hiy gyspy. that was a pic before i widened the holes properly but you may be right. i did stick it on the exhaust end earlier and the flow 'seemed' adequate. now its in the tent flow still seems fine. still negative pressure but i had that before making the holes bigger.
if it isn't enuff then i will start with making the holes even bigger, then drill new holes and then just cut out a 100mm hole. if that still isn't enuff then i guess it's spending time agian.

Oh... you can make this work for sure... no problem...
If I was to make more wholes.. I would drill them on the hood itself... but that reflective material would be best served by a slit that can be pried open... like the original holes...
I would also consider a piece of glass sealing the bottom of the hood...
But for now, as long as the fan is not being OVERworked, and the temps stabilize, you are golden...
And you will notice an explosion of buds...
Try not to look at the girls too much for the next week...
do your chores and all.. but just make it apoint not to look too hard at the buds...
wait a week and be amazed... ahahahahaha....
Cheers ....
and a bong hit of course....
