Super Lemon Haze Rbx3 is the Ethos Genetics take on one of the most famous lemon sativas, reworked with the house Lilac Diesel line. She is strong and vigorous, with large, spongy flowers and thin, sparse leaves that make trimming easy, and she delivers flavors of sweet lemons, spices and berries.
This is an uplifting, social cultivar with a classic sativa effect. She flowers in 60 to 70 days, yields high and thrives indoors and outdoors, making her a versatile choice for growers who love haze character without a marathon bloom.
For anyone searching for the Super Lemon Haze strain in Ethos seeds form, this third reversed backcross is the version to grow, with TAC listed at 25-30%.
Super Lemon Haze Rbx3 Lineage: SLH Meets Lilac Diesel
The pedigree is SLH x Lilac Diesel #22 x [SLH x (SLH x Lemon OG Haze)]. The Super Lemon Haze used here is a 2009 cut. Lilac Diesel #22, a selected keeper from one of the signature Ethos lines, adds vigor and resin, while repeated crosses back to SLH reinforce the lemon-haze core.
Rbx stands for reversed backcross, and the 3 points to a later round of that process. Each backcross toward Super Lemon Haze helps lock in the citrus terps and sativa structure, while the reversal keeps the seeds feminized.
The Lemon OG Haze in the background adds another layer of lemon and a touch of OG density, which helps explain the satisfying weight of her flowers.
Aroma, Flavor and Effect
The aroma is sweet lemons first, bright and candied rather than sour. Warm spices weave through the citrus, and a berry note softens the edges. Ethos lists the terpene families as berry and lemon-lime.
On the palate she tastes like lemon drops with a hint of spice, and the berry comes through on the exhale. It is a clean, refreshing smoke that holds its flavor well after a good cure.
The effect is uplifting and social, a classic sativa experience. Expect a happy, energetic mood that suits daytime activities, creative work and time with friends.
Growing Super Lemon Haze Rbx3 Indoors and Outdoors
She is rated for intermediate and pro growers. Strong and vigorous, she shows good lateral and vertical branching, medium-to-tall height and medium internodes. Expect some stretch after the flip, so plan training accordingly.
Indoors, topping during veg and a SCROG net in early flower keep her height manageable and spread the large, spongy colas across the light. Her thin, sparse leaves make defoliation and trimming quick.
Outdoors and in greenhouses she thrives as well. Her 60 to 70 day flowering time is short for a haze-dominant plant, which gives outdoor growers a better shot at a clean finish before the weather turns.
Expect a high yield of large, citrus-scented flowers that are easy to trim.
