Psycho XXL Auto MIX

Psycho XXL Auto MIX: 4 Sativa Autoflower Powerhouses in One Box

The Psycho XXL Auto MIX is a feminized autoflowering seed collection from BSF Seeds that packs four of their strongest sativa-leaning autoflowers into a single 12-seed pack — three seeds per strain, separated into individual bubbles so you know exactly what you're planting. If you grow sativas and you want variety without ordering four separate packs, this is the shortcut.

What's Inside the Psycho XXL Autoflower Seed Mix

Each pack contains 12 feminized autoflowering cannabis seeds — three per variety, individually packaged so there's zero guesswork. Here's what you're working with:

The standout here is Amnesia XXL Auto — 500g/m² from an autoflower is genuinely impressive. That's territory usually reserved for photoperiod plants with a full veg cycle. AK XXL Auto is the fastest of the four at roughly 70 days, which makes it the one to watch if you're impatient or running a tight schedule.

Why This Autoflowering Sativa Seed Mix Stands Out

We've sold a lot of mixed seed packs over the years, and the common complaint is always the same: you open the bag and have no idea which seed is which. BSF Seeds actually thought about this — each variety sits in its own labelled bubble. Sounds basic, but most mix packs don't bother, and you end up with twelve identical-looking seeds and a guessing game come harvest.

The four strains lean heavily sativa, which means you're getting cerebral, energising effects rather than couch-lock. Amnesia XXL Auto carries that classic Haze character — sharp lemon and pine on the nose, the kind of smell that fills a room when you crack open a jar. If you've grown Amnesia in photoperiod form before, expect a similar terpene profile in a fraction of the time.

One honest note: "XXL" yields printed on seed packs always assume optimal conditions — good light (600W HPS or 250W+ LED equivalent), proper nutrition, and stable climate. You'll get solid results in a basic tent setup, but don't expect 500g/m² from a windowsill grow. The numbers in the table above are ceilings, not guarantees. That said, BSF Seeds' XXL autoflower genetics are genuinely above average in the yield department compared to, say, a standard Royal Queen Seeds auto.

Growing the Psycho XXL Auto MIX: Autoflower Seed-to-Harvest

All four strains are autoflowering and feminized, so there's no light-cycle switching and virtually zero risk of male plants. Here's how to get the most from them:

1. Germinate using the paper-towel method or directly in a small pot of lightly moistened seedling soil. Tap roots typically emerge within 24–72 hours.
2. Transplant seedlings into their final containers early — 11L to 15L fabric pots work well. Autoflowers don't recover from transplant shock as gracefully as photoperiods, so minimise root disturbance.
3. Run your lights on an 18/6 or 20/4 schedule from seedling through harvest. These strains don't need a 12/12 flip — they'll start flowering on their own around week 3–4.
4. Feed lightly during the first two weeks, then ramp up with a bloom-oriented nutrient schedule once you see pre-flowers forming. Autoflowers are sensitive to overfeeding, so start at half the manufacturer's recommended dose.
5. Keep relative humidity around 50–60% during veg, dropping to 40–50% once buds start fattening. Good airflow is critical — sativa-dominant plants can stretch tall, and dense canopy centres invite mould.
6. Harvest when trichomes shift from clear to milky-white with a few amber heads. For these sativa-leaning strains, harvesting on the earlier side (mostly milky, minimal amber) preserves the uplifting character.

The entire cycle from germination to chop runs 70–90 days depending on the strain. AK XXL Auto finishes fastest at around 70 days. Amnesia XXL Auto can push closer to 90. If you're growing all four side by side, expect a staggered harvest window — which is actually quite handy, because it means you're not processing twelve plants on the same afternoon.

Sativa Autoflower Seeds: Aroma, Flavour, and What to Expect

The terpene profiles across these four strains are where the variety really shines. Amnesia XXL Auto leads with that unmistakable Haze nose — sharp lemon zest layered over resinous pine, with a faintly sweet undertone that rounds it out. It's the kind of aroma that sticks to your fingers after trimming. According to a review in the journal Phytochemical Modulators of Nociception, linalool — a terpene commonly found in cannabis — "exhibits marked anxiolytic activity, which is potentially useful in clinical contexts where pain is accompanied by psycho-emotional distress" (PMC12389225). Several of these sativa strains contain linalool alongside their dominant citrus terpenes.

Orange Blossom XXL Auto is the most aromatic of the bunch in our experience — sweet citrus with a floral quality that's closer to actual orange blossom than the generic "citrus" label most seed banks slap on everything. Lemon King XXL Auto is sharper, more acidic, like lemon peel rather than lemon candy. AK XXL Auto sits in earthier territory with a complex, layered terpene profile that develops depth during a proper two-week cure.

The effects across all four strains lean cerebral and energising — these are sativas, after all. Amnesia XXL Auto in particular is known for its intensity. BSF Seeds describes it as "very profound" and "more cerebral than physical." If you're used to indica-dominant autoflowers and their heavy body effects, this mix will feel like a different category entirely.

Who Should Grow This Autoflowering Cannabis Seed Mix

Start with this if you know you like sativas but haven't nailed down a favourite strain yet. Twelve seeds across four varieties gives you a proper tasting menu — enough to run a full cycle of each and figure out which one earns a permanent spot in your rotation. It's also solid value compared to buying four individual packs of three.

If you're a pure indica grower who wants something heavy and sedating, this isn't your pack. Every strain here leans sativa, and the effects reflect that. There's no indica "anchor" in the mix to balance things out. That's a feature, not a flaw — but it's worth knowing upfront.

For outdoor growers in northern climates: autoflowers are your best bet for finishing before autumn rains set in. A 70–90 day cycle means you can germinate in late May and harvest by August, well ahead of the mould-friendly weather that kills photoperiod sativas in places like the Netherlands or the UK. Amnesia XXL Auto has good natural resistance to pests and diseases, which helps if your garden isn't exactly a controlled environment.
