Marijuana Seed: the mature, fertilized, ovule of a pistilate plant, containing a protective shell, embryo and supply of food: A seed will germinate and grow given heat and moisture.
Marijuana is normally grown as an annual plant, completing its life cycle within one year. A seed that is planted in the spring will grow strong and tall through the summer and flower in the fall, producing more seeds. the annual cycle starts all over again when the new seeds sprout the following year.
The seed has an outside coating to protect the embryo plant and supply of stored food within. Given favorable conditions, including moisture, heat and air, a healthy seed will germinate. The seed’s coating splits, a rootlet grows downward and a sprout with seed leaves pushes upwards in search of light. A seedling is born!
The single root from the seed grows down and branches out; similar to the way the stem branches up and out above ground. Tiny rootlets draw in water and nutrients (chemical substances needed for life).
Seeds can and should be stored in a refrigerator if they are not going to be used right away. The best storage method is to place seeds in a film canister with a few grains of rice (uncooked rice will absorb moisture). Place canister with contents in the refrigerator and they should have a shelf life of two years or more. The longer you wait to use your seeds, the greater the chances of germination rates lowering. If you wish to store for longer periods of time, then you can freeze them but make sure they are well dried before doing so.
Fat Leaves and Short Bush = INDICA
Thin Leaves and Tall Bush = SATIVA
Sativas are just about the opposite of Indicas. They are tall, thin plants, with much narrower leaves and grow a lighter green in color. They grow very quickly and can reach heights of 20 feet in a single season. They originally come from Colombia, Mexico, Thailand and Southeast Asia. Once flowering has begun, they can take anywhere from 10 to 16 weeks to fully mature. Flavors range from earthy to sweet and fruity. Sativa’s higher THC than CBD equals cerebral, soaring type of high, more energetic which can stimulate brain activity and may produce hallucinations.
Sativa plants are taller, take longer to mature, have less chlorophyll and more accessory pigments (accessory pigments protect the plant from excessive sunlight). As Sativa strains have less chlorophyll than Indica they take longer to grow, mature, and require more light.
Sativa typically takes longer to germinate and flower also, and grows more gangly then Indica breeds.
Yield is usually lower than Indica, but is very potent. Thai Sativa grows taller and has a longer flowering period, so they are better suited for outdoors.
Indicas originally come from the hash producing countries of the world like Afghanistan, Morocco, and Tibet. They are short dense plants, with broad leaves and often grow a darker green. After flowering starts they will be mature in 6 to 8 weeks. The buds will be thick and dense, with flavors and aromas ranging from pungent skunk to sweet and fruity. The smoke from an Indica is generally a body type stone, relaxing and laid back. Indica’s higher CBD than THC equals a much heavier, sleepy type of high. Indica plants have a heavy, stony high that is relaxing and can help different medical problems.
Indica yield is usually higher than Sativa, and shorter growing season. Better for indoor growing, because they don’t get as tall.
Indica plants are short, bushy, mature early, have more chlorophyll and less accessory pigments (accessory pigments protect the plant from excessive sunlight). As Indica strains have more chlorophyll than sativa they grow and mature faster.
Combining different indicas, different sativas or a combination thereof creates hybrids. The resulting hybrid strains will grow, mature and smoke in relationship to the indica/sativa percentages they end up containing.
Here is a quote from Hilary Black of the British Columbia Compassion Society:
“Indica and Sativa are the two main varieties of the cannabis plant used as medicine. There are many strains that are crosses of those two varieties. Within each of those varieties and crosses there are a huge number of individual strains, each with a different cannabinoid profile and effect. According to anecdotal evidence, the Indica strains are a relaxant, effective for anxiety, pain, nausea, appetite stimulation, sleep, muscle spasms and tremors, among other symptoms. The Sativa strains are more of a stimulant, effective in appetite stimulation, relieving depression, migraines, pain and nausea. We are now aware of specific strains that are effective for specific conditions and symptoms.”
