How big of an area is needed to dry 3 or 4 pounds?

My room is 18x11'. The flower room is 11x11' leaving 7x11' for veg/clone/mothers. I'd like to wall off a portion, say 2-3x7' for drying running wires at different levels 7' wide. Would this be enough room to dry 3-4 pounds?

Well if it was all trimmed up and on screens, then yes, more then enough room, if your going to be hanging the plants upside down, untouched, then you might be pushing it. Takes quite a few indoor plants to produce 3 or 4 pounds.

You can crank out well over 4 pounds in that room all day long.

After much fiddling around I built a drying tent out of 2x2 and panda film. It is around 5' long 3' deep and 8 high. Dried about 5 in it. I made it so it can collapse so I just roll it up and put away when I'm done
