It's another Listener Mail episode, and this week the High on Home Grown community has sent in another fantastic selection of questions covering everything from grow room science to keeping your harvest as discreet as possible.

We kick things off by tackling a question inspired by AI-generated growing advice: do cannabis plants breathe oxygen at night, and should you avoid watering before lights out? We separate fact from fiction and discuss how cannabis plants actually behave during their light and dark cycles. We also share practical tips for reducing the smell during trim jail, and explore the long-standing claim that classical music can help plants grow. Is there any science behind it, or is it simply another gardening myth?

The panel also discusses using the dry mode on modern air conditioners to control both temperature and humidity, whether it's a worthwhile option for indoor growers, and takes a closer look at nutrient mixing. We answer a question about CANNA's recommended feeding ratios, EC management, and whether diluting a correctly balanced nutrient solution is the best way to feed your plants.

Finally, we chat about what to do with cannabis roots after harvest, when it's time to replace your carbon filter if you're running high airflow through your tent, and plenty of the usual Listener Mail banter that makes these episodes so much fun.

As always, it's a relaxed conversation full of practical growing advice, cannabis science, community questions, and more than a few laughs along the way.

In this week's interview, I sit down with Neil from Worm Hole Junction, a worm farmer, educator, and content creator from Canada who's on a mission to help more growers discover the benefits of vermiculture and living soil.

We chat about how Neil got started in worm farming, what inspired him to turn his passion into a business, and why worms are one of the most valuable tools any organic grower can have. From producing nutrient-rich worm castings to improving soil biology, Neil explains how a simple worm bin can transform the way you grow cannabis and other plants.

We also discuss the current state of the Canadian cannabis industry, how things have changed since legalisation, and the opportunities and challenges facing growers and businesses today. Along the way, we cover composting, sustainable growing practices, and plenty of practical advice for anyone thinking about starting their own worm farm at home.

Whether you're already growing in living soil or you're curious about making the switch, this is an informative and entertaining conversation packed with tips, insights, and inspiration from someone who's dedicated his career to building healthier soils.

In this weeks cannabis news we discuss the following stories:

Macky: Cannabis smuggler knows most of his drugs mules 'will get caught' - BBC News 

Smee: Strain Review Roundup What Worth Smoking in July 2026

Dr.Margaret: Heavy marijuana smoking may increase cancer risk, researchers warn | ScienceDaily

This week we discuss a BBC report featuring a convicted cannabis smuggler who admits that many of the people recruited as drug mules are expected to get caught, raising questions about organised crime and the people being exploited to carry out these operations. Smee joins us with his latest strain roundup, highlighting what's been impressing him and what's worth checking out this month.

Dr. Margaret looks at new research investigating whether heavy, long-term cannabis use may be associated with an increased risk of certain cancers, and we discuss what the study actually found, its limitations, and why it's important to look beyond the headlines.

We also have an interesting conversation about the future of cannabis reform in the UK, following reports that Andy Burnham has reached out to Gary Youds and his team for advice on cannabis policy. Could this signal a serious shift in the conversation around legalisation if Burnham becomes Britain's next Prime Minister? We share our thoughts on what it could mean for patients, home growers, and the wider cannabis community.

Another episode packed with news, science, politics, and cannabis conversation from around the world.

It's Listener Mail time once again, and this week's episode is packed with practical growing advice, community questions, and the usual dose of High on Home Grown banter!

We kick things off by discussing one of the most common indoor growing pests: fungus gnats. The panel shares their favourite methods for preventing and controlling infestations, including biological controls like beneficial nematodes, and how to stop these annoying little pests before they become a real problem.

We also dive into one of the biggest decisions new growers face: soil or coco? We compare the pros and cons of each medium, explain why coco often produces faster growth, and highlight the common mistakes growers make when switching from soil to coco for the first time.

The conversation then turns to late-flower stress techniques, discussing whether methods like extended darkness, drought stress, or ice water actually increase resin production, or if they're simply long-standing grower myths. We also answer a great question about how we'd each spend £300 on a beginner grow setup, sharing what we'd prioritise, where we'd save money, and what we'd avoid.

Finally, we tackle an important question about bringing a pollinated outdoor plant back indoors, explaining how long pollen remains viable and what precautions growers should take to avoid accidentally seeding the rest of their crop.

As always, it's another relaxed episode full of useful growing knowledge, community questions, plenty of laughs, and even a philosophical discussion about just how much wood a woodchuck could chuck...

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.

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.
