Indica dominance plants generally tend to be smaller, wider, more productive with a more robust plant structure and a shorter distance between nodes than sativa. Sativa plants are often more slender and high than indica. The flowers of the indica varieties are most often more dense, thick and heavy than the flowers of sativa varieties, which are more airy and elongated. The effect of Indica varieties is recognized to be more sedative and relaxing than that of sativa. These are logically more energizing, psichoactive and stimulating.

    Indica-dominant plants tend to have the following characteristics:

    - small ;

    - wide ;

    - highly productive;

    - robust plant structure;

    - shorter distance between nodes;

    - dense, thick, heavy flowers;

    Feminized cannabis seeds produce 99% of female cannabis plants. They allow the optimization of the filling of the space, as you will not need to eliminate male copies during flowering. They therefore constitute an ideal first choice option for many cultivators with a small indoor or outdoor space.

    Collection cannabis seeds with autoflowering are a type of collection seeds made up of different “ruderalis” genetics. They need a single photoperiod during the entire interior culture cycle, that is to say 20 hours of continuous light. They have the particularity of flowering independently of the photoperiod to which they are subjected. They are also called "automatic varieties" because they flourish automatically after about 3 to 4 weeks of growth, both indoors and outside.

    Regular collection cannabis seeds produce around 50% male plants and 50% female plants.

    Autoflowering collection cannabis seeds have rapid development. They flourish automatically, without any influence of the photoperiod, after only 3 to 4 weeks of growth. It is therefore not necessary to use an 18/6 hours photoperiod for growth and 12/12 hours for flowering. On the other hand, any photoperiod variety, imperatively requires a period of growth (18/6 hours) and a flowering period (12/12 hours). Thank you for reading and following the publications of the different articles of our blog for more information.

    The varieties of cannabis "Fast Flowering" are rapid flowering varieties, but requires for their evolution two distinct photoferiods. For growth, they need 18-hour light and 6 hours of darkness. For flowering, they require 12 hours of light and 12 hours of darkness, like any variety with photoperiod. Autoflowering varieties, in turn, flourish automatically 3 to 4 weeks after their germination, without any influence of the lighting duration to which they are exposed.

    We advise you to place them in a hermetic packaging away from moisture, from the air and light. Then place them in the lower part of your refrigerator (vegetable tray, temperature 6 to 10 ° C). At this temperature the humidity of the air remains relatively low. These are stable and reliable conservation conditions that allow for a long-term storage. They will thus maintain a high germination potential.

    In previously mentioned conservation conditions, your collection cannabis seeds will retain a high germination rate for about 6 to 10 years, without any problem.

    THC or tetrahydrocannabinol, is the main psychoactive cannabinoid present in a large set of cannabis varieties.

    CBD or Cannabidiol, is a non-psychoactive cannabinoid whose benefits are increasingly recognized at different levels.

    Cannabinoids or phytocanbinoids, are a group of chemicals that activate the different receptors of the endocannabinoid system, present in the human body as in many mammals.

    The terpenes are natural molecules, present in the cannabis plant as well as in many other plants on the planet. Terpenes are directly responsible for the profile and the aromatic and taste intensity of cannabis. It seems that they also act at the level of the effect, in symbiosis with the different cannabinoids present in the plant. They are very present in our diet as in our daily environment.
