If you’re growing cannabis indoors, you’ll want to switch the light cycle from the vegetative stage to the flowering stage when your plants have reached the desired size and are mature enough to start producing flowers. Typically, this occurs after about four to six weeks of vegetative growth, depending on the strain.

To switch from the vegetative stage to the flowering stage, you’ll need to adjust the light cycle to a 12-hour light/12-hour dark cycle. This signals the plant to start producing flowers.

It’s important to note that different strains of cannabis may have different requirements for light cycles, so it’s always a good idea to research the specific strain you’re growing to determine the optimal light cycle for that strain.

Additionally, outdoor cannabis plants will naturally start to flower when the days start to get shorter in the fall, so you don’t need to adjust the light cycle for outdoor plants.
