Credit where it belongs, right up front: Purpz is Humboldt Seed Company’s work, and it is a purple strain that actually smells like something. The Purpz strain crosses Garlic Budder with a GMO x CF-50 male to stack savory garlic funk and raw gas on top of deep purple, resin-heavy flower — savory purple weed, not the sugary kind. This clone guide covers the full picture: genetics, what the terps actually deliver, and how to grow the cut from rooted clone to jar. To look for Purpz clones, visit the I Want Clones shop.
Key Takeaways
- Purpz is an indica-dominant cross of Garlic Budder x (GMO x CF-50) bred by Humboldt Seed Company — real breeder credit, not mystery lineage.
- Purpz has a myrcene and caryophyllene-led profile of garlic, chem, and fuel over dark fruit.
- It flowers in 8–9 weeks, yields high, and finishes outdoors from late September to early October — a legitimate dual-environment plant.
- Grow difficulty is intermediate: the GMO blood brings vigor and stretch that reward training and punish neglect.
Purpz Genetics
Purpz is a deliberate piece of breeding, and the parents each pull real weight. The Garlic Budder mother contributes the savory, funky garlic edge and the dense, colorful flower set — she is the reason this plant goes deep purple with resin to match. The male side is a GMO x CF-50 cross, and the GMO blood is unmistakable in the finished product: that raw chem-and-fuel character GMO is famous for runs straight through Purpz’s profile. The CF-50 influence tightens up structure and speed, keeping the plant manageable and the flowering window honest.
Humboldt Seed Company built this cross. That matters because purple strains have a long history of trading flavor for color — bag appeal genetics that smoke like nothing. Purpz was bred against that trend: the color is there, but the garlic-gas profile is the point. Lineage is only worth what the actual plant in your tent can prove. For Humboldt Seed Company’s other purple-gas cut, see the Gazzurple strain and clone guide.
Aroma, Flavor and Terpene Profile
The reported profile on this cut leans myrcene and caryophyllene, and the nose tells you immediately that this is not dessert weed. Up front you get savory garlic funk — the Garlic Budder signature — riding over a chem-fuel undercurrent from the GMO side. Underneath that sits a darker, almost stewed-fruit sweetness that reads more like reduction than candy. It is a complex, adult profile: loud, layered, and distinct from the sugary Z-family purples.
Flavor follows the nose. Expect savory funk on the inhale, gas through the middle, and a dark fruit finish that builds as the jar cures. The caryophyllene gives the smoke a peppery weight. Fair warning for the tent: this terp profile does not hide. Mid-flower Purpz will test your carbon filter the way any GMO descendant does, so treat odor control as required equipment rather than an option.

Growing Purpz: What You Need To Know
Purpz grows like a plant with GMO in its veins: vigorous, hungry for light, and quick to fill space once it settles in. Expect moderate-to-strong stretch in the first two weeks of flower, dense flower set on strong lateral branches, and the deep purple expression coming on as flowers mature — you do not need cold-shock tricks to get the color; the genetics handle it.
Indoors, give it a proper veg of two to three weeks after transplant and plan your canopy around the stretch. Outdoors it finishes late September to early October, which keeps it viable in most northern climates before the fall rains get serious. Environment-wise, run standard targets: 40–60 percent RH depending on stage, and keep VPD dialed — our VPD guide for clones has the numbers by growth phase. Start every run right: when the box lands, work through our what to do when clones arrive checklist before the clone ever sees full light.
Training for Maximum Yield
Purpz’s vigor is an asset if you direct it and a liability if you don’t. Untrained, it wants to run a dominant main cola with lanky side branches — fine for a closet plant, wasteful in a real tent. Top it once above node three or four early in veg, and it responds by throwing strong, even mains that take low-stress training beautifully. Tie the mains out flat, keep the canopy level through the stretch, and you convert that GMO vigor into bud sites instead of height.
For growers running multiple Purpz clones, a ScrOG net pays for itself: the stretch fills the screen fast and the high yield potential of this cut shows up best on a flat, evenly lit canopy. Support matters late — purple, resin-dense flowers at weeks seven and eight get heavy, and branches that looked sturdy in veg will lean. Stake or trellis by day 21 of flower. The full technique walkthrough is in our topping and LST guide.
Feeding and Nutrition
This is a high-yield, fast-building plant, and it eats accordingly. Purpz takes medium-to-heavy feeding once established: work rooted clones up gently from EC 0.8, hit EC 1.6–2.0 through mid-veg, and let it peak around EC 2.0–2.2 in the bulk weeks of flower. The GMO side gives it a real appetite for nitrogen in veg and phosphorus-potassium through flower stack — underfed Purpz yields like an average plant, and that is leaving weight on the table.
Two cautions. First, taper into full-strength feed rather than jumping — fresh transplants that get slammed with hot nutrients stall, and our clone feeding guide maps the ramp week by week. Second, keep cal-mag steady under LED, because dense purple flower pulls calcium hard and deficiencies show up as rot-prone soft spots late. pH targets are standard: 5.8–6.2 in coco and hydro, 6.2–6.8 in soil.
Common Problems
Three issues account for most Purpz complaints. One: stretch surprise. Growers who flip a full tent of vegged Purpz without accounting for two weeks of aggressive stretch end up managing a canopy against their light. Flip earlier than feels natural. Two: late-flower humidity. The flower density that makes this cut yield high also makes it vulnerable if RH creeps past 55 percent in weeks seven through nine — airflow under the canopy and moderate defoliation are cheap insurance.
Three: feeding whiplash. Because Purpz eats hard in peak flower, some growers keep that intensity too long and lock the plant out just as it should be finishing. Watch tips, back off EC in the final two weeks, and if you overshoot, flush and recover using our lockout and flushing guide. None of these are dealbreakers — they are the normal tax on an intermediate plant with high output.
Why Buy Purpz as a Clone Instead of Seeds
Humboldt Seed Company sells Purpz seeds. But a seed pack is a lottery of phenotypes — some leaning garlic, some leaning fruit, some purpling hard, some barely at all. Finding the keeper means popping a pack, sexing, running them to flower, and culling — months of work and multiple tent cycles before you know what you have.
A clone of a selected cut skips the entire hunt. The ACC cut is a known quantity: known terp expression, known stretch, known finishing window. You are growing the plant you read about in this guide, not a genetic possibility of it. To look for Purpz clones, visit the I Want Clones shop. For other indica-dominant cuts, see the indica-dominant clone library.
Who Is Purpz For?
Purpz fits the grower who has a run or two behind them and wants a plant that rewards competence: real yield and a finished product with genuine bag appeal and a profile to match. It suits anyone whose market or personal taste runs savory — GMO fans, garlic-strain loyalists, and people bored of candy terps will feel at home immediately.
It is also a smart pick for outdoor growers in temperate climates, since the late-September finish beats the worst of the autumn weather. Skip it if you need a hands-off beginner plant — the stretch and appetite want attention. First-timers who want something more forgiving should start in our week-by-week clone timeline and work up to it.
Harvesting, Drying, and Curing
Purpz finishes in eight to nine weeks indoors, about 60 days for most runs of this cut. Start checking trichomes at day 50: cloudy with first amber for an earlier finish; pushing amber past 15 to 20 percent gives a later finish. Outdoors, plan for late September to early October and watch the weather window — dense purple flower and cold rain are a bad combination.
Dry it slow and cold: 60°F, 60 percent RH, 10 to 14 days. The garlic-gas profile is volatile, and a hot fast dry strips exactly the terps you grew this plant for. Cure in jars or bags at 58–62 percent RH with daily burps for two weeks. Give it three weeks minimum before you judge it — the savory depth and dark fruit finish develop noticeably between week one and week four. The purple color holds through a proper cure and deepens in the jar.
FAQ
Who bred the Purpz strain?
Purpz is a Humboldt Seed Company cross of Garlic Budder and a GMO x CF-50 male. The clone is the ACC cut of that cross.
Does Purpz actually turn purple without cold temperatures?
Yes. The purple expression is genetic, inherited primarily through the Garlic Budder side, and shows up under normal flowering conditions as the flowers mature. Cooler nights late in flower can deepen the color, but you do not need to stress the plant to get it.
