High on Home Grown, The Cannabis Podcast

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.

This week we discuss the UK's largest-ever cannabis seizure, examining what it means for enforcement efforts and whether major busts like this have any lasting impact on the cannabis market. We also look at new research suggesting that cannabis legalisation does not lead to increased consumption rates, adding another piece of evidence to an increasingly debated topic.

Dr. Margaret brings exciting medical news as researchers identify a cannabis-derived compound that may provide pain relief without the intoxicating effects typically associated with THC, potentially opening the door to new treatment options.

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.

It's time for another Listener Mail episode, and as always, the High on Home Grown community brings the questions that get us thinking!

This week we discuss the relationship between compost and pest management, and whether using homemade compost indoors carries the same risks as bringing pests in from the garden. We also dive into outdoor growing, covering the common pests, diseases, and warning signs growers should be keeping an eye out for throughout the season, from powdery mildew and honeydew to insects and environmental issues.

We answer questions about reusing Grove-style curing bags, how long they last, and whether they need cleaning between harvests. The conversation then turns to travel, favourite holiday destinations, cannabis tourism, social clubs, and why consumption lounges haven't become more widespread in parts of the United States. Finally, we discuss what makes certain cannabis strains command such high prices, looking at genetics, rarity, breeding work, marketing, hype, and whether some strains are genuinely worth the premium.

As always, it's a laid-back mix of growing advice, cannabis culture, travel chat, and community questions, with plenty of laughs along the way.

In this episode, we welcome Boudica Seeds back to the show to tackle one of the most debated topics in cannabis culture: black ash vs white ash.

Does black ash really mean your cannabis is poor quality? Is white ash a sign of perfectly grown flower? Or have growers and smokers been chasing a myth for years?

We dive deep into the science and the speculation, discussing what actually affects the way a joint burns. From cultivation practices and nutrient management to drying, curing, moisture content, and rolling techniques, we break down the factors that can contribute to black ash and uneven burns.

We also talk about common misconceptions, what growers can do to improve the smoking experience of their harvests, and whether ash colour is really a reliable indicator of quality at all.

A fascinating conversation that challenges some long-held beliefs and offers practical advice for growers looking to produce cleaner-burning, better-smoking flower.

In this episode, Macky sits down with Dan from Legal Growers UK for an in-depth discussion about home cultivation, cannabis law, and the future of reform in the UK.

Dan joins us to explain the goals of Legal Growers UK, the arguments for allowing adults to grow their own plants, and some of the biggest misconceptions surrounding home cultivation. We explore the current legal landscape, discuss the challenges facing campaigners, and examine how home growing could fit into a sensible regulatory framework.

Along the way, we tackle some difficult questions, challenge assumptions from both sides of the debate, and look at what real-world reform could mean for growers, patients, and the wider public. Whether you're interested in cultivation, policy, personal freedoms, or simply want to understand the arguments being made for change, this conversation offers plenty of food for thought.

Here are the stories we covered in this weeks show:

Macky:  How paranoia led to the death of a 93-year-old in Desborough - BBC News 

Smee: 98% of UK mental health patients report improvement from medical cannabis - leafie

Three jailed after former nightclub converted into cannabis farm - BBC News 

Dr.Margaret:  Japan Health Ministry Announces Ban On Cannabinol 

John: New Changes To ATF Gun Form Put Medical Marijuana Patients On The Path To Restored Second Amendment Rights (Op-Ed)

We start off by covering a story showing that over 90% of people using cannabis for mental health issues say it has worked great for them. We then move on to a story claiming that cannabis-induced rage caused a man to beat his 92-year-old friend to death... even though the man had a long history of violent convictions. Guess which of those stories was covered by the mainstream media?!

Margaret tells us about the banning of CBN in Japan, and we discuss how that could affect THC, considering CBN is essentially a degraded form of THC. John brings a story about changes to gun ownership forms in the USA, arguing that with cannabis being rescheduled, restrictions on medical cannabis patients may no longer be appropriate. Finally, Smee tells us about three men in the UK who have been jailed for growing cannabis.

I hope you enjoy the episode!

In this week’s episode, we wrap up Season 2 of Grow Guides with a relaxed but important conversation about the reality of growing cannabis at home, and why it’s nowhere near as complicated as many people think.

We give a simple overview of the growing process from seed to harvest, touching on the key stages growers need to understand while also reminding listeners that perfection is not required to grow good cannabis. Too many new growers get overwhelmed by information online, worrying about every little detail before they’ve even planted a seed.

The truth is, cannabis wants to grow. Most of the learning comes from actually getting started, making mistakes, and improving one grow at a time. We talk about building confidence, keeping things simple, and not being afraid to jump in and learn through experience.

It’s a positive and encouraging end to the season, aimed especially at newer growers who might still be sitting on the fence about starting their first grow.

A huge thank you to everybody who has supported Grow Guides throughout Season 2. We appreciate every listener, every question, and every member of this amazing community. We’ll be back soon for the next season!

This week we spoke with Dan, a cannabis activist from the UK. Dan has some interesting ideas that he believes could help push the UK government towards legalising cannabis for recreational use. He is part of an organisation called Legal Grower UK, and we chat with him about his ideas, what he thinks is going to work, what he sees for the future of cannabis in the UK, and much more.

We also have a special livestream coming up with Dan! It will take place on Wednesday 3rd June at 10pm UK time, live on our YouTube channel. We need you guys there to help us challenge Dan’s ideas and find arguments against some of his points, so it should make for a really interesting discussion.

Join us for the session, it’s going to be a good show!
