High THC Strains

For thousands of years mankind has smoked, inhaled and ingested plants to feel altered states of consciousness. Marijuana is probably one of the most commonly used and accepted forms, together with several forms of fungus and mushrooms.

The resin that forms on the buds and leaves contains a chemical known as Tetrahydrocannabinol, THC for short. This is the principle psychoactive constituent of Marijuana and responsible for the feelings of euphoria and altered states of consciousness associated with feeling ‘high’ or ‘stoned’.

Natural, Land-race Marijuana strains generally contain between 12% – 14% THC content. However, with demand for stronger, more powerful Marijuana increasing over the years, many Seed Banks offer a selection of High THC Marijuana seeds for sale.

Extremely powerful and potent, these new, hybrid strains contain a mix of both Indica and Sativa genes, inducing soaring ‘highs’ and ‘couch-locking’ effects. Twice as strong as natural Marijuana, they have been created purely for recreational use and often contain very low levels of CBD.

Marijuana seeds can be planted outdoors from the middle of Spring and cultivated around the end of September. Although these High THC strains will grow well in a warm, sunny climate, they produce their best quality yields when cultivated indoors under controlled conditions.

With demand for edibles and concentrates increasing, these High THC strains are often used to produce premium quality products with extremely high potency levels.
