Growing marijuana outdoors produces a higher yield, gives your buds a unique flavor, and it’s far less energy-intensive than using indoor grow lights. Outdoor cannabis plants can grow up to 14 feet (4.3 m) tall and produce 4–8 pounds (1.8–3.6 kg) of quality weed per plant–and it’s not rocket science to grow cannabis outdoors. We’ve put together a comprehensive guide to tell you everything you need to know about picking a location, germinating marijuana seeds, and maintaining your crop to get the highest possible cannabis yield.
Quality soil is crucial to the success of your crop and one of the few factors that you have control over when growing outdoors.
Container gardens can be convenient as plants can be moved around the garden to maximize sunlight or protect them from harsh conditions such as rain, heavy winds, or extreme temperatures.
Avoid all-in-one fertilizers as they can be too high in nitrogen for the flowering cycle and damage any beneficial microorganisms that may be present in the soil. Instead, choose a line of nutrients created specifically for cannabis, and use its suggested feeding charts to avoid over- or under-feeding. Organic sources of nutrients are best, as they are a great source of beneficial microbes, but they may take longer to break down and become available to the plant. Both types of nutrients can be found in dry, pre-blended powders or liquid emulsions, but can also be made from scratch with the right ingredients. Organic compost tea, which includes nutrient-rich ingredients, like molasses and earthworm casting compost, is a popular homemade brew for cannabis farmers.
Cannabis has been cultivated outdoors for thousands of years, but before you go putting a seedling in the ground, it’s best to know how the process works and how to make the most of Mother Nature’s gifts. You should also have some idea of how to handle those unwanted gifts you’d rather return — pests and weeds.
For a small garden, hand-watering is the easiest, cheapest way to go. It also allows you to get familiar with each cultivar’s needs, and gives each plant the exact amount of water it requires. Irrigation systems can be convenient for a large number of plants or for times when you cannot be in your garden.
Keep this info in mind as you embark on your cannabis-growing adventure. The smallest adjustments can make all the difference — planting a week earlier, a week later, watering less, watering more, etc.
Plants grown from seeds are typically heartier and more vigorous than clones, as they produce a sturdier taproot that clones are not able to replicate. The vigor that comes from deep roots can be an advantage when dealing with harsh environmental conditions and pest pressures. The disadvantages of growing seeds are the additional attention required to germinate the seeds, the necessity to eliminate any males before they pollinate the females, and the high variability in growth characteristics that results from their genes.
Whether using seeds or clones, many cultivators start growing their plants indoors to ensure they are not exposed to damaging weather conditions as they develop their initial root system. The plants can be transitioned outdoors when the weather and light conditions are ideal. Extending the indoor vegetative growth period can help increase yields and allow growers time to select the best plants to be moved outdoors.
If you decide to use seeds, make sure you start them about a month before you would typically start clones to give them time to germinate and adequately develop their taproot.
