High on Home Grown, The Cannabis Podcast

In this week's interview, I sit down with Thomas Gibson, the founder and CEO of Grand Master LED, to talk about one of the most important pieces of equipment in any indoor grow: the grow light.

Thomas shares the story behind Grand Master LED, explaining what inspired him to start the company and how it has grown into one of the most respected names in high-performance LED lighting. We discuss the latest developments in their lighting technology, take a look at some of their newest models, and talk about what growers can expect from the next generation of Grand Master LED products. We also get a sneak peek at the company's upcoming line of nutrients and the thinking behind expanding beyond lighting.

As the conversation unfolds, we venture away from cannabis growing and chat about fitness, health, and some of the sports injuries Thomas has picked up over the years. It's a relaxed, honest conversation covering entrepreneurship, innovation, personal challenges, and plenty of practical advice for growers looking to get the most out of their indoor gardens.

Whether you're interested in LED technology, growing better cannabis, or hearing the story behind a successful company in the industry, this is an interview you won't want to miss.

This week on High on Home Grown, we cover another busy week of cannabis news, from major legal changes in the United States to public health warnings, promising medical research, and some controversial political statements.

Macky: Texas bans hemp-derived THC products, leaving smoke shop owners and customers with questions 

Smee: The risks of cannabis gummies with fake sweet packaging - BBC News 

Billy: A Cannabis Flavonoid Stopped Up to 99% of Cancer-Cell Growth in Lab Tests 

John: Marijuana Has 'Horrific Health Risks' And No Medical Value, Former Trump Attorney General Claims

This week we discuss Texas' decision to ban hemp-derived THC products, exploring what the new law means for businesses, consumers, and the wider hemp industry. We also examine the growing problem of cannabis gummies being sold in packaging that closely resembles popular sweets, and why this continues to raise concerns about child safety and responsible regulation.

Billy brings us an exciting piece of early-stage medical research looking at a cannabis flavonoid that showed remarkable anti-cancer activity in laboratory studies. While the findings are promising, we also discuss why it's important to distinguish between laboratory results and proven medical treatments. Finally, we take a closer look at former US Attorney General Bill Barr's claim that cannabis has "no medical value," comparing those comments with the growing body of scientific evidence and the experiences of patients around the world.

Another packed episode covering cannabis science, policy, medicine, and the stories making headlines across the globe.

It's time for another Listener Mail episode, and this week the High on Home Grown community has sent in another brilliant mix of growing questions, cannabis myths, and a few completely random discussions that only Listener Mail can deliver!

We begin by helping a listener who's planning a brand-new grow room after moving house. We discuss the pros and cons of building a secure enclosure inside a garage, how to make it as smell-proof as possible, and the key things to consider when growing safely with young children around. We also dive into the best methods for long-term cannabis storage, including whether vacuum sealing is a good option and how to preserve your harvest for months, or even years.

The panel also tackles a common harvest question: can you dry your cannabis in the same tent you grew it in by simply turning off the lights? We discuss the ideal drying conditions, what to watch out for, and how to get the best possible cure. We also bust an old cannabis myth by asking whether Miracle-Gro really "sucks the THC" out of your plants, separating internet folklore from reality.

Of course, it wouldn't be Listener Mail without a few lighter moments. We compare cannabutter vs cannabis oil for making edibles, answer a couple of wonderfully ridiculous philosophical questions, and even try to make sense of one of Dave's mysterious text messages.

As always, it's another relaxed episode packed with practical growing advice, cannabis knowledge, community questions, and plenty of laughs along the way.

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.

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.

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.

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...
