Hi everyone,

We recently bought a house built in the 70's with a really great indoor planter built into the foyer. There are large windows and a skylight above - plenty of light. But the planter is sealed tight with rubber - no drainage possible. It is roughly 2ft deep and 4'x3' in size.

I'm hoping for some advice on how to prepare this drainless planter? Should I put pebbles and sand in the bottom? Any type of soil better than another (someone had advised me to go to a hydroponics store and get soil there)? I'm not much of a gardener as of yet so any advice would be greatly appreciated!

Thank you!
Melissa
