      SUPER SILVER HAZE Feminized Cannabis Seeds (T.C.S.)

      Super Silver Haze Cannabis Seeds Feminized

      Key Features: A classic haze variety that is better for indoors in northern latitudes.

      Super Silver Haze is a genuine classic cannabis strain with a long history; winner of 3 consecutive HTCC awards in 1997, 1998 and 1999. It is a combination of Skunk, Northern Lights and Haze.

      Super Silver Haze is probably the most indica-leaning of the famous sativa strains in terms of its effect. It is another plant that can get rather tall and unwieldy if allowed to. In order to preclude this it is recommended to use SCRoG or LST indoors and to give a reduced vegetative period. Indoors with 10 - 11 weeks flowering it is possible to produce a harvest of 800 gr/m2. Outdoors in equatorial, tropical, subtropical and temperate climates it can produce up to 1500 gr/plant for mid-October in northern latitudes.

      The THC production of Super Silver Haze is 19.11% with low CBD and CBN of 0.17% and 0.74% respectively. It hits fast, strong and is a very long-lasting high that will eventually induce an advanced state of relaxation. Therapeutically it has been found to be very effective in the stimulation of appetite and in controlling pain.

              TCS SPECIAL Feminized Cannabis Seeds (T.C.S.)

              TCS SPECIAL Feminized Cannabis Seeds

              At Toronto Cannabis Seeds we decided to bring you a hybrid at a low-cost price. Perfect for a first-time grower who doesn't want to invest too much in his experimental growing. This TCS Special is a classic skunk that grows with ease, doesn't stretch too much and can be harvested in 7-8 weeks.

              It’s a cross between two spectacularly resinous strains but with very different nuances. Like most Indicas, TCS Special is a compact plant although care is needed in SOG systems so that the plants don’t get too tall as small or medium-sized column-shaped plants are best. Very abundant flowering with very swollen resin-filled calyxes.

              Produces few leaves, which combined with the fact that this is one of the most rapid strains on the market, makes cultivation very simple and for bumper yields. Very fruity smell with acidic notes; like strawberry or wine gums. The smell becomes much more intense and penetrating as the leaves are broken apart. The sweet, fruity taste has very strong Skunky notes. The effect is very strong and quick and mostly cerebral.
