The 5 Best Soils for Growing Weed
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.
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.
Fox Farm’s Happy Frog Potting 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.
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.
Nature’s Living Soil Organic Super Soil
From planting seeds to harvesting buds, Nature’s Living Soil’s Organic Super Soil has you covered through cannabis’ entire grow cycle. 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.
Red’s Premium Biochar-Based Soil
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.
Your soil’s nutrients and the water you provide need to link up to be available for and absorbed by plants’ roots. Biochar, a carbon-rich charcoal amendment, not only facilitates this process but it also provides a large surface area for microorganisms to live and thrive. Red’s Premium Biochar-based soil thus creates an ideal “habitat” for all the living beings that help your cannabis plants reach their full potential.
Aurora Innovations Roots Organics Formula 707
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.
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.
Sungro Black Gold All-Organic Potting Mix Plus Fertilizer
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.
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.
Every ingredient in Black Gold is organic, and it’s suitable for a wide range of environments, from patio containers to indoor hanging baskets. The bottom line: Black Gold is a reliable and high-performance base soil for cannabis. You can also get hands-on with this soil, since adding amendments as your plants grow is super easy.

black gold soil. anyone?
Back in the day the 1980’s (been out for some time..eh!) when I was somewhat active in growing around here blackgold soil was the go to soil for growing I don’t hear it mentioned anymore?
Is it the plethora of soils specifically blended and marketed for weed growing or are other soils that much better? Fresh off the fiasco I had with ocean forest mix, excessively low pH and what appears to be nitrogen burn with one of the plants and who knows what else was going on??
I’m doing the new grow (blue magoo) with a 50/50 mix of BlackGold Natural & Organic Potting Soil Plus Fertilizer & Waterhold Cocoblend Potting Soil. I did add extra azomite & glacial rock dust, myco & oats, bone meal, perlite, fish & kelp meal. pH is a nice 6.2-4 Vs. the OFM which was a nice 4!
I think your on track, don’t forget the Pictures

My understanding is that when any ‘meal’ is added you need to compost for at least 2 weeks and possibly 30 days before use.
Also, is the bone meal steamed or unsteamed? If it is very granular then it is powdery and I would not use it. Granular is slower release so is MUCH better. Myco doesnt do well is high P that has not been composted well. If it was a powdered type and already in then I would compost it for at least a few weeks or maybe a month.
Lastly, I like to add feather meal because it is a slow burn N rather than a fast.
My research tells me that when one adds a fast form of nutrient then a slow form to supplement is a good idea.
The most important thing is to compost your mix before you add living roots.
Have fun and enjoy!

Yes Compost it, I always cook home made soil mixes regardless of meal additions. The soil has to acclimate to the additions you make, you may get a explosion of certain bacteria after the first few days causing real imbalances, but once the soil has equalized and is in harmony with all of its components it will be ready to use. For me typically a month, gets turned twice a week.

The soil sat for almost 3 weeks I got the clones two weeks ago i’ll post some pics when i get a chance.
I got the clones from a dispensary 6″ tall unfortunately they had cut the light so they were trying to bud and were over watered
and looked a little sad I use b vites and alaska fish fertilizer when i transplanted them they are looking good now.
