It will be good for a few years. The barrel will rust. The lava will
need cleaned some day, I scraped the skin off my fingers cleaning the
lava out of mine. (similar design)

the barrel is actually plastic. I have heard similar statements about
problems cleaning the lava rocks though, i guess we will see when the
time comes.

Plastic is better. Is the top open or closed. Mine is open, I grew
iris in there one time, cannas another time. BAD idea. They welded
the rock together. I have water hyacinths in mine now, they work well
except when they plug up the outlet.- Hide quoted text -
