The walls of your grow area:

The smartest paint choice is a high reflectivity flat white interior paint that’s designed to repel molds, fungi and mildews, and has little if any off-gassing volatiles in it.

Admittedly, it is tricky to attach Mylar to walls, and especially difficult to fix it to ceilings, because it’s a thin material that can easily rip, wrinkle or scratch. Mylar should be applied with the same amount of care as one would apply a window-tinting film on a car. The material must be absolutely flush to the wall, with no bends or wrinkles.

Thieves use thermal detection drones and handheld devices to gather the same kind of data, which they then use to identify grow ops they can later rob.
