Passive air flaps letting light in.....

My apollo tent only has mesh/velcro passive intake flaps at the bottom of the tent. NO ducting holes. (grrrrr) It does have 3 ducting holes up the top of the tent ~useless for passive air intake, as the air must flow into the tent from the bottom, correct? cool air in from bottom, hot air out the top.

THIS GUY sums up the problem pretty good.

So..during flower how do I get air through these vents without letting light in?

thanks!

Good question I have the same issue with my tent. So far I just try not to let much light enter the room and use a green light while working during night period

I don't know the answer but I do know if you which to autoflowers you know longer have the issue related to light

There are black carbon furnace filters available or you can make a light trap vent out of cardboard or thin wood.

Or cut a hole at the bottom and attach a panda film "sock" (to make it light proof) to put your ducting in.

Cardboard around the area that you tubing will go. Seal it with tape and dark cloth. Give the tubing a turn or two and attach a filter at the end so bugs dont use it as a highway,

u can not give a shit about it cause it won't bother anything.

Great info thanks
