Light deprived weed, or light dep for short, is a common process used to grow cannabis. Growers use this technique to trick the plants into thinking the flowering season is beginning sooner than they think. Light dep can be practiced with indoor, outdoor and in a greenhouse setting. 

Most states restrict private growers to 6 plants, which can take up some space, so outdoor and greenhouses are the most popular. Setting up a cannabis light dep system outside is a cost-effective way to get the best yield out of your crop. The size of light dep cannabis is often underestimated and may become unmanageable in indoor setups if the strain in question grows particularly tall or wide.
