Settings for grid bottom

Hi there,

I have to print a pot for my bonsai, I want that the bottom is a grid for water flow, so I put 0 as a bottom and top layer, but also the top of the pot is now without layers.
There is any way to avoid this ?

Right click on the pot and use a height range modifier and adjust your wall loops and settings as needed.

Top, of course is functioning.
Thank you so much
