Grow Your Own Glow-in-the-Dark Mushrooms Grow real bioluminescent mushrooms using your own hardwood log. This DIY kit includes 10 actively colonized glow plug spawn of mycena chlorophos, ready for log inoculation (log not included). Spring and early fall are ideal seasons to inoculate logs, as moderate temperatures support healthy colonization. What You Receive • 10 colonized glow plug spawn • Step-by-step log inoculation instructions • Educational booklet about bioluminescence No laboratory equipment required — just a suitable hardwood log and basic tools. How It Works Drill holes into a hardwood log, insert the plugs, seal, and allow the fungus to colonize the wood. As the mycelium spreads, it produces a natural glow visible in dark conditions. Brightness increases over time as colonization expands and during fruiting. Colonization and fruiting typically occur within 1–5 months depending on conditions. Log Sourcing Suitable hardwood logs (oak, maple, beech and similar species) can often be sourced
