During the first half of the season, the daytime period increases until the summer solstice, which occurs in the Northern Hemisphere on or around June 21 and in the Southern Hemisphere on or around December 21. While the daylight hours increase, the plant’s vegetative stage takes place. During vegetation, the plant will develop the roots and stems that will serve as the foundation for growth until flowering.
There are many options when it comes to types of soil and how you can plant your cannabis plants outdoors.
Choosing the best site for outdoor cannabis growth
Daytime temperatures between 75 and 85 degrees Fahrenheit, or 23.9 to 25.4 degrees Celsius, are ideal for cannabis, while temperatures above 88 degrees Fahrenheit (31.1 degrees Celsius) or below 60 degrees Fahrenheit (15.6 degrees Celsius) can delay growth. Cannabis is considered heat-tolerant, but sustained highs and extreme lows will usually lead to complications that could eventually kill your plants.
In the Northern Hemisphere, cannabis can be planted in early to mid-spring and usually harvested in mid-fall, depending on the cultivar. In the Southern Hemisphere, the growing season will be reversed, planting in early to mid-fall and harvesting in the middle of spring.
During the vegetative phase, the plants need more nitrogen in order to create the roots and leaves that serve as the base for flowering. During the start of the flowering cycle, the plants will require more phosphorus and potassium than nitrogen. Towards the end of the flowering cycles, once the majority of the nitrogen has been depleted, the plants will focus their attention on using the remaining nutrients. The lack of nitrogen is largely responsible for the vibrant purple and orange hues that can be seen on large fan leaves and throughout the plants’ colas.
Silty soil is the ideal growing medium. It’s easy to work, warms quickly, holds moisture, has good drainage, and contains a lot of nutrients. The best silty soil is dark, crumbly loam—it’s fertile and probably won’t need any amending.
It’s fun and relaxing
Some growers plant in containers on balconies or rooftops that are shielded from view, while some build heavy-gauge wire cages to keep thieves and animals at bay. Whatever you decide, think about how big you want your final plant to be—outdoor cannabis plants can grow to 10 feet tall or even more, depending on how much you let them go.
Heavy clay soils drain slowly and don’t hold oxygen well, so they will need to be heavily amended. A few weeks before you plant, dig large holes where you’ll be placing your weed plants and mix in big amounts of compost, manure, worm castings, or other decomposed organic matter. This will provide aeration and drainage, as well as nutrients for the plants.
In general, 5-gallon pots are a good size for small-to-medium outdoor plants, and 10-gallon pots or larger are recommended for big plants. Regardless of size, you’ll want to protect the roots of your plants from overheating during warm weather, as pots can quickly get hot in direct sunlight. This will severely limit the growth of your plants, so be sure to shade your containers when the sun is high in the sky.
Soil has three basic consistencies, in various ratios:
Having a constant breeze is good for your plants, and especially in hot climates. But if you live in an area with a lot of high winds, consider planting near a windbreak of some sort, like a wall, fence or large shrubbery.
For example, sustained temperatures of over 86 degrees Fahrenheit can prevent growth. On the other hand, temperatures below 55 degrees could kill your precious plants.
It is impossible to provide a ‘precise’ time to harvest. Most experts believe that you should harvest an indica strain eight weeks after flowering. Sativas usually require harvesting ten weeks after flowering. Strains that come from auto-flowering seeds should take ten weeks to grow from seedling to bud. These are just simple guides, however.
Step #2: Choose the Best Possible Location
We are assuming that you intend to grow your cannabis plants from seed. In this case, you should germinate indoors during the early spring. In a warmer climate, seeds can start to sprout by early April. If you live in cold weather, this process probably won’t happen until May.
High winds are a significant problem for cannabis growers as it can damage the plants. It can break branches, damage trichomes, and leave your weed vulnerable to disease and infestation. Any type of excess strain like this can over-stress the plants, causing the buds to produce seeds. You do not want this to happen.
It is also an outdoor growing guide designed for small-scale cultivation. It is crucial that you check your state’s laws before proceeding. For example, weed is legal for recreational use in Colorado. You can grow marijuana plants as long as you’re aged 21 or over.
