When it comes to indoor houseplant pots, you can have a lot more fun with the material you choose as they won't need to withstand the outdoor conditions. You'll also be decorating with plants, so you can pick colors and materials that work for your interiors. However, you need to make sure you go for the more porous option. Ceramics and clay will dry more evenly than in plastic pots.
Even though plastic is the cheaper option, there is nowhere for the water to escape to and plastic keeps the water in for nearly double the time as clay. If you do go for plastic, make sure the soil is held by another plastic pot with drainage holes on the inside.
