This plant is growing in Fox Farm Ocean Forest Soil

Now here are a few examples of good and bad cannabis soil so you can see the texture you’re looking for!

Usually an organic potting mix does not have enough nutrients to last your plants for more than a few weeks, so it’s a good idea to always supplement with cannabis-friendly nutrients, especially in the flowering stage when your plant is making buds and needs lots of extra Phosphorus and Potassium.

Good Cannabis Soil
Another light, rich soil mix with great drainage. Although there is a wood chip in this picture, for the most part the mix is completely composted and broken down. It’s normal to see some wood pieces in composted soil, but you don’t want to have to wait for a lot of wood to break down while your plants are growing – you want all that rich nutrient goodness to be readily available to your plant roots

Generally, anything labeled as an “organic potting mix” will work. This type of mix hasn’t been amended with chemical slow-release nutrients, which is one of the main things you want to avoid with soil for cannabis. I know it sounds like heresy, but even the Miracle-Gro version of “organic potting mix” will work okay, because unlike their original potting mix it doesn’t contain chemical nutrients (though it still has poor drainage and moisture retention – almost any other type of organic potting mix is better!).

Although that list looks vague and complicated at the same time, the requirements you want to meet are actually pretty simple; let me break it down!

Example of “Good” Cannabis Soil Ingredients

Super Soil has a colony of micro-organisms living in the soil which form a symbiotic relationship with your plant roots. They deliver nutrients to your plant, and in return they eat the sugars that get secreted by your roots!

Good Cannabis Soil
This soil has quite a bit of perlite, which is a good choice if you plan to feed heavily with nutrients and supplements since the extra perlite prevents nutrient buildup in the soil

Is this soils Ph ok for growing marijuana?? The only clues you really have are in the name, and on the web site it says its for slow growing plants that need fast drainage. Help greatly appreciated I have 5 Goot mitsy beans, just dont want to fuck it up.

I think you’d be fine, but don’t forget to check the pH of the mix, after all it has a wetting agent in it which might affect your plants.

Ha nice avatar, that nasty dirty sanchez.

If your soil strays slightly higher than 6.3 or slightly lower than 5.8, the plant will still survive but it won’t produce as well . Keep your soil around 6 for the best crop.

Keep in mind that numbers above 7 are basic (alkali), while numbers below 7 are acidic.

Best Soil For Indoor Cannabis

Of course, that variable can be controlled by growing your cannabis indoors (where the plant needs closer to 18 hours of fluorescent light).

Best Soil For Outdoor Cannabis

The organic super soil, in particular, gives you the right balance of carbon, nitrogen, phosphorus, and a whole host of other nutrients to ensure that your cannabis plant gets exactly what it needs during every stage of growth . Add to that the 420 fertilizer (you can make yourself) and you’ve got a great recipe for growing tall plants with plenty of buds and lots of cannabinoids.
