The best soils for weed don’t always have to be products specialized for cultivating cannabis. Sometimes, a good organic potting soil is all you need, and Sungro’s Black Gold all-organic potting soil is an excellent case in point.
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.
Still, Formula 707 has enough nutrients to last 10-14 days before you need to add anything. And for convenience, you can use the soil bag itself as a pot. Just cut off the top, poke some holes in the bottom, plant your seedlings and you’re ready to grow.
Designed for indoor and outdoor cultivation, Happy Frog potting soil takes care of young cannabis plants’ essential needs, from correct pH levels to balanced nutrients, including a vital combination of microbes and fungi from earthworm castings and forest humus.

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. Its loamy mixture contains an optimal blend of pumice and perlite for hydration and microorganism development, and its balanced nutrient blend won’t burn young cannabis plants. Those features have won this soil praise from gardeners of all stripes, cannabis growers included.
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.
Cannabis plants spring up like a literal weed. But growing weed optimally — in a way that allows it to express its best traits and produce trichome-rich flowers — demands care, attention to detail and a bit of trial-and-error. At the same time, there’s no better way to develop a closer, more connected and more rewarding relationship with cannabis than growing some yourself. To get you started, here’s our list of the five best soils for healthy weed.
Nature’s Living Soil Organic Super Soil
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 growing cannabis is an art, then the soil is the canvas, paint and even a little bit of the brush. As your “grow medium” (the material that your plants grow in), the balance of nutrients your soil contains shapes how your plants grow, how fast and abundantly they flower and how many buds they yield.

Now, you should know that some marijuana plants can auto-flower—this means they’re not dependent on how much light they receive for the flowering phase. Alternatively, they progress to the flowering period when they reach a particular period of development.
If you’re growing cannabis outdoors, that means the natural soil may either be sandy, clay, or loamy. However, some soil can be a combination of these types—they can also be clay+loamy, sandy+loamy, sandy+clay, etc. And of course, each type of soil has its pros and cons.

If you’re going to purchase a bag of soil from a garden store that has very few choices, make sure to look for the words “organic potting mix” or “organic potting soil.” It isn’t the perfect soil for the job, but it can do the trick.
This brand is also worthy to be mentioned. It’s another bag of soil used and loved by cannabis growers. The favorite of many is the Ocean Forest Mix because it’s primarily efficient at providing the appropriate soil conditions for your cannabis plants to grow to their full potential. Cannabis plants love this mix because it includes the following ingredients: bat guano, composted forest humus, crab meal, granite dust, Norwegian kelp, oyster shell, sandy loam, sea-going fish emulsion, shrimp meal, sphagnum peat moss, and worm castings.
If you don’t want to purchase a bagged soil and you’d rather make one, then you can follow these steps to make your own organic soil:

Here’s a recipe for you so you can mix your own auto-flowering soil:
This type of soil has proven its effectiveness for years. It’s the go-to soil for the cannabis grower. The brand even makes other preservatives like perlite, peat moss, compost, vermiculite, and earthworm castings, which you can utilize to augment the shortage of essential nutrients.
Sun Gro Horticulture’s line of Black Gold potting soils, specialty mixes, and amendments have helped many cannabis growers produce big yields and quality flower buds. Knowing how to use Black Gold for growing weed can be essential to a successful harvest.
