Super Lemon Haze x GMO Feminized Seeds · Green House Seeds · 30% THC Sativa-Dominant Hybrid

Super Lemon Haze x GMO feminized seeds from Green House Seeds represent the ultimate fusion of legendary genetics, merging the award-winning citrus punch of Super Lemon Haze with the intensely resinous, funky power of GMO. This isn't just another hybrid; it's a 30% THC sativa-dominant beast engineered for growers who chase extreme flavor profiles and hash-making potential. Imagine dense, trichome-caked buds that smell like a gourmet kitchen experiment gone wonderfully right—zesty lemon peel colliding with deep, earthy notes of garlic, onion, and forest floor. The result is a plant that delivers a soaring, creative head high before melting into a satisfyingly heavy body stone, making it a perfect daytime adventure that doesn't leave you completely couch-locked.

Struggling to Find a Strain That's Both a Flavor Bomb and a Potency Powerhouse?

You know the drill. You browse through endless seed catalogs, looking for something that truly stands out—not just another "lemon" or "kush" variant. You want a strain that makes your friends do a double-take when they smell it, one that produces enough resin to make extraction a dream, and delivers an effect that's both uplifting and profoundly satisfying. But too often, high-THC claims come with bland flavors, or amazing terpene profiles lack the knockout punch. It's frustrating to invest months into a grow only to end up with something... forgettable.

The Consequence of Settling for Less

Settling for generic genetics means wasting your time, nutrients, and energy on a harvest that doesn't excite you. You're left with buds that might get you high, but don't tell a story. The smoke is unremarkable, the bag appeal is mediocre, and you're already planning the next grow before this one's even cured. For hash makers, weak resin production means low yields and a less potent final product. You deserve a grow that's a conversation starter, a jar that empties first at every session, and a plant that rewards your effort with something truly exceptional.

Your Search Ends Here: The Ultimate Sativa Hybrid Experience

Green House Seeds solved this problem by creating Super Lemon Haze x GMO. They took the iconic, energy-boosting Super Lemon Haze—a multiple Cannabis Cup winner—and crossed it with the infamous GMO, renowned for its insane resin output and unique funky terpenes. This cross guarantees you won't get a boring harvest. You're cultivating a piece of cannabis history, a strain designed for the discerning grower who values both effect and artistry. This is your ticket to growing buds that are as memorable to smoke as they are impressive to look at.

Phase 1: Laying the Foundation for a Monster

Your success starts with a perfect beginning. This vigorous plant needs a strong foundation to support its potential massive size and heavy yields.

• Germination is Key: Soak seeds in water at 22–25°C (71.6–77°F) for 24 hours until a taproot appears. For a stress-free start that promotes explosive root development, consider using a Seedbox Plagron germination kit.
• Right Home from the Start: Plant directly into a light, airy substrate. For photoperiods like this, a final pot of 11–20 L (2.9–5.3 gal) is ideal, depending on your space.
• Environment Matters: Maintain 60–70% humidity and temperatures of 22–26°C (71.6–78.8°F) during the seedling stage.

Phase 2: Vegging for Structure and Strength

This is where you build the framework for those huge colas. Super Lemon Haze x GMO exhibits strong, stretchy sativa growth that needs management.

1. Light Cycle: Run an 18/6 light schedule. Provide strong, full-spectrum lighting to encourage tight node spacing.
2. Training is Highly Recommended: This plant benefits greatly from Low-Stress Training (LST) to control height and create an even canopy. Topping above the 5th node is also effective for maximizing yield.
3. Feed for Vigor: Begin with a light nutrient regimen focused on nitrogen. Keep pH between 6.0–6.5 for soil. The plant is vigorous but avoid overfeeding early on.

Phase 3: The Flowering Power Show

Get ready for the main event. The stretch is real, and the bud production is spectacular.

1. The Switch: Flip to a 12/12 light schedule to induce flowering. Expect a significant stretch, so ensure your light has room to move.
2. Environment Tweaks: Lower humidity to 40–50% to prevent mold in the dense buds. Maintain temperatures around 20–25°C (68–77°F).
3. Nutrient Shift: Transition to a bloom-focused nutrient formula higher in phosphorus and potassium. Many growers report excellent results with the Green House Feeding line, designed for these genetics.
4. Support is Non-Negotiable: The heavy, resinous buds will need support. Use stakes, yo-yos, or a SCROG net to prevent branches from snapping.
5. Patience Pays: This is a 10–11 week flowerer. Don't rush it. Watch the trichomes develop from clear to milky and finally to amber for your desired effect.

Phase 4: Harvest, Dry, and Savor the Victory

Your patience is about to be rewarded with a legendary harvest.

When most trichomes are milky with 10-20% amber, it's time to chop. Flush the plants with plain water for 7-10 days prior to harvest for a cleaner taste. Dry slowly in a dark room at 18–22°C (64.4–71.6°F) and 50–60% humidity for 10-14 days. For the final touch that enhances flavor and smoothness, a proper cure of 2-4 weeks in airtight jars is essential. This process transforms good bud into great bud.

Why This Structured Approach Beats Wingin' It

Following a clear plan with Super Lemon Haze x GMO isn't just about avoiding mistakes; it's about unlocking its full, mind-blowing potential.

• Maximized Yield: Proper training and feeding turn its vigorous growth into structured, light-receiving colas, leading to indoor yields of 550+ g/m² (1.77+ oz/ft²) and outdoor monsters up to 1.8 kg (3.97 lb) per plant.
• Controlled Power: Managing the stretch prevents a jungle in your tent and ensures even bud development top to bottom.
• Flavor Preservation: Correct drying and curing lock in that insane citrus-garlic terpene profile, so your smoke tastes as wild as it smells.
• Hash Maker's Dream: The extreme resin production means more material for extracts like bubble hash or rosin, maximizing the return on your growing effort.
• Confidence from Start to Finish: Knowing what to expect each week removes the guesswork and lets you focus on enjoying the grow.

Frequently Asked Questions

Is Super Lemon Haze x GMO good for beginners?

It's rated as medium difficulty. While vigorous, its long flowering time (10-11 weeks) and need for support and environment control make it better suited for growers with some experience who can be patient.

How tall does it get?

Indoors, height is variable and can be managed with training. Outdoors, it can reach 1.50–2.30 m (4.92–7.55 ft), so plan your space accordingly.

What does it smell like while growing?

The aroma is strong and complex—a pungent mix of sharp lemon zest and funky, earthy GMO notes (garlic, mushroom, onion). A carbon filter is highly recommended, especially late in flower.

When is it ready to harvest outdoors?

In the Northern Hemisphere, expect harvest by the end of October. In the Southern Hemisphere, aim for the end of April.

Is it resistant to mold and pests?

It shows good vigor, but the dense buds are susceptible to botrytis (bud rot) in high humidity. Maintain good airflow and keep humidity in check during the final weeks.

Personal Experience of Pevgrow’s CEO (Alan)

Let me be straight with you: Super Lemon Haze x GMO is not a "set it and forget it" plant. It demands attention, but man, does it pay you back. The first thing you notice is the stretch—it's a sativa beast that wants to reach for the sky. I learned quickly that a SCROG net or some serious LST is non-negotiable unless you have ceiling height to spare. My advice? Top it early and train those branches horizontally. You'll thank me when you see an even canopy of fat, dripping colas instead of one towering main cola and a bunch of larf below.

The real magic happens around week 6 of flower. The smell transforms from generic green to this insane funk that fills the room. It's like someone is zesting lemons next to a sauté pan of garlic mushrooms. You absolutely need a good carbon filter. I pushed mine to 11 weeks, and the resin production was obscene—the buds were literally sticky to the touch, perfect for making bubble hash. The high is exactly as advertised: a clear-headed, creative rush that slowly melts into a heavy, satisfying stone. It's a daytime strain for me, but one that definitely tells you when it's time to chill. Just be patient, support those branches, and control the humidity in the final weeks. The wait is 100% worth it for this one-of-a-kind smoke.
