Growing cannabis in cold climates

How cold affects marijuana

And when we speak of cold, we are not referring to temperatures below zero throughout the day and for long periods of time, since in those places it is difficult for this plant to grow; we are referring to climates where temperatures are maintained at an average of between 5 and 10 degrees, as is usually the case in the north of most countries in Europe or North America, as well as countries such as China, Pakistan or northern India, where the cold is present along the year in some of its most mountainous regions.

Tips to combat the cold weather

For a long time and specifically in countries where it is not particularly cold all year round, as is the case in most European countries, a large number of marijuana growers devote to this task in the less hostile months of the year, i. e. those that range from April-May (germination and transplantation of seedlings and cuttings) to September-October (harvest), approximately, which is the time of outdoor harvest. The rest of the year, they devote to enjoying the production and prepare the next harvests.

Growing weed in winter outdoors

In many areas, winter is actually the driest time of the year, as well as being the coldest. If you are not facing issues of relative humidity, then cold dry air will present problems of its own in the grow room. If air is taken in from outside at a temperature of 10°C and an RH of 50%, it will contain water vapour at 4.7g/m³. If this air is heated to 25°C without the addition of extra moisture, its RH will drop to around 20%, which is far too low for healthy cannabis plants to grow.

Controlling humidity of cannabis grown in winter

Essentially, the volume of water in the air continues to condense as the temperature drops. And if you have ever grown cannabis before, you know that this can open up a proverbial can of worms (or better yet, mould) all of your plants.
