MAC Stomper
Also known as: M.A.C. Stomper
Breeder: Capulator
MAC Stomper is a resin-forward, indica-leaning hybrid bred by Capulator that marries the frosty cookie-fuel profile of M.A.C. with the grape-citrus punch of Grape Stomper. Sought after for dense trichome coverage and layered fruit-cookie aromatics, it has become a staple in craft indoor scenes and a proven parent in modern breeding programs. Hashmakers prize its heavy frost for solventless extraction, and consumers appreciate its balanced arc from mild cerebral euphoria into deep physical calm. SeedFinder tracks 67 direct descendants, underscoring its breeding value. MAC Stomper represents the pinnacle of Capulator's MAC breeding program. The strain gained rapid popularity in the craft market for its combination of exotic terpene expression (grape, citrus, vanilla, spice) with elite resin production that rivals dedicated hash plant genetics. Dominant terpenes are beta-caryophyllene, limonene, and myrcene. The high opens with a euphoric cerebral onset—a fast-hitting wave of positive mood elevation from the Chemdawg heritage in MAC—before settling into deep physical relaxation from the Grape Stomper's indica influence. It is widely regarded as one of the most visually striking modern cultivars, with buds displaying deep emerald green accented by purple-black outer leaves, bronze pistils, and a resplendent coating of milky trichomes.
Lineage & Genetics
Cross: MAC 1 x Grape Stomper
MAC (Miracle Alien Cookies) is Capulator's signature creation—Alien Cookies x (Colombian x Starfighter)—famous for its citrus-cookie fuel bouquet and extreme trichome density. Grape Stomper OG is a cross of Grape Stomper (Purple Elephant x Chemdog Sour Diesel) and Underdawg OG (Headband x Sour Diesel), contributing grape-forward terpenes, sour citrus brightness, and vigorous structure.
Lineage Dispute
SeedFinder and SeedsHereNow list the cross as 'M.A.C. x Grape Stomper OG' (Grape Stomper OG = Grape Stomper x Underdawg OG), while The Highest Critic and the consumer market commonly state 'MAC 1 x Grape Stomper.' Capulator's own SeedFinder entry does not specify whether the MAC parent is the MAC 1 cut specifically. AllBud lists the ratio as 70/30 indica-sativa; Capulator's SeedFinder description states 90/10 indica-sativa.
Terpene Profile
Caryophyllene — Sharp spice reinforcing fuel and diesel character
Limonene — Sharp citrus edge contrasting fuel undertones
Myrcene — Earthy, musky base grounding the fuel-forward profile
Pinene — Resinous pine adding solvent-like sharpness to fuel
Humulene — Hoppy earth reinforcing heavy, dank undertones
Linalool — Delicate floral contrast to heavy gas notes
Aroma: Opens with vanilla shortbread and powdered sugar sweetness from the MAC side, layered over tangy grape peel and orange zest. Beneath the candy top notes sits a warm, peppered, kush-like spice and deep earthy base that reviewers compare to old-school hash. Grinding releases a volatile burst of bright citrus and pine that settles into a spicy-sweet lingering nose. The Highest Critic noted the unmistakable MAC aroma with added hints of berries, lemon, and a musty earthiness.
Flavor: Initial draws are sweet-forward—vanilla-graham cracker, soft grape skin, and lemon cream coat the palate. Exhales shift to orange-lime zest and light pine before resolving into a warm, toasty, pepper-spice finish. As the session progresses, grape notes intensify into a grape-soda quality. Vaporization at lower temps (350–375 °F) accentuates limonene brightness; higher temps push the caryophyllene spice and caramelized sugar. In fresh-frozen rosin, hashmakers report a syrupy mid-palate and lingering bakery finish.
Effects & Experience
Onset: Arrives within minutes when inhaled, beginning as a mild cerebral lift with limonene-pinene brightness—mood elevated, internal monologue quiets.
Transitions from an uplifting, lightly euphoric head high into a grounded, tranquil body calm. Lower doses keep the experience functional and conversational; heavier consumption tips toward couch-lock and time dilation. The Highest Critic described it as a gentle head high that transforms into a stimulating cerebral buzz before settling into a mellow, relaxing body high.
Duration: 2–3 hours for most users, with peak effects at 20–30 minutes.
Commonly Reported Uses
Grower's Notes
MAC Stomper is an indica-dominant hybrid bred by Capulator, created by crossing his legendary MAC 1 (Miracle Alien Cookies) with Grape Stomper OG. The result is a resin-forward cultivar that inherits the dense, frosty bud structure and exotic terpene complexity from MAC while gaining the grape-forward aromatics and robust plant structure from Grape Stomper. THC typically ranges 22-28%.
Growth Structure and Training
In the vegetative phase, MAC Stomper exhibits moderate vigor with a well-branched hybrid structure. Plants develop medium-to-large frames with dense foliage that benefits from selective defoliation to improve light penetration and airflow to interior bud sites. Maintain an 18/6 light schedule at 70-80F and 55-65% relative humidity during veg. The strain is a moderate-to-heavy feeder—use a nitrogen-rich base nutrient at 1.2-1.8 EC during vegetation, increasing as the plant matures.
Growth Structure and Training
When flipped to 12/12, expect a moderate stretch of 1.5-2x over the first 2-3 weeks. This is an ideal time to install trellis netting if using SCROG, as the stretch fills the net naturally. Transition to bloom nutrients (elevated PK ratios) once stretch completes. MAC Stomper is known for exceptional resin production—trichome development begins early and intensifies through the entire flower cycle, making it an outstanding candidate for solventless extraction.
Flowering Time and Harvest
Flowering runs 8-9 weeks for most phenotypes. The MAC-dominant phenos tend to finish closer to 9 weeks with rounder, denser nugs and a vanilla-cookie nose. Grape Stomper-dominant phenos may finish a few days earlier with more elongated bud structure and pronounced grape/citrus aromatics. Both phenotypes produce hulking, dense buds covered in a thick layer of glistening trichomes.
Environment and Climate
Environmental control during flower is critical. Target 75-80F daytime / 65-70F nighttime temps with humidity dropping progressively from 50% at the start of flower to 40% by week 6. The dense bud structure is susceptible to botrytis if humidity spikes—defoliate heavily at the flip and again at week 3 to promote airflow through the canopy. Good HVAC with consistent negative pressure is recommended.
Bud Structure and Trichomes
The terpene profile develops late—the characteristic grape soda, lemon zest, and cookie dough notes really emerge in the final 10-14 days. A slow dry (10-14 days at 60F/60% RH in darkness) followed by a 3-4 week cure in sealed jars at 62% RH preserves these volatile monoterpenes. Rushing the dry will flatten the complex aromatic profile into generic hay notes.
Environment and Climate
Outdoors, MAC Stomper performs best in warm, dry climates with consistent sun. It is not well suited to humid coastal environments due to its mold-susceptible bud density. Harvest typically falls in early-to-mid October.
History & Origin
Capulator rose to prominence after stabilizing Miracle Alien Cookies (M.A.C.), one of the most sought-after cultivars of the modern era. MAC Stomper extends that lineage toward a more indica expression with Grape Stomper influence, targeting heavier resin production, denser structure, and a grape-citrus terpene overlay. The cultivar's rollout relied on selective distribution of regular (non-feminized) seeds rather than mass-market release, fostering scarcity and hype in craft circles. By the early 2020s its reputation was cemented among connoisseur communities, and its consistent trait transmission made it a go-to parent for third-party breeders.
