How do you light proof a Grow Tent for fans?

[StonedPony]

Hokey Smoke Bullwinkle. Ive been so busy planning my first grow Ive over looked an important item. Ive decided to use a Grow Tent In my Bathroom. BUt it just now hit me how do I hook up exhaust and intake fans to a tent and be light tight. Ive relooked at the tents and some have tubes to hook into at the top Im assumening for the vent for the light useing duct tubeing for in light air. But I see nothing but holes for fans no way to block light....anyone have a plan for this or ideas>

A good tent will have port socks that extend into the tent with draw strings to close them up.

I seen the tube with draw strings but if you draw em close how do fans exhaust or intake. If you leave it open the light gets in. From what I seen anywyas....Ill pay for a good tent not a problem but all seem the same way. Anyone use a tent that has it figured out?

The draw strings are to take up the slack around the duct so it is light proof.

You need to use an inline for exhaust, and a passive intake. Use ducting on both, bam light proof. I have the GrowLab dr60 and its light proof 100% using this method.
