This is an excerpt from The Cannabis Encyclopedia, Chapter 4, Cannabis Life Cycle. It outlines the basic possibilities for an indoor cannabis gardener. Notice that if the crops were cycled every 60 days that it takes plants to flower, a total of 6 crops could be grown every year!

Indoor Gardens
Maintain mother plants and clones 18 to 24 hours of light daily. Induce vegetative plants to flower by providing 12 hours of uninterrupted darkness and 12 hours of light every 24 hours. Once the dark/light schedule has been set to 12 hours dark and 12 hours light, most varieties of cannabis will flower and can be harvested in 60 to 90 days.
First Harvest
Indoor Spring Crop – 90 days
January 1 – Move well-rooted 12- to 18-inch-tall (30–45 cm) female clones into room under 18 to 24 hours of light.
January 21 – Transplant clones into 3-gallon (11 L) containers.
January 30 – Induce flowering with 12-hour days and nights.
February 7 – Take cuttings and start the next crop of clones. Give clones 18 to 24 hours of light.
March 30 – Harvest first crop.
The garden on the right is about a week ahead of the garden on the left and will be harvested a week earlier.
Second Harvest
Indoor Summer Crop – 90 days
April 1 – Move well-rooted female clones into room under 18 to 24 hours of light.
April 21 – Transplant clones into 3-gallon (11 L) containers.
April 30 – Induce flowering with 12-hour days and nights.
May 7 – Take cuttings and start the next crop of clones. Give clones 18 to 24 hours of light.
June 30 – Harvest first crop.
The plants on the left will be ready to harvest in about a week. The plants on the right are about 2 weeks into flowering and will be harvested in about 6 weeks.
Third Harvest
Indoor Autumn Crop – 90 days
July 1 – Move well-rooted female clones into room under 18 to 24 hours of light.
July 21 – Transplant clones into 3-gallon (11 L) containers.
July 30 – Induce flowering with 12-hour days and nights.
August 7 – Take cuttings and start the next crop of clones. Give clones 18 to 24 hours of light.
September 30 – Harvest first crop.
Plant a spring crop in warm climates. Diminished sunlight intensity produces smaller buds, about half to three-quarters as big as others. If plants get cold at night, growth slows.
