Hi all, I'm concerned about light getting into my grow room from the intake hole. What is the best thing to use to make sure no light is getting in? that will cover the intake without constricting air flow.

I had thought about buying some curtains to hang above my window to make the room pitch black but I thought I'd ask first and see if there is a more cost effective alterative.

or you could cover the intake with 2 layers of kitchen cooker hood material, no building involved just cover the intake hole and tape or staple it in place, plusits carbon so it helps with nasty niffs too :D

:D Couple layers of that stuff works a treat. Air flow isn't really restricted at all and no light gets through it. ;)

Do 90 degree bends in the ducting and an inline fan help to stop light coming through an intake?

I just popped some green scouring pads (16 altogether, 4 layers deep, taped at the joins) onto the inside face of my passive intake this morning. seems to be lightproof and still maintains the airflow as far as i can tell. not 100% sure about them though as it's only an experiment, so the diy buffer might be your best option. Could do both even :headpain:

Seems bloody hard work doing all that. I just put some cooker hood filter over my passive intakes.
Also have a 120mm intake fan with filter covering it, for the summer temps.
All works perfectly.

E2A: If using passive intakes, make them 5-7 times bigger than the extraction

Do you have a set of bubble bags ?

If so these are ideal as they usually have a small 70micron bag which no bug will get through, just pop it over the end of your intake pipe and pull the draw cord tight, easy to kepp clean as well.

e2a: sorry thought you were trying to screen your intake not light block it. :wink:
