Quick answers

Is Grape Ape indica or sativa?

An indica-leaning hybrid. The RQS seed line is listed as 90% indica and 10% sativa.3

How much THC does Grape Ape have?

18.42% median total THC in 202 flower tests; the middle half was 15.37%–21.25%. These are historical product labels, not genetic authentication.2

What does Grape Ape taste like?

Leafly readers most often report grape, berry and sweet flavors.1

Is every Grape Ape plant purple?

Purple coloration is a reported trait; RQS says it may develop late in flowering under cooler nights. It is not a way to authenticate a plant.4

Is Grape Ape indica or sativa?

Grape Ape is usually described as an indica-leaning hybrid. RQS gives its own version a 90% indica / 10% sativa split.3 Treat that as the breeder’s classification of its seed line, rather than a measurement of every product carrying the name.

Genetics: the three reported parent lines

Mendocino Purps, Skunk and Afghani are the parent lines listed by Leafly. RQS specifies Skunk #1 for its version.1,3 The family tree records those published relationships; our lab data does not establish parentage.

From Apothecary to later seed lines

RQS attributes the original to Apothecary Genetics and describes Barney’s Farm as a later breeder working with the genetics.4 Its own Grape Ape seed product and Sweet ZZ cross provide separately documented modern references.3,5

A strain-page figure and a breeder specification do not identify the potency of a retail batch.

  • Nevada supplied 95 of the 202 results; 44.1% came from one lab. This is not a representative nationwide sample.2
  • Matching uses product and strain labels. It cannot authenticate the original cultivar or distinguish every breeder version.
  • Historical flower tests do not establish current availability or the potency of a new batch.

This guide uses the published lab aggregates. Individual test rows are not available here, so a test-by-test histogram and CSV are not shown.

Measured terpenes and the limits of a strain profile

The highest medians among compounds with at least 50 measurements were β-Caryophyllene 0.42%, α-Pinene 0.25%, α-Humulene 0.24%. Individual terpene values appear in 99 tests.2

Leafly’s published order is myrcene, pinene and caryophyllene.1 That differs from this historical state sample. A different product population can produce a different ranking; ask for the analysis of the actual batch.

Grape, berries and a skunky edge

Leafly readers report grape, berry and sweet notes.1 RQS describes its own seed line with blueberry, candy, earth and skunk.3 Those are sensory descriptions, rather than a promise that every batch will smell the same.

What users report

Leafly’s leading reader-reported effects are sleepy, relaxed and hungry.1 These reports describe experiences, not clinical findings or guaranteed effects.

Effects are attributed user or breeder descriptions, not treatment claims or guaranteed experiences.

Growing reference: identify the seed line first

For its feminized photoperiod Grape Ape, RQS lists 50–60 flowering days, 60–100 cm indoors and 160–190 cm outdoors, with a late-September outdoor harvest.3 These are that breeder’s specifications. Confirm the version and provenance before applying them to other material.

Finding Grape Ape flower

This guide has no verified local inventory or price feed. Where lawful, check a local licensed retailer’s current menu and confirm the producer, batch analysis and product format. The flower statistics here do not describe cartridges or concentrates.
