It's another Listener Mail episode on High on Home Grown, and this week we've got a brilliant mix of practical growing questions, cannabis experiences, controversial opinions and, of course, some important biscuit-related business.
We start with a follow-up on amending living soil, asking whether it's actually better to wait until a new seedling has established itself before adding amendments, rather than potentially making freshly amended soil too "hot" for young plants. We also tackle a common concern for coco growers using organic inputs: why does mould sometimes appear in the growing medium before the seedling has even broken the surface? We discuss what might be happening and when growers should, and shouldn't, be worried.
The panel also takes on the question of outdated cannabis growing advice, looking at some of the common tips that have been repeated online for years and asking whether they still hold up with what we know today. We also share some of the biggest mistakes we've made during our own growing journeys and, more importantly, what those mistakes taught us.
Away from the grow room, we discuss dry mouth after taking edibles, whether dose and timing could play a role, and answer Lobby's question about our favourite cannabis extracts. And naturally, following last week's Jaffa Cake controversy, we return to the subject of biscuits, this time discussing everyone's favourite dunkable treats.
FreeNugz also returns with another wonderfully random question: if you could become a master of any musical instrument, which one would you choose and why?
Another relaxed episode full of useful information, personal experiences, community questions and the usual High on Home Grown chaos.

It's another Listener Mail episode, and this week we've got a great mix of practical growing questions, organic growing, plant biology and, naturally, some completely unnecessary but extremely important debates!
We discuss the best ways to deal with a calcium issue in an organic grow, including which amendments can help and how to avoid throwing unnecessary nutrients at your soil. We also look at why some cannabis strains begin forming and stacking buds much earlier than others, and what genetics, flowering behaviour and plant structure have to do with it.
There's also a great discussion about outdoor defoliation, with growers debating whether removing leaves throughout flower is beneficial for airflow or whether the plant should simply be left alone to make and use its own energy. We also tackle the question of how to reuse and re-amend super soil after a grow without constantly paying to have it professionally tested, and what growers can look for themselves when deciding what their soil needs.
And because this is Listener Mail, we couldn't possibly finish without answering the really important questions. Is a Jaffa Cake actually a cake or a biscuit? Which fictional universe would the panel live in for a week? And, perhaps most importantly, who taught the first teacher?
Another relaxed episode full of growing knowledge, community questions, questionable philosophy and the usual High on Home Grown nonsense.

In this week's interview, I sit down with Jackson Farmer, who runs a specialist DNA and sex-testing company for cannabis plants. We take a deep dive into the science behind cannabis sex testing, looking at how plant DNA can be analysed to determine sex at a much earlier stage than growers would normally be able to tell by looking at the plant.
Jackson explains how the testing process works, what growers can learn from their plant's genetics, and how DNA technology could potentially save growers time, space and resources when planning a crop. We also get into the increasingly discussed issue of HLVd (Hop Latent Viroid), what it is, why growers are concerned about it, and how testing can play a role in identifying problems.
But this isn't all cannabis science! We also take a few interesting detours into dog fostering, Jackson's experiences outside the cannabis industry, and plenty of other subjects along the way.
It's a fascinating conversation that brings together cannabis cultivation, genetics, modern DNA technology and a few unexpected tangents. Whether you're a home grower interested in the science behind your plants or simply curious about where cannabis testing technology is heading, there's plenty to get stuck into.

In this week's episode of High on Home Grown, we take a look at some of the biggest cannabis stories from the UK and around the world, covering crime, medical research, changing regulations and the risks surrounding cannabis edibles.
Billy: Medical cannabis compound alleviates nightmares associated with PTSD
John: New York legalizes cannabis sales at farmers' markets, pop-up events
Margaret: Police issue warning about dangers of cannabis edibles after man stopped on M1
This week we discuss the tragic consequences that can surround the illegal cannabis market, from a murder reportedly linked to a tiny £25 debt to a huge international smuggling operation. We also look at some more positive developments, including promising research into cannabis compounds and PTSD, and New York's decision to allow licensed cannabis businesses to sell at farmers' markets and pop-up events.
Finally, we examine another warning about cannabis edibles and driving, discussing why edible cannabis can be particularly unpredictable and why understanding delayed effects is so important.
Another packed episode of cannabis news from across the UK, America and beyond.

It's time for another Listener Mail episode, and this week the High on Home Grown community has delivered another brilliant mix of growing questions, thought-provoking discussions, and the usual off-the-rails conversations that make these episodes so much fun.
We kick things off by discussing what to do when you accidentally snap a branch during plant training, comparing different types of tape for repairs and whether breathable options offer any real advantages. We also explore whether supercropping autoflowers is worth the risk, and answer questions about lollipopping outdoor plants, looking at how outdoor training differs from growing indoors.
The panel also discusses whether over-dried cannabis loses potency, how drying conditions affect the final product, and whether experienced growers should be paying more attention to terpene development than trichome colour when deciding the perfect time to harvest. Along the way, we answer a few fun questions, including which fantasy character we'd most like to be, and tackle one of Margaret's famous thought experiments about what we'd do if we suddenly inherited £100 million.
To round off the episode, the conversation drifts into one of our favourite rabbit holes: space, the possibility of extraterrestrial life, and what might really be out there beyond our little blue planet.
As always, it's another relaxed episode packed with practical growing advice, cannabis science, philosophical tangents, and plenty of laughs with the High on Home Grown community.

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.
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.
