Lemon Mandarin 420 Fast Buds Feminized Seeds – High THC Citrus Hybrid for Massive Yields

Lemon Mandarin 420 Fast Buds is your gateway to a high-octane citrus explosion—this feminized hybrid delivers sky-high THC, outrageous yields, and a flavor profile that hits like a fresh-squeezed mandarin sunrise.

Are you still settling for bland, underwhelming harvests?

Maybe your current strain lacks that punch—the kind of vibrant, mouthwatering aroma that sticks to your clothes and fills the room before you even light up. Or perhaps you’re tired of finicky plants that snap under their own weight or collapse when you try to train them. You want something bold, resilient, and packed with personality—but without the headache.

What if your next grow could be bigger, louder, and more rewarding than ever?

Imagine walking into your grow room and being hit with a wave of zesty lemon and sweet mandarin—no air freshener needed. Picture buds so resinous they glitter under the lights, stretching skyward with thick, sturdy branches that laugh off stress. Now imagine harvesting up to 600 g/m² indoors or a jaw-dropping 1.2 kg per plant outdoors, all from a strain that bounces back from topping and thrives under SCROG. That’s not a dream. That’s Lemon Mandarin.

• Requires good airflow due to dense foliage
• Use a carbon filter to manage strong citrus odor

Safe start

Launch your grow with strong germination and early vigor.

• Germinate seeds in moist paper towels at 22–25 °C
• Transplant carefully when radicle reaches ~1 cm
• Use airy, well-draining soil to prevent damping off
• Start Up Plagron boosts early root growth
• Keep humidity high (60–70%) in first week

Directed growth

Shape your plant for maximum light exposure and yield.

• Run 18/6 light cycle in veg
• Top or FIM at 4–6 nodes to increase branching
• Begin LST early to control height and spread
• Install SCROG net around week 3–4 of veg
• Defoliate lower leaves to improve airflow

Flowering by stages

Optimize conditions as your plant shifts into bud mode.

• Switch to 12/12 to trigger flowering
• Maintain 20–25 °C and 40–50% RH in flower
• Support heavy colas with stakes or netting
• Use bloom nutrients rich in PK and calcium
• Monitor trichomes: harvest at milky-amber for balanced effect

Harvest, drying and curing

Lock in flavor, potency, and smoothness with proper post-harvest.

• Flush plants 7–10 days before harvest
• Cut whole plant or branch-by-branch
• Dry at 18–22 °C and 50–60% RH for 7–10 days

Frequently Asked Questions

Is Lemon Mandarin good for beginners?

Yes—she’s resilient and forgiving, but benefits from training and airflow management. Great for growers ready to level up.

How many plants per square meter should I grow indoors?

Keep it to 2–3 plants/m² to allow space for her bushy structure and maximize light penetration.

Does this strain need a lot of nutrients?

She’s a heavy feeder, especially in flowering. Follow a quality nutrient line like Sensi Bloom A+B for best results.

Can I grow Lemon Mandarin outdoors in a colder climate?

She prefers heat and sun, but can handle moderate temps if protected from rain and frost. Harvest in early October (N. hemisphere) or early April (S. hemisphere).

Why is defoliation important for this strain?

She grows large fan leaves that can block light and trap humidity. Light defoliation improves airflow and bud development.

Personal Experience of Pevgrow’s CEO (Alan)

I grew Lemon Mandarin in my outdoor garden last season, and damn—she was a showstopper. Started her in a 15L pot, topped her twice, and ran a SCROG net. By week 6 of flower, she was 1.8 m tall and covered in sticky, citrus-scented colas. I harvested 1.1 kg off a single plant—dry, cured, and absolutely fire. The high was uplifting, clear-headed, perfect for morning sessions or creative work. The only thing I’d do differently? More aggressive defoliation earlier on. Those fan leaves get wild. If you love flavor, potency, and big yields, this one’s a must-grow.
