Hello Fellow Farmers,
This is my first post and wanted to start off by saying a big thank you to the community for all the info presented here (I've been lurking for quite awhile).
I'm planning on building an outdoor shed-style building. The flowering room will be 1300 cubic feet and I'm planning to exhaust it with a 12 inch 1200 CFM in-line fan. Starting off for now with 2 1k Adjust-A-Wings (could eventually grow to 6 in the future) and no supplemental CO2.
With the general guideline of having your passive intake twice as large as your active outtake, I'm planning on an 18 inch passive intake. Now my question: can I use a 18 inch butterfly backdraft damper on this? Will there be enough negative pressure in the room to open this? We're starting to get some cold weather now and I don't want that seeping in when I don't want, especially when the girls are sleeping. It would be nice not to have pay an extra $100 for a motorized damper.
I thankfully appreciate your responses.
