Sides of tent collapsing in? Cheap easy fix.

Hi all
The sides of my tent kept collapsing in due to the venting pressure of my fan.
I was going to add an extra pole but found an easier way.
I made a quick fix for a buck.
I ordered a Tarp Clip off of ebay for $1
Gained a few inches of grow space
before

after it give me an extra few inches.

now for some bud porn.
Two weeks left as of today

Cheers

I use bamboo poles to stop the sides from being sucked in.
