Easy Light Trap for Grow Tent Intakes

My grow tent is in my bedroom and the light coming from my intake was so god damn bright. I had to fix it somehow. So i will show you what i came up with.

Materials i used:
- Piece of cardboard (about an inch wider then the perimeter of the intake vent
- Aluminum tape
- Duct tape
- velcro used for fabric (cheap on amazon)

- 4 inch ducting
- black spray paint
- scissors (fuck it, you can use a steak knife if you want)

First, i measured the length and height of the border of fabric lining the intake vent. I then cut the velcro strips accordingly and stuck them right around it:


Then, i covered the piece of cardboard in aluminum tape. Took a piece of 4 inch ducting and traced 3 holes before cutting them out. Then i placed the other half of the velcro strips along the edges:


Then i took 3 lengths of that 4 inch ducting and secured them to the cardboard piece using duct tape:


I spray painted the inside of the ducting black to prevent light from
Reflecting out. Bent the ducting at roughly 90 degrees and kept the angle by duct taping inside each piece of duct. Then i just stuck that bitch to the tent and voila:


**NOTE: if your duct angles aren't sharp enough and you are still getting a lot of light coming out, lay something black right underneath the duct ends on the tent floor. It will prevent light from bouncing off the floor up into the duct. Even a dirty ass old black sock would work.

 

Where do you pick up those?

 

Sweet. Maybe i'll test it out. I have lots of velcro left and nothin to use it for.

 

For sure you could mount that outside the tent. As for the carbon pad, i have no idea. I was wondering the same thing.
