I've seen proposals for something similar to the "deep-feed / deep-water" idea.
One scheme replaced your jug with a really big tin can, the other used a 4" or 6" diameter length of PVC.
They both had holes in the bottom, but they filled the tub / can / jug with manure, raw compost-makings, or finished compost.
The idea was that the water would leach out Good Juices while it perked through the compost.
Aerated, weak compost tea or manure tea would come out the bottom, near plant roots.
The proposal that urged putting raw scraps into the 6" tube made his underground holes big (like 1" or 1.5"), so that worms would be attracted and go in and out, carrying the compost to a radius of several feet as worm castings. . He called it something like spot-vermicomposting.
I forget whether they suggested putting a slow drip irrigation emitter at the top of the tube, but it sounds good to me.

But I haven't tried it myself yet.
