25%+ THCa · Lab-tested
These are our strongest batches: THCa flower that lab-tested at 25% THCa or higher, sorted from the highest result down. The figure comes from each batch’s third-party Certificate of Analysis, and every strain is DNA-tested to confirm its name — so you know both how strong it is and what it is.

A product appears here when its lab THCa result is 25% or higher, and the order follows that number. Nothing is placed by hand. Because the list is driven by lab data, it changes as batches rotate — a strain can appear, drop off, and return with a new harvest.
Potency is batch-specific. The same strain grown twice can test differently, which is why we publish results per batch on the lab results page rather than per strain name.
A higher THCa number means more THC once heated, not necessarily a better experience. Aroma, flavour and how people describe a strain depend heavily on terpenes, and two batches at the same percentage can feel quite different. If you’re new to THCa, a high-potency batch is not the place to start: begin with a small amount and wait before having more.
Our COA guide explains total THC (THCa × 0.877 + Delta-9 THC) and how to confirm the batch number, and the DNA verification page explains why a strong number alone doesn’t prove what a strain is.
High-potency batches are the first to go, so much of this list may show as sold out at any moment. We keep those strains visible, below anything in stock, because the list is a record of what our lab results show rather than a curated shelf. For what’s available right now, browse all THCa flower.
FAQ
On this page, any flower batch with a lab THCa result of 25% or higher on its Certificate of Analysis.
From the third-party COA for that batch, published on our lab results page. We don’t estimate or round up potency.
No. It means more THC after heating, which is not the same as a better experience. Terpenes shape aroma and character, and newer consumers should start with lower-potency options.
Potency varies harvest to harvest. We publish results per batch so the number you see matches the flower you receive.
No. Until December 11, 2026, hemp is measured by Delta-9 THC (0.3% or less by dry weight), which is shown separately on each COA. The federal rule changes that on December 11, 2026 — see our explainer. Not legal advice.
