Purple weed that actually smells like gas is rare. That single fact is the entire pitch for the Gazzurple strain, sometimes marketed as Purple Gas — a Humboldt Seed Company creation that delivers grape-colored flower soaked in diesel, berry, and cream, on a flowering clock fast enough for perpetual rooms. If you have been burned by pretty purple strains that smoke like hay, this clone is the correction. Gazzurple clones are available here, freshly rooted, HLVd screened, and shipping now. This guide walks through the genetics, the disputed indica-sativa question, and how to grow it for both color and weight.

Key Takeaways

• Gazzurple is a Humboldt Seed Company strain built from a Gazzurple Bx2 backcross crossed with Poddy Mouth x Macaroon.
• The cut in our library tests 21–25% THC; breeder seed runs have been reported near 30%.
• Flowering is fast — roughly 7 to 9 weeks, with the breeder listing about 50 days on the seed line.
• Expect sativa-style vigor and stretch in veg, then tight, indica-structured flower and an indica-leaning finished effect.
• It is reported as surprisingly mold resistant, and the dense grape-cluster colas trim fast.
• Cool night temperatures in the last two weeks deepen the signature purple color.

Gazzurple Genetics

Gazzurple is Humboldt Seed Company’s work, and the lineage is confirmed across the breeder’s own page, Leafly, and SeedFinder: a Gazzurple Bx2 backcross paired with a Poddy Mouth x Macaroon male.

The backcross is the important part. Backcrossing a selected mother locks in her signature traits — in this case the purple-gas character, the grape color and the diesel nose — so the seed line reproduces what made the original cut special instead of scattering it. The Poddy Mouth x Macaroon side folds in dessert sweetness and hybrid vigor, which is where the cream in the aroma and the aggressive veg growth come from.

One wrinkle worth being honest about: HSC lists the seed line with a sativa-leaning ratio, while Leafly and most cut holders describe it as indica dominant. Having watched this plant grow, both are sort of right. It stretches and builds like a sativa, then throws tight, indica-structured flower and lands with an indica-style calm. We shelve it with our indicas because that is how the finished product behaves — but plan your veg space for the sativa half of its personality.

If purple gas is your lane, HSC’s other heavyweight in that vein has its own writeup in our Purpz strain and clone guide — the two make an interesting side-by-side.

Aroma, Flavor and Terpene Profile

The breeder describes it best: classic gas, berries, and cream. The nose opens with diesel and a sweet grape tartness, then a creamy dessert layer underneath, with skunky, kushy edges when you break a bud.

The smoke follows the nose — grape-forward and sweet on the inhale, earthy diesel on the exhale. It is a profile with more personality than the average purple cultivar, which typically trades flavor for color. Gazzurple refuses that trade, and that is the whole reason the strain has a following.

No terpene percentages here — we do not quote certificate-of-analysis numbers we have not verified ourselves. But the profile in the room is unmistakable: purple fruit riding on fuel, loud enough that you will not need a lab report to find it.

Gazzurple Effects: What To Expect

Gazzurple starts with an energetic, euphoric lift, then rolls into relaxed, happy body comfort as it settles. Leafly’s user reports log energetic, uplifted, and focused alongside relaxed — which tracks perfectly with the hybrid genetics underneath the purple.

Call it a late-afternoon strain: engaged enough for music, food, or good conversation, calm enough that you will not fight it at wind-down time. Smokers who find pure indicas too sleepy tend to like the lifted front end, while indica people get the landing they came for. At 21–25% THC in our cut, it is potent without being punishing. No medical promises — just a well-rounded high with more range than the color suggests.

Growing Gazzurple: What You Need To Know

Cuts that finish fast and still color up like this are the exception, and that is Gazzurple’s whole pitch. Humboldt Seed Company lists roughly 50 days of flowering on the seed line; realistically, plan 7 to 9 weeks on the clone and use the extra time to build density and color.

Yield runs above average to high, and the flowers form dense, grape-cluster colas that the breeder accurately describes as looking like grapes left out in the snow. The structure trims fast, which your harvest crew — even if that crew is just you at a kitchen table — will genuinely appreciate.

Two traits make it friendlier than most purples for outdoor and greenhouse growers: it is reported as surprisingly mold resistant, and the fast finish means outdoor plants come down late September to early October, ahead of the worst fall weather. Indoors, it slots beautifully into perpetual rotations, where the quick turnaround compounds into an extra harvest or two per year.

The label says intermediate difficulty, and here is what that actually means: nothing about Gazzurple is fragile, but managing the vegetative stretch and the late-flower temperature drop is what separates a decent run from a showpiece. If you are new to running clones on a schedule, our cannabis clone timeline week by week lays out exactly what to expect from rooted cut to flip.

Training for Maximum Yield

This plant grows with sativa vigor before flipping, so the training plan starts early. Top early — once at the fourth or fifth node, again if your veg window allows — and expect real stretch after the flip. Trellis or stake before flowering, not during, because moderate support is what keeps those heavy grape clusters off the floor in weeks 6 through 8.

For growers choosing a canopy strategy, Gazzurple’s fast flower and dense cola structure make it a legitimate candidate for either camp: SOG rooms can run untopped clones tight and let the fast finish do the work, while SCROG growers can use the vigorous stretch to fill a net quickly. We break down that decision in ScrOG vs SOG for cannabis — with a cut this fast, either approach turns the speed into yield, and the wrong answer is only having no plan for the stretch at all.

Feeding and Nutrition

Feed to match the two-phase personality. In veg, Gazzurple’s vigor means a genuine appetite — steady nitrogen and enough cal-mag to support the fast frame-building, especially under LED.

After the flip, transition cleanly to bloom ratios and keep phosphorus and potassium steady through the bulking weeks. The colas stack quickly on this cut’s compressed schedule, so mid-flower underfeeding shows up faster than it would on a 10-week strain — watch the plant weekly, not monthly.

The finish is where discipline pays. Taper feed over the final two weeks while you drop night temperatures for color. A leaner finish plus the cold snap gives you the deep purple, a clean fade, and smoother smoke in one coordinated move. Do not chase a bigger yield with late nitrogen; on a fast finisher you will pay for it in flavor and never make it back in weight.

Common Problems

Unmanaged stretch is problem number one. Growers see “indica” on the shelf tag, veg it like a squat kush, and end up with a plant through the ceiling by week 3 of flower. Respect the sativa-style veg growth: top early, flip a little sooner than feels natural, and have support ready.

Second, color chasing gone wrong. The purple deepens with cooler nights late in flower — ease night temps down over the final two weeks. What you should not do is crash temperatures into the 50s hoping for more purple; you will slow ripening and stress the plant for marginal gains. Low 60s at night is the sweet spot.

Third — and this is a compliment — impatience. The breeder’s 50-day number tempts growers to chop at day 50 regardless of what the trichomes say. On the clone, the extra one to two weeks is where density, full color, and the cream note in the terps all arrive. Let her tell you when she is done.

Why Buy Gazzurple as a Clone Instead of Seeds

The seed line exists, and HSC does good work — but a seed run means variation. Some plants will lean toward the sativa expression, some purple hard, some barely at all, and the THC spread between phenos can be wide. The reported near-30% numbers come from standout seed plants, not the average one.

The clone removes the variance. Our cut is a selected, verified pheno testing a consistent 21–25%, with the fast finish, the mold resistance, and the color response already proven across runs. You also skip the germination-sexing-selection cycle entirely and go straight from rooted cut to veg — on a strain whose whole appeal is speed, starting with a rooted clone extends that advantage by a full month or more.

Gazzurple clones are available here at $98.88, freshly rooted and shipping now — no cut-to-order wait on this one — HLVd screened with monthly PCR testing, to all 50 states. Browse the rest of our indica strain clones if you are building out a purple-leaning menu.

Who Is Gazzurple For?

Growers who want fast turnaround without sacrificing bag appeal — which makes it a smart pick for perpetual rooms and commercial flips. The mold resistance and quick trim make it friendlier to outdoor and greenhouse growers than most purple strains. Smokers who find pure indicas too sleepy will like the lifted front end.

It is also a strong choice for a first purple strain, with one condition: you need to be able to manage the vegetative stretch. If your last grow got away from you vertically, practice your topping and trellis game before giving this one a run. Everything else about it is forgiving.

Harvesting, Drying, and Curing

Watch trichomes from day 50 onward and expect the real window between weeks 7 and 9. Outdoors, that means late September to early October. The grape clusters come down dense and — mercifully — trim fast, so harvest day on Gazzurple is shorter than its bag appeal would suggest.

Dry at 60°F/60%RH for 10 to 14 days. The dense clusters hold core moisture like any tight-flowered indica structure, so verify with the snap test before jarring. In the cure, the diesel edge softens and the berries-and-cream side steps forward — burp daily for two weeks, then weekly. Three weeks in glass is the minimum before this flower shows you what it actually is, and the purple keeps deepening in the jar as chlorophyll fades. Serve it in clear glass; it does half your marketing for you.

FAQ

Is Gazzurple an indica or a sativa?

It depends which end you measure. The breeder lists the seed line with a sativa lean, but it flowers with tight indica structure and the finished effect settles relaxed — which is why Leafly calls it indica dominant and why we shelve it as an indica.

How strong is the Gazzurple clone?

Our cut tests 21–25% THC. Humboldt Seed Company has reported seed plants approaching 30%, but 21–25% is the honest range for the clone we ship.

How fast does Gazzurple flower?

Fast. The breeder lists roughly 50 days; on the clone, plan 7 to 9 weeks and let trichomes, color, and density make the final call.

How do I get the deepest purple color from Gazzurple?

Ease night temperatures down into the low 60s Fahrenheit over the final two weeks of flower. The pigment deepens with the cool nights — no need for extreme cold, which slows ripening without adding much color.
