Apple Tartz

Also known as: Apple Tarts, Apple Tart

Breeder: Clearwater Genetics

Lineage & Genetics

Cross: Apple Fritter x Runtz

Apple Fritter (Sour Apple x Animal Cookies) was created by Lumpy's Flowers in Northern California circa 2013 and is known for its dense, frosty structure, pastry-sweet aroma, and heavy potency. Runtz (Zkittlez x Gelato), popularized by the Runtz Crew and Cookies, contributes rainbow-candy aromatics, creamy gelato texture, and exceptional resin coverage. Apple Tartz inherits Fritter's sturdy, vigorous plant structure and doughy base notes while layering in Runtz's bright fruit-candy top notes and trichome density.

Terpene Profile

Aroma: Tart green apple and sour candy hit first, followed by a creamy dough and pastry-sweet middle. Undertones of cinnamon spice, dark berry, and a gassy fuel finish emerge as buds are broken open. Multiple reviewers compare the nose to Apple Jacks cereal or cookie dough straight from the oven.

Flavor: Sour apple on the inhale transitions into creamy berry-gas with a buttery pastry sweetness. The exhale carries cinnamon spice, earthy cookie undertones, and a faint diesel tail. The flavor complexity is a direct expression of its high terpene totals (1.5–2.8%), and batches testing high in limonene and caryophyllene deliver the most pronounced profile.

Effects & Experience

Onset: Fast-acting — usually 1–2 hits produce a warm cerebral euphoria described as 'a warm light being turned on in a dim room.' Mood lifts noticeably within the first few minutes.

A tingly, buzzy head high clears mental fog and elevates mood, often making users chatty and giggly. Over 20–40 minutes, a warm, relaxing body buzz settles in without heavy sedation or couch-lock. The balance keeps you functional — suitable for social settings, creative work, or unwinding without immediately needing to sleep.

Duration: 2–3 hours typical; body relaxation may linger longer at higher doses.

Growing Characteristics

Grow Tips: Breeder notes: triggers into flower quickly with minimal stretch — plant density can be increased ~33% for row cropping or SOG setups. Strong lateral branching from Apple Fritter parent responds extremely well to LST, topping, and SCROG. Open the canopy early in veg for maximum bud-site development. Medium-to-heavy feeder; bump phosphorus in weeks 4–7 of flower for bud density and resin. Keep EC 1.8–2.2 during peak bloom. Dense, resinous colas are mold-susceptible — defoliate interior fan leaves around week 5–6 of flower and keep RH below 50% in late flower. Needs very little trellis support per breeder; sturdy, vigorous structure from the Fritter side. Late-cycle flush (final 10–14 days) helps express the full limonene-forward terpene profile. WASH DATA: Fresh-frozen extraction yields 4–5% finished live rosin per breeder (Cannabis Business Times). Wash at 0–4°C, press at 80–90°C for 60–120 seconds to balance yield and terp retention. Total terpene loads of 1.5–2.8% in flower translate to proportionally higher terp content in concentrates.

History & Origin

Clearwater Genetics, a boutique breeder collective based in Colorado Springs, developed Apple Tartz as part of their Apple Fritter feminized seed line. Breeder Alex Wullbrandt has called it the 'best-selling, most sought-after cross' in that line. The strain rose to prominence in 2022 when Leafly named it Strain of Summer 2022, cementing its reputation on dispensary menus across legal markets. Clearwater later collaborated with grower Jollygreenthumb on a refined Apple Tartz selection that 'took it up a notch,' and crossed it with Dante's Inferno to push the line further. Despite Clearwater's low-key profile, Apple Tartz has been widely adopted by licensed producers nationwide.
