when do i plant cannabis seeds outdoors

Plant companions. “Plant beneficial companion plants like marigolds, basil, lemon balm, or lavender. Not only do they invite pollinator insects into your garden, but they also invite beneficial insects like ladybugs and lacewings, which will prey on cannabis pests like aphids,” recommended Natalie Cox, a horticulturist and cannabis educator in Canada.

Choose a strain for your region or microclimate. Some strains do better in some climates than others, and strain genetics will have a big impact on the growing season. In the northern half of the US where the season is cooler and shorter, growers might want to grow indica-dominant strains, whereas sativas will do well in the more hot and humid southern states that have longer growing seasons. Type of soil, volume of rain, and abundance of sun versus shade are other microclimate variables in your microclimate to consider when choosing a strain.

Of course, you could always grow your plants in pots or containers. Lots of outdoor growers elect to use pots and other containers, and they offer the added benefit of being able to bring the plants out during the day and inside if nights tend to be cold.

Mid-to-late fall: harvest season

Timing the harvest is an art form in and of itself, though the general rule of thumb is on or around the Fall Equinox. Aside from brown pistils, a close inspection of the trichomes is helpful. Generally, growers look for trichomes that have an amber hue to them. When the plant is ready to harvest you’ll probably also see the fan leaves starting to yellow, curl, and dry out.

As the flowers fatten up, they might become too heavy for the branches to handle, and growers often give their plants some help with a trellis, bamboo canes, or another form of support. Extra nutrients like phosphorus are often given during the flowering stage.

For the final stage of a female cannabis plant’s life, most of its energy will be put into producing flowers. The flowering stage happens in three phases:

Before germinating your seeds, secure some high-quality soil. Organic soil provides everything your plants need to thrive: nutrients, beneficial bacteria, and synergistic fungi.

Start germinating your seeds indoors around February 27th if you live in a cooler climate. This date falls just before the full moon and encourages larger and more aromatic buds.

Are you looking for a specific flavour? Research the terpene profiles of the strains you’re considering. This will give you a window into the sensory experience. Do you prefer fruity or earthy? Citrus or candy?

Hours of Light

Prune your crop between mid-July and the end of August in preparation for harvest time. Snip away excess fan leaves during a descending moon in the waning phase.

With that said, indoor growers usually have less space at their disposal, less potential for massive yields, and have to splash money on electricity bills to run their setup.

For cannabis growers, the outdoor season inspires joy and fulfilment. Tending to plants under the blazing sun is its own form of meditation. In this guide, we provide our top tips for growing cannabis outdoors in 2021. Read up, prepare yourself, and achieve the harvest of your dreams!
