What's new

A new name, a new device and a new box for the same hash.

TreeHash

Everyone called it TreeHash anyway, so now the box does too.

The new oven

A postless ceramic oven that runs at low temperature and respects the terpenes, two heat settings, a session preheat that keeps it from clogging, USB-C and a no-nonsense screen for battery and heat.

Rainier on the pack

New paperboard packaging with the topographic lines of Mt. Rainier, and the return of Demon Slayer, Electric Lemonade and Purple Hindu Kush.

How to use it

Five, three, two.

Five clicks turns it on or off. Three changes the heat, and two runs the preheat. The same instructions are printed on the back of the card.

How TreeHash is made

From frozen flower to rosin.

Ice-water hash takes only the trichome heads and leaves the rest of the plant behind.

Frozen at harvest

The flower is frozen whole within hours of coming down, before it dries. The terpenes that curing usually loses stay locked in the trichome.

Washed in ice water

Frozen flower is stirred gently in ice water. Cold makes the trichome heads brittle, so they break away and sink while the plant stays whole.

Sieved and dried

The heads come out through fine mesh and go into a freeze dryer. What's left is hash.

Pressed into rosin

Heat and pressure turn the hash into rosin, ready for the all-in-one's ceramic oven.

Lab results

We don't grade our own hash.

Every TreeHash batch goes to a state-licensed lab. The certificate of analysis is printed as a QR code on the box, and it lists the cannabinoids, the terpenes, and what's not in there. Pesticide-free and Washington DOH General Use compliant.
