The Best Ace Seeds Genetics: Strain Guide

Top Ace Seeds Cannabis Strain Buyers' Guide

Discover 25 of the best cannabis strains from Ace Seeds—breeders specializing in landrace genetics. This buyers’ guide features popular feminized and regular seeds in the Ace Seeds catalog. Every strain listed below is available for domestic U.S. shipping.


Malawi

Malawi by Ace Seeds

Malawi is Ace Seeds’ flagship pure landrace sativa strain, bred from the legendary Old Malawi Killer and selected third-generation Malawis. Packing 24–27% THC, this Central African heirloom delivers searing psychedelic intensity that embarrasses many modern hybrids. Its lanky frame flaunts medium internodes and exhales a piercing mix of oily wood, lemon rind and subtle sweet-carrot undertones.

Indoors, flip to bloom after roughly two weeks of veg or when rooted clones establish, and blast the canopy with high-intensity light to tame its stretch. Flowers finish in 10–13 weeks inside or late October/early November outdoors, handing out bumper harvests while resisting heat, molds, and most pests. Malawi thrives in SOG for towering spears but also fills SCROG nets when topped thanks to vigorous lateral growth.

Glistening foxtails stack densely, each swollen calyx sheathed in oversized trichomes. The smoke oozes diesel-oil over hardwood and citrus, while select phenos add a mandarin-sweet twist driven by a myrcene-limonene core. Expect four hours of kaleidoscopic visuals, chest-thumping euphoria and a finish that only veteran psychonauts withstand.

Golden Tiger

Golden Tiger by Ace Seeds

Golden Tiger fuses Old Malawi Killer with elite Koh Chang and Hmong Thai lines, crafting a 100% sativa F3 hybrid renowned for raw power and exotic pedigree. Testing at 25–30% THC, this high-THC strain unleashes jungle vigor alongside refined Thai citrus-floral aromatics. Huge resin heads crown tight budlets that sparkle like sunlit dew on bamboo leaves.

Provide strong light, ample root space and an 11/13 bloom schedule to temper the 11–14-week flowering stretch. Plants branch wildly yet reward SOG with colossal tops or SCROG with wall-to-wall colas, finishing outdoors around November in warm zones up to 43° N/S. Feed lightly on nitrogen but boost PK mid-flower to drive weight without foxtailing. Despite the delicate look, mold rarely bothers these flowers, making yields both heavy and healthy.

Buds burst with ripe mandarin, lemon zest, and spicy incense over a sticky Malawi resin core. Myrcene and limonene dominate the terp stack, with nerolidol adding depth for vapor-friendly flavor and monstrous entourage effects. The high is a tidal wave: immediate rocket-fuel clarity, then swirling, time-stretching psychedelia that can leave new users speechless and veterans euphoric for hours.

Congo

Congo by Ace Seeds

This F1 mash-up pairs rare Bangi Congo and Congo #3 with a touch of Pakistan Chitral Kush, creating a 70/30 sativa that radiates upbeat African energy. At 15% THC and 9–10-week bloom times, it punches well above its modest numbers, gifting growers a vigorous, mid-height frame with wild-strawberry perfume. Magenta fades and hardy genetics make it a photogenic, collector-grade choice.

Congo shrugs off humidity, cold snaps, and common pests—perfect for growers up to 45° lat. or anyone battling fickle weather. Indoors, she adapts smoothly to moderate feeding and standard 12/12 schedules, forming a hefty main cola plus eager laterals that fill screens fast. Outdoors, her early-October finish beats autumn rains while still packing on trichomes. Slight purple flashes appear late in bloom thanks to the Chitral influence.

Finished flowers form long, resin-frosted spears that sparkle silver against purple bracts, releasing petals-and-grape aromatics layered with blackberry jam. Expect a clean, motivational sativa buzz—creative, social, and caffeine-like without jitters—thanks to a terp profile heavy on sweet floral esters. It’s a “daytrip” cultivar that keeps minds open and feet moving.

African Gas

African Gas by Ace Seeds

By crossing Bangi Haze F8 with Neville’s legendary A5 Haze, Ace engineered a 60/40 sativa beast famous for its explosive, flammable-gas nose. THC peaks around 22% but feels stronger, as Northern Lights heritage injects a narcotic gut-punch beneath the Haze ascent. Phenotype diversity means every pack hides a potential unicorn, while all phenos produce massive colas worthy of its menacing name.

Indoors, consider an 11/13 cycle to tame her 12-week bloom and curb early stretch, while outdoors she sizes up into a spear-laden Christmas tree that’s ready by late October or early November in most climates. Plants guzzle nutrients, demand strong light and reward both SOG and SCROG with football-sized tops that may need staking. Heat tolerance, mold resistance and sheer yield make her a commercial standout.

Colas harden into chunky, resin-glazed horns that leave sticky fingerprints on everything. Roughly 30% of plants deliver pure explosive gas with solvent, damp peat and even decaying-flower back notes, while others mix citrus, mango and earthy African haze. Inhale cautiously—the gas pheno locks limbs, melts time and drops even seasoned smokers into deep, paralyzing body sedation.

Panama

Panama by Ace Seeds

Three elite Panamanian sativas unite in this stabilized showpiece, hailed by Ace as the finest American pure-sativa hybrid of the last two decades. THC averages 21%, and tall, branching plants routinely flaunt pink or ruby pistils reminiscent of old-school Panama Red sativas from the seventies. Lemon-vanilla incense dominates the scent, with strawberry flavors in certain phenos.

Indoor growers enjoy 9–12-week flexibility; Panama handles high light, varied training, and even SOG when flipped early. Outdoors she stretches gracefully, thriving from tropical settings to 45° lat., finishing late October with surprising botrytis resistance. Feed generously—especially PK mid-bloom—and watch colas swell like flamingos in the sunset. Provide ample root space and watch the yields climb sky-high.

Buds are large, dense and dripping with trichomes, often showing pastel reds deep into cure. Terpinolene leads the terp chart (nearly 50%), giving blossoms a sharp citrus edge, while pinene and limonene brighten the bouquet. The green pheno delivers electric, soaring clarity; red expressions slump into heavier, dreamy realms. Either way, buds gleam with sticky resin that extracts like a dream.

Purple Haze x Malawi

Purple Haze x Malawi by Ace Seeds

Ace married vintage Purple Haze #23 with Killer Malawi pollen to craft a towering, pure sativa that merges 1970s mystique with 21st-century muscle. Expect 18–23% THC, towering sativa stature, and yields big enough to tax your drying room after 13–15 weeks of bloom. Blackberry liqueur, red wine, and incense terpenes swirl from every node.

Indoors, start pruning early and flip no later than day 15 (11/13 lighting recommended) to keep spires manageable; SCROG nets capture the lateral bounty. Outdoors she demands tropical to warm coastal regions, finishing in November up to 43° lat., but rewards patience with festival-sized harvests that ward off mold. Moderate feeding of bloom nutrients, especially light in nitrogen, preserves her lanky grace and vibrant terp development.

Long, foxtailed buds shimmer with violet hues, exhaling fermented berry jam, citrus zest, and oily wood. Myrcene and pinene dominate, backed by linalool for a spicy floral exhale and marathon potency. The effect is clean yet forceful: vivid visuals, racing thoughts, and an inspiring creative spark that stretches on for ages before landing you softly with a satisfied grin.

Killer A5 Haze

Killer A5 Haze by Ace Seeds

A5 Haze (NL #5/HazeA) meets Killer Malawi to forge an 80/20 sativa hammer notorious for 30% THC ceilings and volcanic yields. Despite the sativa-leaning heritage, internodes remain moderate, making her surprisingly manageable indoors or out while yielding phenomenally. This poly-hybrid channels old-school Dutch church incense laced with meaty funk and woody rot.

She’s ravenous—push strong lighting and heavy nutrients from start to finish, and employ SCROG or SOG to sculpt multiple cola beasters over 9–12 weeks. Outdoors, climates with hot summers and dry, warm autumns unlock her full girth, wrapping by early November. Resistance to powdery mildew, heat, and mites keeps maintenance low for such a heavy yielding monster.

Colas are long, dense and drenched in sticky resin, releasing aromatic waves of incense, liver pâté and decomposing petals. Beta-myrcene and limonene dominate the terp stack, making every toke thick and musky. Effects are brutally psychedelic—visual warping, uncontrollable laughter, then a deep opiate-like stone that can floor the uninitiated.

Thai Chi

Thai Chi by Ace Seeds

Chiang Mai Thai meets Kali China F4 in this balanced 70/30 sativa gem that captures wild Thai sativa vigor yet flowers in a forgiving 10–11 weeks. Vibrant red-hued phenos add bag appeal, while THC hovers around 16% for an approachable, lucid experience. Sour grape and bitter-lemon aromas mingle with incense and chocolate for truly exotic terps up there with today’s best strains.

Indoors, veg under strong light but expect irregular branching. Early growth shows broad leaves before exploding upward, so top or train aggressively—SCROG nets tame wayward limbs and boost returns. Outdoors she powers up to 45° lat., laughing off rain and cold while finishing by late October. Moderate nutrients keep her happy. Give plants space in open soil and yields rocket from moderate to chunky.

Harvest reveals silvery spears with blush red or near-black pistils, exuding earthy lime, mint, and blackcurrant over a cured-wood backbone. Terpinolene dominates alongside ample myrcene, pinene and caryophyllene, granting a crystal-clear, cheerful headspace with gentle body tingles—great for contemplative creativity. Zero paranoia, just balanced, enlightened euphoria.

Kalidonia

Kalidonia by Ace Seeds

Kalidonia crosses a short-flowering New Caledonia II with Kali China, crafting a compact, columnar 60/40 indica that finishes in just eight weeks. It’s tailor-made for balconies, tents, and new growers who crave top-shelf resinous buds without marathon flower times. Cool nights trigger blue-red fades that light up Instagram feeds.

Inside, a simple 18/6 veg and 12/12 bloom schedule is all it needs. These short plants seldom exceed three feet but stack bud sites like oversized corn cobs. Outdoors, expect harvest by mid-October even in temperate zones, with excellent pest resistance and forgiving nutrient demands. Average yields belie dense buds that dry down with little shrinkage.

Menthol-herbal freshness melts into tangy citrus, creamy sweets, and a Kali China backdrop of mango hash, leather, and incense. Potency sits in the 17% THC range, delivering an uplifting yet balanced high suitable for any time of day. Depending on phenotype, effects span clear-headed creativity, gentle body relaxation, or a dreamy indica haze perfect for unwinding.

Pakistani Chitral Kush

Pakistani Chitral Kush by Ace Seeds

Pakistani Chitral Kush (PCK) is a pure Himalayan indica famed for its kaleidoscopic reds and purples and bubble-hash resin. Bred in Spain since the ’90s, this purple strain remains a mold-proof champion that ripens by late September as far north as 50° N—ideal for short summers. Its narrow genetic lineage gives it consistent, classic hash-plant charm. Coffee, caramel, and berry-chewing-gum aromas make trimming almost edible.

Indoor cultivators appreciate the broad indica frame, short nodes, and mild feed requirements that simplify perpetual runs. Outside, she shrugs off rain, cold, and botrytis, thriving in anything from Mediterranean heat to northern drizzle. Moderate nutrients and minimal training keep her on cruise control. Stake once, water well, and watch the show of color as nights cool.

Mature buds glimmer like sugared blackberries, smelling of caramel latte, citrus peel, cherry candy and berry chewing gum courtesy of dominant geraniol and humulene. Smoke is smooth, sweet and slightly spicy, evoking fresh hashish from the Hindu Kush valleys. The high is gentle, soothing and pleasantly introspective—ideal for evening wind-downs or blending into rosin.

Himalayan Snow

Himalayan Snow by Ace Seeds

Himalayan Snow blends Annapurna and Kathmandu wild sativas with a dash of old Kali Mist, forging a 90% sativa that oozes snow-white resin and fruity charas charm. Two phenotypes emerge: lanky Nepalese spears or chunkier Kali-influenced flowers, both topping out around 15% THC but feeling brighter than the numbers suggest. Tall stature and sparkling trichomes echo Himalayan vistas after a storm.

Indoors, allot 10–12 weeks of bloom and plenty of vertical space, or move outdoors for end-October/early-November harvests where cool nights intensify terpenes. It holds up against rain, wind, cold and mold, thriving from Mediterranean terraces to mountain valleys. SCROG training maximizes side-branch production, and low-to-moderate nutrition prevents hermie stress.

Finished flowers sparkle white over lime-green calyxes, emitting strawberry yogurt, banana cream and incense-hash notes with a hazy bittersweet finish. Her leaves even frost up with trichomes, proving perfect for charas-style hand-rubs. Myrcene, pinene and caryophyllene dominate the terp profile for head-clearing flavor. The high is clean, energizing and expansive without any couchlock.

Auto Malawi x NL

Auto Malawi x NL by Ace Seeds

Ace’s first autoflower strain marries Old Killer Malawi to auto Northern Lights, bringing 50/50 balance, modern vigor, and photoperiod-free convenience. Plants start flowering around week 4 and finish in 9–10 weeks total, producing huge main colas and side branches that rival many photo strains. Three phenos appear: fast indica, heavy green sativa/indica, and rare long-flower sativa showcasing purple Malawi flair.

Autoflowering means the clock starts at sprout—plants initiate bloom at week four or five regardless of light schedule, finishing 9–10 weeks later indoors or outdoors up to 55° latitude. Start in 7 L pots inside or 15–20 L pots outside, keep nutrients moderate, and stake the heaviest branches late flower. Resistance to cold, heat, mildew and pests makes it a set-and-forget autoflower.

Buds flash pinks and purples in Malawi-leaning plants or remain lime-green in the bigger yielders, all coated in sticky resin. Aromas swing from strawberry yogurt and pineapple-peach juice to rich woody spice, depending on phenotype. The effect unfolds in three acts—clear, talkative lift; dreamy introspection; finally a warm, narcotic blanket that ushers in restful sleep.

Bangi Haze

Bangi Haze by Ace Seeds

Bangi Haze, an F8 Congolese/Nepalese classic, is one of Ace Seeds’ oldest and most stabilized sativa strains. Fast 9–10-week flowering and 15–20% THC make it a staple for outdoor growers needing speed without sacrificing quality. Even indoors, its manageable profile allows for optimized yields. The scent of sweet flowers, lemon, musk and anisette announces its presence well before harvest.

Bred in rainy Galicia, Spain, Bangi Haze resists cold, fog and botrytis, finishing as early as the first week of October outdoors or thriving under lights inside. Medium height, good branching and moderate node spacing let light penetrate deep, while only medium nutrient levels are required. Whether run untrained or tucked into SCROG nets, yields stay consistently above average.

Rock-hard, frosty buds pump out classic pinene-myrcene terps wrapped in musky sweetness. The high is clean, electric, and seemingly bottomless, building altitude with every hit yet never fraying nerves—perfect for productive mornings or long creative sessions. Hash makers adore her resin quantity and old-school African zest.

Nepal Jam

Nepal Jam by Ace Seeds

Nepal Jam marries a hearty Nepalese highland mother with a vintage 1985 Jamaican male, distilling classic Asian vigor into a squat, beginner-friendly plant. Although 60% sativa, Ace Seeds managed to tame the stretch, keeping average height under 4 ft without sacrificing its mountain resilience. A unique, low-variance genotype and rapid onset of flowers make this line a staple for breeders seeking fast, cold-proof sativa character.

Indoors it races to harvest in just 8–9 weeks, thriving under moderate feed and strong light while shrugging off cool night temps that would stun lesser sativas. Outside it handles wet fog or icy snaps with ease, finishing around late September and averaging 400 grams per plant even at higher latitudes. Tight internodes and a high flower-to-leaf ratio simplify pruning, SCROG, or SOG.

The buds cure into chunky, hash-laden spears dripping with myrcene-rich resin that oozes caramel, honey, and floral incense. Flavor mirrors the aroma—creamy wood and sweet nectar on the inhale, faint spice on the exhale. Effects launch with a warm, soaring clarity that keeps spirits buoyant for two to three hours before gently setting you back on solid ground.

Kashmir

Kashmir by Ace Seeds

Kashmir is Ace’s rare, unhybridized P3 indica strain straight from the Himalayan valleys, preserved after three generations of careful in-house selection. Gigantic jurassic leaves, deep purple pigments and an earthy musk announce its old-world hash-plant pedigree. With THC and CBD chemotypes co-existing, this heirloom offers breeders untouched gene-pool diversity seldom seen outside the region.

Indoors it stays stocky and columnar, finishing in 9 weeks, while outdoor gardeners in temperate zones can chop during the first days of October. She handles both searing heat and alpine chills, resists botrytis, and chugs happily on moderate-high nutrients without fuss. Branch count is low, so a single-cola SOG or tight rows in raised beds keep yields consistent and canopy management simple.

Compact, rock-hard buds sparkle under a sheen of amber resin that darkens the sugar leaves to wine-red and near-black in cool nights. Cured flowers push a dense, elegant smoke of bright lemon over layers of floral hash, leather, wet peat and a cheeky barnyard funk, courtesy of myrcene, limonene and caryophyllene. Effects start with a clear, motivational headspace before melting into sublime body calm. It’s like premium temple-ball sans couchlock.

Super Malawi Haze

Super Malawi Haze by Ace Seeds

Super Malawi Haze fuses Nevil’s legendary early-’90s Haze mom with Ace’s feared Malawi Killer, forging a 90% sativa powerhouse that screams vintage Dutch breeding supercharged by African ferocity. Colossal vigor, towering frame and monstrous cola length set it apart from ordinary Haze strains. Three phenotypes—Nevil’s-leaning, Malawi-dominant and rare near-pure Haze—promise treasure hunts for both production growers and adventurous collectors.

Start flowering after a two-week veg, run an 11⁄13 schedule, and be prepared for 85–95-day bloom sessions indoors or November harvests outdoors in warm latitudes. She drinks heavy but repays with arms-thick, resin-caked spears that easily pass 600 g/m² under intense light or several pounds per sun-grown tree. Trellising or SCROG keeps sprawling branches in check, while her naturally high resistance to botrytis guards those dense colas from autumn rot.

The cured buds glimmer silver-green, interlaced with fiery orange hairs and drenched in greasy trichomes. Aromatically, expect sweet floral incense, tropical wood and fermented Malawi funk over a terpene backbone of pinene, myrcene and limonene. The smoke is a rocket—electric, kaleidoscopic and deeply creative for hours, yet clean enough to leave you sharp and athletic.

Creeper Gouge

Creeper Gouge (Creeper Tiger) by Ace Seeds

Creeper Gouge—also listed as Creeper Tiger—marries the brain-bending Golden Tiger sativa to ErdPurt’s hardy Afghani, landing in a 50/50 hybrid that hits like a stealth freight train. Its medium-compact Malawi/Afghan frame hides surprisingly heavy equatorial colas that reveal its Thai heritage once bloom kicks in. Only type-I plants are produced from these regular seeds, so the cannabinoid profile stays THC-rich with negligible CBD across the population.

Indoors the cultivar wraps up in a brisk nine weeks, happy under standard 12/12 and tolerant of both low humidity and cool night swings. Outside it thrives up to 43° N, finishing by mid-October with impressive mold resistance and an appetite for moderate-high feeding. Secondary branching responds well to topping, making it equally suitable for SCROG nets or open-air guerilla plots.

Resin stacks thick and sticky on lime-green flowers that carry a faint ErdPurt musk beneath zesty lemon, green-tea and spice notes. Dominant terpinolene and pinene deliver a bright, herbaceous inhale before the flavor settles into woody incense and mild hash. The effect lives up to its name—initially giddy and soaring, then layering dreamy psychedelia and deep body sedation in creeping waves that can last all evening.

Panama x PCK splices the frosty, red-purple Pakistani Chitral Kush elite 2002 with the 10th-generation Panama Goddess, crafting a color-splashed 50/50 that smells like a candy factory in the jungle. Compact Pakistani stature meets Panama’s tropical branching for a manageable yet vigorous bush. Ace’s breeders delivered an F1 hybrid exotic that shines with rainbow pigments and breeder-grade stability.

She slots neatly into tents, finishing in 9–10 weeks or around early October outside up to 47° latitude. Central-cola dominance makes her fantastic for SOG, but she also explodes sideways when trained, rewarding SCROG artists with multilayered canopies. Heat, cold, drought and mold are shrugged off, and solid yields come effortlessly on a moderate nutrient diet, letting even beginners score chunky harvests.

Buds glow fuchsia and ultraviolet under the sugar frost, exuding strawberry-blackberry bubblegum wrapped in Panamanian lemon-incense. High myrcene, nerolidol and bisabolol give the smoke a syrupy mouth-feel and brilliant aromatherapy potential. Effects settle into a contemplative, meditative calm that quiets the mind without stealing clarity.

Honduras

Honduras by Ace Seeds

Honduras captures the essence of lowland Colombian giants in a pure 100% Central American landrace cultivar rescued in 2015. Tall, flexible branches, massive internodes and jungle vigor recall the golden-age exports of the ’70s, while its upbeat personality leans closer to vintage Mexican sativas. With unique genetics and moderate variability, it offers breeders a blank slate for energetic, high-yield hybrids.

Expect 13–14 weeks indoors and mid-November harvests outdoors, where it holds up in monsoon rains and resists botrytis thanks to its airy spear-shaped buds. Give her strong light, lower nitrogen after stretch and plenty of root space for best results. Yields can be staggering both in single-cola SOG or wide SCROG screens. Soft NPK during veg then heavy PK after week three keeps the towering spears stacking properly.

Finished flowers are lime-green and feathery, yet caked in glistening resin with minimal leaf for easy processing. The bouquet combines floral musk, geranium zest, citrus peel and sandalwood riding on terpinolene-myrcene dominance. Each hit delivers clean, jitter-free energy that keeps conversations bright and limbs motivated—no ceiling and zero crash.

Auto Zamaldelica squeezes the psychedelic Zamal x Malawi/Thai lineage into a fast, non-photodependent format by crossing it with Auto Malawi Northern Lights. The 75% sativa autoflower stays compact yet delivers genuine tropic power in just 12–13 weeks from seed to harvest. Three distinct terpene groups, from candy fruit to lemon-Haze to woody African, make every pack of feminized seeds an exploration.

Sow directly into at least 7 L pots indoors or 15–20 L outdoors to maximize size. Moderate veg feed followed by heavier bloom nutes keeps growth explosive. Heat, cold, pests, and rot barely make a dent, and its 0–55° latitude range means nearly every grower can squeeze in multiple cycles per season. Expect rewarding yields of tight golf-balls. Bonus: it can share a veg tent with mothers, finishing under 18/6 light.

Buds are small, hard and glimmer with sugar, emitting either mango-peach candy, sharp lemon fizz or dark Malawi wood depending on phenotype. Terpinolene and myrcene dominate the profile, backed by ocimene and limonene for layers of sweetness and zest. 75% percent of plants unleash a heady psychedelic high that’s overwhelming to novices, while the rest offer a calmer, narcotic cuddle without losing clarity.

Malawi x Panama by Ace Seeds

Malawi x Panama unites Ace’s fearsome Old Malawi Killer with their latest-generation Panama elites, resulting in a 100% sativa F1 that drips resin like no tomorrow. African potency meets Central American lemon-incense in a vigorous yet surprisingly tame stretch pattern. With THC routinely over 25%, this cross sits among Ace’s most potent offerings, reserved for connoisseurs who crave intensity.

Indoors she prefers SCROG, switching after a brief veg and finishing in 11–12 weeks. Outdoors she comes down end October to early November up to 43° N. Heat tolerance is excellent, and branches hold dense spears without needing excessive staking if airflow is maintained. Keep nitrogen low after early veg, then feed high through flower to see truly outrageous yields.

Chunky, greasy buds shimmer with rings of trichomes, releasing oily spice and wood from the Malawi side wrapped in lemony incense from Panama. Terpene tests show a near-even split of αpinene and terpinolene bolstered by caryophyllene and humulene—perfect for heady concentrates.

Orient Express

Orient Express couples the elusive, resin-laden Vietnamese Black sativa with a quick, squat Chinese Yunnan indica to deliver Asian charm in a small-garden package. Semi-stabilized through three generations, it balances 60% sativa lift with 40% indica manageability. Growers have loved this line since Ace’s early days for its rainforest aroma and reliable performance.

A suitable indoor strain, it caps at around 3½ ft and flowers in 8–10 weeks, rewarding a warm start followed by cooler late bloom for optimal density. Branchy structure takes nicely to topping or SOG, and nutrient demand stays high until week six of flower—don’t be shy with food. Outdoor cultivators in hot or mild climates harvest by early October, with average resistance to common molds and pests.

Finished buds are chunky, olive-green and dusted in sandy trichomes that exude deep earthy rainforest funk with floral undertones. Myrcene, pinene and nerolidol create a damp forest palate that lingers pleasantly on the tongue. Effects are warm, friendly and paranoia-free, making it a superb shareable smoke for social sessions.

Panama x Bangi Haze

Panama x Bangi Haze by Ace Seeds

A new strain from Ace, Panama x Bangi Haze blends the 10th-generation Panama Goddess with 8th-generation Bangi Haze, forging one of Ace’s finest F1 sativa hybrids of recent years. Bushy yet manageable stature meets explosive cola production, thanks to the synergy of Central American and African genetics. THC levels of 18–21% and a kaleidoscopic terpene mix are lifted by a 3% CBG content for rounded clarity.

Flowering completes in 10–11 weeks indoors or by mid-October outside, and plants relish strong light plus generous feeding throughout the cycle. She takes topping, SCROG or SOG equally well, filling nets with fragrant spears while resisting cold, heat and botrytis alike. Average-high yields reward connoisseur sativa to diligent growers who maintain airflow around the dense blossoms.

Colas are resin-lacquered and radiate complex aromas—musky florals, lemon zest, sweet carrot candy, anise and thick incense. Terpinolene heads the chart at roughly 40%, backed by pinene, myrcene and a hefty dose of nerolidol for a head-clearing inhale. The high is psychedelic, euphoric and dreamlike, pushing creativity to the edge while lasting deep into the evening.

CBD #1

CBD #1 by Ace Seeds

CBD #1 is Ace Seeds’ first fully stabilized high-CBD cultivar, averaging 15–18% CBD with a near-negligible 0.6% THC. Crossing Cannatonic S1 with CBD-rich ErdPurt, breeders packed medicinal punch into a 60/40 sativa-indica frame. It retains rich Afghani resin traits, turning sugar leaves into snowy sticks of extraction gold. A twenty-plus-to-one CBD:THC ratio means crystal-clear relief without psychoactive turbulence.

Plants are robust and columnar, completing indoors in a snappy 7–8 weeks or outdoors by the end of September even at 45° N. They accept both SOG and SCROG; prune once for extra branching, then feed moderate-high levels throughout, respecting dry-down cycles to avoid overwatering. Average-high yields of mid-sized, extremely sticky buds make it a commercial-scale candidate for full-spectrum CBD extracts.

A tidal wave of sweet ripe tangerine, tropical fruit, floral gummies and earthy pine greets the nose long before the jar opens. Dominant myrcene combines with pinene, limonene and caryophyllene for an aromatic bouquet that rivals any high-THC strain in intensity. The effect is gently uplifting, tension-melting and anxiety-dampening, perfect for daytime relief of pain or stress without impairment.

China Yunnan

China Yunnan by Ace Seeds

China Yunnan is a nearly pure indica landrace from the mountains bordering Myanmar, Laos and Vietnam, serving as a rare connective thread between Asian broadleaf and narrowleaf lines. Ace’s third-generation work maintains robust vigor while preserving intriguing sativa hints in leaf shape and early effect. Few modern breeders have tapped this untouched genome, making these affordable seeds a treasure for collectors and hybrid projects.

She finishes in 8–9 weeks indoors or by late September/early October outside, happiest in warm, dry climates but surprisingly adaptable elsewhere. Columnar plants yield monster central colas under short veg indoors, while outdoor bushes form ball-shaped silhouettes when given more space. Feed generously, keep temps around 77°F early then drop to 68°F late flower to maximize density and resin.

Buds are chunky, resinous and can lean creamy sweet-and-sour, dark hash-incense or woody-floral depending on phenotype. High α-pinene, myrcene and limonene marry with caryophyllene and guaiol, producing a layered aroma that deepens with a cool cure. The onset is cheerful and visually bright before melting into warm, relaxing body vibes that quiet both muscles and mind.

About Ace Seeds

Ace Seeds Logo

Ace Seeds, founded in 2005, is a seed bank centered on conserving unique and pure landrace cannabis strains worldwide, countering the reduction of genetic diversity within the cannabis community. This collective of breeders based in Spain has a mission to counteract the dwindling biodiversity by offering exclusive, stable, and unique hybrids developed mostly from landrace genetics. Their distinctive offerings capture the interest of connoisseur growers in pursuit of unparalleled cannabis experiences.

According to Ace Seeds, the shrinkage of genetic diversity in cannabis results from factors ranging from disappearing ancestral cultures and natural habitats to laws prohibiting research and genetic contamination. The collective combats this issue employing its vast library of sativa strains, trying to conserve the highest possible genetic quality.

Ace Seeds boasts experience with an array of sativa genetics from across the globe, hailing from countries as diverse as Panama, Malawi, and Thailand, just to name a few. Additionally, they offer landrace indicas sourced from nations such as Afghanistan, Pakistan, and China.

Landraces form the basis for Ace Seeds’ classic strains. They embark on preservation initiatives with authentic and superior landraces, replicating all varieties for future generations. Subsequently, they refine and enhance these unique strains, boosting their best traits via parental plant selection. Eventually, they integrate the best traits from varied landraces, resulting in hybrids that exhibit greater adaptability and power. Many of these hybrids are further stabilized through multigenerational selection within expansive and healthy populations.

Ace Seeds strives to improve the deficiency in genetic variety and curtail degradation that cannabis strains have faced for decades. They primarily do so by providing genetics that stand out for their freshness and difference as cherry-picked from their extensive catalog of sativa strains recognized across the planet. The dedication towards preserving and studying cannabis by the team at Ace Seeds exemplifies their commitment, contributing to protecting biodiversity while unlocking the untapped potential held by cannabis strains globally.
