For most first-time gardeners, we recommend buying a quality potting soil that will provide your plants with enough nutrients to get them through most of their growth cycle without having to add many amendments. This pre-fertilized soil—often referred to as “super-soil”—that can grow cannabis plants from start to finish without any added nutrients if used correctly.
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.
Weed plants will need full, direct sun for at least 6 hours a day. You may have a backyard, but it might not be great to grow there if it doesn’t get full sun every day.
It’s crucial to have a good understanding of the climate in the area you’re going to grow. Cannabis is highly adaptable to various conditions, but it is susceptible in extreme weather.
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.
Balcony: This can be a great spot if it gets good light—ideally, it faces south—and will usually get good wind. However, you may need to cover your balcony from peeping neighbors.
Soil and other media for outdoor cannabis growing
Relying on the power of the sun, you won’t need to spend a ton of money on an outdoor grow. You’ll need some soil, fertilizer, seeds or clones, and maybe a small greenhouse to get them started. You won’t need to pay for electricity for lights, AC units, or dehumidifiers, and you can even collect rainwater.
Don’t underestimate the therapeutic value of gardening. It’s relaxing to spend some time outside, roll up your sleeves, and get your hands dirty for a while. And there’s nothing better than smoking something you grew yourself.
Now here are a few examples of good and bad cannabis soil so you can see the texture you’re looking for!
This is what kind of soil to get if you don’t have any “good” soil available, but want something that is known to work for growing cannabis.
Example of “Good” Cannabis Soil Ingredients
Their Ocean Forest soil mix is “hotter” soil (higher levels of nutrients) that contains ingredients that cannabis plants love, including earthworm castings, bat guano, fish meal and crab meal. The nutrients contained in the soil will provide everything your plant needs for several weeks. Although it might give young seedlings just a touch of nutrient burn at first, they can be started in Ocean Forest soil and will soon be able to use the nutrients and start growing quickly. Some growers might put a little big of Happy Frog on top of a container of Ocean Forest, just to make it a little more gentle for seedlings the first week or two.
I think most growers agree a good cannabis soil should look dark and rich, with a loose texture that drains well and can hold water without getting muddy (you want wet soil, not dirt-batter!). But beyond that, what do you look for?
Organic Potting Mix
When cannabis growers talk about “super” soil, they’re usually referring to soil that has been amended with slow-releasing organic nutrient sources, and then composted for several months (learn more about super soil).
From Nature’s Living Soil, the Super Soil Original Organic Concentrate comes in a 1, 5, or 10 lb. bag. All you need to do is add your preferred organic potting media to complete your mix. It contains all organic ingredients that your plant will need to thrive.
Choosing the right type of soil can help your cannabis crop grow to new heights and produce a bountiful yield. Growing weed indoors has never been more affordable or accessible for growers of all skill levels.
Water retention refers to your soils ability to hold water. The best soil for growing pot indoors has balanced drainage and water retention properties.

FoxFarm’s Bush Doctor Coco Loco is a coconut coir potting mix meant to recreate the tropical jungle floor. Light and airy, it does this by incorporating layers of exotic coconut palm humus which can hold more than its weight in water while still retaining great drainage characteristics.
Big Rootz’s All-Purpose Potting Soil features a professional-grade composition at a budget-friendly price. This cheap soil for growing weed is meant for indoors or outdoor gardens and has been Certified Green Clean (CGC).

Keep in mind, the nutrients in your soil mix don’t last forever. At most, they can last a few weeks and require you to keep a close eye on any nutritional deficiencies or signs of overfeeding.
Cannabis potting soil requires proper soil drainage. When watered, the soil should not hold the water too much to where it pools on the top. If you have bad drainage, your plants can be vulnerable to root rot and mold.
