When it comes to growing cannabis, picking the right soil mix is extremely important. If you ask yourself, what should I use to grow my plants? It is essential to remember that not all mixes are created equal. You need to pick a mix that will give your plants their best chance of growing big and healthy buds, but you must also choose one that won’t damage the environment.
Which soil mix to use for growing cannabis?
The most common question when choosing a soil mix is whether or not to buy a professional-grade mix from hydroponic stores. These soils might guarantee great growth rates and yields, but they can be costly. Even worse, they may contain ingredients that otherwise aren’t available for home growers, such as life and vermiculite.
We recommend that new growers utilize a proven mix like FoxFarm Ocean Forest. This mix contains all the necessary macronutrients for the healthy growth of your marijuana plants. Still, it also has an attractive price point and is available at most garden centers.
It might even be available in your backyard.
Another great alternative to professional potting soils is the Fiskers Organic Potting Soil. The Fiskers organic potting soil can be used to grow practically any variety of plant or flower. This makes it perfect for not only cannabis but other herbs and vegetables!
If you grow in pots, remember that they will dry out faster than planting directly into the ground. It would be best to consider using a larger pot with more soil. You might also consider adding water-retaining agents to your mix in order to combat this issue. One of our favorite additives is perlite. This will help aerate the soil and allow greater oxygen diffusion throughout the root zone. This is especially important during periods of intense growth when plants consume large amounts of nutrients.
Another popular additive used with FoxFarm Ocean Forest is Mycorrhizae fungi.
These beneficial organisms can significantly improve nutrient uptake and increase mold, mildew, and disease resistance. Our top recommendation for this additive is Root Maker mycorrhizal inoculant. This additive has shown remarkable results among some of the most experienced growers!
Whether you use professional-grade soils like Ocean Forest or a proven and tested soil mix like Fiskers Organic Potting Soil, remember that cannabis should be grown in the best possible conditions. Good luck and happy growing!

- Con: Not all additive products are created equal, so research before deciding on one best suited for you. Some additives may harm cannabis growth if they do not have the proper ingredients for nourishment.

What’s a Water Retaining Agent? How Does it Work?
Water-retaining agents are used to retain water for an extended period, while not allowing the mixture to become completely saturated. These products work by absorbing large amounts of water and holding them in their chemical structure. At the same time enabling small amounts of exchange between the water molecules and the air. This results in a much more efficient watering schedule for growers who are frequently stuck with very little rainfall during the summer months.
Some common examples include perlite. Pearlite is made from volcanic glass, pumice stone, or even rice hulls; all of which help to aerate soil mixes while at the same time retaining water. Another option is an additive called Spongolite. This also contains water-retaining agents alongside beneficial mycorrhizae fungi that can significantly improve nutrient uptake and increase resistance to mold, mildew, and disease. If you are growing in pots, remember that they will dry out faster than planting directly into the ground. To combat this issue, you should ensure your potting mix also contains a water-retaining agent.
