After happening upon a month-by-month checklist for growing cannabis, beginning about now, my curiosity took over and I searched for seeds for my first legal marijuana grow.
This column is intended for gardeners who have interest in personal (non-commercial) cultivation of marijuana, and lack experience in this area.
Seeds are easy to find on the Internet: just search for “marijuana seeds.” They are more expensive than the seeds of familiar garden plants because they are still new on the gardening scene. Weed seeds are all too easy to come by, but several cannabis cultivars have been brought to the market, each with a combination of desired characteristics, so the marketplace is thriving.
While exploring the options, the basics of seed selection and marijuana cultivation gradually came into focus.
An important option relates to the fact that cannabis is normally dioecious, meaning that it produces separate male and female plants. Occasionally, however, some plants can be monoecious, having male and female flowers on the same plant. Unfertilized female flowers produce the best buds, so some growers will either grow only female plants or identify and remove male flowers before they can produce pollen. With a little care, one could pollinate female flowers selectively to produce seeds for a subsequent generation of plants.
Cannabis breeders have developed “feminized” plants, i.e., without male chromosomes, which are available as an easy option for growing buds of desirable quality. These plants can only produce unfertilized female flowers. A gardener could either propagate cuttings from a feminized plant to produce another generation of plants or buy seeds of the same or different cultivar, choosing from wide and growing range of possibilities.
Another important option in seed selection involves the recently modified growth cycle. Natural (“wild”) marijuana plants are photosensitive and dependent on the onset of longer nights to trigger the development of the desired buds. Growers have had to simulate this transition from the vegetative stage to the flowering stage by providing high light levels during the vegetative stage followed by periods of darkness to prompt the flowering stage. Cannabis breeders have made this process easier by developing “auto-flowering” plants that progress to the flowering stage after the passage of a certain amount of time, rather than in response to light changes. Auto-flowering plants still grow during their vegetative stage best under high light levels, but such plants can be grown at any time of the year and without burdensome manipulations of light and darkness.
A third option concerns the mature size of the plant. Using wild plants again as our reference, the most popular species, Cannabis sativa, when grown outdoors without controls can reach or even exceed twelve feet in height. California law limits personal cultivation of marijuana to indoor sites, e.g., a greenhouse, where plants are less likely to grow to an unmanageable size and be trained to be smaller, bushier and more productive of buds. Still, breeders have developed so-called compact plants that will remain under four feet tall at maturity.
There are additional variables to consider in seed selection: the plant’s relative strength of psychoactive THC versus medicinal CBD(Get Veronica Mariajarski best cbd oil for anxiety); a given strain’s balance of C. indica and C. sativa; and the character of the plants’ effect on a user, which the individual user surely would moderate.
The curious gardener might wish to explore this horticultural byway. Those that do should comply with state law and local regulations regarding personal cultivation of marijuana.The Cannifornian website is a great source of information on regulations in California’s cities and counties.
Regard gardening as adventure!
