An Award-Winning Strain
Purple Lemon is a genuine competition winner, taking 1st Place in the Sativa category at Spannabis 2017, one of Europe’s most respected cannabis cups, and following it with a 3rd Place, Sativa finish at the Cannabis Cup 2018. Those podium results speak to stable, high-quality genetics and a consistent, standout finish.
For a grower, that track record is a useful signal of quality and reliability, which is exactly what you want when you invest a full cycle into a plant. You can find it alongside our other award-winning cannabis seeds if you want more proven performers.
Climate and Where to Grow It
Purple Lemon does best in a temperate climate with plenty of light and good airflow. It is a sturdy, adaptable plant that performs both outdoors in a warm season and in a controlled indoor tent, reaching a medium 1.5 m, so it fits most spaces without demanding a tall room as it moves into flower.
Outdoors it finishes around October and rewards a good spot with 450–550 g per plant, while indoors it produces a solid 350–450 g/m². Those are respectable numbers for a manageable plant, but they depend on light, pot size and canopy health, so give it room and feed it steadily to reach the top of the range.
Indoors, aim for daytime temperatures around 70–82°F (21–28°C) and keep steady airflow moving through the canopy. Cooler nights late in flower help bring out its purple hues from the Purple Kush side. Its resinous buds hold moisture, so keep humidity in check as flowering fills in.
Growing Feminized Photoperiod Seeds
As a feminized strain, every seed grows into a flowering female, so there is no need to sex the plants or remove males. That keeps the grow simple and means no wasted time or tent space on plants you would only cull later, which is part of why Purple Lemon is beginner-friendly.
Being a photoperiod plant, it flowers on a light change rather than on age. Grow it under a long day (around 18 hours of light) through the vegetative stage, then switch to a 12/12 cycle to trigger flowering. A longer veg builds a bigger frame and a heavier harvest, while a shorter veg keeps the plant more compact in a small space.
Feeding Schedule (EC Guide)
This is a resinous, balanced hybrid that sets dense, sticky buds, so feed it steadily but without overdoing it. Start low, build up as the plant asks for more, and taper right off for the final flush so the zesty citrus-and-lemon flavor comes through clean and the smoke finishes smooth.
| Stage | EC (mS/cm) | Notes |
|---|---|---|
| Seedling | 0.4–0.6 | Very light feed, focus on healthy root growth |
| Vegetative growth | 0.8–1.2 | Build the frame, raise nitrogen gradually |
| Early flower | 1.2–1.4 | Shift toward bloom nutrients (P and K) |
| Full flower | 1.4–1.6 | Peak bloom feed while the sticky buds swell |
| Flush | 0.0–0.4 | Plain water for the final 1–2 weeks |
Flowering and Harvest
Once you flip to 12/12, bloom runs about 8–10 weeks. As a balanced hybrid it stays sturdy and bushy, filling in dense, resin-coated buds that gain weight and often take on purple tones through the second half of flowering, blending the colour of its Purple Kush side with the frosty resin of Lemon Skunk.
Give the colas light support as they fatten, and keep the canopy open so light reaches the lower flowers. Harvest when most trichomes have turned cloudy with a few amber heads for the fullest expression, and run a short plain-water flush in the last week or two before you cut the plant down.
Drying and Curing
Dry whole plants or branches in a dark room at around 60°F (15–18°C) and 55–60% humidity for 7–14 days, until the thin stems snap rather than bend. A slow, even dry stops the resinous buds staying damp in the middle while the outside dries out, which protects both the zesty citrus aroma and the resin.
Then cure the trimmed buds in sealed jars, burping them daily for the first week and letting them settle for three to four weeks. A proper cure brings the citrus, fruity and sweet notes forward and smooths the smoke, which is exactly what this cup-winning Skunk-lineage hybrid deserves.
What to Do With Your Trim
Don’t bin the sugar leaves you remove while manicuring. Purple Lemon is a resinous plant, so the trim is excellent for dry sift, bubble hash or rosin, giving you a bonus run of zesty, citrus-scented concentrate from material most growers would otherwise throw away.
Flavor and Terpenes
Purple Lemon lives up to its name: a bright, zesty citrus and lemon flavor over an earthy, herbal base with a soft, fruity sweetness. It is a lively, mouth-watering taste that balances the sharp Lemon Skunk side with the deeper Purple Kush notes, carried straight from its parents into the cured flower.
Its terpene profile is led by limonene and citral for the zesty citrus and lemon, myrcene for a soft, fruity base, caryophyllene for an earthy, peppery backbone, pinene for a fresh, herbal top note and linalool for a gentle floral touch. Together they frame the bright citrus-over-earth character that won the strain its cup recognition.
Effects and Best Use
With its balanced 50/50 genetics, Purple Lemon is reported as creative, energetic and uplifted, a bright, mood-lifting high that sparks creativity and sociability while a mild body relaxation keeps it grounded. That balance makes it versatile, working for creative projects or an active, social afternoon without tipping into heaviness.
At a medium 15–22% THC it is potent but approachable, which suits both newer users and anyone who prefers a balanced, manageable high. That character, the zesty citrus flavor, the award-winning pedigree and the colourful, resinous plant are exactly why growers reach for Purple Lemon.
Common Problems and Pro Tips
The main thing to watch with Purple Lemon is humidity around its resin-heavy buds, which can trap moisture, so bud rot is the most common problem in the final weeks of flower. Keep humidity moderate through the second half of bloom, run steady airflow, and a light defoliation of the inner canopy helps air reach the thickest colas as they fill out.
Bringing out its colour is the other thing to plan for. To coax the purple tones from its Purple Kush side, let night-time temperatures drop a little in late flower, which encourages the colour without harming the plant. Light training early also keeps the balanced hybrid canopy even, so both the upper and lower buds fill out well.
As a pro tip, protect the zesty citrus flavor that makes this cup-winner special: keep the feed moderate rather than heavy, since overfeeding can mute the limonene and citral, and give it a clean plain-water flush in the final one to two weeks. Follow the trichomes rather than the calendar at the end, then dry slowly and cure for three to four weeks to do its award-winning genetics justice.
FAQ
What awards has Purple Lemon won?
Purple Lemon took 1st Place in the Sativa category at Spannabis 2017, one of Europe’s most respected cannabis cups, and followed it with a 3rd Place, Sativa finish at the Cannabis Cup 2018. Those podium results reflect stable, high-quality genetics and a consistent finish, reassuring whether you are a first-time or experienced grower.
Is Purple Lemon indica or sativa?
Purple Lemon is a balanced hybrid, at 50% indica and 50% sativa, from its Purple Kush and Lemon Skunk parents. That even split shows in a creative, energetic, uplifted high from the Lemon Skunk side, grounded by a mild body relaxation from Purple Kush, so it stays bright and versatile rather than heavy or racy.
What does Purple Lemon taste like?
True to its name, Purple Lemon has a bright, zesty citrus and lemon flavor over an earthy, herbal base with a soft fruity sweetness. Limonene and citral drive the citrus and lemon notes, myrcene adds the fruity base, and caryophyllene brings an earthy, peppery backbone that balances the sharp Lemon Skunk brightness.
What is Purple Lemon’s THC level?
Purple Lemon carries a medium THC of 15–22%, potent but approachable rather than overpowering. That level drives a creative, energetic, uplifted effect that stays bright and balanced, so it suits both newer users and anyone who wants a versatile, manageable high rather than the heaviest possible hit.
How long does Purple Lemon take to flower?
About 8–10 weeks once you switch to a 12/12 light cycle, with outdoor plants finishing around October. It is a photoperiod feminized strain, so it blooms on the light change rather than on age, filling in dense, resinous buds that often take on purple tones through the second half of flowering as they mature.
Does Purple Lemon turn purple?
Often, yes. Its Purple Kush heritage gives it a genuine tendency toward purple hues, which show up most in the buds and leaves late in flower. Cooler night-time temperatures in the last couple of weeks of bloom help bring that colour out, though the exact shade varies from plant to plant and grow to grow.
