How Many Plants Grow in a 4x4 Tent

The number of plants you can grow in a 4x4 tent depends on several factors, including the size of the plants, the growing method, and your local regulations. However, if you're growing small to medium-sized plants, such as cannabis, herbs, or vegetables, you can typically fit between 4 to 9 plants in a 4x4 tent. This allows each plant to have sufficient space for growth and access to light.
