In what forms, and under what names, does G13 Haze reach testing labs?
Of 14 lab results under exactly the name G13 Haze, 100% were flower.1 Only flower enters the figures on this site.
Another 2 results carried a longer name that contains G13 Haze, 13% of all results with the name in them, led by “G13 Haze NYC Diesel” (1) and “NYC x G13 Haze” (1).1 Extra name words, cross markers and CBD versions mean these may not be the same plant, so they are excluded (how we match names).

What this data cannot tell you
- Which terpene leads test by test: only 2 of the 14 tests report at least five individual terpenes; the analysis needs 20.1
- Which strains have a similar terpene mix: needs at least 30 tests with individual terpene values (2 here).1
- Lab-to-lab differences: needs at least 3 labs with 20 or more tests each.1
- THC and terpenes together: needs at least 60 tests reporting both.1
- Change over time: needs at least two years, two or more years apart, with 20 or more tests each.1
- Price next to other strains: no market had 10 or more priced eighths of G13 Haze and of 3 other strains.2
- A particular jar: lab results describe flower sold under the name across 2 states from 2015 to 2022; only a batch’s own certificate of analysis describes that batch.1
- Effects: these are chemistry measurements. None of them predicts how a strain will feel to a particular person.
