Skunk XL Feminized Seeds – Royal Queen Seeds · Balanced Hybrid with 17% THC · High Yield & Classic Skunk Flavor

Skunk XL feminized seeds from Royal Queen Seeds bring the legendary genetics of a cannabis icon into your grow space, delivering massive yields of dense, resinous buds with a perfectly balanced high and that unmistakable sweet-skunk aroma.

Are You Still Struggling With Weak Yields and Bland-Tasting Buds?

Maybe you’ve tried strains that promised big harvests but delivered wispy, airy flowers that barely fill a jar. Or perhaps you’ve settled for easy-to-grow varieties that lack that complex, head-turning flavor profile you’re chasing. You spend weeks nurturing your plants, only to be let down by inconsistent results or a finish that doesn’t live up to the hype.

That Frustration of Watching Your Harvest Fall Short

It’s disheartening to see your hard work result in a mediocre smoke. You might find yourself doubting your skills, wondering if you did something wrong. The time, the energy, the electricity—all for a product that doesn’t spark joy or deliver the experience you were promised. That lingering doubt can make you hesitant to start your next grow, turning what should be a rewarding hobby into a source of stress.

Skunk XL: The Legendary Strain That Delivers on Every Promise

Meet Skunk XL, the feminized evolution of the original Skunk #1 x Afghan cross that laid the foundation for modern cannabis. This isn’t just another strain; it’s a proven champion. With a flowering time of just 55–60 days, it produces colossal yields of up to 650 g/m² indoors and 675 g per plant outdoors. Its dense, chunky buds are blanketed in trichomes, bursting with a flavor profile of candy, earth, and ripe fruit, leading to a clear-headed, stoned high that’s both uplifting and relaxing.

Before You Grow Skunk XL

Before you even crack a seed, set yourself up for success. Skunk XL thrives in a stable environment with consistent light and temperature. Whether you’re using soil or a hydro setup, start with a high-quality, well-aerated medium. For a hassle-free start, Pro Organic Grow ( BioThrive Grow ) speeds up rooting and builds a resilient root system, giving your seedlings the best possible foundation.

• Germinate seeds in a moist, dark environment at 22–25 °C (71.6–77 °F)
• Choose your medium: light mix soil or coco for optimal drainage
• Prepare pots of 11–20 L depending on your final plant size goal
• Set up your 600W HPS or equivalent LED with a 18/6 light cycle for veg
• Ensure good airflow from day one to prevent mold and build strong stems

During the Grow: Vigour, Structure, and Care

Skunk XL is a joy to watch grow. It exhibits a strong, compact structure with minimal stretching during pre-flower, making it ideal for SCROG or SOG setups. Its balanced 50% sativa / 50% indica genetics mean it grows tall enough for impressive yields (up to 2 m / 6.56 ft outdoors) but remains manageable indoors (0.60–1.00 m / 1.97–3.28 ft). In sustained growth, Bio Heaven BioBizz keeps leaves lush and green, maximizing photosynthesis and plant vigor without overloading with nitrogen.

Monitor your plants for nutrient demand; Skunk XL is known to be a bit of a feeder. Adjust your schedule as needed, but avoid overfeeding, which can lead to nutrient burn. This strain is mold-resistant and handles both temperate and Mediterranean climates with ease, making it a reliable choice for outdoor grows in regions like the UK or Southern Europe.

After Harvest: Results and Maintenance

Once you’ve harvested and cured your buds, the results speak for themselves. You’ll be rewarded with a mountain of dense, sticky nugs that boast a powerful, skunky aroma with sweet and earthy undertones. The high is perfectly balanced: a clear, euphoric head rush that gently melts into a relaxing body stone, ideal for unwinding in the evening without locking you to the couch. Maintenance is minimal—just clean your tools and store your seeds in a cool, dark place for your next legendary grow.

How to Grow Skunk XL Seeds

Skunk XL is a low-difficulty, high-reward strain perfect for a wide range of growers.

Quick overview

Feminized photoperiod from Royal Queen Seeds. 55–60 day flower. Ideal for indoor SOG/SCROG or outdoor in warm climates.

• Germinate seeds on moist paper towel in darkness
• Transplant to final pot (11–20 L) when 2–3 nodes appear
• Use a well-draining soil or coco coir mix
• Start with a 18/6 light cycle for vegetative growth

Directed growth

Guide your plant for maximum light exposure and yield.

• Apply low-stress training (LST) early to create a flat canopy
• Water when the top inch of soil feels dry
• Feed with a balanced veg nutrient like Pro Organic Grow ( BioThrive Grow )
• Ensure strong airflow to prevent pests and build stem strength

Transition to flowering

Flip the light cycle to trigger bud production.

• Switch to a 12/12 light schedule to initiate flowering
• Expect a slight stretch in the first 1–2 weeks
• Begin a bloom-specific nutrient regimen
• Monitor for pre-flowers to confirm sex (all should be female)

Flowering by stages

Optimize conditions for dense, resinous buds.

• Lower humidity to 40–50% to prevent bud rot
• Use a support net or trellis for heavy colas
• Apply a PK booster in weeks 4–6 for increased density
• At the end of flowering, Flawless Finish Advanced Nutrients helps with a cleaner taste and smooth smoke

Harvest, drying and curing

Finish strong for the best possible smoke.

• Harvest when 70% of trichomes are milky, 30% amber for a balanced high
• Flush plants with plain water for 7–10 days before harvest
• Dry buds slowly at 18–22 °C (64.4–71.6 °F) and 50–60% RH
• Cure in airtight jars for 2–4 weeks, burping daily

Personal Experience of Pevgrow’s CEO (Alan)

Skunk XL is a staple in my personal grow room, and for good reason. I’ve grown it both indoors under a 600W HPS and outdoors in my Mediterranean garden, and it’s never let me down. Indoors, I use a 15 L pot and a SCROG net, which transforms it into a sea of bud sites. I start LST early, bending the main cola down to encourage lateral growth. It’s a feeder, so I pay close attention to my nutrient schedule—when it starts yellowing the lower leaves, I know it’s time to feed. Outdoors, it’s a monster, easily hitting 1.80 m (5.91 ft) and producing over 600 grams. The flavor is exactly what you want from a Skunk: pungent, sweet, and deeply satisfying. The high is perfectly balanced, making it my go-to for a relaxed evening. My only tip? Don’t rush the flush. Give it a solid 10 days, and you’ll be rewarded with a smooth, clean smoke every time.
