I have a student who refuses to buy or make screened cinder. He thinks his extensive collection will be fine in it. A very temperate climate here in Hawaii with lots of rain and no extremes. I'm in disbelief and considering giving him the boot. Sure, roots will fill the bottom of the container and the fines will clog the screen, but still. He stubbornly refuses to do any research and is stuck in his ways.
