Thirty-two minutes of garden number-crunching, powered by NotebookLM's Deep Dive format. Episode 001 covers how the calculators actually work and why getting the maths right matters more than guessing. Why 35g per square metre is all a new lawn needs, why overseeding only needs 15–20g, and the exact three-rule method that works every time.
