Serious Happiness Feminized Seeds by Serious Seeds – High-Yielding Sativa/Indica Hybrid for Easy Growing & Potent Effects

Serious Happiness feminized seeds by Serious Seeds deliver a powerful sativa/indica hybrid that grows easily and rewards you with dense, resinous buds and a long-lasting euphoric buzz — perfect for turning good days into great ones.

Struggling with finicky plants and underwhelming highs?

Let’s be real: not every strain lives up to the hype. You spend weeks nurturing a plant, only to end up with weak yields, inconsistent effects, or a flavor that’s more ‘meh’ than magical. And if you're growing indoors, poor structure or leafy buds can turn trimming into a nightmare.

What if your plant stretched your patience — and your space?

Some strains grow wild, stretch too much, or demand constant attention. You’re left battling humidity, topping like crazy, or dealing with airy buds that barely spark joy. And when harvest finally comes, the high might knock you out — or do nothing at all. That uncertainty kills the vibe before you even light up.

Serious Happiness fixes that — fast, stable, and seriously rewarding

This hybrid, born from legendary AK-47 and Warlock, grows with near-perfect structure: strong stems, even branching, and fat colas that practically manicure themselves. You get big yields without the stress, sweet fruity flavors that linger, and a balanced high that lifts your mood without locking you to the couch. It’s happiness, grown right.

Compact structure, massive returns

Serious Happiness strikes the ideal balance between sativa vigor and indica compactness. Indoors, it reaches 0.80–1.10 m (2.62–3.61 ft), making it perfect for SCROG or SOG setups without sacrificing yield. Outdoors, it handles moisture and pests like a pro, thriving in Mediterranean or temperate climates. Its wide internodal spacing improves airflow, reducing mold risk — especially when you pair it with proper ventilation from our hemp-based air filters.

Precise control for consistent results

• Flowers in a reliable 60–70 days — no guessing games
• Responds well to LST and light topping for maximum canopy control
• Stable genetics mean uniform growth — no weak links in your grow
• High calyx-to-leaf ratio ensures dense, easy-to-trim buds
• Thrives on standard feeding — no complex nutrient schedules needed
• Consistent THC expression for predictable, uplifting effects

How to grow Serious Happiness for best results

Start strong and keep momentum with smart, simple steps.

1. Germinate seeds in a moist paper towel or starter cube at 22–25 °C (71.6–77 °F)
2. Transplant to 11–20 L pots when roots emerge — use well-aerated soil or coco
3. Keep light cycle at 18/6 during veg, then switch to 12/12 to trigger flowering
4. Monitor pH at 6.0–6.5 (soil) or 5.8–6.2 (coco/hydro) for optimal nutrient uptake
5. Support heavy colas with soft ties during mid-flowering to prevent breakage
6. Harvest when trichomes turn milky to amber for a balanced, euphoric effect

Advice on how to grow the seed

Maximize yield and flavor with a simple, proven approach.

Quick overview: Feminized hybrid from Serious Seeds — 60–70 day flowering, low-moderate difficulty, ideal for indoor and outdoor grows in temperate climates.

Safe start: Germinate with care for strong seedlings.

• Use a moist paper towel or starter plug at 22–25 °C (71.6–77 °F)
• Transplant when the taproot is ~1 cm (0.39 in) long
• Choose a light, well-draining mix to prevent damping off
• Consider PEV Seeds for backup genetics

Directed growth: Shape early for maximum yield.

• Use 18/6 light cycle in veg for steady development
• Apply light topping or LST in week 2–3 to boost side branching
• Pot directly into 11–20 L containers to minimize stress
• Ensure good airflow to strengthen stems and reduce mold risk
• Feed with balanced nutrients — avoid excess nitrogen

Flowering by stages: Support and nourish through bloom.

• Switch to 12/12 to initiate flowering — expect stretch in first 2 weeks
• Lower humidity to 40–50% to protect dense buds
• Use soft ties or trellis to support heavy colas
• Boost with bloom stimulants like Barney's Farm additives

Harvest, drying and curing: Finish strong for premium quality.

• Harvest when 70% of trichomes are milky, 30% amber for balanced effect
• Flush 7–10 days before harvest to improve taste
• Dry at 18–22 °C (64.4–71.6 °F) and 50–60% RH for 7–10 days
• Cure in jars for 2–4 weeks, burping daily to prevent mold

Personal Experience of Pevgrow’s CEO (Alan)

I grew Serious Happiness last season in my 1.2 m² tent with 600W HPS, and it was one of the smoothest grows I’ve had. I did a light topping at 15 cm (5.9 in) and used LST to spread the canopy. By week 3 of flowering, it was a jungle of colas — no weak spots, no hermies. The smell during week 6 was unreal: sweet berries with a diesel kick. I harvested at 63 days, dried slowly, and cured for three weeks. The high? Instant smile, clear head, relaxed body — exactly what I need after a long day. I’ve shared clones with friends, and every single one said the same: 'This one’s a keeper.'
