Yes, we own the house and its paid for. I already vent out a window. What I’m trying to accomplish is complete stealth. The bathroom exhausts already vent up into the attic. The attic itself is vented as well. The wood-burning stove already vents out the top of the roof so we’re not interested in renting anything else out the top of the roof. Thankyou for your input.. Here Where I am from the summers are very long very hot sometimes 102° and very very humid. I’m doubting venting in the attic will be a game changer.
013 & Jerry as always gave out some great information.
I would never vent into my attic. One bad run in the tent where you get some mold or mildew will then be pumped into your attic. I'm sure you can see where that could be problematic.
If this is a long term grow, can you sacrifice half a window? You can design and build something that fits into the window, has nice looking vent covers, and is movable. The vent covers are still in a box somewhere buy hopefully this sparks an idea
