Rainbow Gas Feminized Seeds – Silent Seeds | Exotic 27-30% THC Hybrid

Rainbow Gas feminized seeds from Silent Seeds deliver a next-generation cannabis experience, combining elite Californian genetics with sky-high 27–30% THC levels and an unforgettable custard cream meets gassy Kush flavor. This limited-edition hybrid isn’t just powerful—it’s a masterpiece of stability and sensory depth, crafted for discerning growers and connoisseurs.

Overwhelmed by average strains?

Let’s face it: most so-called ‘exotic’ strains promise big but fizzle out—weak aromas, inconsistent phenos, or underwhelming effects. You want something that actually lives up to the hype, not another genetic letdown.

Why your current setup falls short

Generic hybrids often lack complexity—either too cerebral or too sedating, with flat terpene profiles that vanish after one puff. Without true genetic stability, you’re rolling the dice on every grow. And if you're chasing that rare combo of euphoria, flavor, and body melt, most strains just don’t cut it.

The collector’s choice: Rainbow Gas

Rainbow Gas fixes all that. Born from a meticulous cross of RS-11 and Animal Face Mints—descended from Wedding Cake and Zkittlez royalty—this feminized hybrid offers elite consistency, explosive terpenes, and a perfectly balanced high. It’s not just another strain. It’s a statement.

Elite genetics, unmatched stability

Rainbow Gas stands out thanks to its remarkably low phenotypic variation—a rarity among modern polyhybrids. When you grow these seeds, you’re not gambling. You’re cultivating uniform, robust plants with large, wide leaves and long internodes that welcome light and airflow. Indoors or out, this structure means fewer surprises and maximum bag appeal.

• Because it’s bred from elite clones of RS-11 and Animal Face Mints, you get exceptional genetic stability, which means you can expect consistent plant structure and potency across your entire grow.
• Thanks to its open, well-spaced branching, you achieve better light penetration and airflow, which reduces the risk of mold and helps you develop dense, resinous colas from top to bottom.
• With a flowering time of just 58–63 days indoors, you enjoy a fast turnaround without sacrificing quality—perfect for growers who value efficiency and excellence.

Explosive flavor and aroma profile

One whiff of Rainbow Gas and you’ll understand why it’s a terpene powerhouse. Think rich pastry cream, sweet candy floss, and a bold gassy Kush punch—all layered with complex floral and earthy undertones. This isn’t background noise; it’s a full-spectrum sensory experience that lingers long after the smoke clears.

• Thanks to its dominant terpenes—myrcene, caryophyllene, and limonene—you get a deeply aromatic profile that’s both sweet and spicy, making it ideal for extractions or pure sensory enjoyment.
• Because the aroma intensifies during late flowering, especially with a 10°C day-night temperature drop, you can boost its complexity and coloration for maximum visual and olfactory impact.
• With such a rich terpene expression, you experience enhanced flavor depth in every hit, turning your session into a gourmet cannabis experience.

Powerful, evolving effects for evening moments

Rainbow Gas starts with a clear-headed euphoria—creative, uplifting, and social—then smoothly transitions into full-body relaxation. With THC levels hitting 27–30%, this isn’t a strain for beginners. It’s for those who appreciate a gradual descent into deep calm, perfect for unwinding after dark or sinking into a favorite movie on a lazy Sunday.

• Because it delivers a hybrid mind-body effect, you stay mentally present while your muscles melt away tension—ideal for evening use when you want to relax without passing out.
• With such high THC content, you experience intense euphoria and sensory enhancement, making it a favorite among seasoned consumers seeking depth and duration.
• Thanks to its indica-dominant finish, you enjoy deep physical relaxation that may support restful sleep—perfect for nighttime rituals.

Abundant yields, resilient outdoors

Whether you’re growing indoors or under the sun, Rainbow Gas rewards effort with results. Indoors, expect 550–600 g/m² (19.4–21.2 oz/ft²) of dense, trichome-coated buds. Outdoors, plants reach 2.6–2.8 m (8.5–9.2 ft) and produce 1.5–1.8 kg (3.3–4.0 lb) per plant when harvested in late September to early October.

• Because it responds well to training techniques like SCROG, LST, and topping, you can maximize light exposure and boost yields without compromising plant health.
• Thanks to its resilience in temperate and Mediterranean climates, you can grow it outdoors with confidence, knowing it handles minor weather fluctuations and resists mold when airflow is maintained.
• With such high productivity, you get more harvest per plant, making it a cost-effective choice for long-term cultivation.

Get the most out of Rainbow Gas with a smart, phase-by-phase approach that maximizes flavor, yield, and stability.

Quick overview

Feminized photoperiod hybrid from Silent Seeds. 58–63 day flowering, medium difficulty. Ideal for indoor or outdoor grows in temperate climates.

Safe start

Launch your grow with strong germination and early root development.

• Germinate seeds at 22–25 °C with high humidity.
• Use a light, airy medium like Bio Thrive Grow to prevent damping off.
• Transplant once the taproot is 1 cm long.
• Keep lighting gentle—18/6 cycle from the start.
• For faster rooting, consider RootStimulator HY-PRO.

Directed growth

Build a strong, open structure ready for heavy flowering.

• Switch to 18/6 light cycle to promote vegetative growth.
• Use Jungle Juice Grow for balanced nutrition without stretch.
• Train early with LST or SCROG to shape the canopy.
• Top once to encourage multiple main colas.
• Maintain pH 6.0–6.5 in soil or 5.8–6.2 in coco.

Flowering by stages

Support dense bud development and terpene production.

• Switch to 12/12 to trigger flowering.
• Reduce humidity to 40–50% to prevent mold.
• Use B’Cuzz Blossom Builder in mid-flower for resin boost.
• Support heavy colas with stakes in the final weeks.
• Flush 7–10 days before harvest for cleaner taste.

Harvest, drying and curing

Lock in flavor and potency with proper post-harvest care.

• Harvest when trichomes are mostly milky with some amber.
• Cut branches and hang in a dark room at 18–22 °C.
• Dry slowly over 7–10 days at 50–60% RH.
• Cure in jars, burping daily for 2–4 weeks.
• Store in a cool, dark place for long-term preservation.

Frequently Asked Questions

Is Rainbow Gas suitable for beginner growers?

While it’s a medium-difficulty strain, its stability and resilience make it manageable for beginners who follow a solid feeding and training plan.

How can I enhance the terpene profile?

Lower nighttime temps by 10°C in the last two weeks and avoid overfeeding—especially nitrogen in late flowering.

Can I grow Rainbow Gas outdoors in a humid climate?

Yes, but ensure excellent airflow and consider using a natural fungicide like diatomaceous earth as a preventive measure.

Does it require a lot of nutrients?

No—it performs best with moderate feeding. Over-fertilizing can dull terpenes and stress the plant.

Personal Experience of Pevgrow’s CEO (Alan)

I’ve grown my fair share of exotic hybrids, but Rainbow Gas stands out. I grew it outdoors last season in a Mediterranean setup, and the uniformity blew me away—every plant looked like a clone. I used LST early to open up the canopy, then let it fly. By late September, the trichomes were thick, and the smell? Like a bakery mixed with diesel. I harvested 1.7 kg off one plant. After curing, the flavor was insane—sweet, gassy, complex. I shared it with friends who grow for a living, and they all asked where I got the seeds. If you want a strain that impresses even the skeptics, this is it. My only tip: don’t rush the dry. Let it hang a little longer—it’s worth it.
