haha im aware of that

god id love to live in a blimp hanger on a side note...

i can vent the space whenever i want, and co2 would be constantly pumped in...but for the most part it would stay more or less sealed, aside from whatever way i find to insert the 2 duct tubes into the room...

which im not really sure how to do yet. there is a small 1x1 opening hinge door at the bottom of it and ill run them both through there....but i have no idea how to fill in the space between the duct tubes since theyll be in a square opening.

i ussually flood the op with a fan using that square hole but since ill be putting 2 duct tubes there that will pretty much take up the space ill have to find a new way to exaust..
