Strain Overview

Lineage and Breeding
Samsquanch OG imparts classic OG fuel, sturdy branching, and chunky flower sites, laying down the framework for dense, top-heavy colas. 4 Assed Monkey brings out loud citrus-sweet notes, rapid finishing, and a notorious trichome coat that looks sugar-dipped by week seven. Together, they form a hybrid that’s vigorous from the jump: fast to establish, eager to stack, and consistent across environments. The breeding goal is clear—deliver modern potency, terpy loudness, and auto convenience without sacrificing yield or structure. ILL#66 - Altered Beast does exactly that, with reliable internodal spacing, easy training response, and a resin flood that makes trimming a joy. Expect uniform performance with enough pheno diversity to keep connoisseurs engaged, and the kind of repeatable results that make this a set-and-forget tent champion.
Flavor and Aroma Profile
The first hit says “premium OG”—jet fuel and zesty citrus jump out, wrapped in earthy depth and a sweet exhale. Caryophyllene leads with peppery warmth, Myrcene rounds the body feel, Limonene sparks an uplifted mood, and Humulene adds that herbal, hoppy edge. The result is a layered flavor that lingers on the palate and fills the room fast. In the jar, ILL#66 - Altered Beast shines with sticky, crystal-laden buds and a terp cloud that screams top-shelf. Bag appeal is immediate: dense flowers, frost on frost, and aromas that cut through any lineup.
Effects and Benefits
Expect a quick, euphoric onset that brightens mood and loosens tension, followed by a steady relax that doesn’t couchlock. It’s a versatile day-to-evening companion—great for creative sessions, unwinding after work, or social hangs. The ride lasts comfortably with a gentle, clear comedown. With THC in the 21–25% range and CBD under 1%, ILL#66 - Altered Beast suits experienced users chasing potency and flavor, as well as newer enthusiasts who prefer a balanced hybrid feel without heavy crash.
Phenotypic Variation
Common expressions include:
- Fuel-forward OG pheno: taller, slightly more stretch, spear-shaped colas, loud gas and earth, massive frost.
- Citrus-sweet pheno: stockier with tighter nodes, rounder nuggets, brighter lemon-candy nose with sweet backend.
Both cut heavy and drip resin, but the gas-leaning pheno often runs a hair longer and may throw deeper greens and occasional purple hues in cooler temps. The citrus pheno cures quickly and pops loud in the jar. Pheno hunting is rewarding—select for your preferred terp balance and structure for future runs.
Growing Guide
Ideal for beginner-to-intermediate growers. Run 18–20 hours of light, 24–28°C day temps, and moderate humidity (65% seedling, 55% veg, 45–50% flower, 40% late). She loves gentle LST early; avoid heavy topping after week 3 to protect timelines. Expect 9–11 weeks seed to harvest, with high yields under dialed LEDs.
- Training: Early LST, leaf tucking, light defoliation around week 4–6 to open sites.
- Feeding: Moderate-heavy bloom nutrition; watch calcium/magnesium under strong LEDs.
- Yields: 100–200g per plant in large containers; 450–600g/m² in optimized SOG/SCROG.
- Pro tips: Keep airflow up—resin is thick. Support colas late. Consider a 48-hour dark finish to boost nose.
- Challenges: Can stack dense—manage RH and trim interior leaves to prevent microclimates.
