Lemon Citron Feminized Seeds – Humboldt Seeds’ Citrus OG Powerhouse

Lemon Citron feminized seeds from Humboldt Seeds are your express ticket to cultivating a legendary West Coast citrus OG experience, combining explosive flavor with a deeply satisfying, balanced high.

Ever feel like you're chasing that perfect, classic lemon-fueled high but end up with plants that are either too finicky or don't deliver on the yield? You invest weeks into a grow, only to be disappointed by weak aromas or a lackluster harvest. That frustration of missing out on that iconic, gassy-citrus punch is real.

Lemon Citron solves this by merging the legendary, pungent Sour Diesel x Lemon Skunk cross (Lemon Tree) with Humboldt's elite, citric-leaning OG. The result is a vigorous, fast-growing plant that's built for production. Its thin fan leaves allow for excellent light penetration, leading to long, stacking colas that develop into substantial, resin-drenched bud sites. This isn't a shy plant; it's bred to perform.

What to Expect Your First Grow

Your first run with Lemon Citron will show you its aggressive nature. It's a fast, grateful plant that responds well to care. You'll notice vigorous growth from the start, with strong lateral branching that sets the stage for a heavy harvest. During the stretch in early flower, be prepared—it can more than double in height, so plan your space accordingly. The real reward comes as the terpenes develop, filling your space with an unmistakable blend of sharp lemon peel, spicy pine, and a gassy OG undertone.

Common Mistakes and How to Avoid Them

• Underestimating the Stretch: This plant can get tall. Use low-stress training (LST) early or employ a SCROG net to manage height and maximize your canopy.
• Underfeeding: Its high metabolic demand means it's a hungry plant. Stick to a robust feeding schedule, especially during peak flowering.
• Poor Airflow: Dense buds need good circulation. Ensure strong ventilation and consider defoliating some inner fan leaves to prevent moisture buildup and allow light to reach lower sites.
• Harvesting Too Early: Patience pays. Let the buds fully mature and the trichomes cloud up for the full spectrum of effects and flavor.
• Ignoring Support: Those long, heavy colas will need it. Use stakes or trellising, especially for outdoor monsters that can reach over 4 meters (13.12 ft).

How to Dial in Your Perfect Sweet Spot

1. Start Simple: Get your environment right first—stable temperatures (22-26°C in veg, 20-25°C in flower) and pH (6.0-6.5 for soil).
2. Observe the Stretch: In the first 2-3 weeks of flower, note how much it grows. This tells you how much headroom you'll need next time.
3. Feed for Vigor: This plant can handle and needs strong nutrients. Increase feed strength gradually as it enters flowering.
4. Train for Light: Gently bend and tie branches during veg to create an even canopy. This ensures all bud sites get direct light.
5. Monitor Trichomes: For a more energetic high, harvest when trichomes are mostly milky. For a heavier, more relaxing effect, wait for some amber to appear.
6. Dry and Cure Slowly: Don't rush the finish. A slow dry (60% RH, 18-20°C) followed by a 4-week cure in jars will dramatically enhance the final flavor and smoothness of the smoke.

Frequently Asked Questions

How long does it take from seed to harvest?

For indoor growers, plan for approximately 8-10 weeks of flowering after a 4-6 week vegetative period, so roughly 12-16 weeks total. Outdoors in the Northern Hemisphere, seeds planted in spring will be ready for harvest around mid-October.

Is Lemon Citron suitable for beginners?

Its vigor and resistance make it forgiving, but its high nutrient demand and need for training/support place it at a medium difficulty level. A beginner with good research can succeed, but it's ideal for growers with some experience.

What's the best way to maximize the lemon flavor?

Stress the plant slightly during the final weeks (slight underwatering can help), ensure a proper flush before harvest, and most importantly, do a slow, proper dry and cure. The terpenes develop fully during the cure. Using terpene-enhancing supplements during flowering can also help bring out the citrus notes.

How do I manage its height indoors?

Employ Low-Stress Training (LST) during the vegetative stage to keep the canopy even and low. Switching to a 12/12 light cycle earlier will also limit the stretch. A SCROG net is highly recommended to support the heavy colas and maximize light exposure to all bud sites.

Personal Experience of Pevgrow’s CEO (Alan)

Lemon Citron is one of those strains that reminds you why you got into growing. The first thing that hits you is the smell—it's like walking into a garage where someone is zesting lemons over a diesel engine. Unforgettable. I ran her in a mix of coco and perlite, and her hunger was real; she wanted strong feeds, especially during the peak flower weeks. I used a two-layer trellis, which was absolutely necessary—those colas get long and heavy. The yield was insane for the space. The high is its best feature: it clears your head and melts away tension without ever making you feel stuck. It's my go-to for a productive, creative afternoon. The only tip I'd give is don't be shy with the nutrients, and definitely don't skip on the support. She rewards the effort with some of the most flavorful, potent buds you'll grow.
