Death Star Feminised Seeds: The Deep Purple Knockout
Buy Death Star seeds in Australia and unleash the power of the dark side. This infamous Indica-dominant hybrid is the crushing result of crossing the resin-heavy Sensi Star with the legendary funk of Sour Diesel. Death Star is a heavy hitter—a strain that delivers true, lights-out relaxation along with a unique, fuel-and-lemon flavour profile. If you’re chasing high-potency, deep purple flowers, and jars that weigh a ton, this is the genetic weapon you need in your arsenal.
Quick Stats
Indica-leaning 75/25, 22–26% THC, 9–10 weeks indoors; AU harvest late April/early May; yields ~550–600 g/m²; aroma = skunky fuel with a citrus back end. Matty’s note: “If you’re chasing that deep, almost black-purple colour in the final weeks, this is the one. Just drop the temp.”
The Legend
Death Star is a modern classic that rose from the clone-only scene in Ohio, USA. It’s an impeccable blend of two powerhouse genetics: the heavy, couch-locking resin bomb Sensi Star and the legendary, highly euphoric Sour Diesel. This pairing gives Death Star the best of both worlds: the Indica structure and heavy, lights-out vibe from Sensi Star, and the pungent, expansive skunk from the Diesel. It truly is a fusion of classic quality and modern potency.
Matty’s Note: “The name isn’t a joke. This strain is built to put you on your back. Keep the chill room handy.”
Flavour & Aroma
- On the grind: Immediate, abrasive, pungent skunk and kerosene.
- In the room: Overpowering dirty diesel—run that carbon filter or your neighbours will know.
- On the palate: Heavy jet fuel up front, smoothed out by sharp lemon and sweet earth on the finish.
Matty’s Take: “She smells like you spilled diesel on a lemon tree. It’s glorious, but you need a sealed environment.”
Effects & What to Expect
- First wave → The first hit smacks behind the eyes — like someone hit pause on your thoughts. The mental rush of the Diesel hits first.
- Then it settles → A warm, heavy wave drops from the head, spreading through the body and leading to whole-body melt.
- Final vibe → Knockout-level chill—you will be locked to the couch, ready for sleep or absolute zoning. This is heavy, full-body coverage.
- Day vs. night → Strictly night use. Avoid operating anything heavier than the TV remote.
Matty’s Anecdote: “I tried to watch a whole movie once. Woke up two hours later with the credits rolling and a drool stain on the cushion. Classic Death Star move.”
How I Grow It (Matty’s Way)
Grow Difficulty: Intermediate. Requires canopy control due to Sativa-like stretch and careful nutrient timing to prevent burn.
Structure: Medium height, very bushy, with aggressive lateral branching and thick, heavy colas.
Timing & Yield: 9–10 weeks indoors; ~550–600 g/m². Outdoors in AU, harvest late April/early May.
- Colour Activation: Drop nights to 15–18°C in the final two weeks (after stretch) to trigger purple.
- Training: SCROG recommended; one light supercrop if tops outrun the net (Weeks 2–3 flower).
Matty’s Note: “She’s no diva, just give her a bit of structure and she’ll repay you with bricks of bud. Drop your night temps to 15–18°C for colour—but only once she’s finished her stretch. Do it too early, and she’ll sulk.”
Matty’s Focused pH Notes (For Maximum Colour & Yield):
“To push those deep colours in the final weeks, the plant relies on efficient nutrient transfer, especially Phosphorus and Potassium. Stabilizing your pH is critical, as is dropping the night temperature. Stable pH allows for maximum colour expression.
- Soil/Coco: pH 6.3–6.6 (edge toward 6.3 in the final 3 weeks).
- Hydro/DWC: pH 5.9–6.2 (a touch higher than most indicas to suit the Diesel side).
Matty’s Advanced Notes (For the Nerds)
Death Star is a machine when dialed in. Hitting these tight ranges will maximize both yield and the signature colour profile:
- Key Terpenes: Caryophyllene (Spice/Fuel), Limonene (Citrus), Myrcene (Sedation/Earth).
- EC Target: Start flower at 1.6–1.8 EC, peak at 2.0 EC by mid-flower, then drop for the flush.
- Environmental Targets:
- VPD: Veg 1.0–1.2 kPa, Flower 1.2–1.5 kPa during the stretch phase.
- Late Flower Climate: Day 22–24°C, Night 15–18°C for colour. RH 40–45%.
- Lighting Target (PPFD): 1000–1200 µmol·m⁻²·s⁻¹ with CO₂ supplementation is the sweet spot for peak production.
- Training: SCROG is mandatory. Execute one light supercrop if tops outrun the net (Weeks 2–3 flower).
- Air Management: Under-canopy clip fans on 24/7 from Week 5; target 0.3–0.5 m/s leaf flutter.
- Pests: Watch for broad mites in dense canopies; weekly IPM spray until Week 2 flower.
- RED FLAG (Burn): The Diesel genetics can lead to Nitrogen toxicity quickly. Monitor tip colour and cap EC if needed.
- RED FLAG (Colour): Don’t drop night temps until Week 6+, or you risk slowing growth before the buds are ready to ripen.
Matty’s Note: “If your leaves aren’t gently wiggling, your buds are whinging.”
Grow Log: Inside the Tent 📅
| Phase/Week | Key Action/Status | Matty’s Tip |
|---|---|---|
| Seedling Week 1–2 | Root zone establishing; slow vertical, thickening stems. | “Keep it dry-ish early. Overwater now and she sulks for the whole run.” |
| Veg Week 3 | Topped above the 4th node. EC is 1.0. Ready to LST and flip next week. | Control the canopy early or she’ll stretch past the Scrog net in flower. Aim for VPD 1.1 kPa for vigorous stem growth. |
| Flower Week 3 | Stretch phase finished (approx. 100% gain). Canopy filled the Scrog. EC bumped to 1.6. | Ramp the EC up slowly towards 2.0. She’s hungry for PK now. Maintain pH at 6.0. |
| Flower Week 6–8 | Buds stacking massively; intense fuel and lemon smell. EC peaked at 2.0. | This is the temperature drop window. Ease night-time temps down to 18°C to initiate the purple colour mutation. Keep RH low (45%). |
| Flower Week 9 | Deepening purple colour across the leaves and buds. Trichomes mostly cloudy. EC dropped to 0.8 for flush. | If you want the heaviest end-of-day vibe, wait for 20% amber before flush. Maintain 18°C nights for maximum pigment development. |
| Harvest | Flush complete, chop after 10 days. Curing will lock in the deep colour. | Don’t rush the dry—the density means you need low, slow temps to avoid that hay smell. Trim heavy to expose the best buds. |
Matty’s Grow Story: The Deep Freeze Fade
I was once running a batch of Death Star, chasing that near-black purple that makes the flowers look toxic (in a good way, of course). I had the EC perfect (2.0) and the pH locked at 6.0, but the colour was only a faint lavender. The problem was my night temperature was still running at 21°C. I knew the Anthocyanins (the pigment that causes purple) only really express when the plant is stressed by cold. I dialled the AC down to hit a low of 16°C at lights-off for the last two weeks. The results were unreal: the fan leaves faded to crimson, and the buds turned a deep, royal purple with contrasting white trichomes. It looked like something from another planet. That small temperature drop was the difference between a great yield and a jaw-dropping one.
Mythbusting (🚫)
Myth: “Because it’s a Diesel cross, it’s racy and anxiety-inducing.”
Truth (Matty): The Sensi Star influence crushes the sativa jitters, resulting in heavy relaxation, not panic.
Myth: “You must use special nutrients to make it purple.”
Truth (Matty): It’s genetic; the color unlocks with a cool late-flower phase, not special nutrients.
Myth: “It’s a low-yield Indica.”
Truth (Matty): The Sour Diesel stretch means this plant is a monster, and if you Scrog her, she’ll yield with the best of them.
Who It’s For? (🎯)
Perfect If You:
- Want a heavy nightcap vibe and deep, full-body calm.
- Love pungent, fuel-heavy flavours and aromas.
- Are an intermediate grower who wants to chase maximum yield and colour expression.
Maybe Not For You If You:
- Need to be active or creative after consuming.
- Dislike strong, skunky aromas (she is LOUD).
- Are a first-time grower still learning to manage canopy and EC.
🏆 Final Verdict
Matty’s Final Word: “Death Star is the definition of heavy, classic potency. She combines the best traits of Sensi Star and Sour Diesel into one crushing, colourful weapon. If you want the deepest purple you can get, dial in that night temperature and get ready for a lights-out couch-lock vibe that owns your couch.”
