Introduction
Contents
Embarking on the journey of growing cannabis can be both exciting and daunting. One of the most important decisions you’ll need to make is choosing between a hydroponic or soil-based nutrient delivery system. Both methods have their own unique advantages and disadvantages, and it’s important to consider each carefully before making the final decision. In this article, we’ll take an in-depth look at both systems, explore the different types of hydroponic and soil-based systems, compare their yield, growth rate, cost, and complexity, and help you decide which system is best suited for your needs.
What is Hydroponics?
Hydroponics is a method of growing plants without soil. Instead of soil, plants are grown in a nutrient-rich water solution. This method of growing has become increasingly popular in recent years, especially in the cannabis industry. With hydroponics, plants are able to grow faster and yield more compared to traditional soil-based methods.
One of the main advantages of hydroponics is that it allows growers to have greater control over the nutrient intake of their plants. This means that plants can be given exactly the right amount of nutrients to encourage healthy growth and higher yields. Additionally, hydroponic systems use less water than soil-based systems, making them more efficient and environmentally-friendly.
However, there are also some disadvantages to using hydroponics. One of the main downsides is that they can be more expensive and complex to set up compared to soil-based systems. Additionally, hydroponic systems require more maintenance and can be less forgiving of mistakes compared to soil-based systems.
Below is a table summarizing the pros and cons of hydroponic systems for cannabis cultivation:
| Pros | Cons |
|---|---|
| Allows greater control over nutrient intake | Higher initial set-up cost |
| Uses less water than soil-based systems | Can be more complex to set up |
| Faster plant growth and higher yields | Requires more maintenance |
| More environmentally-friendly | Less forgiving of mistakes |
Whether or not to use hydroponic systems is an important decision for cannabis growers. In the next sections, we will explore some of the different types of hydroponic systems as well as soil-based systems to help growers make an informed decision.
What is Soil-Based Nutrient Delivery System?
Soil-based nutrient delivery systems are the more traditional method of growing plants, where a plant is planted directly into the soil. The soil itself acts as a natural source of nutrients for the plant. This method is a more hands-off and natural approach to growing cannabis. However, it is important to note that not all soils are created equal and some may lack the necessary nutrients for optimal plant growth. This is where fertilizers come in.
Fertilizers are used to supplement the soil’s nutrient content, which can vary depending on the region or location of the grow. There are two main types of fertilizers: organic and synthetic. Organic fertilizers are made from organic matter, such as decomposed plant and animal material, and release nutrients slowly over time. Synthetic fertilizers, on the other hand, are made from chemical compounds and deliver nutrients more quickly, but can have negative effects on the environment if overused.
Soil-based nutrient delivery systems have some pros and cons:
| Pros | Cons |
|---|---|
| Natural source of nutrients | Soil quality can vary, affecting plant growth |
| Potential for greater flavor in cannabis due to the soil’s influence | Requires more effort in terms of plant maintenance and soil testing |
| Organic fertilizers can promote healthy microbial activity in the soil | Slow nutrient release may not provide sufficient nutrients for fast-growing cannabis strains |
Soil-based nutrient delivery systems can be a good option for those who prefer a more natural and hands-on approach to growing cannabis. However, it does require more effort in terms of soil testing and plant maintenance. Additionally, the quality of the soil can have a big impact on plant growth, so it is important to choose the right soil and fertilizers to ensure the best results. For those who are environmentally conscious, choosing organic fertilizers can also help promote healthy microbial activity in the soil and reduce the negative impact of synthetic fertilizers on the environment.
Hydroponics
When it comes to cultivating cannabis, one of the most innovative and highly-regarded methods is hydroponics. This system utilizes a nutrient solution to feed the plants instead of traditional soil. With hydroponic systems, plant roots sit in a solution of water and carefully portioned nutrients, which are delivered directly to the roots. This allows for precise control of the nutrient uptake and delivery, as well as faster and more abundant growth. However, since differences exist between synthetic and organic inputs, deciding between hydroponics or soil-based systems requires considering all relevant factors.

Pros
When it comes to Hydroponic systems, there are several pros that make them a viable option for cannabis cultivation. Here are some of the advantages:
| Advantages | Explanation |
|---|---|
| Increased Yield | With hydroponics, plants are given the exact amount of water and nutrients they need, resulting in faster and stronger growth. This often leads to higher yields compared to soil-based systems. |
| Water Conservation | Hydroponic systems use up to 90% less water compared to traditional soil-based systems. This is because the water is recycled and reused, resulting in less waste. |
| No Soil Needed | Since hydroponic systems use water and nutrient solutions instead of soil, there is no need for soil, which can lead to savings in terms of space and cost. |
| Control Over Nutrient Delivery | In soil-based systems, it can be difficult to ensure that plants are receiving the right balance of nutrients. With hydroponics, however, the grower has complete control over the nutrient delivery, resulting in healthier, more robust plants. |
| Less Chance of Soil-Borne Diseases | Soil can carry a variety of pests and diseases that can harm plants. In hydroponics, there is no soil, so the chance of soil-borne diseases affecting the plants is greatly reduced. |
These are just a few of the many advantages of using hydroponic systems for cannabis cultivation. However, it’s important to consider the potential cons as well before making a decision.
Cons
While hydroponic systems have their advantages, there are also several drawbacks that growers should consider. These include:
- More upfront costs: Setting up a hydroponic system can cost more initially as it requires specialized equipment such as pumps, timers, and grow lights.
- Higher electricity costs: Hydroponic systems rely heavily on artificial lighting which can lead to higher electricity bills.
- Higher risk of equipment failure: Due to the complexity of hydroponic systems, there is a greater risk of equipment failure which can be costly and time-consuming to fix.
- Potential for nutrient imbalances: While hydroponic systems are designed to provide precise nutrient delivery, it can be difficult to achieve balance and avoid nutrient deficiencies or toxicities.
- Increased responsibility: Hydroponic systems require more maintenance and monitoring than traditional soil-based systems, which might not be ideal for growers who have limited time or resources.
Despite these challenges, many growers still choose to leverage hydroponics due to their potential for higher yields, faster growth rates, and greater control over growing conditions.
Types of Hydroponic Systems
Hydroponics is a method of growing cannabis without soil, using water and nutrient solutions to deliver essential minerals and nutrients directly to the plant’s roots. There are several different types of hydroponic systems that offer growers different levels of control, efficiency, and complexity.
Deep Water Culture (DWC)
This is one of the easiest and most common types of hydroponic systems. It involves suspending the plants’ roots in nutrient-rich water using a platform or net. This allows the roots to absorb water and nutrients while also providing ample oxygen. DWC systems require constant monitoring of pH levels and nutrient levels to ensure optimal growth.
Drip System
A drip hydroponic system involves dripping nutrient solution onto the base of each plant through tubing or drippers. This system is relatively simple to set up and allows growers a high degree of control over nutrient delivery. The drip system can operate on a timer, which means growers don’t need to constantly monitor their plants’ progress.
Flood and Drain System
This hydroponic system involves flooding the growing medium, usually a tray filled with stones, with nutrient-rich water at regular intervals. The system drains the nutrient solution back into a reservoir through a tube, ensuring the roots have enough oxygen to thrive. This cycle repeats every few hours or so, ensuring the roots don’t become waterlogged.
Nutrient Film Technique (NFT)
An NFT system works by flowing a thin film of nutrient solution over a sloping channel, which supports the plants’ roots. The roots absorb the necessary minerals and nutrients as they grow. NFT systems are relatively cheap to set up and maintain, but they require regular monitoring to ensure a steady flow of water.
AeroPonics
AeroPonics involves suspending the plants’ roots in a mist of nutrient-rich water using a platform or net. This system allows growers to deliver nutrients and oxygen in a precise and controlled manner. AeroPonics is a relatively expensive and complex system to set up, but it can offer higher yields than other hydroponic systems.
Each of these hydroponic systems has its own advantages and disadvantages, and choosing the right system for your cannabis cultivation depends on your preferences, resources, and goals. The following section will go into further detail on the pros and cons of hydroponic systems as well as soil-based nutrient delivery systems.
