To create Ultra Lemon Haze we crossed 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 one of our favourites. The taste is of sharp citrus, lemons and pink grapefruit, whilst maintaining the fuel like undertones of the Sour Diesel. 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. Average height will be 60-70cm indoor but some phenotypes can extend up to 80cms+ if grown outdoors in optimal conditions. 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. Outdoors, Ultra Lemon Haze can be planted from early March to the beginning of July but the flowering period will never be shorter than 60 days.
