Full melt hash is a solventless cannabis concentrate made from intact trichome heads that liquefy when dabbed and leave little to no residue. It is the top tier of ice water hash, rated 5 to 6 stars, and it is made with ice, water, and micron filter bags instead of butane or ethanol. In the US, full melt hash can come from THC cannabis or from federally legal hemp that stays at or below 0.3% delta-9 THC.
What Does Full Melt Mean in Hash?
Full melt describes how cleanly a hash melts, not how strong it is. A true full melt sample is nearly pure trichome heads, so it bubbles, greases up, and vaporizes on a hot nail with almost no char left behind.
Lower grades carry more leaf matter, stalks, and dirt. Those plant fragments do not melt, so they scorch and leave dark residue, which is why they grade below full melt.

How Is Full Melt Hash Made?
Most full melt is ice water hash, also called bubble hash. Producers freeze fresh or dried flower, agitate it in ice water, and strain the mix through a stack of micron bags that sort trichome heads by size.
- Freeze the plant material so resin glands stay brittle.
- Agitate in ice water to knock trichome heads loose.
- Filter through micron bags, with 73 to 120 micron screens holding the best heads.
- Collect and freeze dry or air dry the hash, then clean it further with static or sieving tech.
Drying matters because moisture trapped in resin invites mold and dulls the melt. Cleaner separation of heads from stalks pushes a batch from 4 star toward 6 star.
What Do Hash Star Ratings Mean?
- 1 to 3 star: food grade, best for edibles or tinctures.
- 4 star: half melt, works as a bowl topper or in a joint.
- 5 star: dabbable with some residue.
- 6 star: true full melt, dabs clean.
Can Full Melt Hash Be Made From CBD Hemp?
Yes. Hemp flower grows the same trichome heads as THC cannabis, with a cannabinoid profile dominated by CBD and CBDA. Hemp full melt tends to test high in CBD, low in delta-9 THC, and it ships legally in most US states when the batch complies with the Farm Bill.
CBD resin often has a thicker, waxier consistency, so hemp full melt may need a slightly warmer dab than a THC batch. Aroma and flavor still come from the same class of terpenes.
How Do You Dab Full Melt Hash?
Use low heat, small scoops, and a clean banger. Full melt is delicate, so overheating burns terpenes and wastes the premium you paid for.
- Heat the banger to roughly 400 to 500 F, or run a cold start dab.
- Drop in a rice grain sized piece and cap it.
- Inhale slow, then swab the banger while it is still warm.
You can also top a bowl or add full melt to a joint, but dabbing shows off melt quality best.
How Should You Store Full Melt Hash?
Keep it in an airtight glass jar, away from heat and light. A short stay in the fridge slows terpene loss, but let the jar reach room temperature before opening so condensation does not add moisture.
Use it within a few months for peak flavor. Hash that dries out or picks up moisture will not melt as clean.
Is Full Melt Hash Legal in the US?
Hemp derived full melt with no more than 0.3% delta-9 THC on a dry weight basis is federally legal under the 2018 Farm Bill. Cannabis derived full melt follows state law and stays illegal at the federal level in most contexts.
Check your state rules before ordering, and buy from producers who publish third party lab tests for cannabinoids, terpenes, and contaminants.
