Individuals with a valid medical marijuana card or their caregiver can grow cannabis to use medicinally for their qualifying condition. 16 states have legalized medical marijuana and each one allows for different amounts per patient.
Whether grown indoors or outdoors, cannabis has the same growth requirements. The basic needs are light, air, water, nutrients, a growing medium, and heat. When grown indoors, the light needs specific intensity and spectrum and the air needs to be warm and rich in carbon dioxide.
Usually marijuana is grown annually and has multiple growth stages. They are distinct and termed germination, seedling growth, vegetative growth, pre flowering, and flowering.
Germination entails hormone activation in the seed’s outer durable coating. The seed’s embryo expands and its coating splits. This permits rootlets to grow downward and a sprout with leaves pushes up looking for light. This stage takes anywhere from three to seven days.
During seedling growth, downward growth of the root occurs and branches are created. These small branches pull in nutrients and water. The roots are able to anchor the plant in the growing medium. Lots of light, about 18 hours a day, is necessary during seedling growth.
The vegetative growth stage needs a lot of light, fourteen to twenty four hours daily. A water transport system is grown by the developing roots, and food storage occurs. The root parts that absorb the nutrients and water are the single celled root hairs, and unfortunately they tend to be easily damaged by air, light, and human carelessness during movement.
The stem also elongates, producing new buds with the lateral buds turning into branches or leaves. The central bud carries growth upwards. The stem carries the water and nutrients from the delicate root hairs to the buds, leaves, and flowers. The stem should not be bound too tightly with strings or tie downs.
The stem also gives support to the plant, and if the plant is situated outside then elements like rain and wind strengthen the stem by stiffening up cellulose. Indoor plants do not receive such stimuli, so they do not stiffen up and it may be necessary to place a stake for support.
Photosynthesis occurs as plant leaves expand and food is manufactured.
After the 4th week of vegetative growth, pre flowering occurs. This happens between the 4th and 6th node from the bottom and are either female or male. Male plants have a considerably lower cannabinoid concentration, so they are often destroyed.
Flowering is triggered in most commercial cannabis varieties by 12 hours of light and 12 hours of darkness every 24 hours. Flowers form during the last growth stage and if the females flowers are not pollenated, they develop without seeds – called “sinsemilla”. If pollenated by a male, female flower buds develop seeds.
If the plant doesn’t get pollenated for a few weeks, THC production peaks in the female unfertilized sinsemilla. With fertilizing, the female matures its seeds, which then either fall off or get collected for subsequent planting.
