Light Blocking Material

by Screwstick about June 12 - report

Has anyone found a light blocking material that allows air to pass through? The vents in my grow room will be covered but I would like a little extra protection.

    In my new room I installed 2 dryer vents with the side that usually is outside on the inside. They have dampers that allow air in but help to shield light and the cover points down toward my floor. I also installed 24" of flex duct to the vents outside of my room. Absolutely no light gets in.

      I saw your setup and it looks great. What I have is a rectangular duct that’s a dog leg and I plan to mount 6 x 10 inch fans inside the room to help pull air in and off the floor. With the covers on the outside the dogleg ducting and the fans on the insid...  more

      It’s in the basement and there is no light on down there during the day anyway. Honestly I am more concerned with light getting out during the daylight hours if I need someone to service the furnace or well pump

      That's what I was most concerned with also, if a meter reader or someone working outside seeing the lights.

      Yep, I am in a legal state but growing is still on a need to know bases and no one needs to know. I think thief’s are a bigger concern where I live

    A 90 degree HVAC elbow of any kind or size will work. Light can’t turn corners unless it is reflected.

      I will save my nylons for centering punches to dies in die sets and Saturday nights.

      I don’t bring fresh air into my grow room except for when my lights goes off and all the Co2 gets sucked out.

    I use air conditioning, so i can use the light blocking material you can find at Walmart or most stores. Peace

      I dont follow that, do you mean you dont pull in air from outside your room? Do you use C02?
