Grinch by Up The Hill

Grinch by Up The Hill

Grinch by Up The Hill is a true 50/50 balanced hybrid born from Mendodawg x Underdawg, two deep-rooted American dawg genetics colliding in a single cut. At 19-23% THC, this one sits in a comfortable sweet spot: citrus-forward on the nose, euphoric and creative on the onset, with enough body calm to keep everything smooth without pulling you under. A morning-to-daytime strain with a social, happy personality and low anxiety risk.

The Story

Up The Hill Creations is a Southern California breeding operation now based in Bangkok, carrying a catalogue of 21-plus strains that range from proprietary Z-family crosses to carefully selected heritage genetics. Grinch stands apart from the rest of the roster. Where most Up The Hill cuts lean into the Zkittlez-influenced candy-sweet wave, this one reaches back further into the American gene pool, pulling from two distinct branches of classic dawg-family cannabis.

The mother side is Mendodawg, a Gage Green Genetics creation that crosses a Chemdawg OG “Next Level” phenotype with the Mendo Montage Four Star male. That Mendo Montage traces back to Mendocino County stock: Mendo Purps females selected against a Crystal Locomotive male, carrying the dense resin production and purple-hued calyx structure that Mendocino genetics are known for. The father side is Underdawg, rooted in the Chemdawg family tree that produced both OG Kush and Sour Diesel. The original Underdawg cut came from a cross of ’91 Chemdog with a Mass Super Skunk and Sensi Northern Lights hybrid. Both parents trace their potency back to the same Chemdawg wellspring that defined American cannabis breeding for three decades.

What makes Grinch by Up The Hill interesting is the convergence. Two separate dawg lineages, one filtered through Mendocino mountain genetics and the other through East Coast chem stock, meeting in a balanced hybrid that inherited the citrus brightness and creative energy from the sativa side while keeping the earthy, resinous body character from the indica roots. The name fits the personality: slightly mischievous, surprisingly warm once you settle in.

The Nose

Crack the seal and Citrus hits first, bright and immediate, the kind of sharp lemon-forward note that fills a room before you break a single nug. Behind it, Fruity warmth expands the top end, giving the citrus a ripe, sun-warmed character rather than a thin acidic read. Sweet rounds out the mid-register, adding body and depth to the aromatic arrangement. Break the nugs apart and Earthy tones surface from the center, grounding everything with a raw, soil-forward undertone that speaks to the dawg genetics underneath the fruit. Berry appears last, a soft, rounded note that lingers when the jar sits open. Limonene drives the citrus pop in the top notes, pushing lemon zest brightness that makes the nose vivid and immediate. Pinene brings pine forest, fresh resin underneath, a clean, sharp character that lifts the earthy base and adds a coniferous edge to the exhale. Caryophyllene anchors the back end with a peppery kick, spicy wood that grounds the sweetness and prevents the profile from reading as one-dimensional. Linalool sits quietly underneath everything, adding floral, lavender softness that smooths the transitions between layers.

The Smoke

The flavor carries cleanly from jar to joint. Citrus and fruity coat the palate on the first pull, the Limonene translating directly into a bright, zesty hit that stays vivid on the inhale. The sweet base shows up on the exhale, giving each pull a fuller body than the nose alone would suggest. Midway through the session, earthy tones become more prominent as the Pinene opens up, adding that pine forest sharpness to the mid-joint experience while the berry note rounds out the transition. The Caryophyllene builds toward the last third, concentrating a peppery warmth in the resin ring that adds edge and complexity to the finish. The Linalool smooths the final pulls, keeping the smoke from turning harsh even as the terps concentrate. Clean ash, even burn, no harshness from start to roach.

The High

The onset is quick and the direction is upward. Euphoria arrives within the first minute or two, a genuine mood lift that brightens everything without pushing into racing territory. Creative builds right alongside it, the kind of lateral thinking headspace where ideas connect easily and conversation flows without effort. Energetic runs through the opening phase as well, a current of physical vitality that keeps you moving and engaged rather than rooted to one spot. The Limonene and Pinene combination contributes directly to this upward trajectory, two terpenes that work in tandem to brighten mood and sharpen mental clarity.

As the session progresses, Tingly sensations begin spreading through the limbs, a warm physical hum that signals the body side coming online. Happy reinforces the headspace, keeping the mood buoyant and social even as the physical effects deepen. Then Body Calm settles in, a gentle wave of ease that relaxes tension through the shoulders and back without dragging you toward the couch. The Linalool likely contributes to this soft landing, rounding the body effects into something comfortable rather than heavy. At moderate potency with low anxiety risk and medium sleepiness, the window stays functional and sociable for most of the ride, though you might notice a gentle pull toward rest as the Caryophyllene and Linalool concentrate in the later phase.

Effect group: Fun · Best time: Morning / Day
