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. 

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.

Forgot when I germinated and didn’t record the vegging stage. But it turned out quite well. After 90 days, it was harvested in November 2024 Under 2 lights. Actual power consumption (~200w)

Plant 1: Vigorous plant in Veg, but when switched to flower, strange things happened, the buds are really weird and did not eat as much as an average plant, and the production is low. Therpenes are really good, and the smell is particular, really nice. Nice resin, it is very sticky. The only thing i dont like about this plant is the phenotype. Plant 2: The smell is similar to the original Lemon, has deep citrous notes. I like the psychoactivity, its a nice day smoke, and a tasty one. Overall a very good plant, i love the therpene profile (citrous/fruity), it is so refreshing when you smell the citrous flavour. The plant turned purple since beginning of flowering, what makes it beautiful.

Very easy to grow, did under 12-12 in flowering even tho it’s an auto as the breeder recommended, nice sized light buds not very dense, smelled very VERY lemony and tasted as it smelled with a sour inhale, not too overpowering of a high definitely more of a head high long lasting effect quite a relaxing one

Harvested at day 77 from seed. She grew easily. No muss. No fuss. She smells of lemon and has an intense psychedelic high. It is somewhat energetic. It has a pretty good body buzz to it, as well.

This is beautiful, a lovely smell, out of this world lemon,the smoke is very potent, it will make some paranoid,i say this to inexperienced tokers, this is top shelf weed,I cant fault it, but you need to know its VERY strong.I really like it , at present there are three autos on the top of my list - BDM,CB, and ULH -This was everything i hoped it would be, and more.

Wow this is the most lemony strain I ever grew! Despite being grown outside, and quite late in the game, she pulled out with a bit over one ounce which I consider solid for an untrained outdoor auto. Growing was a breeze, and the final smoke is absolutely tremendous (a family member who hates the smell of pot in general, was quite taken by the smell of ultra lemon haze which speaks volumes:)) I'm definitely going to grow more of this strain, and I recommend you try it as well.
