Indoor gardening is the act of growing plants within an enclosed space, whether it be a house, an apartment, an office building, or a restaurant.
I would argue that indoor gardening is for more than just ornamental purposes. Many people choose indoor gardening because they may not have the option to garden outside. This could be because they live in an apartment, have a yard that is not ideal for gardening, or it is too cold for them to garden outside for majority of the year.
As more and more people begin to live in small homes in cities, and people are becoming increasingly concerned about the safety of the food they eat, indoor gardening is becoming a more popular option. However, indoor gardening is not easy, and more companies are creating technology that will make indoor gardening easier.
