Cannabis, also known as marijuana, has been used for medicinal and recreational purposes for centuries. In recent years, its cultivation has become more widespread as more states legalize its use. This article will provide an in-depth look at the various aspects of growing cannabis indoors.
Choosing the Right Strain
There are hundreds of cannabis cultivation strains available with differing characteristics. When starting a cultivation operation, careful consideration should be given to selecting strains suited to the grow environment and intended use of the crops. Popular medical strains include Charlotte’s Web, ACDC and Harlequin due to their high CBD content and low THC levels. Recreational users often prefer hybrids like Blue Dream, Girl Scout Cookies and Granddaddy Purple which provide a balanced high.
Setting Up the Grow Space
The grow space needs to meet certain criteria to ensure an optimal environment for plant growth. Areas must be dry, well-ventilated, have access to electrical outlets and remain secure and free from pests. Indoor grows commonly use sealed rooms in basements, attics, spare bedrooms or purpose-built structures like greenhouses. Soil vs hydroponic systems, lighting equipment and ventilation must also be selected and installed.
Propagation and Germination
New Cannabis Cultivation plants are typically grown from seed. Seeds undergo a germination process where they are soaked in water or planted directly in soil. Within a few days, the seeds begin to sprout roots and the plant stem emerges. Seedlings are then transplanted into larger individual containers as they grow their first set of leaves. Clones, cuttings from mother plants, can also be used to propagate new plants vegetatively.
Vegetative Growth Phase
During the vegetative stage, plants focus energy on building their root structure and developing foliage. Growers manipulate light cycles to encourage new growth, usually keeping plants in a 18/6 hour light/dark cycle. Proper watering, fertilizing and training techniques like topping and Low-Stress Training (LST) are utilized to develop a strong framework before flowering begins.
Flowering and Bud Development
The shift to flowering is initiated by changing the lighting to a 12/12 hour cycle. Cannabis plants use this photoperiod cue to start producing flowers, or buds. Brightening colors and formation of resin glands signal the transformation from vegetative to reproductive growth. Under the right conditions, dense calyxes filled with THC-rich trichomes rapidly expand over the following 6-8 weeks.
Harvesting and Drying
Cannabis crops are harvested when most pistils have turned from white to orange and trichomes appear cloudy or amber in color under magnification. Whole plants are cut at the base and hung upside down in a dark, well-ventilated area to slowly dry over 5-10 days. Branches are then trimmed and manicured to prepare the finished buds for curing, testing and storage.
Closing Thoughts
With expanding commercial cannabis cultivation, growing methods and genetics are continually improving to produce higher yields of safer, medicinally beneficial products. As more research is conducted, techniques will advance further to mitigate risks while maximizing benefits for users. Overall, it is fascinating to observe the plant’s life cycle from seed to harvest through an organized indoor agronomic process.
