DIY Grow Tent Dual Window Vent
One of the questions that I continue to get asked on Instagram is where can you buy a dual 4 or 6 inch window vent to vent the intake and outtake fans for the grow room or grow tent. I have searched online and found dual window vents to be a hard items to find. they were usually sold out everywhere or were overpriced at $150 or above. This is where I got the idea to create a DIY window vent for under $50 that not only looks professional but works just as good if not better then the window vents you would order online and everything can be purchased at your local hardware store.

I am located in Canada so I purchased all my supplies from our local Home Depot store for under $50 but these items can be found at most hardware stores across the world. You should all ready have your intake and outtake fans and your 4 or 6 inch ducting.

For ducting the best place for the price would be from your local hardware store as your local grow store will charge more.

Window Vent Instructions Step 1 & 2
Measure the width of plastic casing on the dryer vent and write it down. I was using 4 inch vents for this blog so in my case the width of the plastic casing was 6 inches.
Measure the height of your window from the lowest point in your window frame to your highest point .
Window Vent Instructions Step 3 & 4
Cut the plastic to the height of your window frame from its highest and lowest point you want it to fit nice and tight.
Add 4 inches to the width of your dryer vent casing and cut the plastic to that width. For example the width of my casing was 6 inches so the width when you add 4 would be 10 inches this leaves 2 inches on either side of the plastic for strength when in the window.
Window Vent Instructions Step 5 & 6
Pop the cover of your dryer vent off the and disconnect the ducting.
Use the dryer vent casing as a template and mark your holes on the plastic and cut out your holes.
Window Vent Instructions Step 7 & 8
put your dryer casing back together and slide it through the holes you just made in the plastic window cover.
There will be some small holes left in the ducting you will need to tape these up for the most efficient air flow.
