Lemon Cream Kush

Lemon Cream Kush Autoflower Cannabis Seeds by Spliff Seeds

Lemon Cream Kush Autoflower is a feminised autoflowering cannabis seed strain from Spliff Seeds that produces tall, resin-heavy plants with bold citrus Kush aromas. Built from a cross of Medical Kush and Dutch Automatic, this auto reaches up to 300cm outdoors and finishes roughly 13 weeks after germination. She delivers dense indica-leaning buds coated in a thick, frosty layer of trichomes — the kind of resin production that makes your trimming scissors stick together within minutes. If you want to buy an autoflower that performs like a photoperiod, this is one of the more compelling options in the Spliff Seeds catalogue.

Why This Strain Deserves Your Garden Space

This strain stands out because it grows like a full-size photoperiod while keeping the convenience of autoflowering genetics. Most autoflowers are compact, quick little things you tuck into a corner. Spliff Seeds built this cultivar from Medical Kush — a resin-forward indica known for dense, trichome-caked flowers — and Dutch Automatic, their workhorse ruderalis hybrid that brings the autoflowering gene and solid pest resistance. The result is an auto that reaches up to 250cm indoors and a staggering 300cm outdoors.

That height is both the selling point and the honest limitation. Spliff Seeds themselves note that this strain can prove challenging to grow, and we'd agree — this isn't the auto you squeeze into a 60x60 tent. She's bushy, she's tall, and her flowering time runs longer than your average auto. But if you've got an outdoor plot or a spacious grow room, the payoff is worth it: dense indica nugs with a hard resin coat and that unmistakable lemon-cream Kush nose.

The aroma is the real standout. Crack open a cured jar and you get bright lemon zest up front — sharp, almost like fresh peel — followed by a creamy, sweet Kush undertone that rounds everything out. It smells like lemon curd on shortbread. If you're growing outdoors, your neighbours will notice, so plan accordingly.

How to Grow These Seeds Successfully

Outdoor cultivation is the best environment for this strain, thanks to her exceptional height potential and natural pest resistance. We'd pick an outdoor grow over indoor every time. At up to 300cm, she needs vertical room and lateral space that most tents simply can't offer. Outdoors, she can stretch freely, soak up direct sunlight, and her natural pest and mould resistance means she handles variable weather without drama. That said, if you do grow indoors, give her the tallest space you have and train early — LST (low-stress training) in the first few weeks can help manage that height before she runs away from you.

1. Germinate your seeds using the paper towel method or directly in a small pot of lightly moistened soil. Taproots typically emerge within 24–72 hours.
2. Transplant seedlings into their final container early — autos don't love being repotted. A 15–20 litre fabric pot works well for outdoor grows.
3. Use a light, airy growing medium. A mix of coco coir and perlite, or a quality organic soil with good drainage, gives roots the oxygen they need.
4. Go easy on nutrients during the vegetative phase. This strain is very sensitive to feeding, especially early on. Start at half the recommended dose and increase gradually only if the plant asks for it. Yellowing tips mean you've gone too far.
5. Provide 18–20 hours of light indoors throughout the entire lifecycle. Outdoors, plant after the last frost when days are long — she'll flower automatically regardless of light schedule.
6. Watch for bushy lateral growth. Remove lower fan leaves that block airflow to the interior canopy. Good airflow prevents the mould issues that dense indica buds can attract in humid conditions.
7. Begin flushing with plain water 1–2 weeks before harvest. At roughly 13 weeks from germination, check trichomes with a jeweller's loupe — milky white with a few amber heads signals peak harvest time.
8. Dry slowly in a dark room at 18–20 degrees Celsius and 55–60% humidity for 7–10 days, then cure in glass jars for at least 2 weeks. The lemon-cream aroma intensifies significantly during the cure.

What Makes This Strain Different from Other Autoflowers

This cultivar produces significantly more resin and grows two to three times taller than most competing autoflowers on the market. The auto market is flooded with compact, fast-finishing strains that sacrifice yield and potency for convenience. This Spliff Seeds creation goes the other direction. She takes a bit longer — 13 weeks is on the extended side for an auto — and she grows tall enough to rival some photoperiods. But the result is resin production that most autos can't touch, and yields that reflect her size rather than her autoflowering genetics.

Compared to something like a standard Northern Lights Auto, which finishes in 9–10 weeks and stays under 100cm, this is a different beast entirely. If you want a quick, stealthy grow, she's not your best bet. If you want an auto that produces photoperiod-quality buds with serious bag appeal, order a pack and give her the space she demands.

Aroma and Bud Quality

The dominant terpene profile delivers bright, genuine citrus peel tartness layered over a creamy Kush sweetness. The name tells you most of what you need to know, but it undersells the experience slightly. The lemon note isn't the artificial lemon of cheap cleaning products — it's genuine citrus peel, tart and bright. Underneath that sits a creamy, almost vanilla-like sweetness that's pure Kush genetics. The combination smells like a lemon dessert, which is exactly what Spliff Seeds was going for with this cross.

Bud structure is classic indica: dense, compact flowers that feel heavy for their size when you pick them up. The trichome coverage is where this strain really shines. Even mid-flower, the buds develop a visible frost that thickens into a hard, crystalline layer by harvest. If you're interested in making extracts or concentrates, the resin output makes her a strong candidate.

Honest Growing Considerations

Two common issues can reduce your results with this strain: nutrient sensitivity and sheer plant size. Like many Kush varieties, she reacts badly to heavy feeding — especially during veg. We've seen growers burn their plants in the first three weeks by following standard auto feeding schedules. Start at 50% strength and only increase if the plant shows signs of deficiency (light green leaves, slow growth). When in doubt, less is more.

Second, the size. A 250cm auto indoors is no joke. If your ceiling height is under 2 metres, you'll need to train aggressively or accept that this strain isn't suited to your space. Outdoors, she's a dream — but indoors, plan ahead or she'll outgrow your setup before you can react. According to Beckley Foundation research on cannabis cultivation practices, adequate vertical space is one of the most overlooked factors in indoor growing success.
