From Seed to Strength: A Grower's Journey in Breeding Cannabis

Breeding cannabis isn't just about crossing plants — it's about patience, observation, and understanding how every seed tells a story. In From Seed to Strength, veteran grower and nonprofit founder Eric Penkauskas shares his decades of hands-on experience, blending lessons from farming, animal husbandry, and nearly thirty years of cultivating cannabis into a practical, down-to-earth guide for growers of all levels.

Inside, you'll discover:

🌱 The Basics of Cannabis Breeding — clear explanations of F1, F2, and beyond, how to work with both regular and feminized seeds, and what to look for when stabilizing traits.
🌱 Selection and Culling — why the plants you don't keep are just as important as the ones you do, with real-world stories drawn from Eric's background breeding pigs and applying those same principles to cannabis.
🌱 Practical Breeding Techniques — step-by-step methods for pollination, controlling pollen indoors, and managing traits like structure, aroma, flowering time, and resin production.
🌱 Avoiding Pitfalls — common mistakes, hermaphrodites, and what to do when things don't go as planned.
🌱 A Grower's Mindset — balancing science with intuition, learning from failures, and building genetics that matter to real people — not just hype.

Unlike technical manuals full of jargon, From Seed to Strength reads like sitting down with a grower who's been through it all: crop failures, unexpected successes, and the joy of creating seeds that can change someone's life. Eric also shares the mission behind his nonprofit, Free Seeds 4 Veterans, showing how breeding is more than a hobby — it's a way to give back, empower others, and pass on strength through cultivation.

Whether you're a home grower curious about making your first cross, or an experienced cultivator interested in refining your own line, this book gives you the foundation, encouragement, and real-world insight you need to succeed.
