What’s the best medium or best soil to grow cannabis in? There are a plethora of options when it comes to where to plant your cannabis plants, regardless of whether they are full term, semi-full term, or autoflowering. We’ll start with the most simple option which is planting in native soil.
The Advantages of Growing Cannabis in Native Soil
Before planting in native soil, evaluate whether your plants are likely to have success in native soil. Do you or your neighbors already have existing and successful gardens? Is there appropriate aggregate size and drainage? For example, if you have lots of large rocks without any ‘free dirt’ to uniformly surround your plants root ball, it may not be appropriate.
Another good tool to evaluate your soil is a soil sample which can be sent out to a commercial lab that services agriculture in the area. This may or may not be cost prohibitive, depending on your scale, coming in from $50-$100 per sample. These tests will tell you the availability of NPK, many micronutrients, the PH, the organic matter, the CEC (cation exchange capacity) and much more. Just getting the report alone may not be enough, as you have to have the knowledge base to interpret the report and then make good decisions from there.
Planting in native soil is likely to be the cheapest and most water efficient of your options, as most native soils have higher organic material and clay content than regularly available potting soil. It is also most likely to give your flowers unique smoking characteristics, in the same way wine gets imbued with the terroir of the soil the grapes are grown in.
There may be some drawbacks to planting cannabis in natural or native soil. Different soil types may have different drainage capacities, nutrient levels, or pH levels. Cannabis is an adept bio-accumulator, and for that reason can uptake heavy metals found in excess in certain soils. Testing the soil and making necessary amendments or adjustments, such as adding compost or organic matter, may be required to optimize conditions for cannabis cultivation. Additionally, outdoor cultivation in natural soil may be subject to regional climate conditions, local regulations, and potential challenges such as pests, diseases, or variable nutrient availability.
In summary, here are the main reasons native soil may the ideal cannabis soil for you:
- Nutrient Availability:
Natural or native soil often contains a variety of nutrients that can be readily available to the cannabis plants. This can provide a rich and balanced nutrient profile, reducing the need for additional fertilization.
- Microbial Activity:
Natural soil is typically teeming with beneficial microorganisms such as bacteria, fungi, and other beneficial soil organisms. These microorganisms can contribute to the breakdown of organic matter, nutrient cycling, and the overall health of the soil ecosystem. They can also enhance nutrient availability and help protect against certain pathogens.
- Water Retention and Drainage:
Natural soils usually have a well-balanced structure that allows for good water retention while providing adequate drainage. This helps maintain proper moisture levels for the cannabis plants’ roots, preventing both overwatering and underwatering.
- pH Buffering:
Natural soils often have natural pH buffering properties, which can help stabilize the pH level in the root zone. This can be especially beneficial for providing a consistent pH environment for the uptake of nutrients.
- Sustainability and Environmental Compatibility: Utilizing natural or native soil minimizes the need for importing or using synthetic soil mixtures, reducing the carbon footprint associated with cultivation. It also promotes the use of local resources and ecosystem preservation.
Depending on the location, using natural or native soil can be a cost-effective option compared to purchasing or preparing alternative growing mediums. The bigger the scale, the more likely you will be to need to use native soil. Large scale operations (½ acre – acre +) should be rethought if they require large amounts of purchased soil, and will only be possible in a young market.
