Soil, at a basic level, is defined as the topmost layer of earth in which plants grow—it’s a mixture of organic remains, clay, and rock particles. Cannabis plants thrive in soil rich with organic matter, and they need good drainage.
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 and other media for outdoor cannabis growing
Once you have an understanding of the climate in your area, you’ll need to consider a few things before planting your weed.
It’s fun and relaxing
Buying the right soil for an outdoor cannabis grow
You may need to put all of your plants in containers if you don’t have great soil. Also, if you’re unable to perform the heavy labor needed to dig holes and amend soil, containers may be the only way for you to grow your own cannabis outdoors.
Just to be clear, growing cannabis is a time-consuming process. However, it is also an extremely rewarding one. This is a guide for a first-time grower who wants to grow quality cannabis without breaking the bank. If this is your first outdoor grow, and you miss a single step, then you may end up with a disappointing yield.

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.
Protecting Your Precious Crop from High Temperatures
Look for a plot that gets direct sunlight early in the day and filtered sun later in the afternoon. It is also ideal if you can find a place that offers a constant breeze. However, bear in mind that this increases water consumption.
After the solstice, the available daylight hours decrease, allowing the plant to naturally transition into the flowering period. Cannabis is a short-day plant, meaning it will begin to flower as the nights get longer and the hours of sunlight decrease.
Wilting plants and dry soil are a direct sign that plants need water. Droopy leaves along with wet soil are a sign of overwatering. Both are common mistakes and can be avoided with some practice.
Avoid spraying synthetic insecticides on your cannabis plants as further research is needed to determine the health effects of smoking plants treated with synthetic chemicals. Organic pesticide and insecticide solutions can be effective if used properly. If you can avoid it, it is always best to not spray anything on your plants while they are flowering.
Beneficial insects, fungi, and bacteria can also be used to protect your plants from their parasitic or predatory counterparts. Jumping spiders, ladybugs, and other native, beneficial predatory insects can clear your crop of insects such as aphids and whiteflies. When sourcing beneficial insects, fungi, or bacteria, it’s important to research those which are native to your region.
Outdoor cultivators take what Mother Nature gives them and turn it into the best possible harvest. Many cannabis consumers prefer marijuana grown outdoors under the full spectrum of natural sunlight. That unique spectrum creates a greater variance of cannabinoids and terpenes than artificial lighting.
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.

Pests come in many forms, from large deer and gophers to small slugs and spider mites. Larger animals and pets can be kept out of the garden with fencing, while gopher wire beneath your soil beds can keep rats and gophers from eating the plants’ roots. Weeds will not damage cannabis, but they will compete for the nutrients in the soil and reduce the quality and yield of your crops. A light layer of mulch on top of your soil can prevent weeds from sprouting in the middle of your plants’ cycle.
