Grow facts
Grow facts come from the breeder first, then seed banks and strain databases. With 2 sources we show the range and the middle; with 3 or more, the range and the median, after leaving out values far from the rest. The breeder's own value is the anchor, unless it is far from every other source (outside their range and more than 20% from their median); then we show the full range and the median of all of them. A fact from a single source is marked "1 source", and a fact no source lists is left out. Yields are converted to one unit: indoor per square meter, outdoor per plant.
CTU writes every profile from these facts; we do not copy other sites' descriptions. Values that are a generic default in the source data are left out. Last checked Oct 21, 2026.

Spirit In The Sky is a balanced 50/50 hybrid bred by Exotic Genetix from Peyote Purple and Starfighter F2, delivering 16-18% THC with uplifting energetic effects ideal for growers seeking daytime reliability. The strain's bushy profile and dense colas make it excellent for both indoor and outdoor cultivation, responding exceptionally well to topping and SCROG-style training. Its crystal-coated resin coat and quick 8-week flower finish attract growers wanting both aesthetic bag appeal and efficient turnover. New growers appreciate its forgiving nature and predictable yields in moderate conditions.
Spirit In The Sky produces a fast-acting uplifting high that hits within minutes of consumption, launching into energetic euphoria and sustained motivation. The effect progresses from bright front-end clarity into a motivated, social buzz ideal for daytime use or active situations, without heavy sleepiness. Users report sustained energy lasting 3-4 hours with minimal crash, making it a reliable pick-me-up throughout the day. The balanced genetics mean onset remains quick while effects retain clarity rather than producing the body drag common in heavier indicas. Later harvests (moving toward amber trichomes) lean slightly more relaxing while maintaining the uplifted core character.
The jar aroma strikes immediately with earthy grape and sour lavender notes, a distinctive spicy-fruity profile that builds with exposure. On the inhale, the smoke carries warm grape and lavender sweetness balanced by peppery spice from caryophyllene, landing smoothly without harsh edges. The exhale reveals underlying citrus brightness from limonene, finishing with lingering earthy-grape and subtle herbal notes. Proper curing for 3-4 weeks locks in the complex spice-and-grape balance, preventing the aroma from flattening into generic earthy tones. The terpene profile develops more pronounced citrus pop in sealed jars, making this strain reward extended aging.
Spirit In The Sky thrives indoors under controlled humidity (40-50% target) with strong air circulation, and outdoors in warm, dry climates where the dense colas access full airflow. Indoors, topping in week 3 of veg encourages 4-6 main colas that yield 400-550 g/m² under 600W HPS or equivalent LED; outdoors, the strain reaches medium height with minimal stretch. SCROG training shows exceptional results given the strong training response, allowing growers to create even canopy layers and maximize light penetration through the dense interior colas. LST branches outward readily, reducing the need for aggressive techniques early on. Maintain moderate feeding (EC 1.0-1.3) and watch late-flower humidity discipline closely; while mold risk is naturally low due to the open canopy structure, dense interior colas demand consistent 40-50% RH in weeks 7-8 of flower to prevent bud rot. Expect flower finish around day 56, with outdoor harvest in October under normal photoperiod.
Because this strain's training response is strong and the canopy fills in quickly under topping pressure, delaying your first top until week 5 of veg costs you 10-15% of final yield by leaving uneven node height through flower-start training in week 3 instead to lock in a level canopy that translates to even light penetration and faster ripening across all colas.
New growers seeking reliable, forgiving strains thrive with Spirit In The Sky due to its beginner-friendly profile, moderate environmental tolerances, and responsive topping behavior that rewards early training attempts. Indoor growers using topping or SCROG benefit from the strain's strong training response and dense colas that yield 400+ g/m² in controlled rooms with proper humidity and airflow discipline. Outdoor growers in warm, dry climates (southwestern US, Mediterranean regions) see the strain's full potential with 500-700 g per plant and vibrant purple-black pigmentation under natural photoperiod. Growers focused on extract or hash production value the high resin coat on upper colas, which concentrates terpenes when properly harvested and cured cold.
Compared to Bubba Kush, Spirit In The Sky flowers 2 weeks faster (8 vs 10 weeks) and produces lighter, more energetic effects suited to daytime rather than evening use. Sherbert is similarly beginner-friendly but leans more toward dessert-sweet flavors rather than the earthy-grape spice profile, and typically runs 1-2% higher THC. Girl Scout Cookies shares the caryophyllene backbone and uplifting effects but requires more vigilant humidity management and stretches taller, demanding more aggressive veg training to maintain canopy evenness.
Spirit In The Sky contains 16-18% THC with 1-2% CBD, landing in the moderate-to-potent range suitable for both new and experienced users. This potency level delivers noticeable uplifting effects without overwhelming intensity, making it reliable for daytime or functional use.
Spirit In The Sky is a balanced 50/50 hybrid created by breeding Peyote Purple (indica-dominant) with Starfighter F2 (also indica-dominant), resulting in hybrid structure that leans slightly compact with bushy lateral growth. Despite the indica genetics, the uplifting effects come forward prominently from Starfighter's happy, euphoric heritage.
Spirit In The Sky flowers in 8 weeks (56 days), a relatively quick finish that makes it attractive for indoor growers planning multiple harvests annually. Outdoor plants under natural photoperiod finish in October in most northern hemisphere climates.
Yes, Spirit In The Sky is beginner-friendly with forgiving environmental tolerances and strong response to basic topping and LST techniques. New growers appreciate the predictable bushy structure, manageable height, and consistent yields of 400-550 g/m² indoors without requiring advanced defoliation or nutrient precision.
The dominant flavor is earthy grape with sour lavender and peppery spice undertones, creating a distinctive fruity-herbal profile with citrus brightness on the exhale. The aroma on jar opening is striking earthy-grape with lavender sweetness, developing more complex citrus notes after 3-4 weeks of cure.
