Most outdoor weed growers will either dig a hole and add fresh soil for the plant, or grow their weed in pots. This will allow you to better control the growing medium and the amount of nutrients your plants receive.
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.
Soil and other media for outdoor cannabis growing
Here are some important considerations before starting an outdoor marijuana grow.
Most potting soils used in gardening are loam soils. If you’ve ever worked with potting soil, you’ll know that its composition is rich and diverse, and it looks dark and hearty. Beyond texture and color, the soil should smell rich and alive.
If you don’t have a suitable patch of earth to make a garden, containers can be placed on decks, patios, rooftops, and many other spots. If needed, you can move them around during the day to take advantage of the sun or to shield them from excessive heat or wind.
You must be careful not to wait too long to harvest because marijuana plants suffer a decline in health once they have completed the flowering phase.
It is imperative that you keep your marijuana healthy because blooming plants have a natural resistance to specific pests. You can add ladybugs and lacewings, as these predators keep harmful pests at bay while doing no damage themselves.
Obviously, your plants need water, and the benefit of growing outdoors is that your marijuana should be exposed to rainwater. However, in places like California, the hot summer months mean minimal rainfall, so you have to water your plants manually. The main danger is overwatering your cannabis. A good rule of thumb is that a large plant needs 10 gallons of water a day during hot weather.
Step #10: Grow, Enjoy, Repeat!
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.
Threats like moles, who push up from the soil beneath your plants, require extra planning. An excellent way to prevent them from causing damage is by building a fence around 2-3 feet beneath the soil. You can also use deterrents such as urine from predators like coyotes, to ward off rabbits, gophers, and raccoons. Household items such as garlic and castor oil are pretty effective deterrents, too.
The plant’s trichomes should have turned an opaque white color at this stage, too. This is a good indication that they are fully mature and ready for harvesting.
However, once the temperature goes below 42 degrees Fahrenheit, most varieties of cannabis will be damaged quickly. If excessively cold temperatures are a problem, use protection such as cold frames, hot caps, or cloches.
