High on Home Grown, The Cannabis Podcast

Macky has a story from Norfolk, where a couple in their seventies were found to have been running a cannabis farm from their home. It's certainly not what you'd expect to find when visiting your elderly neighbours!

Smee takes us back around 2,800 years to ancient Siberia, where archaeologists have discovered cannabis se...

Welcome back to Grow Guides! In Episode 4 of our 50-part series, we're looking at the different growing mediums available and helping you decide which one is right for your first cannabis grow.

There are plenty of ways to grow cannabis, and each growing medium comes with its own advantages, disadvantages and demands. Some are relatively hands-off, while others require regular attention and a much closer eye on what your plants are doing.

This week, we break down the most popular growing methods, including:

Living Soil: Growing with a living ecosystem that does much...

In this week’s episode of High on Home Grown, we dive into five very different cannabis stories from around the world, covering medical research, regulation, the future of the industry and some long-held beliefs about cannabis.

Macky looks at one of the biggest questions surrounding cannabis and medicine: can cannabis or CBD oil actually cure cancer? We look at what the scientific evidence says, what cannabis may be useful for, and why claims that cannabis can cure cancer need to be treated very carefully.

Smee looks at the ongoing debate around cannabis rescheduling in th...

It's Halloween on High on Home Grown! This week we're putting the cannabis news and growing talk to one side for a special Halloween episode, where each of us brings along a scary story to share.

We also get stuck into one of our favourite subjects: horror movies. We chat about some of the films that have genuinely scared us, the horror classics we love, the movies that probably shouldn't have...

Grow Guides Episode 3 is all about cannabis seeds!

If you're new to growing, choosing your seeds can be surprisingly confusing. Regular, feminized, autoflowering, photoperiod, CBD and all the different names and descriptions used by seed banks can leave you wondering what you're actually supposed to buy.

In this episode, we break down the different types of cannabis seeds and explain what each type is, how they grow, and why you might choose one over another.

We cover:

Regular seeds and what makes them different
Feminized seeds and why they are...

Smee brings us a story from Cu...

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 yo...

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.

n this week’s episode of High on Home Grown, we dive into some of the biggest cannabis stories making headlines around the world:

Over the next 50 episodes, we're going to take you through the process of growing cannabis step by step, covering everything from planning your first grow and choosing your equipment right through to harvesting, drying, curing and beyond.

And where better to start than with the question every new grower should ask before buying a single seed or piece of equipment: what exactly do you want from your grow?

We discuss winter growing, keeping the environment stable and the challenges of running tents in an outd...

This week on High on Home Grown, we welcome back a very good friend of the show, Jordan River, host of GrowCast!

But, as usual with Chad, we don't spend the entire...

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...
