Purple Lemonade Auto Cannabis Seeds by Royal Queen Seeds
Purple Lemonade Auto is an autoflowering cannabis seed variety from Royal Queen Seeds that crosses Purple Haze, Lemon Skunk, and Sweet Skunk Auto into one compact, fast-finishing plant with striking purple and pink buds. If you want a grow that looks as good as it smells — citrus rind, sweet berries, and a deep fruity funk — this is the seed to start with. These buds photograph like they were designed for it.
Why Purple Lemonade Auto Seeds Deserve a Spot in Your Garden
Three parent strains, zero fuss. Royal Queen Seeds crossed Purple Haze (the classic sativa-leaning legend), Lemon Skunk (sharp citrus terps, solid structure), and Sweet Skunk Auto (the ruderalis backbone that makes the whole thing automatic). The result is a 70% indica / 30% sativa hybrid that doesn't need light-cycle changes to flip into flower. You germinate, you wait roughly 10-12 weeks, and you harvest. That's it.
What makes this one stand out from the dozens of other autos on the market? The colours, for a start. Purple Lemonade Auto produces buds that range from forest green through deep purple to vibrant tiger orange, with pink highlights scattered across the calyxes. This isn't a marketing photo trick — the anthocyanin pigments in this genetic line express strongly, especially when night temperatures drop a few degrees during late flower. According to research published in the journal Molecules, anthocyanins are naturally occurring plant pigments responsible for red, purple, and blue colouration in many plant species (Khoo et al., 2017, PMC5613902). In Purple Lemonade Auto, those pigments show up reliably across most phenotypes.
The honest limitation? She's not the biggest yielder in the RQS autoflower catalogue. At up to 475 g/m² indoors and 130-180 g/plant outdoors, she's respectable but not record-breaking. If maximum weight per watt is your only metric, something like Royal Queen Seeds' HulkBerry Auto might edge her out on raw numbers. But if you want a complete package — looks, flavour, speed, and a well-balanced effect profile — Purple Lemonade Auto is hard to beat.
Choosing Your Purple Lemonade Auto Seed Pack
Purple Lemonade Auto seeds come in packs of 1, 3, 5, or 10. Here's how we'd think about it:
| Pack Size | Best For |
|---|---|
| 1 seed | Test run in a small tent or single pot on a balcony. Low commitment. |
| 3 seeds | A proper small grow — enough to select the best phenotype and still get a decent harvest. |
| 5 seeds | Fill a 60x60 or 80x80 tent comfortably. Our pick for most indoor growers. |
| 10 seeds | Multiple runs, outdoor plots, or pheno-hunting across a full season. |
We'd grab the 5-pack for a first run. It gives you enough plants to see the variation in colour expression between phenotypes — some lean more purple, others show stronger orange tones — without overcommitting on space.
Growing Purple Lemonade Auto Seeds: What to Expect
Purple Lemonade Auto seeds have excellent germination rates according to Royal Queen Seeds. Healthy seedlings vegetate for approximately 3 weeks before automatically transitioning into bloom — no timer adjustments, no light deprivation, no stress. During early bloom, plants stretch considerably. Indoors, expect final heights of 60-100 cm. Outdoors, she can reach up to 120 cm.
Flowering takes 7-9 weeks once it starts, putting your total seed-to-harvest timeline at roughly 10-12 weeks. That speed makes Purple Lemonade Auto the best autoflower for squeezing in an extra harvest at the end of the outdoor season, or for running perpetual cycles in a small indoor space where you can't afford to wait 4+ months.
One thing we've heard from growers: she responds well to LST (low-stress training) during the veg phase to open up the canopy and expose more bud sites to light. Don't top her — autos don't have time to recover from high-stress techniques. Gentle bending and tying is the way.

Aroma and Flavour Profile of Purple Lemonade Auto
Crack open a cured jar and the first thing that hits you is sharp lemon zest — proper citrus peel, not artificial lemon drop sweets. Underneath that, there's a layer of ripe berries and a subtle sweetness that rounds it all out. The Lemon Skunk parentage drives the citrus, while Purple Haze contributes the fruity, almost floral undertones. It's a complex nose that fills a room quickly, so factor in a carbon filter if you're growing indoors and discretion matters.
On the palate, growers report the same citrus-forward profile with a sweet, candy-like finish. The tight bud structure traps terpenes effectively, which means properly dried and cured Purple Lemonade Auto buds hold their aroma for months in a sealed jar. According to research on cannabis strain naming conventions, strain names like Purple Lemonade are often derived from sensory characteristics including smell and taste (Vergara et al., 2018, PMC6275121) — and in this case, the name genuinely delivers.
Effects of Purple Lemonade Auto
Purple Lemonade Auto produces a well-balanced effect that leans towards physical relaxation thanks to its 70% indica genetics, with enough sativa influence to keep things mentally present. THC levels sit in the 18-22% range — strong enough to be properly felt, but not so overwhelming that a moderately experienced user can't function. The onset is typically calm and gradual rather than an immediate head-rush.
The indica dominance means the body effect is noticeable: muscles loosen, tension drops, and there's a general sense of physical ease. The 30% sativa side keeps a gentle creative edge in play, making this a strain that works well in the evening without completely switching you off. Traditionally, indica-dominant hybrids like this have been associated with relaxation and unwinding, and Purple Lemonade Auto fits that profile neatly.
Watch out for dry mouth — it's the most commonly reported side effect with this strain. Keep water nearby. And if you're newer to cannabis, the 18-22% THC range means starting with a small amount and waiting is the sensible approach.
Complete your grow setup with a compact tent and LED light if you're running Purple Lemonade Auto indoors. Her 60-100 cm height fits comfortably in an 80x80 grow tent, and a good carbon filter is worth the investment given her strong terpene output. Growing outdoors? A fabric pot in the 15-20 litre range gives roots enough room without wasting soil on a plant that stays under 120 cm.
How to Grow Purple Lemonade Auto Seeds
- Germinate your Purple Lemonade Auto seeds using the paper towel method or by placing them directly into moist, light soil. Royal Queen Seeds reports excellent germination rates with this variety. Keep temperatures between 22-25°C during germination.
- Transplant sprouted seeds into their final container immediately — autos don't like being repotted. A 15-20 litre fabric pot with well-draining soil is a solid choice. The 3-week veg phase is short, so every day of root stress counts.
- Provide 18-20 hours of light per day throughout the entire lifecycle. Autoflowers don't need a light-cycle change, but they do need consistent, strong light to reach their yield potential of up to 475 g/m² indoors.
- Begin low-stress training during week 2-3 by gently bending the main stem and tying it down. This opens the canopy and encourages lateral branching. Do not top or FIM — autos recover too slowly from high-stress techniques.
- Watch for the pre-flowering stretch around week 3-4. Plants can double in height during this phase, reaching 60-100 cm indoors. Adjust your light height accordingly to prevent bleaching.
- Feed lightly during veg and increase phosphorus and potassium during flower. Autos are sensitive to overfeeding — if leaf tips start burning, back off by 25%.
- Harvest at 10-12 weeks from germination when trichomes are mostly milky with some amber. Dry in a dark room at 18-20°C and 55-60% humidity for 7-10 days, then cure in sealed jars for at least 2 weeks to develop the full lemon and berry terpene profile.
Frequently Asked Questions
What is Purple Lemonade Auto?
Purple Lemonade Auto is an autoflowering, feminised cannabis seed variety from Royal Queen Seeds. It's a cross of Purple Haze, Lemon Skunk, and Sweet Skunk Auto, producing 70% indica / 30% sativa plants that go from seed to harvest in 10-12 weeks with striking purple, pink, and orange buds.
How long does Purple Lemonade Auto take from seed to harvest?
Expect 10-12 weeks total. The veg phase lasts approximately 3 weeks before automatic flowering begins, and the flowering stage runs 7-9 weeks. No light-cycle changes needed — she transitions on her own.
What yields can I expect from Purple Lemonade Auto?
Indoors, Purple Lemonade Auto can produce up to 475 g/m² under optimal conditions. Outdoors, expect 130-180 g/plant. Yields depend heavily on light intensity, pot size, and whether you use low-stress training during veg.
Why aren't my Purple Lemonade Auto buds turning purple?
Anthocyanin pigments — the compounds responsible for purple colouration — express more strongly when night temperatures drop to around 15-18°C during late flower. If your grow environment stays consistently warm, buds may lean more green. The flavour and potency remain unaffected.
Is Purple Lemonade Auto good for beginners?
Yes. Autoflowers remove the complexity of light-cycle management, and Purple Lemonade Auto's compact 60-100 cm indoor height makes her manageable in small spaces. Just avoid overfeeding and skip high-stress training techniques — gentle LST is all she needs.
How does Purple Lemonade Auto compare to other purple autoflowers?
Most purple autos lean grape or berry on the nose. Purple Lemonade Auto's Lemon Skunk parentage gives her a distinctive citrus-forward profile that finishes with sweet fruit — a combination that's uncommon in the autoflower market. She's also faster than many competitors at 10-12 weeks total.
