Marijuana Seed Strains: An Introduction

Top 9 Seeds here at HowtoGrowMarijuana.com


Marijuana or Cannabis Sativa (C.Sativa var. Sativa)

There are two key types of marijuana strains (cannabis) – Sativa and Indica. Each strain has its own unique properties and characteristics which will vary the strength, yield, size, type of high and growing conditions required. Depending on how you want to cultivate and grow your plants knowing about these strains and their traits will be a great help in deciding the variety for you! This is the original strain which originated in Asia, The Americas and Africa. Depending on where the original strain came from they will vary a little but all tend towards similar traits. These are, they grow tall and leggy in statue, with loose buds and more sparse flowers when grown indoors. These marijuana strains grow very fast and can take up to four months before buds form and harvest. The trade off of this is; strains are very potent with a high THC – CBD ratio giving a soaring, energetic “speedy” high. Sativa plants also have the advantage of not tending to be as strong in their aroma which can be beneficial when growing in less conspicuous environments. The flavor is often more sweet, fruity and spicy. More about Cannabis Sativa.

Marijuana or Cannabis Indica (C.Sativa var Indica)

These marijuana strain varieties originated in India and Pakistan and are highly prized by many growers and breeders for their squat, bushy growth, tightly packed buds, stout stems and compact root systems. They range in shape from a rounded bush to a pine like shape. The leaves are usually of a much darker shade of green and can even turn a purple color in some strains. As they are able to process light more efficiently from greater quantities of chlorophyll they tend to have shorter grow times. This will also lead to the buds being denser and more blocky. The high from these plants is like their smell strong and heavy, with a real body stoned lethargic hit. This is caused by a higher CBD – THC ratio. The flavor is far more intense and acrid often having a skunky / musky quality. More about Cannabis Indica.

Auto-flowering Marijuana Seeds

The first auto-flowering marijuana seeds came onto the market many decades ago now and have been a huge success ever since. Autoflowering seeds begin their flowering automatically when they reach a given level of maturity, regardless of the photoperiod. In comparison 'normal' seeds will continue to grow until their lighting is reduced enough as a replication of falls arrival. Most of the auto-flowering marijuana seeds are a hybrid of Indica and Sativa and can start around week three.  More info on auto-flowering marijuana seeds

Feminized Marijuana Seeds

Feminized seeds give a tremendous advantage under artificial lighting, outdoors or in the greenhouse. They will deliver optimal quality as well as showing the strongest characteristics of the strain. The quality, taste , flavor and potency (THC/CBD %) of marijuana produced from feminized seeds is significantly higher than those produced by non feminized seeds. Although these seeds will produce 99% feminized plants , there are other factors that will also help increase the quality and the likelihood of female plants.

Indoor / Outdoor Marijuana Seeds

Whether a plant is designated “indoor” or “outdoor” is based around the optimum growing conditions for that strain. As most varieties of marijuana come from plants that naturally thrive in a tropic or sub tropic region, this is normally the preferred medium for the majority of plants. Of course, as not everybody lives in these types of climate, different marijuana strains have been bred with different tolerances to heat and cold, or the strength of sunlight falling on them etc. With this in mind in more northerly climates (Holland, Canada etc) those plants that need more heat and light are labelled as 'indoor'. Whereas plants that have been bred to endure cooler climates can be grown outdoors such as Alaskan Thunder Fuck. If you live in a temperate climate than most indoor strains can be grown outdoors and vice-versa. More about the best marijuana seed strains.


THC – Tetrahydrocannibinol, the physiological ingredient which is the main source of the “high” effect felt from Cannabis. Most plants will contain between 5-15% THC but some newer strains are now pushing 20%. This does not necessarily mean that it is better as there are other factors that affect the smoke, including taste, aroma and CBN level. CBD – Cannabichromene, the chemical that usually prolongs the high and gives the "high" effect.
