Auto Anesthesia Cannabis Seeds by Pyramid Seeds
Auto Anesthesia is a feminised autoflowering cannabis seed from Pyramid Seeds that crosses Northern Lights with Black Domina to produce a compact, resinous plant in just 7 weeks from germination to harvest. At 40–100cm tall with yields up to 550g and 17% THC, this indica-dominant auto is one of the best autoflowering seeds for small grow spaces — short enough for a 60x60cm tent, sturdy enough that you won't need to stake the branches.
Pack Size
Auto Anesthesia comes in packs of 5 feminised seeds. Every seed is female — no males to cull, no wasted tent space.

Running Auto Anesthesia in a small tent? Pair it with a complete grow kit that includes lighting, ventilation, and a carbon filter — everything a 60x60cm setup needs to get from seed to harvest without cobbling parts together. A decent pH meter is also worth grabbing; autos don't give you recovery time if the root zone drifts.
Why Auto Anesthesia Seeds Deserve a Spot in Your Grow Room
Seven weeks from popping a seed to chopping a plant. Most photoperiod strains haven't even finished their stretch by then. Pyramid Seeds built Auto Anesthesia by crossing two heavyweight indica parents — Northern Lights and Black Domina — and the offspring inherited the best traits of both: compact structure, dark resinous buds, and a growth speed that makes perpetual harvesting realistic even in a single tent.
The growth structure is what separates Auto Anesthesia from the crowd. You get thick, dark green foliage on a frame that tops out between 40 and 100cm. The branches are stocky enough to hold up dense, lime-green coneheads without extra staking — and that matters, because once those buds fatten up and get dappled with trichomes, a weaker branch would fold. We've seen plenty of autos that claim big yields but need a scaffolding system to deliver. This one doesn't.
The honest limitation? At 17% THC, Auto Anesthesia isn't going to compete with 25%+ photoperiod monsters for raw potency. But that's actually a selling point for a lot of growers. You get a solid, usable flower without the kind of knockout strength that pins you to the sofa after one hit. If you want the heaviest hitter in the Pyramid Seeds catalogue, look at their photoperiod Anesthesia instead. If you want speed and reliability in a small space, Auto Anesthesia is the smarter pick.
Auto Anesthesia Flavour and Aroma Profile
The terpene profile on Auto Anesthesia runs from sweet to sour — a range you'd expect from Northern Lights genetics layered with Black Domina's darker, earthier undertones. Fresh plants smell herbal and slightly pungent during the final weeks of flower, and that sweetness sharpens into something more acidic once the buds cure. It's not a one-note strain. The flavour shifts depending on how long you cure: a week gives you something sweeter and greener; three to four weeks brings out the sour, almost citric edge underneath.
Competitors describe the terpene profile as herbal and pungent, which is fair, but undersells the complexity. There's a resinous, almost piney quality to the trichome layer that comes through when you break a bud open — sticky fingers guaranteed. If you've grown Northern Lights before, you'll recognise the base note. Black Domina adds depth.
Growing Auto Anesthesia Seeds — Tips From
Auto Anesthesia is one of the most forgiving autoflowers we've come across, and we've stocked a lot of them since 1999. The compact frame means you can fit 4 plants comfortably in a 60x60cm tent, or go wider in an 80x80 and give each plant room to bush out. Outdoors, the roughly 60-day cycle means you can run multiple rounds in a single season — start one batch in April, another in June, and you're harvesting twice before autumn.
- Germinate using the paper towel method or directly in a small pot of light, airy soil. Taproots usually appear within 24–72 hours.
- Transplant into your final container early — autos don't recover well from transplant shock, so move them before the third node if you're not starting in the final pot. An 11-litre fabric pot is a solid match for this strain's root structure.
- Run an 18/6 or 20/4 light schedule from start to finish. Auto Anesthesia doesn't need a light-cycle change to flower — it'll switch on its own around week 2–3.
- Keep feeding light through veg. This plant stays compact, so it doesn't need heavy nitrogen. Switch to a bloom feed once you see the first pistils.
- Watch humidity in the final two weeks. Those dense, lime-green coneheads pack tight, and mould loves a dense bud in stagnant air. Keep airflow moving and humidity below 50% RH during late flower.
- Harvest when roughly 70–80% of trichomes are milky with a few turning amber. At 17% THC, timing your harvest gives you more control over the final effect than almost any other variable.
Auto Anesthesia vs Photoperiod Anesthesia — Which One?
Pyramid Seeds offers both an autoflowering and a photoperiod version of Anesthesia. The genetics overlap, but the growing experience is different enough that it's worth comparing before you commit.
| Feature | Auto Anesthesia | Anesthesia (Photoperiod) |
|---|---|---|
| Seed to Harvest | 7 weeks | 8–9 weeks flowering + veg time |
| Height | 40–100cm | Taller, requires training |
| THC | 17% | Higher (typically 20%+) |
| Yield | Up to 550g | Higher potential with longer veg |
| Light Schedule | 18/6 or 20/4 throughout | Requires 12/12 flip to flower |
| Best For | Small tents, fast harvests, beginners | Experienced growers wanting max potency |
If you've got a small tent and want results in under two months, Auto Anesthesia is the obvious choice. If you've got height, time, and the patience to train a photoperiod plant, the original Anesthesia will reward you with stronger flower. Neither is better — they solve different problems.
What the Buds Look and Feel Like
Auto Anesthesia produces dense, conical buds with a lime-green base colour and dark green sugar leaves curling through the structure. The trichome coverage is heavy for an auto — you can see the frost building from about week 4, and by harvest the buds look like they've been rolled in sugar. Break one open and the inside is sticky, resinous, and compact. These aren't airy popcorn nugs; they've got weight to them.
The dark foliage is a Black Domina trait. Some phenotypes push purple hues in the final week if night temperatures drop below 15°C, though this is cosmetic rather than functional. Either way, it's a good-looking plant — the kind you'd photograph for your grow diary.
Frequently Asked Questions
How long does Auto Anesthesia take from seed to harvest?
Seven weeks from germination. Outdoors, expect roughly 60 days. This is one of the fastest autoflowers in the Pyramid Seeds lineup — most growers chop between day 49 and day 55 indoors.
What yield can I expect from Auto Anesthesia?
Up to 550g under optimal conditions. Realistically, indoor growers in a 60x60cm tent running 4 plants can expect solid returns without any advanced training techniques. Outdoor yields depend on sunlight hours and climate.
Is Auto Anesthesia good for beginners?
Yes. The compact structure, sturdy branches, and short lifecycle make it very forgiving. You don't need to manage light cycles, and the plant doesn't stretch enough to cause headroom problems. It's a proper set-and-forget auto.
Can I grow Auto Anesthesia in a 60x60cm tent?
Absolutely — this strain was practically designed for it. At 40–100cm tall, you'll have clearance even with a hanging light. Fit 2–4 plants depending on pot size. Just make sure your extraction fan keeps air moving around those dense buds.
What does Auto Anesthesia smell and taste like?
Sweet to sour, with herbal and pungent undertones. Fresh plants lean sweeter; cured buds develop a sharper, almost citric edge. The Northern Lights genetics bring a piney resin note, while Black Domina adds earthy depth.
Does Auto Anesthesia need staking or support?
Generally, no. The branches are thick and stocky enough to hold the dense buds without extra support. If you're pushing yields hard with heavy feeding, a light bamboo stake won't hurt — but most growers won't need one.
What light schedule should I use for Auto Anesthesia?
18 hours on, 6 hours off works well from seed to harvest. Some growers run 20/4 for extra growth. Unlike photoperiod strains, Auto Anesthesia flowers automatically regardless of light schedule — no need to switch to 12/12.
