So i found a roll of weed blocker and cut some out and tested to see if it drains water well. i put it under the sink ran some water under it and it doesn't drain the water very fast. it kind of sits there and lets a drop of water through once every minute or so. Should i use this stuff or should i use something else? I saw some people use nylon tulle, and my sister has a ton of that stuff. Would this be better for a false bottom?
