Ultra Lemon Haze was created by crossing the Cannabis Cup winning Lemon Haze with a select Sour Diesel developed in northern California. This was then crossed with our Auto #1 to produce a stable strain that is truly unique. These genetics and the resulting strain have created something incredibly special which has made it a favourite choice. The Super Lemon Haze was a multiple cup winner for good reason and these traits have carried through into Ultra Lemon Haze. Sativa dominant, the buds are long and dense with typical sativa shape shade leaves. The smoke is spectacular and the stone distinctly psychedelic with an excellent balance between a physical body buzz and soaring cerebral high.
Ultra Lemon Haze can be grown well both indoors and out, but indoors requires a good level of control and management to obtain the best results. Due to the dominance of the Sativa genes and the lower percentage of Ruderalis this is not a standard autoflowering variety. For optimum yield and maximum psychoactivity (THC content), 90+ days are recommended. Indoors, special care must be taken. Unlike other autos the best photoperiod for Ultra Lemon Haze is 12-16 hours. It is also best to change from vegetative nutrients to flowering nutrients at week 5/6 to ensure the best crop. The extra time and care required for Ultra Lemon Haze will bring outstanding rewards and will leave you wanting to make this a regular addition to your grow.
