The size of your grow room will determine many things, such as the total amount of plants you can have growing at one time. However there is no rule that says your grow room has to be a certain size. Grow rooms can be rather small actually. There are even a few advantages of having a small grow room.
Growing in a Closet
Closet grows are very popular and offer growers the chance to grow with less light. Since the space is small, the amount of light can be small as well. The real challenge with a closet grow is keeping the air ventilated. If it is an option at all you will need to create some ducts for air ventilation and have a fan moving air through that duct.

A closet is a great place to grow a plant through its vegetation phase since you can use fluorescent lights for this. Fluorescent lights are good for small grow rooms because they do not get as hot and require the ventilation of an HID light.
