    Grow Tent Venting? Blocking light but still allow air ?

    Hi Guys,

    Ive got a Spider Farmer® 5’x5’x6.5′ 150cm x 150cm x 200cm Indoor Grow Tent and I want to
    open one of the vents but still block the light.

    What are you guys using to block the light/pests but still allow airflow?

    Is there a circular foam insert or something I can put in the hole? Love to know what you guys
    are doing on the fresh air side of your grow tents but still block light from escaping.

    Fatty...

    P.S I already have the spider farmer Inline Intelligent vent, ducting, carbon filter etc mounted inside
    the grow tent and venting to the outside. I just need a way to deal with the fresh air side of things.

    I just add a few feet of flex ducting and ensure it's kinked to prevent a direct line in. oh yeah - metallic still reflects the light in, but darker colour works great.
    A happy Canuk. Growing has turned intoa an enjoyable hobby. one 3 by 3 by 5 tent with Mars Hydro TS3000 and one 2 by 4 by 6 with 2 spider farmer sf1000's and a Best VA reflector 600. Home-made living based loosely on recipes on-line.

      I've been having good success using this cut to size... and can stick over the vent opening.
      Filters the air and cuts down some of the ambient light from directly going in...
      Search on google or amazon..

      It is nice extra filter layer on any intake vents

        I had a 6" elbow I painted flat black on the inside. The stuck it in from the inside of the tent pointing down. Then laid some black painted cardboard under it. Almost no light found it's way out.

          you can buy a "light baffle for grow tents", they are the exact size i believe (never used one) Google it i am sure you will find..

          Or you can build a light baffle box, something like this

            My intake is near the floor against the outside wall. I would use a big blanket stuffed between the wall and upper half of the tent to block light from going up. I now only have a 6" collar with a screen on it and opened up the tent vent panel so without the blanket I was getting tons of light out and in the bedroom too.

            But I turned on the central air and the register the vent is about 4 foot away behind a chest of drawers so all the cold air was getting sucked up into the tent. Drove the temp control crazy! Had to go round up another blanket.
