i'm not sure i really understand either, but I think your saying that you want to put a bag inside the bucket so you can just pull out the bag and not have to dump it? Aren't the roots gonna be hanging into the bag making it hard to remove it? why dont you just drill a hole in the bucket and make a drain. kinda like a waterfarm that way you can see how much water is in the bucket too.

Check out the blue tube. try making the drain like that. Then you wont need a bag.- The House
The House Reviewed by The House on . Question about DWC In using the 5 gallon bucket setup, airstone, etc. in a cabinet setup, it seems it would be a hell of a lot easier to insert a black hefty bag into the bucket and then fill it, then when time for water change just fill another bag up, remove the old one, drop in the new one, throw your old stuff out. Would this be possible or has anyone tried it?Anybody see anything wrong with it? Would this work? Also would allow for a darker bucket to reduce root rot, am i correct here?
