Watermelon Z lab report

No Watermelon Z flower result reached 30%; the strain's file is instead defined by an 18.60% median across 63 tests and a terpene subset where β-caryophyllene finished first in 68%, mostly from Nevada.1

Small sample: only 63 matched tests. Treat every figure on this page as indicative, not definitive.

Key findings

  1. Watermelon Z had no 30% total-THC results in this file; 40% of flower results reached the 20% cutoff and 19% reached the 25% cutoff.1
  2. The largest single outside THC value was 25% from AllBud; only 19% of flower tests got to that cutoff or beyond.1,2
  3. An 18.60% median puts Watermelon Z at 45th among 52 strains, between the neighboring medians for Trainwreck and Grape Ape.1
  4. On spread, Watermelon Z is 47th by narrowness out of 52, with a middle-half width of 7.32 points.1
  5. Terpene leadership was uneven but not locked: β-caryophyllene finished first in 68%, while limonene finished first in 32%.1
  6. In the Weedmaps shelf snapshot, Watermelon Z counted 216 flower store listings and appeared in 16 of 27 markets, ranked 23rd among 58 tracked strains.3

Are Watermelon Z THC listings too high?

Yes: for Watermelon Z, the checked outside THC listings run higher than the lab midpoint, with two of two single-value claims above the 18.60% median; the higher one, AllBud at 25%, was matched or passed by 19% of flower tests.1,2

The lower single value came from Leafly at 24%, a cutoff achieved by 21% of tests.1,4 The Weedmaps range of 21–28% contained 24% of results.1,5

These comparisons do not identify a specific package; the batch COA is the document for that.

Does limonene lead Watermelon Z terpene tests?

No: limonene was not the leader in most Watermelon Z terpene reports; β-caryophyllene led 15 of 22 reports, a 68% share, while limonene led 32%, so the lead is broad but not fully settled.1

The Leafly entry puts limonene in front; here, that terpene was the leader in 32%, compared with 68% for β-caryophyllene.1,4

The geography is lopsided: Nevada supplied 21 of 22 terpene reports, so the leadership split is mostly a view of flower tested in that market.1

Is Watermelon Z split between flower and concentrate?

Yes: exact-name lab records for Watermelon Z were split evenly between flower and concentrates at 36% each; among 195 records, 71 were flower, 71 were concentrates, 9.7% were shake and trim and 8.7% were pre-rolls.1 Only flower enters this site's figures.

A separate naming pool was larger: 232 results had extra words around Watermelon Z, 54% of all records containing that text; the leading examples were “Sour Watermelon Zkittlez” (48), “Stiiizy Infused Distillate Watermelon Zkittles Bulk” (21) and “Watermelon ZDP Flower” (19).1 Extra label words can point to different material, so our matching method leaves those out.

What this data cannot tell you

  • Full terpene-profile matching is not included because 22 reports with individual terpene values are below the 30 cutoff for that analysis.1
  • The lab comparison is omitted; Watermelon Z does not have 3 labs that each reached 20 tests.1
  • We skip THC versus total terpenes because the count of tests containing both measures is under 60.1
  • Trend analysis is left out because the file does not contain two years at least two years apart that each have 20 tests.1
  • Our lab file follows flower marketed as Watermelon Z from 6 states across 2019–2024, so it should not be used to verify any individual jar; use that batch's certificate of analysis instead.1
  • These chemistry results stop at measured compounds and cannot predict a person's experience with Watermelon Z.
