Mephisto Genetics Description

High-Yielding, Frosted Autoflower with Citrus-Fuel Terps

If you’re chasing heavy resin production, rapid turnaround, and premium terp intensity, Icenberg from Mephisto Genetics deserves a place in your next run. This autoflowering hybrid combines top-shelf flavor, sticky trichomes, and 20–25% THC with a fast 9–11 week lifecycle—perfect for growers who want elite results without the long wait. With Mephisto’s limited drops and high demand, Icenberg rarely stays in stock for long.

Icenberg embodies Mephisto Genetics’ reputation for small-batch, high-performance autoflowers. Expect:

• 9–11 week seed-to-harvest timeline
• High yields with dense, frost-heavy colas
• 20–25% THC for strong yet balanced effects
• A citrus-sweet-fuel terp profile ideal for modern palates

This hybrid is well-suited for both advancing hobbyists and experienced growers who value consistency, potency, and terp richness. Its structure stays manageable, with fast veg growth and uniform lateral branching that makes canopy management straightforward.

Icenberg is crafted from two standout Mephisto staples:

• Sundae Thumper → sweet fruit-and-cream terps, chunky bud structure, dessert-style complexity
• Walter White BX1 → elite resin output, bright citrus edge, vigorous, uniform growth

This pairing was designed to deliver an autoflower with photoperiod-level bag appeal, extract-ready resin, and a predictable finish window. Expect:

• Strong germination
• Fast, confident growth rhythms
• Dense, crystal-covered buds with high terp retention

Icenberg is engineered for growers who want premium frost and flavor in a compact timeline.

Icenberg’s terpene profile blends zesty citrus, sweet fruit, and a subtle fuel finish, creating a layered, modern flavor experience. Key notes include:

• Candied lemon, orange zest
• Ripe fruit sweetness
• Light fuel edge on the exhale
• Piney uplift and peppered warmth

Dominant terpenes: limonene, myrcene, caryophyllene, pinene

The result is a mouth-coating, long-lasting flavor and a loud jar aroma straight out of cure. Its frost-heavy flowers give it exceptional bag appeal.

Icenberg offers a fast, euphoric onset that lifts mood, enhances focus, and promotes a creative headspace. Expect:

• Energizing, productive beginning
• Smooth transition into relaxed body ease
• A balanced hybrid arc with a clean comedown

Ideal for daytime use, creative projects, social sessions, and anyone seeking a feel-good hybrid with enough strength to satisfy connoisseurs.

Growers typically encounter three expressions:

1. Citrus-Cream Pheno
   • Lemon-lime nose
   • Taller posture
   • Tight, spear-like colas covered in frost
2. Fruity-Fuel Pheno
   • Louder fuel note
   • Chunkier golf-ball buds
   • Exceptional resin density for extraction
3. Balanced Hybrid Pheno
   • Even citrus/sweet ratio
   • Uniform internodes
   • Ideal for SOG runs and predictable performance

Across all phenos, trichome production is heavy, with some showing lavender hues in cooler conditions.

(General cultivation principles only.)

• Lifecycle: ~65–80 days (9–11 weeks)
• Skill Level: Beginner-friendly to intermediate
• Growth: Medium stature with strong lateral branching
• Training: Gentle LST preferred; avoid topping after early veg
• Feeding: Moderate; reduce nitrogen mid-cycle; cal-mag recommended under LEDs
• Lighting: Autos respond well to strong intensity (18–20 hrs/day)
• Yield:
  • Indoors: 450–550 g/m²
  • Outdoors: 80–150 g/plant in strong sun

Pro tips: Maintain stable VPD, avoid early overwatering, and support heavy colas near finish. A slow dry and careful cure preserve its citrus-fuel sharpness and terpene complexity.
