AlienZ Feminized Seeds – Watermelon Zkittlez x Velvet Moon Genetics, 24.3% THC

AlienZ feminized seeds from Green House Seeds are your ticket to cultivating a powerhouse hybrid that delivers a euphoric, giggly high and an unforgettable explosion of candy sweetness and zesty lemon flavors. This is the strain that turns a good day into a great one and a stressful one into a distant memory.

Ever feel like your grow space is missing that one standout plant—the one that looks as incredible as it smokes, packing both monstrous yields and boutique-quality resin? You plant the seed, nurture it for weeks, only to end up with a harvest that's just... fine. It's frustrating when the final product doesn't match the effort, leaving you with decent bud but nothing that truly wows you or your friends. AlienZ solves this by combining the vigorous structure and heavy resin production of elite genetics into a single, reliable seed.

Phase 1: Laying the Foundation for a Monster

Before you even germinate, setting the stage is crucial. AlienZ is a robust plant, but it rewards a thoughtful start. Begin with a high-quality, well-aerated substrate to support its strong root development. A simple yet effective product like Terra HY-PRO provides the perfect balance of drainage and nutrient retention. Ensure your environment is stable—aim for a temperature of 22–26 °C (71.6–78.8 °F) and high humidity (70–80%) for the seedling stage.

• Check your equipment: Ensure your grow light is adequate for a plant that can stretch.
• Prepare your space: AlienZ can reach 1.20–1.80 m (3.94–5.91 ft) indoors, so plan vertical space.
• Choose the right pot: Start in a small pot and transplant to a final container of 11–20 L (2.9–5.3 gal) for optimal root freedom.
• Germinate with care: Use the paper towel method in a warm, dark place (22–25 °C / 71.6–77 °F).

Phase 2: Vegetative Vigor and Training

Once your seedling has established, AlienZ's genetics from the Green House Seeds stable will show their strength. This phase is about building the framework for those massive colas.

1. Transplant carefully when the seedling has 3–4 sets of true leaves into its final pot.
2. Maintain an 18/6 light cycle and watch the plant develop a strong, central stem with long secondary branches.
3. Begin low-stress training (LST) early to open up the canopy and expose more bud sites.
4. Feed a balanced, nitrogen-rich diet to support its rapid vegetative growth.
5. Keep humidity around 50–60% and temperatures steady.

Phase 3: The Flowering Powerhouse

Switch your lights to a 12/12 cycle to initiate flowering. Over the next 8–9 weeks, AlienZ will transform, stacking dense, resinous flowers on every branch. The smell intensifies into a pungent mix of sweet watermelon and sharp lemon—a carbon filter is highly recommended.

1. Early Flower (Weeks 1-3): The stretch is real. Support branches if needed. Reduce nitrogen and introduce more phosphorus and potassium.
2. Mid Flower (Weeks 4-6): Colas fatten up dramatically. Resin production goes into overdrive. Consider adding a bloom booster like Big Bud Powder to enhance density and trichome development.
3. Late Flower (Weeks 7-9): Trichomes turn milky white. Flush with plain, pH-balanced water for the final 10–14 days. Lower humidity to 40–50% to prevent mold.
4. Watch for maturity: Harvest when most trichomes are milky with 10–30% amber for a balanced, long-lasting effect.

Phase 4: Harvest, Dry, and Savor the Rewards

Your patience pays off. Harvest those glittering, sticky buds, dry them slowly in a dark room at 18–22 °C (64.4–71.6 °F) and 50–60% RH for 10–14 days, then cure in jars for a minimum of 2–4 weeks. This process locks in the complex sour candy and earthy terpene profile.

• Dry slowly: Preserve terpenes and ensure a smooth smoke.
• Cure properly: Burp jars daily for the first week to perfect flavor and potency.
• Store correctly: Keep in a cool, dark place in airtight containers.

Personal Experience of Pevgrow’s CEO (Alan)

Let me tell you, AlienZ is a grower's dream and a smoker's delight. I ran her in a 1.2x1.2 m (4x4 ft) tent under LED, and her vigor from the Velvet Moon side was immediately apparent—she shot up during the stretch. I used mild LST to tame those long branches, and it paid off with multiple, equally massive colas instead of just one main one. The smell around week 6 of flower is insane; it's like a candy shop exploded next to a lemon grove. You absolutely need a carbon filter. I pushed her with nutrients but found she's quite resilient, not too fussy. The harvest was staggering—dense, rock-hard buds coated in sticky resin that made trimming a lengthy but happy chore. The smoke? Unreal. It hits with a cerebral buzz that makes everything funny, then melts into a deep, satisfying body relaxation without locking you to the couch. It's my go-to for weekend sessions with friends. Just watch your ceiling height and keep that airflow high during late flower, and she'll reward you big time.
