Hey,
I've never used a fan heater, so I don't know how much help I can be there. My thoughts being that they're not particularly quiet, so if that's going to be an issue, perhaps you could use Oil fin heaters and use a fan to blow through it.
If you do decide to use to fan heaters, I'd keep your normal fan.

Perhaps try ebay for a Temperature Controller? (as $120 seems abit steep)


Best of luck,

Phant0m Reviewed by Phant0m on . Temperature control solution? White widow is now 7 days into flower stressed with yellow tops which pushit has helped me with :thumbsup: 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 Rating: 5
