Apple Tartz strain guide: Everything you need to know about this sour-dough masterpiece from the innovators at Clearwater Genetics.

In this complete clone grow guide, we’ll break down its heavyweight lineage, complex tart-dough flavor profile, growth habits, and ideal companion strains. If you are looking for bag appeal that stacks heavy and smells like sour green apples dipped in petrol, Apple Tartz is the cut your garden is missing.

What our team says about growing Apple Tartz

Here's what I've learned running Apple Tartz in the rotation:

She brings the structure of the Fritter with the nose of the Runtz. If you are used to finicky exotics, you'll appreciate how robust she is—her stems are thick, but she will stretch significantly in the first 21 days of flower.

She is a heavy feeder compared to pure candy cuts; don't be afraid to push the EC slightly in weeks 4 through 6. Magnesium supplementation is key early on, as those broad leaves will stripe if you starve her.

Canopy management is crucial. Because of the Fritter lineage, she likes to go vertical. Top her multiple times in veg and use a double trellis to spread that canopy out horizontally.

The fade is legendary. Without even dropping temps drastically, you'll see deep burgundies and near-black hues wash over the fan leaves, making the neon green buds pop.

Harvest window is a solid 63 days for peak ripeness. Don't pull early; the "dough" terpene really develops in those final 5 days.

Apple Tartz = Runtz × Apple Fritter — a lineage that screams modern hype with old-school power. By combining the sugary, chemical-candy notes of Runtz with the earthy, bakery-rich density of Apple Fritter, Clearwater Genetics created a cultivar that checks every box. It's not just about the name; this strain delivers a unique sour-tart profile that cuts through the noise of generic poly-hybrids.

Apple Tartz Strain Terpene Profile

• Caryophyllene – Brings that spicy, bakery dough funk from the Fritter side.
• Limonene – Responsible for the sharp citrus and sour apple skin top notes.
• Linalool – Adds a soft floral complexity that smooths out the gas.
• Humulene – Provides the earthy base that grounds the sugary sweetness.

Overall aroma: Imagine opening a box of apple turnovers inside a gas station. It’s creamy, distinctly sour, and has a sharp chemical finish. It doesn't just smell sweet; it smells like fermentation and pastry dough.

Apple Tartz Grow Tips

• Stretch: High (expect 1.5×–2×). Plan your vertical space accordingly.
• Flower Time: 60–65 days.
• Yield: High; the Apple Fritter parentage adds significant bulk to the Runtz structure.
• Bud Structure: Dense, golf-ball style nugs that are incredibly difficult to squeeze.
• Feeding: Can handle a heavier regimen. Keep calcium and magnesium available through mid-flower.

Pro tip: Defoliation is your friend here. Because the leaves get massive (dinner-plate size), you need to strip the interior heavily on day 21 and day 42 to ensure light hits the lower sites. Keep airflow moving, as these dense colas can be prone to sweating if the environment is stagnant.

Apple Tartz Appearance: Bag Appeal & Bud Traits

Apple Tartz is a visual stunner that commands top dollar. The flowers are a dramatic mix of forest greens and royal purples, encased in a resin coat that looks like it was applied with a spray gun. The calyxes swell significantly late in flower, giving the buds a knobby, exotic look. If you grow for bag appeal, the contrast between the dark foliage and the white trichomes is unmatched.

Apple Tartz Rosin Behavior

• Wash yield (fresh frozen): 3.5–4.5%.
• Rosin return: Greasy, terpene-rich extracts.
• Press temp: 170–180°F (go lower to preserve the volatile fruit esters).
• Best texture: Wet badder or cold-cure batter.

While some Runtz crosses don't wash well, the Fritter genetics add trichome stability. The heads are oily and melt down into a golden-yellow hue. The flavor translates beautifully, often tasting more like a sour apple candy in concentrate form.

Best Clones to Pair With Apple Tartz

• Purple Diesel strain – If you want to keep the purple theme going with added fuel.

Our notes from smoking Apple Tartz

Apple Tartz is the definition of "all-day fire." The smoke is thick and creamy, expanding in the lungs with a tart apple exhale that lingers on the palate. The high is hybrid perfection—it starts right behind the eyes with a euphoric buzz that makes music sound better and food taste amazing. About 45 minutes in, the Fritter heaviness creeps into the shoulders. It’s not a knockout punch, but it’s heavy enough to make you want to sit down and chill. I love this strain for a Saturday afternoon BBQ or a creative session where you need focus without the jittery energy.

Final Thoughts: Why Apple Tartz Stands Out in 2026

Apple Tartz by Clearwater Genetics isn't just another Runtz cross; it's a perfect example of hybrid vigor. It takes the weak stems out of Runtz and adds the yield of Fritter, without sacrificing that elite flavor profile. It offers a complex bouquet of sour dough and fruit that is instantly recognizable, combined with a growth structure that rewards the commercial grower.
