I've just had the bubble bucket craze hit me upside the head, so I figured I'd make an oddball bubbler out of an old Bali Shag tin.

I'll put the steps I followed down, and the pics to accompany in order in the attachments.

1. Clean out Bali Shag container and waterproof the bottom part with epoxy.
2. Drill a hole large enough to run air line, about an inch down from the top of the can. (No photo)
3. Install an airstone or make your own (I did this just by sticking air tube into a slit I made in a block of foam, then epoxy around to seal it together.)
4. Make a net pot by cutting slits in a 4" pot. (I use a dremel with a drilling bit as a piercer and router.)
5. Run airtube through the hole, put airstone in place at bottom.
6. Set net pot on top.

VOILA!

Well, so far it hasn't sprung a leak. Everything is still bubbling away, and holding up. I think I might actually test this out with one of my African basil clones.

Lol, I think it's brilliant personally. It's not gonna have much room for root growth, but pretty cool idea. I was thinkin about something like this myself, just for shits and giggles. Just for small little autos or somethin...

It'll work sure, provided the epoxy covered the can well enough and provided the epoxy doesn't leach toxic chemicals. It's more than enough for anything under 3'.

You have more root space in that than I do in this:

That's a nice looking plant in such a tiny container!

The epoxy I use is absolutely non-water soluble so there shouldn't be anything leaching out into the water, at least once it had fully cured.

So it worked, until the water bubbled up to the level of the air line, and started soaking into the cardboard that way. then it burst.

Lesson for next attempt: Make sure the entire thing is coated with epoxy and all holes are sealed in place! It would have worked otherwise!
