  • lights-on cycle, between 70 and 80 degrees Fahrenheit
  • lights-off cycle, between 64 and 71 degrees Fahrenheit

So you better be ready for those heavy temperature drops!

Moreover, they can cause damages and even burn whatever is placed directly next to the heating unit itself, or too close to it.

Most growers on a budget usually use oil filled heaters while professionals go for heaters fitted directly in the inlet ducting.
