Those growing cannabis in the UK may also consider LST (low stress training) for tying down particularly tall plants. June is a good time to start, before the plants get too large to easily manipulate.

How to grow cannabis outdoors in the UK? You will need good local knowledge of your climate, first frost dates etc. It also helps if you have some prior knowledge of which strains will grow well at your latitude/location. In climates like the South East and South West you should be able to grow photoperiod strains like Frisian Dew and perhaps other strains too.
Occasionally June can be very hot. You may need to check rainfall locally and for the next 2-3 months consider transporting water to your plants in the unlikely event of a persistent drought.

April often heralds the start of Spring for many in the UK. Mini heatwaves in April are not unknown, though over-ambitious outdoor growers should note that snow fall and frosts are still commonplace for several weeks to come. Spring flowers are making the most of the longer daylight hours and warmer daily maximum temperatures.
Smell Follow your nose. A cannabis crop takes about three months to produce. During the final four weeks, the plants stink. Earlier this year, Crimestoppers helpfully issued cannabis-farm scratch-and-sniff cards to 210,000 homes in the UK to help you identify the exact bouquet.
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?
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.
