growing marijuana in pots outside

Cannabis plants require a large amount of nutrients over their life cycle, mainly in the form of nitrogen, phosphorus, and potassium. How much you need to add to your plants will depend on the composition of your soil.

The sky’s the limit with outdoor plants—you can let them get as big and tall as you want, as long as they’re manageable. One plant can potentially yield between a half-pound and full-pound of dried weed! Growing a handful of hands for yourself is more than enough. With an indoor grow, your space is a lot more restricted.

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.

Garden plot: Probably the most common outdoor growing spot, many will plant cannabis alongside other growing veggies.

Buying the right soil for an outdoor cannabis grow

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.

Here are some important considerations before starting an outdoor marijuana grow.

How to set up your 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.

Typically, outdoor growers will add amendments to soil when weed plants are transplanted outside. Outdoor amendments usually come in powder form that you mix in with soil.

Test kits are available to measure your soil’s acidity, or you can take a sample to your friendly local extension agent. If your dirt does not have the proper acidity, soil amendments are available to lower or raise the pH level in your soil. Your local nursery, garden store or extension agent can make some suggestions.

Silt soils have lots of minerals and retain moisture well. Like clay, however, this type of soil can become compacted and hard in certain conditions. It can also form a crust, making it difficult for moisture and nutrients to reach plants’ roots.

The optimal ratio for loam is 20% clay, 40% silt and 40% sand. Most folks think a pH of 6.0 is best for cannabis, with a range of 5.8 to 6.3 being acceptable. With a pH close to neutral, loam is typically in that zone or close to it.

Loam for Growing Marijuana & Other Crops

Of these types, loam is by far the best soil mix for growing marijuana plants and many other types of crops. Loam is a mixture of clay, sand, and silt, bringing forth the best qualities of these disparate types of soil while minimizing their worst attributes.

Sand is easily permeable for root growth, for instance, but it does not hold on to water or fertilizer well.

Four basic soil types exist: sand, clay, silt, and loam. Each has its pros and cons for gardening.

You will want to provide the proper amount of light and water to your plants, of course. A drip irrigation system can cut your water bills while improving the health of your plants.
