Grand Blue
Across 16 laboratory results, Grand Blue tested between 14.2% and 17.2% THC, with a median of 15.6%. Most sites print a single number here. The spread is the more useful fact.
Laboratory chemistry
Every figure is a median across real lab results, with the middle 80% of those results beside it. A wide range means the same name tested very differently batch to batch.
| Cannabinoid | Median | Middle 80% | Samples |
|---|---|---|---|
| THC | 15.6% | 14.2% to 17.2% | 16 / below typical |

| CBG | 0.26% | 0.23% to 0.35% | 14 / below typical |

What this page does not tell you
- Whether the jar in your hand matches these numbers. Strain names are not standardised, certified or regulated. Research has found samples sharing a name that were as chemically distant from each other as samples with different names.
- How it will make you feel. This site holds no effect data, because no source publishes per-strain effect rates under a licence that permits reuse. An empty column is better than a borrowed guess.
- Anything medical. These are measurements, not claims about what cannabis does to a condition.
Sources
Where two sources cover the same analyte, the figure above is pooled over their combined samples rather than averaged — a median of two medians is not a median. Each source's own sample count is shown in the table.

Tried this one?
No one has reported on this strain yet. Yours would be the first. Effect data on this site comes entirely from people who used it, because no source of per-strain effect rates can be licensed at any price. Percentages appear once a strain has enough reports to be worth one.
