How To Prepare Trays for the Freeze Dryer
Before we dive into the how-to, it's worth understanding why tray prep is so important. When you spread ice water hash unevenly across your freeze dryer trays, you're setting yourself up for several potential issues. Thicker clumps of material take significantly longer to dry completely, which means you'll need to run longer cycles. This wastes both time and energy, two resources that commercial and home extractors alike need to manage carefully.

How To Decarb Rosin and Make Ampersand™ Powder for Edibles and Beyond
Rosin is one of the most incredible cannabis extracts you can make. No solvents, no mystery chemicals, just heat and pressure coaxing resin out of trichomes. But if you want to use that rosin in edibles, tinctures, or capsules, you need to activate it first through decarboxylation. And if you want to take things a step further, you can turn that decarbed rosin into a shelf-stable, easy-to-dose powder that works in drinks, food, or by itself.

The History of Cold Water Hash
The roots of cold water extraction reach back to the early-to-mid 1980s, when underground growers began experimenting with ice water as a tool for separating resin from trim. The fundamental principle was elegantly simple: submerge cannabis material in cold water, provide agitation, and observe as dense trichome heads sink while lighter plant matter floats. This physical separation required no solvents, no chemistry degree, just ice, water, and patience.
