Why Grow Cannabis Outdoors?
Growing cannabis outdoors offers a host of benefits, making it a fantastic option for newbies and veterans alike. The most obvious advantage is the cost savings – by harnessing the power of the sun, you eliminate the need for expensive grow lights, ventialtion systems, and energy bills. Outdoor plants also have the potential to grow much larger than indoor plants, producing higher yields and stronger, more resinous buds when given ample space and optimal conditions. If you’ve ever fancied growing a cannabis tree, outdoor is the way to go!
Natural sunlight provides the full spectrum of light that cannabis plants crave, promoting vigorous growth and robust terpene production. Plus, ouutdoor cultivation is more environmentally friendly, reducing the carbon footprint associated with indoor growing. Finally, many growers find that outdoor-grown cannabis develops a richer, more complex flavor profile due to exposure to natural elements and organic soil conditions.
Finding The Right Outdoor Growing Spot
One of the great things about outdoor growing is that you don’t need a vast plot of land to be successful. While traditional gardens or greenhouses are ideal, you can also grow cannabis on a sunny balcony, in a window box, or even in an allotment space. The key is to choose a location with plenty of direct sunlight, good airflow, and protection from extreme weather conditions. If privacy is a concern, consider companion planting with other tall or bushy plants to keep your cannabis discreet while also benefitting the surrounding ecosystem.
How To Choose a Good Outdoor Cannabis Strain
Selecting the right strain for your outdoor grow is vital to your success. The first thing to consider is your local climate – some strains thrive in warm, Mediterranean-like conditions, while others are better suited to cooler, wetter environments. Autoflowers are often a great choice for regions with short summers, as they flower based on age rather than light cycles, ensuring a quicker harvest. Finally, Early/Fast strains give you most of the advantages of your favorite photoperiod strains, while knocking a couple of weeks off the flowering times – just the thing for a later start, or a shorter growing window.
Another factor is daylight hours – photoperiod strains require a specific balance of light and darkness to trigger flowering, so understanding your local daylight patterns can help you pick the best strain for your area. Resilience is also key – outdoor plants must withstand pests, mold, and varying weather conditions. Hardy, disease-resistant cannabis strains are ideal, especially for those growing in unpredictable climates.
Once you’ve factored in the above, then you can look at personal preference – yield potential, flavor profile, and effects. Do you want a high-yielding strain, a terpene-rich cultivar, or something with a specific cannabinoid profile? By taking all these factors into consideration, you can choose a strain that will not only survive but thrive in your outdoor garden.
Without further ado, let Seedsman recommend some of the best cannabis seeds for outdoor growing in 2025!
