Canna Haus Farms / Field guide 05

From plant
to rosin.

Follow the connection between the living plant, its resin, and the finished product. This guide explains the terms, the role of water treatment, and the batch information that helps make the process transparent.

Follow the process
01 / Single source

One team.
Every stage.

The process begins before the wash, and it does not end at the press.

This page covers the overall sequence. The individual field guides explain growing environments, consistency names, and micron terminology.

We work with ice water, heat, and pressure. Our live rosin is made without hydrocarbon extraction, artificial flavors, or reintroduced terpenes.

Keeping the cultivar and harvest connected to the finished batch gives the process context. Genetics, growing conditions, and harvest differences help explain why two batches can have different aromas, appearances, and textures.

02 / Follow the resin

How a harvest
becomes hash.

  1. 01 / Cultivate✳

    Grow

    We select cultivars for their resin and grow them in the environment suited to the run: indoor, greenhouse, or sun-grown.

    The plant sets the starting point
  2. 02 / Preserve❄

    Harvest fresh

    Plants chosen for live rosin are harvested and frozen fresh, rather than dried and cured first, to carry the harvest into the wash.

    Fresh-frozen material
  3. 03 / Separate◌

    Wash

    Cold water and gentle agitation separate trichome heads from the plant. Mesh screens collect the resin in different size ranges.

    Ice + water + mesh
  4. 04 / Evaluate◇

    Dry + select

    We dry the collected water hash and assess each wash and micron range before choosing the material for its finished expression.

    Selection by batch

Not every cultivar or harvest produces the same result. The selection depends on the resin in front of us, not a preset promise for every run.

03 / The water we use

RO water.
UV treatment.

Water comes into direct contact with the flower. Its preparation is part of our process.

We specifically use reverse-osmosis (RO) water to wash our flower. RO is a membrane-filtration process that reduces dissolved minerals and other substances in the source water.

Before the water is used to wash the flower, it passes through a UV filter as an additional disinfection step. UV light is used to inactivate bacteria that may remain in the water after filtration.

RO and UV serve different purposes: filtration reduces substances in the water, while UV targets microorganisms. This treatment applies to the wash water; it does not mean the flower or finished product is sterile, and it does not replace batch testing.

04 / Understand the language

What the
words mean.

“Live,” “solventless,” and “full melt” describe different aspects of a product.

01

Live describes the starting material

In this context, “live” refers to flower that was frozen fresh instead of dried and cured before processing. It describes the starting material, rather than a potency level or a promise about effects.

02

Solventless describes the method

In cannabis terminology, solventless refers to mechanical separation without extraction solvents such as butane, propane, or ethanol. It does not mean a product is automatically free of contaminants; that is a separate question addressed by appropriate testing.

03

Full melt describes performance

Full melt refers to how thoroughly a hash melts with minimal residue. It is not a synonym for all water hash, and appearance or a micron range alone cannot establish that designation.

05 / Choose the expression

The paths
separate here.

Dried, selected water hash ↘
Keep unpressed

Full melt

Selected hash stays as collected resin. Clean-melting batches can be enjoyed without pressing.

Apply heat + pressure

Live rosin

Selected hash is pressed into rosin, then offered as fresh press or finished into cold cure or jam.

Full melt and live rosin share the same starting material. Their paths differ after the dried hash is selected.

Batch variation is part of working with plant material. Color alone does not establish quality, potency, or purity, and a familiar consistency does not make two harvests identical.

Explore the consistencies
06 / Read the finished product

The jar keeps
the story.

A finished product is more than its consistency or a single lab number.

01

Strain + harvest

For definitions of indoor, greenhouse, and sun-grown, see Cultivation. Cultivation

02

Micron + tier

For collection-range and tier terminology, see the Micron Guide. Micron guide

03

Expression + lab results

A COA reports results for a tested sample. Check the report’s sample identity, date, and scope. Lab results (COA)

A certificate of analysis reports results for the sample submitted and the tests performed. Check that the batch or lab identifier matches, review the report date, and distinguish cannabinoid potency from contaminant screening. A THC percentage cannot tell the whole story.
