T issues in LED grow tent

Hi, i'm Going to migrate from 1200W HPS to 1200W LED in a 4X8 grow tent.

The room at night it's around 17°C and it's a very low temperature for root system , at day T is around 20°C in the room where the air inlet is.

I would like to rise couple of degrees My grow Room. But i dont waste a lot of electricity heating the room with a 2000W heater. Maybe some heater only for root system?

Any advice?

What 1200w led...they don't really exist

Heat mats..usually for seedlings but what the hell...

Use a dehumidifier.

When the temperature from the roots it's lower from 18° the veg it's very slow. I grow in coco and y like a explosive and fast veg.

Thats a cheap option not bad at all.

I use a dehumidifier in my outer room to keep it both dry and warm in winter months. Two birds and all....you know

1200 watts of boards is not needed to replace 1200 watts of hps. 60% or so should do it and that 400 watts less heat solves the T problem.
