How to Make Feminised Seeds at Home | Breeding Tips with Boudica Seeds | Grow Guides x Interview Special

In this in-depth episode of High on Homegrown, host Tommy Chong welcomes back Boudicca, a UK-based cannabis breeder and founder of BoudiccaSeeds.co.uk, for a detailed guide on how to make feminized cannabis seeds at home. Boudicca walks listeners through two methods: the traditional approach of over-flowering a female plant to induce male characteristics (producing pollen), and the more precise, modern technique using silver thiosulfate—a chemical solution that reverses female plants into hermaphrodites. The episode covers everything from sourcing materials like silver nitrate and sodium thiosulfate (with warnings about using distilled water and avoiding contamination), to the exact process of preparing the solution, applying it to plant nodes every two days, and identifying successful pollen production. Boudicca emphasizes the importance of timing, plant selection, and quarantine to prevent accidental pollination. He also shares practical tips on harvesting, drying, and separating seeds, as well as insights into cross-breeding strategy—such as which plant should be the pollen donor based on desired traits. The conversation extends beyond breeding to reflect on the cultural and generational shifts in cannabis growing, the decline of forums, the rise of AI, and the emotional toll of growing in a restrictive legal environment. Boudicca ends on a hopeful note, advocating for the preservation of breeding knowledge and the future of homegrown cannabis culture. Key takeaways include: (1) Making feminized seeds at home is achievable with basic equipment and careful technique, especially using silver thiosulfate; (2) Timing and application are critical—spray only the nodes every two days for 10–14 days; (3) Always use distilled water and clean, single-use tools to avoid contamination; (4) Harvest seeds after a short pollination window (1–2 days) to ensure uniformity and quality; (5) The plant receiving pollen often imparts more of its traits to the offspring, so choose wisely; (6) Drying seeds thoroughly after harvest improves longevity and germination rates; (7) Breeding is not just practical—it’s a creative, rewarding hobby that preserves genetics and fosters community. The episode closes with a warm, nostalgic tone, celebrating the craft of growing and the resilience of the cannabis community.
