Hobby Hash: A Crash Course in Making Solventless Products at Home (Paperback) (ISBN-13: 9781733209977)

Back in 2023, I gave away a free course on making hash at home. Hobby hash makers around the world took it. This book is that course, grown up.

I wrote Hobby Hash for one person: the home grower or hash lover who wants to make solventless extracts in their kitchen, garage, or spare room. No solvents. No lab. No $50,000 in equipment.

Every method in this book is one I've run at home. I share my real numbers, my real failures, and the exact steps I follow, so you can skip the expensive mistakes I already made for you.

Inside you'll learn:

- What solventless is and why it's the safest way to make extracts at home
- Dry sift: the easiest way to start today with tools you already own
- Dry ice hash: fast, high-yield extracts on a budget
- Water hash: hand washing in buckets or coolers, machine washing, and how to dry it with or without a freeze dryer
- Rosin: pressing flower and hash, plus making your own rosin vapes
- New and trending techniques worth watching (and the ones that aren't)
- How to build your home hash lab at three budget levels
- Hash Math: what it really costs per gram, and whether it's worth it for you
- Troubleshooting: what went wrong and how to fix it

This is a ground-up rewrite with expanded methods, a full troubleshooting chapter, real cost breakdowns, a complete plug-and-play SOP library, a glossary, and a bonus hard candy recipe.

Your purchase also includes:

• Free access to the Hobby Hash course community (redemption instructions inside the book)
• Free companion tools: an "Is It Worth It?" grow cost calculator, a hash yield estimator, a toll calculator, printable worksheets, and lab tracking sheets

You can make hash this week with what's in this book. The rest takes you as far as you want to go.
