Sativa-dominant Ultra Lemon Haze is the result of crossbreeding Lemon Haze (a former overall Cannabis Cup winner) and Sour Diesel. The resulting hybrid was then further crossed with Auto#1, which contains excellent Ruderalis genetics. The Ruderalis genetics mean that this is a short-growing autoflowering variety.
When you light up Ultra Lemon Haze weed, you’ll immediately notice the clean, citrus fruit aroma and then you’ll taste lemons and grapefruits combined with some sour tones that come from the Diesel parent. Expect a cerebral, buzzy hit that will leave you feeling engaged and active.
This plant only grows to a maximum height of 80 centimetres, and often tops out at as little as 60 or 70 centimetres. The bright green leaves have slender serrated fingers and the dense buds have a longish, conical shape and orange hairs. In medical use, this weed can help with sleep and appetite problems.
As an autoflowering type, Ultra Lemon Haze grows well indoors in a controlled environment, although you may need to vary its feeding between the vegetative and the blossoming stages. Flowering time is around eight to nine weeks. Increasing the flowering time should lead to a more potent crop and yields are in the medium range.
Ultra Lemon Haze seeds grow successfully outdoors but like all strains the more warm sunshine it gets, the better it will do.
Smokers who enjoy an energetic high and a citrus fruit flavored smoke will definitely appreciate Ultra Lemon Haze. It can be on the difficult side to cultivate successfully, so it’s probably not for novice growers.
