Auto American Pie Cannabis Seeds by Pyramid Seeds
Auto American Pie is an autoflowering feminised cannabis seed from Pyramid Seeds that crosses two heavyweights — White Widow and Power Plant — with ruderalis genetics for fully automatic flowering. The result is a strain that hits up to 20% THC, which is remarkably potent for an autoflower, while keeping the growing process dead simple. We've had customers come back specifically for this one after trying it alongside other autos in the same tent. It's that kind of seed.
Why Auto American Pie Seeds Stand Out
Not every autoflower breeding project ends well. You cross a photoperiod legend with ruderalis and sometimes the offspring loses everything that made the parent special — the potency drops, the flavour goes flat, the yields shrink. Pyramid Seeds avoided all three pitfalls with Auto American Pie. They took White Widow (famous for resin production and that frosted, trichome-heavy look) and Power Plant (known for vigorous growth and solid yields), then bred in the autoflowering trait without gutting what made those parents worth growing in the first place.
The 20% THC ceiling is the headline number, and it deserves attention. Most autoflowers sit comfortably in the 12-16% range. Hitting 20% puts Auto American Pie in photoperiod territory, which is exactly what makes it unusual. You get the convenience of no light schedule changes, no sexing, no fuss — and you still end up with buds that carry proper weight behind them.
Visually, the buds grow long and dense, absolutely caked in trichomes. If you've grown White Widow before, you'll recognise that crystalline shimmer on the calyxes. The terpene profile leans sweet and earthy, with enough complexity to keep things interesting through the cure. Crack open a jar after two weeks of curing and you'll notice a warm, slightly spicy sweetness — nothing one-dimensional about it.

How to Grow Auto American Pie Seeds
Auto American Pie is one of those strains where the growing process is genuinely straightforward. She's not fussy about medium — soil or hydro both work — and she doesn't need a specific light cycle flip to start flowering. That said, a few decisions early on make the difference between a decent harvest and a properly impressive one.
- Germinate your seeds using the paper towel method or plant directly into a small pot of moist, lightly fertilised soil. Autoflowers don't love transplanting, so starting in the final container (11-15 litres) saves stress on the root system.
- Provide 18-20 hours of light per day from seedling through harvest. Auto American Pie doesn't need a 12/12 flip — she'll flower on her own schedule, typically starting around week 3-4 from germination.
- Keep humidity around 60-70% during the vegetative stage, then drop to 40-50% once flowers start forming. This helps prevent mould in those dense, resinous buds.
- Feed lightly during the first two weeks — autoflowers are sensitive to nutrient burn early on. Increase feeding gradually as she enters the flowering stretch, focusing on phosphorus and potassium during mid-to-late flower.
- Under a 600W light indoors, you can push yields up to 500g/m². Outdoors, expect around 100g per plant. She'll stay between 60-160cm tall, so she fits comfortably in most grow tents without height becoming an issue.
- Harvest when trichomes shift from clear to milky-white with some amber. Given her White Widow genetics, the trichome coverage will be heavy — use a jeweller's loupe or digital microscope to time it right.
Indoor vs. Outdoor: Where Auto American Pie Performs Best
Auto American Pie does well in both environments, but the numbers tell slightly different stories. Indoors under a 600W setup, you're looking at up to 500g/m² — that's a strong return for an autoflower, and the controlled environment lets you dial in the conditions to maximise trichome production. The 60-160cm height range means she won't outgrow a standard 120cm tent, though the taller phenotypes might need some light LST (low-stress training) to keep the canopy even.
Outdoors, yields drop to around 100g per plant, which is typical for autos that don't get the same light intensity as an indoor setup. The trade-off is simplicity — plant her in a sunny spot after the last frost, water regularly, and let her do her thing. Greenhouse growers get the best of both worlds: natural light with weather protection. If you're in a climate with short summers, autoflowers like this one are your best option since she'll finish regardless of day length.
One honest limitation: the 60-160cm height range is quite broad. You might get a compact 60cm plant or something nearly three times that size. Phenotype variation is real with autos, and Auto American Pie is no exception. If vertical space is tight, plan for the taller end and train accordingly.
Auto American Pie Compared to Similar Autoflowers
| Feature | Auto American Pie | Typical Auto White Widow | Average Autoflower |
|---|---|---|---|
| THC | Up to 20% | 15-18% | 12-16% |
| Indoor Yield | Up to 500g/m² | 350-450g/m² | 300-400g/m² |
| Outdoor Yield | Up to 100g/plant | 60-80g/plant | 50-80g/plant |
| Height | 60-160cm | 50-100cm | 50-120cm |
| Genetics | White Widow x Power Plant x Ruderalis | White Widow x Ruderalis | Varies |
The Power Plant genetics give Auto American Pie a noticeable edge in vigour and yield over a standard Auto White Widow. You're essentially getting the resin production and potency of White Widow combined with the robust growth patterns of Power Plant, all wrapped in an autoflowering package. If you've grown Auto White Widow before and wanted more from it, this is the logical next step.
Complete your grow setup with a proper grow tent and ventilation kit — Auto American Pie's heavy trichome production means strong aromas during late flower, so a carbon filter is worth having. Pair with quality cannabis nutrients designed for autoflowers to get the most from those 500g/m² potential yields.
What We've Seen
We've been selling cannabis seeds since 1999, and the autoflower category has changed beyond recognition in that time. Early autos were, frankly, a bit disappointing — low THC, airy buds, underwhelming yields. Modern autos like Auto American Pie are a completely different animal. The fact that Pyramid Seeds managed to preserve 20% THC in an autoflowering format shows how far breeding has come.
Customers who've grown this strain tend to comment on two things: the trichome coverage and how little attention the plant needs. She's genuinely low-maintenance. We've had first-time growers pull respectable harvests from Auto American Pie without any training techniques at all — just good light, regular watering, and basic nutrients. That's the beauty of well-bred autos.
The one thing to watch: don't overwater during the first two weeks. Autoflowers have a shorter vegetative phase, so any early stress costs you more than it would with a photoperiod plant. Small pot, moist but not soaked, let the roots find their feet. After that, she's remarkably forgiving.
According to research reviewed in Marijuana: Current Concepts (PMC, 2013), studies on cannabis provide evidence of both positive and varied effects from consumption, underscoring the importance of understanding individual strain characteristics like cannabinoid content and terpene profiles when selecting seeds.
Frequently Asked Questions
How long does Auto American Pie take from seed to harvest?
Expect roughly 9-10 weeks from germination to harvest. She begins flowering automatically around week 3-4 without any light schedule change. The exact timing depends on growing conditions, but most growers report chopping between days 63 and 70.
Is 20% THC really achievable in an autoflower?
Yes, though it requires good growing conditions — proper lighting (600W or equivalent LED), correct nutrients, and stable temperatures. Pyramid Seeds measured Auto American Pie at up to 20% THC, which puts her at the top end of what autoflowers currently achieve. Not every plant will hit the ceiling, but the genetic potential is there.
Can I grow Auto American Pie in a small tent?
She fits most standard tents. The height range is 60-160cm, so even the taller phenotypes stay manageable in a 120-150cm tent. If you get a taller plant, gentle LST (bending and tying branches) keeps her within bounds without stressing her.
Does Auto American Pie need special nutrients?
No special feeding regime required. Standard cannabis nutrients work fine — just go easy during the first two weeks since autoflower seedlings are sensitive to overfeeding. Switch to bloom nutrients when you see the first pistils forming, and taper off feeding about a week before harvest for a cleaner finish.
What does Auto American Pie smell and taste like?
The terpene profile is sweet and earthy with a warm, slightly spicy undertone. The White Widow parentage contributes a resinous, almost piney sharpness, while Power Plant adds a fuller, more rounded sweetness. After a proper two-week cure, the flavour becomes noticeably smoother and more complex.
Can I grow Auto American Pie outdoors in a cooler climate?
Autoflowers are your best bet for short or cool summers since they flower based on age, not day length. Auto American Pie handles outdoor conditions well, though yields outdoors (up to 100g per plant) are lower than indoor grows. Plant after the last frost and give her the sunniest spot you've got.
How many seeds come in a pack of Auto American Pie?
Each pack contains 5 feminised autoflowering seeds. All seeds are feminised, so you won't need to identify and remove males — every seed should produce a flowering female plant.
