Growing cannabis outdoors is an exciting activity for growers all over the world. In this guide, we will provide you with crucial information on when to grow cannabis outdoors depending on your location in the northern or southern hemisphere. We will also answer frequently asked questions about growing in different months of the year and the use of greenhouses.
In the northern hemisphere, the key to successful outdoor cannabis growing starts in the spring. Here is a breakdown of the months:
Planting cannabis in February
Many customers want to start the season in February, but is it possible to grow cannabis in February? The answer is yes, if you are determined to grow in February in the northern hemisphere, a well-conditioned greenhouse could be the answer. Greenhouses can provide a more controlled and warmer environment for growing, which can help overcome the weather challenges of February.
Opt for cannabis strains that are resistant to cooler temperatures.
- We only recommend planting in February if you have a greenhouse and if you are looking to grow monster plants, by growing longer you can get giant plants. If this is not your intention, you can wait for warmer weather.
Planting cannabis in March
If we have to answer the question, when to grow cannabis outdoors, the most accurate answer would be in March. Planting cannabis in March is a much more suitable option compared to trying to do it in February in the northern hemisphere. In March, the arrival of spring means more favourable weather conditions for growing cannabis outdoors in the northern hemisphere.
As spring approaches, temperatures tend to rise, which is beneficial for healthy cannabis growth. Make sure night temperatures are not too cold, as freezing temperatures can damage plants.
In March, the days gradually lengthen, providing more hours of sunlight than in the winter months. This is essential for vigorous plant growth.
Make sure the soil is well prepared and enriched with nutrients before planting. This will provide the plants with a solid base from which to grow and flourish.
Planting cannabis in April
Planting cannabis in April in the northern hemisphere is a very suitable option and is an optimal time to start growing cannabis outdoors. We should take advantage of spring, as it is in these months that we should be growing cannabis outdoors.
In April, temperatures tend to be more stable and warmer as spring progresses in the northern hemisphere. This is beneficial for the healthy growth of cannabis plants.
In April, the days get even longer, providing enough sunlight for vigorous growth of cannabis plants. Sunlight is essential for proper plant development.
Monitor watering carefully, as plants will need more water as they grow and temperatures rise. Avoid overwatering to prevent problems such as overhydration.
Planting cannabis in May
Planting cannabis in May in the northern hemisphere is feasible, but keep in mind that you are starting a little later in the growing season compared to earlier months, such as April.
Still, successful growing is possible if you take the following guidelines into consideration:
In May, spring is in full swing in most regions of the northern hemisphere, which generally means warmer temperatures and longer days. Make sure night temperatures are not too cold, as frost can damage young plants.
The days in May are longer, providing an adequate amount of sunlight for growing cannabis plants. Make the most of natural light for healthy growth.
Growing cannabis in May in the northern hemisphere is viable, but consider that the growing cycle will be shorter, but with proper attention you can still get a good growing season.
Sowing cannabis in June, July and August
If you are thinking of sowing cannabis plants during these months, June may be feasible, although the growth phase will be very short and we will not obtain very large plants.
In the months of July and August it is not recommended to sow photodependent seeds, our advice is that, if you want to plant cannabis outdoors, you are still in time to make a growing of autoflowering seeds.
Growing in soil or in pots
The choice between pot or soil growing for cannabis cultivation depends on a number of factors, including your personal preferences, available resources and growing conditions.
When to pot outdoors
We will grow in pots when it is not possible to grow directly in soil, such as growing on terraces or balconies. Or when the quality of the soil is not good or suitable for growing cannabis.
To grow in pots we must use a good substrate that drains well and includes the necessary nutrients. As the months go by, the substrate will have lost all the nutrients and it will be very important to add the necessary fertilisers.
Make sure you choose a pot of a good size, for large plants the pot should be at least 25 litres (remember that the bigger the pot, the more the plant will grow). Another thing to keep in mind is the colour of the pot, use a white or brown pot, black pots get too hot and will not be good for the roots.
Growing cannabis on soil
To grow cannabis directly in soil you must first prepare the soil, which should not be left to the last minute. I recommend that you start preparing the soil a couple of months before growing your plants.
Start growing in small pots and once the temperature is warmer and the plants are a bit bigger and more resistant, transplant them directly into the soil.
Growing in potting soil tends to be more forgiving than growing in pots, so if height can be a problem you will need to use pinching techniques.
Lunar Influence
If you are one of those who believe in the influence of the moon in the natural world, you are not alone! Many cannabis growers have explored the idea that the phases of the moon can impact the growth and health of their plants.
Ancient wisdom suggests that the moon can play a role in agriculture, and if this piques your curiosity, we invite you to find out more. In our blog, we explore how the different phases of the moon can have a magical effect on your cannabis garden. It’s another layer of knowledge you might want to consider.

Growing cannabis outdoors in the southern hemisphere
If you are in the southern hemisphere, the growing cycle is reversed. Here are the key seasons:
- Spring (September – October): Start the germination process indoors and then transplant your cannabis outdoors.
- Summer (November – February): Plants will grow vigorously and flower during the summer. Carefully monitor hydration and pests.
- Autumn (March – April): This is harvest time. Be sure to assess the maturity of the buds before harvesting.
Faqs
- What are the dates for growing cannabis outdoors?
Northern Hemisphere: March to May: These are the ideal months for planting in most northern hemisphere regions. Avoid dates when frost is still a concern.
Southern Hemisphere: September to November: In the southern hemisphere, spring is the best time for outdoor planting. It starts in September and ends in November, depending on your exact location.
