Some growers, with an eye to the future, will consider a light top soil dressing of worm castings, compost, compost tea or seaweed just to ensure that future nutritional needs are met. Others will add some slow release organic nutrients such as BioTabs to the soil to ensure healthy future growth. You may also wish to get some less hardy companion plants such as Chamomile going to help deter pests later in the year.
What does your cannabis grow calendar look like?
Cannabis seeds that grow in uk climate need to finish inside the short growing season. One of the main challenges for those growing cannabis in the UK is selecting strains that will finish in time. If you want to grow cannabis outdoors, UK growers can choose between autoflower seeds and photoperiod feminised cannabis seeds.
Especially in the north, wet and windy weather is already becoming more and more common place. Many that grow cannabis in the UK find September and October to be the most critical months.
Which of these four types of climate do you live in?
Some outdoor growers like to try to control surrounding vegetation throughout the summer. In particular they like to stop nearby trees and bushes from taking sunlight from their cannabis plants. Outdoor pests such as aphids, whitefly etc can be a nuisance though they can be tackled with traditional methods as well as predatory insects (ladybirds etc).
Activity Not all farms are inhabited by the grower so watch out for signs that there is no one actually living there: unkempt front gardens, or if your neighbour never leaves out any bin bags on collection day.
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.
Conor Woodman’s film Exposure: Britain’s Booming Cannabis Business is on ITV on 16 October at 11.05pm
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.
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.
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.
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?
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.”
