I see, ya that makes sense. thanks!
What are ur guys opinions on doing it the same way I do... Cutting wood for the window frame with holes for intake and outtake but you need to cover the wood so people can't see the wood and holes for vents? I use just a tapestry that's light enough for airflow but you can't see through... u guys have any alternatives to a tapestry to put in the window to cover but also have good airflow? I would like to have a bit more airflow than the tapestry allows, especially for a new 4k grow...
