be careful if you are using a proportional thermostat. I just got a herpstat 4 and they sent a warning for thermostats. one, they use a component called a triac. this is what regulates the power. and they give warnings with some generators, most don't output clean enough power and the thermostat will not work properly. computer uninterruptible supplies, are not recommended as they typically produce modified sine wave that will not allow the thermostat to work properly. this information came from documentation that came with my proportional herpstat 4 from spyder robotics.
Could only afford the hydrafarm so I think I'm all set
