It's time for another Listener Mail episode, where the High on Home Grown community brings the questions and the panel does its best to provide the answers!
This week we dive into one of the most dreaded topics for growers: powdery mildew, botrytis, and other plant diseases. We discuss how to spot the early warning signs, what conditions allow these problems to thrive, and the steps growers can take to prevent them before they become a crop-ending disaster.
We also answer a fun question about the origin of John's famous "hoooly!" catchphrase, explore why cannabis seeds can seem so expensive despite being produced in huge numbers, and discuss whether the cost is justified by breeding work, stability, testing, and market demand.
The conversation then turns to autoflowers in living soil, where we share tips for getting seedlings established successfully and avoiding some of the common pitfalls that can stunt growth early on. We also touch on the future of growing technology, discussing whether renewable energy-powered grow systems could become more common and affordable for home growers.
As always, it's a relaxed mix of practical growing advice, community banter, and a few laughs at John's expense along the way.
