Kush Mass

Kush Mass Auto Cannabis Seeds by Garden of Green

Kush Mass Auto is an autoflowering feminised cannabis seed from Garden of Green that pairs Critical Mass with Pure Afghan genetics for heavy yields and a deeply relaxing indica-dominant effect. With 17–20% THC and a seed-to-harvest time of just 9–10 weeks indoors, this strain delivers serious weight without serious effort. If you want a Kush that practically grows itself and still fills your jars, this is the one we'd point you towards.

Kush Mass Auto Genetics and Lineage

Kush Mass Auto descends from Critical Mass and Pure Afghan — two strains that need no introduction if you've spent any time around indica-leaning genetics. Critical Mass brings the sheer volume: fat, dense colas that can snap branches if you're not careful with support. Pure Afghan delivers the old-school Kush backbone — earthy, resinous, and built for hash production. Garden of Green then folded in autoflowering genetics, which means no photoperiod fussing. The plant shifts into flower on its own clock, typically around week 3–4 from sprout.

The result sits roughly balanced between sativa and indica influences, though the effect leans firmly indica. You get a plant that stays compact enough for indoor tents but still pushes out the kind of yields you'd expect from a photoperiod strain. That's the Critical Mass influence doing its thing.

Growing Kush Mass Auto Seeds: What to Expect

Kush Mass Auto is one of the most forgiving autoflowers we've come across, and we've seen a lot pass through our catalogue since 1999. It doesn't demand precise feeding schedules or advanced training techniques. Give it decent light, keep the pH in range, and don't overwater — that's genuinely most of the job.

Indoors: Expect harvest 9–10 weeks after germination. Yields land between 450–550g/m² under proper lighting. An 18/6 light cycle from start to finish works well. The plants stay stocky, rarely stretching past 80–100cm, which makes them a solid fit for smaller tents or low-ceiling spaces.

Outdoors: This strain prefers warm, Mediterranean-style climates. Harvest falls around late September to early October in the Northern Hemisphere, and outdoor yields can reach up to 700g/m² in optimal conditions. That's a serious number for an autoflower — most don't come close.

Kush Mass Auto Aroma, Flavour, and Terpene Profile

Crack open a cured jar of Kush Mass Auto and the first thing that hits you is earth — deep, damp soil, like turning over compost in autumn. Behind that sits a sour, almost fermented edge that's unmistakably Afghan. The complexity builds from there: spicy and woody undertones layer underneath, with a citrus note that brightens everything up. On the exhale, there's a subtle sweetness and a clean pine finish that lingers on the palate.

This isn't a one-note strain. The terpene profile reads like a proper Kush — myrcene-heavy for that earthy base, with caryophyllene adding spice and limonene contributing the citrus lift. If you've ever smoked old-school Afghan hash and wished it came in flower form, this gets you most of the way there.

Kush Mass Auto Effects and THC Content

At 17–20% THC, Kush Mass Auto sits in the upper range for autoflowering strains. The effect is a powerful body stone — the kind that starts in the shoulders, works its way down, and firmly plants you on the sofa. It's an evening strain, full stop. Don't plan on being productive after a session with this one.

According to a review published in Molecules, cannabinoids and terpenes may work together through what researchers describe as an entourage effect, with terpenes potentially modulating how THC interacts with cannabinoid receptors (Inglet et al., PMC7409346). Kush Mass Auto's rich terpene profile — earthy myrcene, peppery caryophyllene, bright limonene — likely contributes to the deeply physical character of its effects.

Standard dosing research suggests that 5–10mg of THC represents a typical single dose, with 5mg often preferred for less experienced users. With flower testing at up to 20% THC, even a small amount of Kush Mass Auto goes a long way. Start conservatively if you're not used to strong indicas.

One honest note: this strain can leave you properly couch-locked. If you're after something functional or daytime-friendly, look at a sativa-dominant auto instead. Kush Mass Auto does one thing — deep relaxation — and it does it extremely well.

Why Kush Mass Auto Deserves a Spot in Your Grow

The autoflower market is crowded, and most strains make you choose: speed or yield, potency or ease of growing. Kush Mass Auto doesn't force that compromise. You get photoperiod-level yields (450–550g/m² indoors, up to 700g/m² outdoors), proper THC content at 17–20%, and a total lifecycle of just 9–10 weeks. For context, a lot of photoperiod indicas need 8–9 weeks of flowering alone, plus the entire vegetative phase on top.

The ease of growing is genuine, not marketing fluff. We've seen first-time growers pull respectable harvests from this strain with nothing more than a decent LED, some coco coir, and basic liquid nutrients. The Afghan genetics make it naturally resistant to common issues — it handles slight overfeeding better than most autos and doesn't throw a tantrum if temperatures drop a few degrees overnight.

Where Kush Mass Auto really earns its keep is in the final product. The buds cure into dense, resinous nuggets that look and smoke like something from a much more demanding plant. The complex terpene profile — that earthy-sour-pine-citrus combination — sets it apart from the generic "auto weed" that a lot of budget strains produce. This genuinely smells and tastes like proper Kush.

How to Grow Kush Mass Auto Seeds

1. Germination: Soak seeds in a glass of room-temperature water for 12–24 hours until they sink, then transfer to damp paper towels in a warm, dark spot. Taproots should appear within 24–72 hours.
2. Planting: Place the germinated seed taproot-down into its final container — autoflowers don't transplant well, so start in the pot you intend to finish in. An 11–15 litre pot works well for this strain.
3. Vegetative phase: Run lights at 18/6 from day one. Keep humidity around 60–70% for the first two weeks, then gradually reduce. Light feeding with a grow-phase nutrient from week 2.
4. Flowering: The plant will begin flowering automatically around week 3–4. Switch to bloom nutrients when you see the first pistils. Maintain 18/6 lighting throughout — autoflowers don't need a 12/12 flip.
5. Support and airflow: As buds fatten from week 6 onwards, add bamboo stakes or a trellis net. The Critical Mass genetics produce heavy colas that can snap branches. Good airflow around the canopy prevents mould in those dense bud sites.
6. Harvest: Trichomes should be mostly milky with some amber by weeks 9–10. Flush with plain water for the final 5–7 days if growing in soil or coco. Dry in a dark room at 18–20°C and 55–60% humidity for 7–10 days, then cure in glass jars for at least 2 weeks.
