best time to plant marijuana seeds outside

Two rounded cotyledon leaves will grow out from the stem as the plant unfolds from the protective casing of the seed. These initial leaves are responsible for taking in sunlight needed for the plant to become healthy and stable.

Even if growing outdoors, a lot of growers will start their seeds inside under an artificial light to help them through this delicate stage of marijuana growth.

What are a weed plant’s growth stages?

As the sun reaches up high in the sky, your cannabis will want to as well. Make sure all of your plants are outside by the Summer Solstice.

Be sure to keep a grow journal to track the progress of your plants. Looking back on your notes will help you learn from mistakes and maximize the quality and quantity of your buds.

Once your seed has germinated, or sprouted, it’s ready to be placed in a growing medium, like soil. The tap root will drive down while the stem of the seedling will grow upward.

Greenhouses offer the best of both worlds. They make use of natural sunlight while offering the warmth and shelter of an indoor environment.

To germinate your seeds, poke a hole into the topsoil in a garden bed or pot. Place the seed in the hole and gently cover with soil. Add a little water. You’ll see the first shoot emerge within 2–7 days.

Guerrilla Growing

The vegetative phase begins once the seedling stage comes to an end. During this time, your plants will focus on photosynthesising and creating energy to fuel development. Expect a flurry of large fan leaves to proliferate throughout this phase. To maintain your plants, you’ll need to consider the following:

Physical barriers: Erect chicken wire fences and other barriers to prevent larger animals such as deer and birds from munching on your crop.

After selecting a location, you’ll need to choose a strain to grow. Here, you’ll need to consider your growing environment, and what kind of effect you’re looking for from your cannabis.

You’re not the only one wondering when to plant Marijuana seeds outdoors. Although it is a question that doesn’t have only one answer. Depending on what part of the world you live, the ideal conditions to plant marijuana seeds outdoors would be in the spring, between March and May (in the northern hemisphere). Ideally, during this time, your marijuana seeds should already be germinated and you can even plant marijuana seedlings that are a few weeks old outdoors. As we have mentioned in our other guides, to plant marijuana seeds outdoors is a numbers game. The more marijuana seeds you plant outdoors (if you don’t have the experience) the better your germination rates and eventual harvest will be. For Northern hemisphere climate conditions we don’t recommend to plant marijuana seeds outdoors, rather germinate and start growing the marijuana plant indoors until the weather conditions are ideal to take the marijuana plant outdoors.

If you live in a place that has a constant good weather then the season isn’t very important to take into consideration for you to plant marijuana seeds outdoors. In places with less abundant sunshine, the season would last roughly from March to August or September depending if it’s an Indica or a Sativa marijuana plant. In other regions such as equatorial or coastal regions, the issue of when to plant marijuana seeds outdoors is non-existent since the constant warmth and humidity will germinate the marijuana seeds outdoors without any worries of the conditions being too harsh for the seedlings, or not enough humidity and warmth for the marijuana seed.
