## Resource

It's Listener Mail time again, and this week the High on Home Grown community keeps the questions coming, covering everything from grow room troubleshooting to podcast ideas, with plenty of laughs in between! We kick things off by discussing whether LED grow lights really cause calcium and magnesium deficiencies, or if there's more to the story than growers often realise. We also answer questions about transplanting autoflowers, when (or if!) it's worth doing, and the best timing if you decide to give it a try. The panel also chats about electrical safety in the grow room, how much equipment can realistically be run from a single socket, and why modern LED lighting systems sometimes seem to come with enough cables to wire an entire house! We also discuss whether LED fixtures should be cleaned, how often, and the safest way to keep them running efficiently for years. Away from the grow room, we answer questions about when outdoor cannabis plants typically begin their stretch in northern climates, whether UK growers should be worried about potential changes to seed laws, and even discuss the possibility of introducing more of Margaret's much-loved story time episodes in the future. As always, it's another relaxed Listener Mail packed with practical growing advice, community questions, plenty of banter, and the usual dose of Lobby Lobster madness. 🌐 Website: https://highonhomegrown.com💬 Discord: https://discord.gg/sqYGkF4xyQ📺 YouTube: https://www.youtube.com/highonhomegrown
