01 · The Math

A grow runs on numbers nobody writes down.

Here's what a first-timer usually burns through chasing a single harvest — gear they didn't need, nutrients they overpaid for, and plants lost to mistakes no one warned them about.

The green column is the same grow, done the way the book teaches it. Every green number has its chapters: what to do, what it costs, and what to quit buying.

$29 once. The mistakes cost you every single season.

02 · What's Inside

Seed to jar. Six parts, thirty-one chapters.

Every chapter ends with a short version and the one thing that actually matters — the catch the forums argue about for forty pages and never settle.

01Starting Right
6 Chapters
  • Picking genetics for your space, not a magazine's
  • Popping seeds so nearly all of them come up
  • The cheap propagation setup that beats the $200 one
  • Photoperiod vs. autoflower — and who each is really for
  • Clones without a fancy machine, and when not to bother
  • The first two weeks, where most grows quietly go wrong
02Light, Air & Room
5 Chapters
  • How much light you actually need (and what to stop buying)
  • Greenhouse, tent, or window — honest trade-offs of each
  • Airflow: the cheapest upgrade nobody makes
  • Heat and humidity without a climate-control bill
  • Reading the room by hand before you trust a gadget
03Feeding & Soil
5 Chapters
  • The living soil mix that feeds itself for a season
  • Why most nutrient schedules are selling you thirst
  • Reading a leaf: what it's asking for before it yellows
  • pH and runoff in plain English, no chemistry degree
  • Compost tea and the free feeds in your kitchen
04Trouble & Pests
6 Chapters
  • Spot mites, thrips and gnats before they take hold
  • Powdery mildew: stop it in the air, not on the leaf
  • The $6 spray that replaces a shelf of products
  • Root rot, over-love, and the drowning you can't see
  • Deficiency or lockout? Telling them apart, fast
  • When to cut your losses and save the rest of the room
05The Flip & the Stretch
4 Chapters
  • Flipping to flower at the right time, not the panicked one
  • Training and topping for weight, without stressing plants
  • Sexing early and cutting males before they cost you
  • Feeding the flower without burning the finish
06Harvest, Dry & Cure
5 Chapters
  • Reading trichomes to harvest at your high, not a chart's
  • The slow dry that makes cheap weed taste expensive
  • Curing in jars: the two weeks that change everything
  • Trimming without wasting half the good stuff
  • Storing a harvest so it's as good in month six

Thirty-one chapters. One honest book. No course, no upsell, no Discord you have to join.

03 · The Honest Part

The deal this book makes with you.

The "secret strain" that does the work for you
There isn't one. Genetics help; the grower decides. I tell you which parts are actually skill.
The expensive gear that "pays for itself"
Most of it won't. I tell you the few things worth the money and the pile that's just marketing.
The yield number posted to sell you something
I give you the real one — what a careful first grow actually pulls, not a headline.

04 · Early Growers

The first people through it.

★★★★★
"First real grow and I didn't kill it. The trouble section alone saved a plant I'd already written off — mites, caught early, exactly like he said."
Marcus T. · First-time grower
★★★★★
"What got me is he tells you when something doesn't work. Half of what I read online was folklore. This reads like advice from a guy who actually grows, because he clearly does."
Renae P. · Backyard greenhouse
★★★★★
"No fluff, no lecture, no course to upsell. Short chapters, real numbers, the catch at the end of each one. My cure finally stopped smelling like hay."

05 · Who's Otis

Who's telling you this.

I'm Otis. I've kept a greenhouse going for twenty-odd years and grown through every mistake there is — dead seedlings, mildew, harvests I rushed and ruined. I got good the slow way, one season at a time.

I'm not a guru and I'm not selling a lifestyle. I'm the guy people text when a plant's drooping or the leaves are turning and they can't figure out why.

This book is everything I'd tell you standing at the potting bench — written down once, plainly, so you don't have to text me at all.

06 · Order The Playbook

If it doesn't grow you a better plant, I don't want your money.

Read it for seven days. If it doesn't save you more than it cost, or it's just not for you, email me and I'll refund every cent — no questions, no hard feelings.

Pay once and it's yours to keep — on your phone, your tablet, your bench. No subscription. No upsell. No course.

07 · Questions

Questions people ask.

If you've never grown and want to start right, it's built for you. If you've grown a few times and keep hitting the same walls — mildew, weak yield, a cure that tastes like hay — it's built for you too. It's not a picture book of famous strains; it's how to actually grow one well.
No. I grow in one, but the method works in a tent, a spare room, or a sunny window. There's a whole section on honest trade-offs between setups, so you can get the most out of the space you already have instead of buying mine.
Home-growing laws vary a lot by country, state, and city — some places allow a few plants, some don't. Check your local rules before you plant anything. This book is educational: it teaches the craft of growing the plant, and it's on you to know what's permitted where you are.
The full book — six parts, thirty-one chapters — as a PDF and an EPUB, emailed the moment you buy. Read it on a phone, a tablet, a computer, or print it and get it dirty on the bench. It's yours to keep forever.
Not at all. It starts at the very beginning — picking a seed — and never assumes you know the jargon. Where a word matters, I explain it in plain terms. Careful beats experienced, and the book is written to make you careful.
Neither. One book, one payment of $29, yours forever. No monthly fee, no locked chapters, no Discord you have to join, no "advanced module" I try to sell you later.
Email me within seven days and I'll refund every cent. If the book doesn't earn its price back for you, I'd rather give the money back than keep it. No questions, no hard feelings.

Stop guessing at a plant that wants to grow for you.

Thirty-one chapters, seed to jar, for a fraction of what one botched grow costs you. One honest book. $29, once.
