As August progresses, daylight hours and temperatures start to drop. The cannabis plant senses the reducing daylight hours and you may notice your photoperiod feminised plants are in bloom.

A winter walk along the river banks, through the fields and in the countryside can reveal promising future guerrilla grow locations which could be adapted to grow cannabis, UK winters have their uses!

Some growers, especially those in warmer southern regions, may be tempted to reach for their cannabis seed stash and germinate some seeds. Realistically however, most growers won’t want to risk putting their seedlings outdoors in April weather with the possibility of wintery showers always present. Instead, growers often keep their seedlings indoors (or in heated greenhouses/poly-tunnels) for a few weeks until the threat of bad weather has fully passed.

But if the weather hasn’t deteriorated too much, and perhaps with the aid of some shelter (e.g. a glass roof) it may be possible for some lucky southern UK growers to harvest something.

What’s the legal status of growing cannabis in the UK?

Understanding the limits of the grow season at various UK latitudes and locations is your starting point. From there, you should be able to grow autoflower seeds outdoors no matter where you are in the UK.

The diverse, changeable and unpredictable weather can mean that no two UK grow seasons are exactly the same. That can make it difficult to have a preferred strain which will always deliver, year in year out.

Ventilation Growers need to ventilate the plants with large extractor fans, which generally emit a low hum. If every morning, at exactly the same time, it sounds as if someone next door is starting up their hovercraft, then it’s probably a cannabis farm warming up for the day.

The latest Independent Drug Monitoring Unit report suggests there are now as many as half a million people growing cannabis in the UK, which equates to roughly one on every street. So how can you spot the cannabis farm next door to you?

Light Growers can’t get away from the fact that internal farming requires a lot of it: 2,000 watts running 12 hours a day in a small bedroom looks a lot like the sun, so look out for windows that are constantly blacked out to cover that up. Cannabis farms in spare rooms will have the tell-tale sign of curtains that never open.

Good neighbourliness If the grower is in residence then it can go the opposite way. Perhaps the most surprising tell for having a grower next door might be their over-the-top neighbourliness as they overcompensate in their efforts not to annoy you or make you suspicious as to what they’re up to. As one grower told me: “I’m the nicest, most law-abiding citizen on my street, because the last thing I ever want is to give someone a reason to want to call the police to complain about me.”

I n the course of making a film about Britain’s cannabis industry, I have learned a lot about how to spot a cannabis farm. I have been schooled by policemen who raid them, gangsters who rob them and growers who set them up and produce more than 80% of the cannabis smoked in the UK today.

But you may not be the only person trying to spot a cannabis farm on your street. The sinister side to these booming businesses is that they have become lucrative targets for harder and more violent criminals looking to rob them. These people are constantly on the look out for farms within our communities, which in turn exposes the rest of us to potential violence. What’s the solution? The dealers and criminals I spoke with all said that legalisation would put them out of business.
