Deimos Auto

Deimos Auto Cannabis Seeds by Buddha Seeds

Deimos Auto is a feminised autoflowering cannabis seed strain descended from Northern Lights, stabilised over 7 generations of selective inbreeding by Buddha Seeds. She stays compact at 70–80cm, flowers automatically regardless of light schedule, and produces dense, resinous buds on every branch. Ten seeds per pack — enough to fill a small tent or run a proper outdoor patch without reordering mid-season.

Why Deimos Auto Stands Out

Northern Lights is one of the most decorated indica-dominant strains in cannabis history — and Deimos Auto packs that lineage into a plant you can grow on a windowsill. Buddha Seeds spent 7 generations inbreeding and selecting to lock the autoflowering trait in tight. The result is a strain that doesn't need a light-cycle change to flip into flower. She just goes, typically finishing in 7–9 weeks from seed.

What makes her genuinely useful is the combination of compact size and heavy yield. At 70–80cm, Deimos Auto fits comfortably under a 300W LED in an 80x80cm tent, but she branches out aggressively. You get massive nugs on the main cola and solid secondary buds on every side shoot. Indoor growers report yields around 500 grams per square metre under decent lighting. Outdoors, expect up to 125 grams per plant on the larger specimens — respectable numbers for a plant this short.

The aroma is sweet and herbal, nothing overpowering but distinctly Northern Lights in character. The smoke itself is thick, piquant, and luscious — the kind that coats the back of your throat and lingers. Effects lean mellow and relaxed, with enough potency to remind you where the genetics came from. She's not going to knock you sideways, but she'll settle you into the sofa properly.

Deimos Auto Grow Profile — What to Expect

This is a genuinely forgiving strain to grow, which is why we'd recommend Deimos Auto as one of the best autoflowers for first-time growers. The autoflowering trait means no messing about with 12/12 light schedules — she'll start flowering on her own roughly 3 weeks after germination, regardless of how many hours of light she gets. Run her under 18/6 or 20/4 indoors and she'll be happy.

One thing to watch: because she's compact and bushy, airflow through the canopy matters. Those dense side branches can trap moisture if your tent isn't ventilated properly, and that's how you get mould issues late in flower. A small oscillating fan pointed at the canopy does the job. If you're growing 2–4 plants in a tent, make sure you've got extraction running too.

Outdoors, Deimos Auto does well in most European climates as long as she gets a reasonable amount of direct sunlight. The short stature and fast finish mean you can plant her in May and harvest before the autumn rains set in — handy if you're in northern Europe where September weather gets unpredictable.

Deimos Auto Compared to Photoperiod Northern Lights

If you're weighing Deimos Auto against a regular photoperiod Northern Lights, here's the honest trade-off. Photoperiod Northern Lights plants grow taller, yield more per plant, and give you control over veg time — you decide when she flowers by switching to 12/12. That extra control means bigger plants and potentially higher potency, because you can veg for 6–8 weeks before flipping.

Deimos Auto sacrifices some of that ceiling in exchange for speed and simplicity. She's done in 7–9 weeks total, doesn't need a separate veg and flower light schedule, and stays under 80cm. For growers with limited space, limited experience, or limited patience, that's a genuine advantage. You also get the option to run multiple harvests per outdoor season, since she doesn't depend on autumn light changes to finish.

Neither is objectively better — it depends on your setup. If you've got an 80x80 tent and want results fast, Deimos Auto is the smarter pick. If you've got a dedicated flower room and don't mind the extra weeks, a photoperiod Northern Lights will reward the patience.

How to Germinate and Grow Deimos Auto Seeds

1. Soak your Deimos Auto seeds in a glass of room-temperature water for 12–24 hours until they sink. Seeds that float after 24 hours usually need a gentle tap to break surface tension — if they still float, they may not be viable.
2. Transfer the soaked seeds to damp paper towels on a plate. Fold the towels over, cover with a second plate to keep moisture in, and leave somewhere warm (20–25°C). Check daily. Taproots typically emerge within 24–72 hours.
3. Once the taproot is 1–2cm long, plant it root-down in a small pot of quality soil mix or coco coir, about 1cm deep. Water lightly — the soil should be moist, not soaked.
4. Place under 18–20 hours of light from day one. Deimos Auto doesn't need a dark period to flower, so more light means more energy for growth. A 300W LED is plenty for 2–4 plants in an 80x80 tent.
5. Avoid transplanting if possible. Autoflowers have a fixed life cycle, and transplant shock costs you growing days you can't get back. Start in your final pot — 7–11 litres is the sweet spot for Deimos Auto.
6. Feed lightly during the first 2–3 weeks (seedling stage), then increase nutrients as she enters pre-flower. She's a hungry plant once those side branches start filling out, but don't overdo nitrogen in flower — it'll slow bud development.
7. Harvest when 70–80% of trichomes have turned milky white. A cheap jeweller's loupe or USB microscope makes this easy to check. Waiting for a few amber trichomes will push the effect toward a heavier, more sedative finish.
