Sand is easily permeable for root growth, for instance, but it does not hold on to water or fertilizer well.
In addition, you do not necessarily have to provide costly soil for your plants outside. But for the best results, you want good marijuana soil that will help your plants grow healthy and happy. DripWorks is here to offer you a few simple tips for finding and creating the best soil for growing marijuana outdoors.
Just like humans, plants need the right nutrients. The most important ones for your cannabis plants are nitrogen (N), potassium (K) and phosphate (P). These make up the ratios you will typically see on fertilizer labels.
Loam for Growing Marijuana & Other Crops
Growing cannabis outdoors offers many benefits. Firstly, it can be very affordable. You do not need to provide a structure like a greenhouse or high tunnel. In addition, artificial light is not necessary if you place it in the right spot in your yard, because your plants can benefit from the sun’s abundant and free energy.
Red’s Premium is another all-in-one, ready-to-use soil blend. But what makes it one of the best soils for weed is its stand-out feature: biochar. Biochar is an amendment that excels at protecting and promoting the growth of bacteria, fungi and other microorganisms that are essential for root development and strengthening your plant’s immune system.
Fox Farm’s specialized line of soils for cannabis are some of the most widely acclaimed grow mediums available. If you’re beginning your grow journey from the ground up, Happy Frog is an excellent soil to nurture seeds and seedlings.
If you’re planning on planting a large container cannabis garden outdoors, Roots Organics Formula 707 is a versatile and capable option. An organic soil designed with greater water-holding capacity, Formula 707 contains ingredients and beneficial microbes specific to using larger containers.

But just as important as what’s in this soil is what’s not: less perlite, less pumice, and fewer amendments. This makes Formula 707 a highly customizable soil, allowing you to add your topsoil and liquid nutrients at various growth stages depending on your cannabis plants’ needs.
At a price point that won’t put a hole in your pocket, Black Gold boasts all of the essential traits of a strong soil for growing weed.

Reviewers love the ready-to-use simplicity this soil provides: just plant, water and wait. For those growing on their own for the first time, this is one of the best soils you can buy.
If you’re digging through the literature on growing weed, you’ve probably seen the term “super soil” come up quite a bit. Coined by the legendary grower and seed producer Subcool, the term generally describes a neutral organic soil base that’s been enhanced with a comprehensive range of “amendments,” i.e., added nutrients and microorganisms. Using a super soil eliminates the need for liquid nutrients as your cannabis plants grow.
This is probably the most commonly purchased amendment and is ideal for practically any soil mix. It consists of airy ‘rocks’ known for their white hue. Perlite looks a bit like popcorn and improves drainage while adding oxygen. Use 10-20% to improve water retention. You can go as high as 40%, but you risk leaching nutrients faster. If you use Perlite and Vermiculite, don’t go above 50% for the two combined.
On the plus side, sandy soil is easy to prepare for cultivation, offers good drainage, and contains high oxygen levels. It is one of the best options for growing weed indoors.
Many soils will have a combination of at least two of the four types. Therefore, you can have sandy/silty, loamy/clay, silty/clay, and so on. If that isn’t confusing enough, there are different ratios of every soil type. It is an important consideration, however, because each one has its pros and cons.
Natural soil comes in four varieties: sandy, silt, loam, and clay. You are in for a nasty surprise if you think that soil is just one ‘type.’
This is a great option if you want to nurture your crop from seedling through to harvesting. This Espoma soil contains excellent nutrition for early-stage growth. You will need to begin with small pots, before transferring your growing plants later. It contains peat moss, perlite, and peat humus – not to mention a hose of nutrients that aid strong root growth.
The amount of work you must do depends on the balance of your existing soil. For instance, if it has high amounts of clay or sand, you’ll have to add large amounts of organic matter several times a year. You can add a two-inch layer of organic matter onto the surface of the garden. Then, you should work it into the first couple of inches of soil.
Loam has a dark color and is soft, dry, and crumbly when you hold it. Although it offers a tight hold on plant food and water, it drains exceptionally well. The air can freely move between the particles down to the marijuana plant’s roots.
There are a large number of soil brands available, which is both good and bad news. You get a lot of options. However, with so many choices, how do you determine the best soil for growing your marijuana? The key is to analyze your situation, and our guide will help do the rest.
