Very simple actually, you can literally be 100% invisible from IR.

Grow tent like the new Growlab with walls made of IR blocking 99% reflective material.

A high quality LED light like the Procyon 100 (each equal to about 250 watts HID but not very good for flowering) or the Lumigrow ES 330 watt (equal to 500 - 600 watts HID and great for flowering due to the right red & far red light spectrum as well as blue & white emitters)

Small room air conditioner (optional) to keep the room the exact same temp as the rest of the house and keep it sealed, no exhaust to the outside.

LED lights produce minimal light compared to an HID bulb that can raise a room by 10 - 15 degrees F per bulb in the higher wattages in a sealed set-up.

The LED lights each raise the room temp by maybe 3 - 5 degrees in a sealed grow.

All light produces radiant heat no matter what due to the energy contained in it but that easily dissipates and it absorbed in a cool room with a/c.

This is undetectable by FLIR on helicopters and IR guns, 100% certain.
