Every garden has a footprint. These are the dimensions of the area in an indoor garden that require light, so thing like work areas and paths used to access plants are not included. In an enclosed area such as a tent it is generally the entire dimension of the tent.

Selecting the correct size light in terms of power or wattage is critical to your success as an indoor gardener. If you size too small you will not have the yields or quality you desire. If you select too large of a light you will end up wasting energy and possibly have issues with keeping your environment cool.
