I am step by step converting a spare room into a grow room. I have a four inch vent going out through the roof, osculating fan. proper lighting, and a 6/18 light schedule. My question is this: should I use Mylar on the walls, or would it be better to cover the walls with mirrors? ---

Mylar! Mirrors absorb the light. ---

I already looked it up… just curious about mirrors. Thank goodness they suck, Mylar is much easier to set up I think. I am considering adhering the Mylar to panels and slightly leaning them at an angle over the lights and toward the plants. Any thoughts? ---

Mirror can actually create “hot spots” on your plants. Def Mylar @badmaster1 ---

You could use thick cardboard for panels and tape it to the backside. Easy peezy and light to move around. ---

Mylar is better at reflecting light. Panda film works, too. Or white paint. ---

Not sure of your set up…I don’t have an expensive tent…I have a room that is 3x5 that is the water heater room and I put mylar on 3 walls then 4th side is cardboard with mylar… Total cost was less than $20 add light ![Mw8](https://global.discourse-cdn.com/growingmarijuana/original/3X/a/e/aee9f4e7ce307a4293beafdfdcc95022ac89e1ee.jpeg) You can see it in pic …good luck ---

3/4" pvc pipe, some 90’s and two tees will make a frame to hang mylar or a white shower curtain. adjustable and highly mobile.
