The last five years my main project has been updating Marijuana Horticulture. At first I thought it would be a basic update. Then, the more I researched and studied, the more I went off on research tangents. Most of the research, organizational work and writing have been a lot of fun. Other days I would sit and complete one repetitive task after another.
To give you an idea of the size of the new book I have listed the basic stats below.
Note: The new book has twice as many words and almost twice as many images as Marijuana Horticulture, Fifth Edition.
Format 8.5 x 11 inches
Here is an excerpt from the new book from Chapter 01, Cannabis Life Cycle.
This section outlines three different gardens in three different locations: indoor, greenhouse, and outdoor. The examples show different planting and harvest scenarios that use the natural advantages provided by each garden and the varieties grown. For more complete information about each type of garden, see chapters on Grow Rooms, Case Studies, Outdoors, and Medical Cannabis Varieties.
Maintain mother plants and clones 1824 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 6090 days.
Indoor Spring Crop 90 days
[Ch 01 DSC02640]
This indoor garden is growing under T5 fluorescent lights. The T5s are able to supply plenty of light for vegetative growth. The plants are in individual containers and are easy to move in the garden.
01 January Move well-rooted 1218-inch-tall (3045 cm) female clones into room under 1824 hours of light.
21 January Transplant clones into 3-gallon (11 L) containers.
30 January Induce flowering with 12-hour days and nights.
07 February Take cuttings and start the next crop of clones. Give clones 1824 hours of light.
30 March Harvest first crop.
Indoor Summer Crop 90 days
[Ch 01 0 IMG_6522]
The garden on the right is about one week ahead of the garden on the left and will be harvested a week earlier.
01 April Move well-rooted female clones into room under 1824 hours of light.
21 April Transplant clones into 3-gallon (11 L) containers.
30 April Induce flowering with 12-hour days and nights.
07 May Take cuttings and start the next crop of clones. Give clones 1824 hours of light.
30 June Harvest first crop.
Indoor Autumn Crop 90 days
[Ch 01 0 IMG_6515]
The plants on the left will be ready to harvest in about one week. The plants on the right are about two weeks into flowering and will be harvested in about six weeks.
01 July Move well-rooted female clones into room under 1824 hours of light.
21 July Transplant clones into 3-gallon (11 L) containers.
30 July Induce flowering with 12-hour days and nights.
07 August Take cuttings and start the next crop of clones. Give clones 1824 hours of light.
30 September Harvest first crop.
Greenhouse crops can be harvested two or more times a year, but most often greenhouses are planted in the spring and yield a single harvest in the fall. In cold climates, greenhouses must be heated. All greenhouses must be vented or cooled in warm weather. The basic harvest scenario below shows how to harvest three greenhouse crops every year.
Greenhouse Spring Crop 90 days
[Ch 01 Tropic IMG_9487]
This Mexican greenhouse needs shade cloth and supplemental lighting at night to keep plants in the flowering growth stage. The days and nights are between 11and 13 hours long all year round. This is the perfect photoperiod for flowering in cannabis.
01 March Move bushy well-rooted 12-foot-tall (3060 cm) clones and seedlings into greenhouse.
01 March Long 12-hour nights and short 12-hour days in spring signal cannabis to flower.
15 March Remove any male plants. To distinguish plants, look for male pre-flowers.
15 March Transplant clones and female seedlings into large containers.
15 April Darken greenhouse after 12 hours of daylight, until harvest.
30 May Harvest: The less intense sunlight will make for smaller buds than harvests later in the season.
Greenhouse Summer Crop 90 days

Black plastic is alongside this light depravation greenhouse. Every day the black plastic is pulled over the greenhouse to black it out and create a total of 12 hours darkness, which induces flowering in indica and sativa varieties of cannabis.
01 June Move bushy, well-rooted 12-foot-tall (3060 cm) clones and seedlings into greenhouse.
15 June Remove male plants; male pre-flowers distinguish male plants from females.
15 June Transplant clones and seedlings into larger containers.
01 July Induce flowering by blacking out (covering) greenhouse after 12 hours of light.
15 July Verify the gender of all plants. Remove any remaining males.
01 August Maintain flowering by covering greenhouse after 12 hours of light until harvest.
30 August Harvest a heavy crop of top quality medicinal cannabis flower buds that have received maximum levels of sunlight.
Greenhouse Autumn Crop 75 days
[Ch 01 Osona 008]
The small greenhouse protects flowering cannabis from regular rains and bad weather. The greenhouse also keeps plants a little warmer at night. More regular irrigation is necessary when growing large plants in small containers.
01 September Move bushy, well-rooted 12-foot-tall (3060 cm) clones and seedlings into greenhouse.
15 September Long nights and short days of autumn signal cannabis to start flowering.
15 October Medical cannabis flowers develop but low light levels limit growth.
15 November Harvest smaller buds that have received less intense fall sunlight.
Typically outdoor gardens are planted in the spring and harvested in autumn. Applying information from this chapter, outdoor gardens can be harvested two or three times a year in moderate to temperate climates. Transplanting clones and seedlings and harvesting a single crop is all that is possible in cold climates with a growing season of 90 days. Extra care must also be taken to protect seedlings and clones from harsh weather.
Mild Climate Spring Crop 90 days.
01 March Move bushy, well-rooted 12-foot tall clones and seedlings into full-sun heated greenhouse.
[Ch 09 Morocco 101_0287]
Plant a spring crop in warm climates. Diminished sunlight intensity grows smaller buds, about half to three quarters as big as others. If plants get cold at night, growth slows.
01 March Long nights will induce cannabis to flower.
15 March Remove male plants; male flowers distinguish male plants.
15 March Transplant clones and female seedlings into large containers.
15 March Move outdoors in mild climates may need to cover on cool nights.
15 April Darken plants after 12 hours of daylight if flowering slows.
30 May Harvest smaller buds that received less intense spring sunlight.
Mid-summer Crop 7075 days
[Ch 01 IMG_4246]
This little autoflowering feminized seedling is an example of how a germinated seed can grow into a mature plant ready for harvest in just 70 days and receive 18 hours of daily light!
01 May Start ruderalis-dominant (super autoflowering feminized) variety indoors.
15 May Transplant autoflowering feminized variety to 3-gallon (11.3 L) containers.
21 May Transplant strong healthy plants to outdoor garden.
01 June Female flowers are visible.
15 July Harvest 33.5 ounces (85100 gm) of dried flower buds per plant.

A complete 7-month-long season will yield very big plants when grown properly. These 10-pound (4.5 kg) plants received full sun all day long and grew in outstanding organic soil.

01 May Pre-flowers appear; remove male plants.
01 June Move bushy 12-foot-tall clones and seedlings outdoors in all climates.
01 August Flowers start to form; remove any surprise male plants.
30 September Harvest a large crop from big plants.
