Floor heat foil inside grow tent...cold problem

[pollen205]

Thinking about floor heat foil from 100w to 200w
Also a option is heat pads 45w for terrarium
Also infrared ceramic bulb for heat 100w..

What will help the most in 80 80 160 cm grow box...
Think about vent off during this cold time.

It is very cold at night

You could have it outside the grow box blowing at the intake vent.
It has a slight glow from the element, I don't know if it would cause problems.

Put more lights in to keep it warm but a heater is nice for when the lights are out.

A small baseboard heater with a separate thermostat is what I use to keep my chilly grow room warm when the lights go out. Had to wire up the thermostat with cords to plug everything in but it works like a hot-damn and has for 17 years.

would a seedling heat mat work for that area? They make the square ones that are like 20.5 inches by 20.5 inches and use like 45 watts.

I use cheap white foam, just put it under the floor liner. For heat I use a electric oil heater but I also have a lung room.
