High on Home Grown, The Cannabis PodcastShow Notes
It's time for another Listener Mail episode, and this week the High on Home Grown community has sent in another fantastic mix of growing questions, cannabis science, and a few fun topics to keep the conversation flowing. We start by discussing how to manage high temperatures in the grow room, what excessive heat does to cannabis plants during both veg and flower, and the best ways to keep your environment under control during the hottest months of the year. We also break down the different types of cannabis seeds, explaining feminised seeds, hermaphrodites, S1s, R1s, and other breeding terminology that often confuses newer growers. The panel also shares their favourite indoor and outdoor seed companies, discusses whether week three is too late to defoliate, and dives into the debate surrounding decarboxylation, exploring when it's necessary, when it isn't, and the different opinions on using cannabis medicinally. We answer questions about getting autoflower seedlings off to the best possible start, covering seedling mixes, lighting, watering, and avoiding the common mistakes that can stunt young plants. Along the way, we also chat about the best films to watch while baked, whether edibles have ever surprised us after an afternoon nap, and plenty of the usual Listener Mail banter. Another fun, informative episode packed with practical growing advice, cannabis knowledge, and laughs from the best community in cannabis. 🌐 Website: https://highonhomegrown.com💬 Discord: https://discord.gg/sqYGkF4xyQ📺 YouTube: https://www.youtube.com/highonhomegrown

In this week’s episode of High on Home Grown, we dive into the latest cannabis stories from around the world, including new research challenging claims about cannabis and violence, a controversial UK sentencing, and some interesting developments in the European medical cannabis industry. Macky looks at new research examining the claim that cannabis makes people more violent. The study challenges some of the recent headlines suggesting a direct link between cannabis use and violent behaviour, and we take a closer look at what the evidence actually tells us. Smee brings us a story from Cumbria, where a cannabis grower was sentenced after police discovered a commercial-scale operation worth around £500,000. The case also attracted attention after the judge apologised to the defendant for the timing of his sentence, which was handed down on his birthday. Billy has two short stories from the European cannabis industry. We look at the rapidly increasing movement of medical cannabis from Portugal into Spain, before turning to Cronos and its acquisition of a cannabis producer in the Netherlands connected to the country's ongoing cannabis trial. Two stories, but both highlighting how quickly the European medical cannabis market continues to develop. John is taking the week off, so unfortunately we're John-free this time around! Margaret looks at new research into prenatal cannabis exposure and its potential effects on children's brain development and behaviour. The study reports subtle differences in brain structure and behavioural measures among children exposed to cannabis during pregnancy, giving us plenty to discuss around what the research does and doesn't actually prove. As always, we take a look beyond the headlines and get stuck into what these stories really mean for cannabis users, growers, patients and the wider industry. 🌐 Website: High on Home Grown💬 Discord: Join the High on Home Grown Discord▶️ YouTube: High on Home Grown on YouTube
Grow Guides are back with Episode 2, and this week we’re talking about one of the most important parts of planning your first grow: what equipment do you actually need? There are thousands of different products, gadgets and pieces of grow equipment available, but how much of it do you really need? And more importantly, what equipment is right for the size of grow you are planning? We break it down by grow tent size, looking at 2ft x 2ft, 2ft x 4ft, 4ft x 4ft and 4ft x 8ft grow tents, and discuss what you need to build a suitable setup for each one. We cover the important stuff including: Grow tents and choosing the right sizeWhat sort of grow light you need for each tentExtraction and ventilationCirculation fans and air movementTemperature and humidity monitoringTimers and controlling your equipmentpH meters and why they matterEC Meters and when you might need oneThe smaller pieces of equipment that are easy to overlook The aim of this episode is to take some of the confusion out of buying grow equipment. Rather than simply telling you to buy the biggest, most expensive setup available, we look at what makes sense for different grow spaces and different growers. Whether you're planning a tiny 2ft x 2ft tent or you're dreaming of filling an 8ft grow tent, this episode should help you understand what you actually need before you start spending your money. This is Episode 2 of our new 50-episode Grow Guides series, where we're taking you step-by-step from planning your first grow all the way through to harvest and beyond. 🌐 Website: High on Home Grown💬 Discord: Join the High on Home Grown Discord▶️ YouTube: High on Home Grown on YouTube
This week on High on Home Grown, we’re joined by Aaron “Professor Potgrower” Zeeman, a Hawaii-based cannabis breeder, author and cannabis culture advocate. Aaron has spent more than 30 years in Hawaii and founded Big Island Genetics, where he works to preserve and breed Hawaiian heirloom cannabis genetics. Aaron joins us to talk about his book, The Hemp Ritual Handbook, a fascinating look at the culture, history and traditions that have surrounded cannabis for generations. It’s much more than a book about growing cannabis, exploring the rituals, experiences and culture that grew up around the plant long before legalisation and the modern cannabis industry. We also get deep into Hawaiian cannabis genetics, the legendary strains associated with the islands and the importance of preserving the genetics that have been passed down through generations. Aaron explains what he is doing through his breeding work in Hawaii and why keeping these old lines alive matters. From Hawaiian heirloom genetics and breeding to cannabis culture, his book and the history behind some of Hawaii’s most famous cannabis, this is a fascinating conversation with someone who has spent decades living and working with the plant. If you’re interested in cannabis history, genetics, breeding or simply the stories behind the plants we grow today, you won’t want to miss this one. 🌐 Website: High on Home Grown💬 Discord: Join the High on Home Grown Discord▶️ YouTube: High on Home Grown on YouTube
n this week’s episode of High on Home Grown, we dive into some of the biggest cannabis stories making headlines around the world: Macky looks at new research into cannabis use among older adults in the US. The study found that cannabis use is becoming increasingly common among people aged 65 and over, with 11.4% of older cannabis users meeting the criteria for cannabis use disorder. Smee brings us a story from Bedfordshire, where three men have been jailed after turning a former pub into a large-scale cannabis growing operation. Police discovered 13 cultivation rooms containing more than 1,200 mature cannabis plants, with the crop estimated to be worth up to £1.1 million. The three men received a combined sentence of more than 18 years. Billy is unfortunately not well this week, so we're flying one man down! John takes us over to the US, where the $28 billion hemp-derived THC industry is fighting to avoid a looming federal ban. With new federal restrictions threatening to seriously impact the industry, businesses are pushing for regulation rather than an outright ban. Margaret looks at a major review from researchers at King's College London examining the relationship between cannabis use and violence. The review analysed 63 studies involving more than 265,000 people and found an association between cannabis use and an increased likelihood of both committing and experiencing violence. The researchers also stress that an association does not by itself prove that cannabis is the cause. Another week, another pile of cannabis stories for us to get stuck into. As always, we take a look at what the research actually says, what is happening in the cannabis industry, and what these stories could mean for growers and consumers. 🌐 Website: High on Home Grown💬 Discord: Join the High on Home Grown Discord▶️ YouTube: High on Home Grown on YouTube
