan heaters variable thermostat set at 20 degrees. The other timer set for light periods with heater set at 30 degrees..? How do you rate the cheap fan heaters as a solution?? would i then have humidity issues? If the fan heaters are suitable they would be working all the time to maintain those temperatures so could i then remove my air circulation fans? This setup as i need two therefore 4 of everything will cost 60 whereas the tube and climate controller hits about 120 each!. If successful i hope shell survive the climate change...
