We like to think about new ways to solve problems bonsai artists have, simple to intricate - in this case, super simple! Plastic drainage screens can lack rigidity needed for the job, so for the first time ever (to our current knowledge!) we are offering heavy duty, anodized aluminum, drainage screens for bonsai containers.
Each screen is CNC laser cut and then anodized clear to prevent oxidation of the aluminum. They are reusable over and over, no waste!
Our heavy duty anodized aluminum drainage screens come in two sizes, 1.50" and 2.25" squares. Drainage screens available here: 1.5" Screens & 2.25" Screens
Here is a technique I developed using our new rigid screens on a pot that doesn't have wire tie down holes, no drill needed.
