Okay.
I have a new design for you.
Use solid containers.
Hang as you described, or whatever works.
Drill one hole in the low point.
Feed a nylon wick (small rope) out the bottom corner of the pot.
Feed untill it wants to pour out the top.
The wick will slowly drain the pot's perched water table.
Guide the wick to your collection point.
Done.
Maybe.
Cheap, and Easy.
Feed once a day to saturation, let the media dry out as the wick does it's thing.
