This is an excerpt from the Cannabis Encyclopedia, Chapter 4, Cannabis Life Cycle. It outlines the basic possibilities for an outdoor cannabis gardener. Outdoor growers in warmer climates can grow a total of two crops every year, and three crops if they grow ruderalis-dominant varieties.
Typically, outdoor gardens are planted in the spring and harvested in autumn. By applying information from this chapter, outdoor gardens can be harvested two or three times a year within 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.
March 1 – Move bushy, well-rooted 1- to 2-foot tall clones and seedlings into a full-sun-heated greenhouse.
March 1 – Long nights will induce cannabis to flower.
March 15 – Remove male plants; male flowers distinguish male plants.
March 15 – Transplant clones and female seedlings into large containers.
March 15 – Move outdoors in mild climates – may need to cover on cool nights.
April 15 – Darken plants after 12 hours of daylight if flowering slows.
May 30 – Harvest smaller buds that received less-intense spring sunlight.
This auto-flowering 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!
Mid-summer Crop – 70–75 days
May 1 – Start ruderalis-dominant (super-auto-flowering feminized) variety indoors.
May 15 – Transplant auto-flowering feminized variety to 3-gallon (11.3 L) containers.
May 21– Transplant strong, healthy plants to outdoor garden.
June 1 – Female flowers are visible.
July 15 – Harvest 3 to 3.5 ounces (85–100 gm) of dried flower buds per plant.
Pure Indica/Sativa and Indica/Sativa Crosses
March 1 – Plant clones and seedlings indoors.
May 1 – Move bushy 1- to 2-foot-tall clones and seedlings outdoors in temperate climates.
May 1 – Pre-flowers appear; remove male plants.
June 1 – Move bushy 1- to 2-foot-tall clones and seedlings outdoors in all climates.
August 1 – Flowers start to form; remove any “surprise” male plants.
September – Harvest a large crop from big plants.
Spring-planted autumn crop – 210 days. 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.
