Finding the Cheapest Soil Growing Mediums
Growing cannabis can be an exciting venture, whether you’re a seasoned cultivator or just starting out. However, a common concern for many growers, especially those operating on a tight budget, is the cost of grow mediums.
In this article, we’ll explore the most cost-effective grow mediums for cannabis, ensuring you get the best value for your money without compromising on the quality of your plants. With the cost of gas, and diesel used to transport heavy bags of soil going ever higher, finding the cheapest growing medium for cannabis is more important than ever for growing quality cannabis plants.
Understanding Grow Mediums: The Basics
Before diving into the specifics of the cheapest grow mediums, let’s understand what a grow medium is. Essentially, it’s the material in which your cannabis plants grow. It can range from soil to more advanced hydroponic setups. The right grow medium will support your plant’s root system, provide necessary nutrients, and aid in proper water retention and drainage.
Soil: The Natural and Affordable Option
Using natural soil sourced from outdoors is the cheapest growing medium for cannabis. However there are some precautions that you should take before using this cheap and useful soil medium to grow your cannabis.
Soil is a popular choice for cannabis cultivation due to its natural abundance and nutrient-rich composition. It is easily accessible and can often be sourced locally, making it a convenient option for many growers. Good quality soil is beneficial as it contains essential nutrients vital for plant growth.
However, it’s important to be aware of the potential downsides. The quality and nutrient content of soil can vary significantly, which might affect plant growth. Additionally, soil can harbor pests and diseases, especially when using soil from the outdoors and bringing it indoors, posing a risk to your cannabis plants. When choosing soil as your grow medium, aim for a pH level between 6.0 to 7.0 and look for a texture that is light and airy to promote healthy root growth.
Its main advantages include:
- Natural Abundance and Nutrient-Rich Composition: Soil is widely available and often can be sourced locally. Good quality soil is rich in essential nutrients, which are vital for the healthy growth of cannabis plants.
- Convenience: Due to its easy accessibility, soil is a convenient option for many growers.
However, there are important considerations to keep in mind:
- Variability in Quality and Nutrient Content: The quality of soil, especially when sourced from outdoors, can vary greatly. This variation might affect the growth and health of cannabis plants.
- Pests and Diseases: Soil can harbor pests and diseases, particularly when it’s brought indoors from an outdoor environment. This poses a risk to cannabis plants.
- pH Level and Texture: When choosing soil, it’s crucial to aim for a pH level between 6.0 to 7.0. The texture of the soil should be light and airy to promote healthy root growth.
Using Outdoor Natural Soils Indoors
It is never a wise idea to bring outdoor soils indoors into your cannabis gardens, even if you don’t see any pests in the soil, there can still be many pest eggs, or harmful bacterial hiding in there. Since you are unable to see them, they will now be in your indoor soil and it could be weeks until you start to see the issues as a result of bring in outdoor soils.
The best way to make sure this does not happen is to pasteurize your cannabis soils from outside before using them in your indoor cannabis gardens. To do this you will need to follow these directions to make your outdoor safe for indoor use.
- Place your outdoor soil in a large turkey tray
- Place some tinfoil over top of your soil making sure it is wrapped well to keep the moisture in this will help with heating the soil
- Place your turkey tray of soil in your over
- “cook” the soil at about 275C for about 3 to 4 hours, if you are able we recommend using a meat thermometer to check that the center of the soil is heated to at least 175C this will ensure that anything such as pests or bacterial is killed off in the heating process
- remove the heated soil and let cool to room temperature
- your soil is now ready to remove and use in your grow room and be amended with organic nutrients as needed
Coco Coir: The Sustainable Choice
Coco coir, derived from coconut husks, stands out as an eco-friendly and sustainable grow medium. It is known for its excellent water retention properties, which can reduce the frequency of watering. This feature is particularly beneficial for maintaining moisture levels around the roots of your cannabis plants.
Despite these advantages, coco coir does require the addition of nutrients since it’s an inert medium, meaning it does not inherently contain nutrients like soil does.
This might slightly raise the overall cost, making it a bit more expensive than basic soil options. For optimal results with coco coir, maintain a pH level around 5.5 to 6.5 and take advantage of its excellent drainage and aeration properties.
Perlite: Enhancing Soil on a Budget
Perlite is a cost-effective option for enhancing soil aeration, promoting healthy root growth in cannabis plants. This lightweight additive is inexpensive and is often used in combination with soil to improve its structure. While perlite excels in improving soil aeration, it does not provide nutrients to the plants.
Additionally, perlite can be dusty, which may be an irritant to some growers. In terms of usage, perlite is typically mixed with soil at a ratio of 1:4 (perlite to soil). Its lightweight nature not only makes it easy to handle but also aids in better root development.
Vermiculite: The Water Retentive Additive
Vermiculite, a natural mineral that expands with heat, is known for its high water retention and nutrient retention capabilities. It helps in retaining moisture in the soil, which can be particularly beneficial during the germination stage or in drier climates.
Vermiculite also holds onto nutrients, releasing them slowly to the plants, which can enhance growth. However, it’s slightly more expensive than perlite and can lead to risks of over-watering and waterlogging if not managed properly. Vermiculite is often mixed with soil or used in germination mixes due to its beneficial properties.
In summary, each of these grow mediums – soil, coco coir, perlite, and vermiculite – offers unique benefits and potential drawbacks. The choice of medium depends on your specific needs, budget, and the environmental conditions of your grow space. By considering these factors, you can select the most suitable and cost-effective grow medium for your cannabis plants.
