Grow Tent Reflective Film FAQ's
Mylar is a thin metallised sheet at around 97% reflectance, and it works best taped flat on a smooth wall. Panda and blackout films are thicker polyethylene at around 90% reflectivity. They take staples, sit well on rough or uneven surfaces, and wipe clean between crops. Choose mylar when you want the most light back; choose poly film when the lining has to take a beating.
Usually no. A tent arrives with reflective lining already in place. Buy film when you are lining a room, cupboard, shed or a frame you have built yourself, where there is no lining at all. It is also the patch for a tent interior that has worn, scratched or torn after a few seasons.
The black backing blocks light from passing through the sheet. Your grow light stays inside the space, which matters for the plants' light cycle and so the room does not glow from outside. It also stops outside light leaking in, which is what lets a properly lined room hold a strict dark period.
