When it comes to cannabis cultivation, there are a variety of methods available for growers to consider. Two of the most popular techniques are growing in soil and hydroponics. Each method offers unique benefits and challenges, and understanding the differences between them can help you make an informed decision on how to grow your cannabis plants. In this blog, we’ll explore both soil and hydroponic growing methods, comparing their pros and cons, yields, and best practices, to help you determine which is best suited for your needs.
1. Introduction
Cannabis cultivation has come a long way from traditional outdoor growing methods. As demand for cannabis increases, growers have looked for ways to enhance yields, improve quality, and optimize the growing process. While soil has long been the go-to medium for growing cannabis, hydroponics has gained popularity for its ability to deliver faster growth and higher yields. Each method has its own set of advantages, and choosing between growing soil vs hydroponics depends on factors like experience level, budget, space, and the type of cannabis you want to grow.
2. What is Soil Growing?
Explanation of Traditional Soil Cultivation
Soil growing is the most natural method of cannabis cultivation, and it’s often preferred by growers who want to cultivate cannabis in a more organic way. In this method, plants are grown directly in soil, which provides the necessary nutrients and support for root growth. The soil contains organic matter that naturally breaks down to release nutrients, which the cannabis plants then absorb.

Common Soil Types Used in Cannabis Growth
The most common types of soil used for cannabis cultivation are:
Loamy Soil: Ideal for cannabis, loamy soil has a good balance of sand, silt, and clay, providing excellent drainage and nutrient retention.
Coco Coir: Made from coconut husks, coco coir is often used as a soil amendment to improve drainage while retaining moisture.
Peat Moss: Often combined with other soil types, peat moss helps with moisture retention and aeration.
Organic vs Store-Bought Soil Mixes
Organic Soil: Organic soil is free of synthetic chemicals and is preferred by growers who want to cultivate cannabis naturally. It’s rich in beneficial microorganisms that help improve plant health and soil structure.
Store-Bought Mixes: These are pre-mixed soils available at garden centres and cannabis supply stores. They can be tailored for specific growth stages, like seedling, vegetative, or flowering phases, but may contain synthetic additives.
3. What is Hydroponics?
Hydroponics is a method of growing plants without soil, where the plant roots are suspended in a nutrient-rich water solution. This water-based system provides all the essential nutrients the plants need to grow. Hydroponic systems allow for more control over the growing environment, as nutrients and pH levels can be monitored and adjusted with precision.
Types of Hydroponic Systems
Deep Water Culture (DWC): In this system, plant roots are submerged in oxygenated nutrient-rich water, allowing the plants to absorb nutrients directly.
Ebb & Flow: Also known as flood and drain, this system involves periodically flooding the plant roots with nutrient solution before draining it away.
Nutrient Film Technique (NFT): In NFT, a thin film of nutrient-rich water is continuously circulated around the plant roots, providing nutrients while allowing for good oxygenation.
Aeroponics: A more advanced system, aeroponics involves suspending plant roots in the air and misting them with nutrient solution.
Nutrient Solutions and Water-Based Control
In hydroponics, the nutrients are delivered through a water solution, which eliminates the need for soil. The grower has full control over the pH and nutrient levels, which can be adjusted to ensure optimal plant health and growth. This method often leads to faster growth and higher yields compared to traditional soil cultivation.
4. Cannabis Growing Hydroponics vs Soil: Key Differences
The most significant difference between growing in soil vs hydroponics is the medium in which the cannabis plants are grown and the way nutrients are delivered.
Soil: Cannabis plants receive nutrients from the organic matter in the soil, which slowly breaks down to provide a steady supply. The growing environment is less controlled than in hydroponics, and soil can retain moisture, which can affect root health if not monitored properly.
Hydroponics: In hydroponic systems, nutrients are delivered directly to the plant roots through water. This provides a more efficient and controlled environment but requires careful monitoring of pH levels, nutrient concentration, and water quality.
5. Pros and Cons of Growing in Soil
Pros of Soil Growing
Organic, Earthy Flavours: Cannabis grown in soil often has richer, more natural flavours due to the diverse microbial life in the soil.
Lower Initial Setup Cost: Soil-growing systems typically have a lower startup cost, especially for smaller operations.
Easier for Beginners: Soil is a forgiving medium and can be more forgiving for novice growers.
Cons of Soil Growing
Risk of Pests and Soil-Borne Diseases: Soil can harbour pests, fungi, and diseases, which can affect plant health.
Slower Growth Rate: Soil-grown cannabis typically grows slower compared to hydroponic methods.
6. Pros and Cons of Hydroponic Growing
Pros of Hydroponics
Full Control Over Nutrients and pH: Hydroponic systems offer precise control over the nutrients and pH levels, which can lead to faster growth and more efficient nutrient uptake.
Faster Growth and Higher Yields: Since plants are directly supplied with nutrients, they often grow faster and produce higher yields than those grown in soil.
Space Efficiency: Hydroponic systems can be more space-efficient, particularly in smaller or indoor environments.
Cons of Hydroponics
Higher Setup and Maintenance Cost: Hydroponic systems require more complex equipment, and the initial setup cost can be higher than soil-based systems.
More Technical Knowledge Required: Hydroponics requires careful monitoring of water pH, nutrient levels, and system maintenance, making it more suited for experienced growers.
7. Yield Comparison: Hydroponics vs Soil for Cannabis
The yield comparison between hydroponics and soil depends largely on the grower’s experience and the conditions of the cultivation environment.
Quality vs Quantity: Hydroponics often results in higher yields and faster growth due to the direct delivery of nutrients. However, some people argue that soil-grown cannabis offers better flavour and aroma profiles due to the organic growing process.
Commercial vs Personal Use: Hydroponics is often the preferred method for commercial cannabis operations, as it allows for higher yields and more controlled growth. For personal use, soil growing is popular for its natural approach and cost-effectiveness.
8. Which is Better for You?
Factors to Consider
Experience Level: If you’re a beginner, soil may be the best starting point due to its ease of use. Hydroponics is better suited for experienced growers who are comfortable with more advanced techniques.
Budget: Hydroponic systems generally require a higher initial investment in equipment and maintenance, while soil-based setups are more affordable.
Space: Hydroponics is a great choice for smaller spaces as it allows for vertical growth and more efficient use of space.
Taste Preference: If you value organic flavours, soil-grown cannabis is likely your best choice. Hydroponics tends to produce faster growth but might lack the earthy complexity that organic cannabis offers.
Ideal Scenarios for Each Method
Soil: Ideal for smaller-scale, organic growers or those who prefer a more hands-off, natural approach.
Hydroponics: Best for commercial growers or those looking for faster growth, higher yields, and precise control over their growing environment.
