For best bonsai results, water them only once the soil is dry. The drainage holes in this model allow you to saturate the soil and let it drain, then return it to the leak tray/stand.
I recommend a high infil if not 100%, as this needs to be mostly water tight.
0.2mm printing works well for me.
Enjoy your micro bonsai on your desk.
