Three Years of Free Hash Education, and What Happens Next

No funny email gate games. No clickbait. A full course — slides, SOPs, the works — because I believed anyone who wanted to make hash at home should be able to learn how without paying tuition.

People told me I was crazy.

(“This is a $1000 course — and he just put it out there.”)

Maybe I was. But that free course did something I didn’t expect: it kept growing. v2.0. v2.1. v2.2. v3.0…?

Every version got bigger, and every version surfaced the same questions from new hashmakers hitting the same walls. My answers piled up in live Growhort walkthroughs, Discord threads, email replies, and podcast episodes — everywhere except the course itself.

So I did the thing I’ve been quietly working on all year…I turned the course into a full-fledged, 200+ page book:

Eleven chapters. Every method — dry sift, dry ice, water hash, rosin — plus the stuff the course never had room for: the updates. If you’ve been here long enough as a subscriber, you’ve gotten a taste of what else had to go in the book.

But for those that haven’t, this added (among other rewrites and improvements):

  • A full troubleshooting chapter

  • Hash Math (real cost-per-gram numbers, including my unflattering ones)

  • A chapter on building your home hash lab at three budget levels

  • A complete plug-and-play SOP library

  • A hashmaker’s glossary,

  • A bonus hobby hash hard candy recipe

Then (because why not double down?) I had a couple AI tools help me turn the hobby hash math (which I love but many hate) into interactive bonuses you can use to make it easy for you to crunch your own hobby hash numbers.

Then, at the last minute, I threw in a few real templates that I updated just this last week for my own home use that have been a big help. I’ve tried to pack in a bunch shitload of new value for first timers as well as those who’ve seen earlier version.

Full disclosure: yes, the new book costs money. $29.99 for the paperback, $12.99 for the ebook.

And I know exactly what some of you are thinking:

“But Ben, the course was free. Now you’re charging?”

Fair question.

This is not the old free course in a new wrapper.

It’s a ground-up rewrite with more than double the material, tested numbers from 90+ runs, three years of accumulated troubleshooting and in a paperback format you can dog-ear, splash with ice water, and keep on the bench next to your press. Think of it like homebrewing: the free recipe card got you started, but at some point you want the actual book on the shelf.

Not discounted. Free.

I’m calling it the Founders’ Edition, because that’s what you are. You were here when this was a slide deck. You asked the questions that became the troubleshooting chapter. The book exists because of you, so you get it first, and you get it free.

And for everyone who comes after? There’s a free sample (the first three chapters plus a full SOP) at hobbyhash.com.

Cover reveal is coming this week, but I wanted you to have a sneak peek below before the book goes live on Amazon on 7/29.

If you want to be part of the launch crew (get an early copy and a shameless request for an honest review) reply to this email and I’ll put you on the list.

Amor Fati.
