Sensi Amnesia XXL Auto by Sensi Seeds

Sensi Amnesia XXL Strain Info

Looking for a cannabis seed that packs a punch, smells like heaven, and grows like a dream?

The Sensi Amnesia XXL strain from Sensi Seeds is a powerful sativa-dominant autoflower that knows exactly how to light up your grow room—and your mind.

This beauty is born from a mix of original Amnesia genetics, retrocrossed for stability and then blended with a Ruderalis to give it that sweet autoflower magic.

Think of it like a rockstar with a smart calendar—she doesn’t need anyone to flip the lights to start the show, she blooms all on her own, right on time.

Once those pistils show up, the countdown begins: just 70 to 85 days until harvest from the first signs of flowering.

And don’t be fooled by the XXL—this girl keeps things compact.

She grows between 80 to 100 cm (2.6 to 3.3 ft) indoors and up to 120 cm (3.9 ft) outdoors, so she won’t take over your whole grow tent or balcony.

What she lacks in height, she makes up for in bud structure.

We’re talking dense, stacked nuggets with thick bracts and a frosting of resin that sparkles like morning dew in the forest.

And yeah, she smells good enough to make your mouth water—sweet, lemony citrus with a zingy twist of haze.

Flowering Time & Yield

The Sensi Amnesia XXL seeds produce a crop that’s easy to handle and seriously rewarding.

Growers indoors can expect around 450 to 500 grams per square meter (15.8 to 17.6 oz), while outdoor setups usually pull in 200 to 250 grams per plant (7 to 8.8 oz).

That’s plenty of sticky buds to keep your jars full and your mood lifted.

Just remember—she's not in a rush.

Her flowering period stretches a bit longer than average, but trust us, the wait is more than worth it.

Effects and Aroma

One hit of this flower and you're floating somewhere between a warm beach and the top of a mountaintop at sunrise.

The high is pure sativa goodness—uplifting, cerebral, euphoric, and it sticks with you for hours without dragging you down.

It’s the kind of buzz that makes even the most stressful days feel like a breeze, turning frowns into full-on dance parties.

The aroma hits you first—bright citrus, sweet lemon peel, and a dash of earthy spice that lingers in the room long after the jar’s closed.

On the tongue, it’s sweet at first, like biting into a lemon drop candy, then evolves into a fruity haze and finishes with a tangy lemon twist that coats your lips.

This is not your average autoflower—she’s got personality, power, and plenty of flavor to go around.

If you're looking for autoflowering cannabis seeds that deliver a top-tier experience from grow to smoke, Sensi Amnesia XXL seeds might just be your new obsession.

Pro Tips & What We Love Most

We always recommend giving Sensi Amnesia XXL a bit of breathing room—those big fan leaves can block airflow if left unchecked.

Light defoliation during veg and early bloom helps the buds fatten up and lowers the risk of mold or mildew creeping in.

Thanks to its Ruderalis lineage, this strain handles pests and diseases like a champ—it's got solid resistance and rarely needs intervention.

She doesn’t throw tantrums with a bit of heat or unexpected humidity, which makes her a solid choice for outdoor grows in warm, temperate, or even slightly continental climates.

With good airflow and moderate nutrients, she thrives in soil, coco, or hydro, so you’ve got options depending on your setup and style.

The sweet spot for outdoor grows is during the warmer months, ideally with temps around 22-28°C (72-82°F).

While she’s considered easy to grow and pretty forgiving, we’ve noticed she rewards a little extra care with denser buds and even stickier trichomes.

What we really love most about the Sensi Amnesia XXL strain is how she combines old-school Amnesia character with modern autoflowering performance—it’s like getting the best of both worlds without the headache of managing light schedules.

Frequently Asked Questions

Is Sensi Amnesia XXL sativa or indica?

Sensi Amnesia XXL is a sativa-dominant strain, with a 70% sativa and 30% indica genetic profile.

This means you'll get the classic sativa effects—uplifting, energetic, and mentally stimulating—without completely missing out on the slight body relaxation that indica provides.

Sativas are known for their tall structure, long flowering times, and heady highs, while indicas usually stay shorter, flower quicker, and give more of a body-heavy effect.

Sensi Amnesia XXL leans into that sativa heritage with its cerebral buzz and lemony haze aroma, but thanks to its Ruderalis influence, it stays compact and easy to manage like an indica.
