The 5 best cannabis hydro systems in comparison: Which system maximizes your yield?
If you are looking for the perfect hydro system for your cannabis cultivation, you have come to the right place. We have examined the top 5 systems to make your decision easier and maximize your yield.
1. Deep Water Culture (DWC)
The DWC system is a classic among hydro setups. Here, the roots of your plants hang directly in a nutrient-rich solution. The big advantage: extremely fast growth thanks to the optimal supply. However, it also requires precise monitoring of the water values.
2. Nutrient Film Technique (NFT)
With the NFT method, a thin film of nutrient solution flows over the roots. This system is particularly space-saving and is ideal for larger systems. It offers an excellent oxygen supply, but can become problematic in the event of a power outage.
3. Ebb and Flow
This system regularly floods the root system and then lets it dry again. It is very versatile and forgives small mistakes. Perfect for beginners who still want to achieve good yields.
4. Aeroponics
In aeroponics, the roots are sprayed with a fine mist of nutrients. This method enables the fastest growth and the highest yields, but is technically demanding and more suitable for experienced growers.
5. Drip system
With the drip system, the nutrient solution is dripped slowly and continuously onto the substrate. It is very reliable and is well suited for larger plants. However, if the settings are incorrect, blockages can occur.
| system | Advantages | Disadvantages | Earnings potential |
|---|---|---|---|
| DWC | Rapid growth | Close monitoring required | High |
| NFT | Space-saving | Vulnerable to power outages | Medium to High |
| Ebb and Flow | Beginner friendly | Less efficient than other systems | Medium |
| Aeroponics | Highest yields | Technically demanding | Very high |
| Drip system | Reliable | Possible blockages | High |
Choosing the right system depends on your experience, available space, and yield goals. For beginners, we recommend the Ebb and Flow system, while experienced growers can achieve top yields with Aeroponics. Keep in mind that each system has its own advantages and disadvantages. Experiment and find out which one works best for you and your cannabis plants.
Optimize nutrient supply: How to increase the potency of your plants by up to 30%
Optimal nutrition is the key to strong, high-yielding cannabis plants. With the right techniques and a little knowledge, you can increase the potency of your plants by up to 30%. Let's take a closer look at how you can achieve this.
The basics of nutrient supply
Before we dive into the finer points, it's important to understand the basics. Cannabis requires a balanced mix of macro and micronutrients. The main players are:
- Nitrogen (N)
- Phosphorus (P)
- Potassium (K)
These form the basis of any good nutritional solution. But it is the finer adjustments and additions that can make the difference.
pH value: The often overlooked game changer
The pH of your nutrient solution is crucial for nutrient uptake. For hydro systems, the optimal range is between 5.5 and 6.5. A pH that is too high or too low can block nutrient uptake, no matter how high quality your nutrients are. Invest in a good pH meter and adjust the value regularly.
Keep an eye on electrolytic conductivity (EC)
The EC provides information about the concentration of nutrients in your solution. Too many nutrients can lead to burns, too few can lead to deficiency symptoms. Here is a rough guide:
| Growth phase | Recommended EC value |
|---|---|
| Seedlings | 0.8 - 1.0 |
| Vegetative phase | 1.2 - 1.6 |
| Flowering phase | 1.6 - 2.4 |
Promote microbial life
Microbial life can also play an important role in hydro systems. Probiotic additives can improve nutrient absorption and strengthen the plant's immune system. Products containing Bacillus bacteria or mycorrhizal fungi have proven to be particularly effective.
Adaptation to growth phases
Your plants have different needs at different stages of growth. During the vegetative phase, they require more nitrogen, while during the flowering phase, the need for phosphorus and potassium increases. Adjust your nutrient solution accordingly to reach its full potential.
The boost from additives
Special additives can increase the performance of your plants even further:
- Silicon: Strengthens cell walls and increases stress resistance
- Fulvic acid: Improves nutrient absorption
- Enzymes: Accelerate the decomposition of organic matter
With the right combination of these techniques, you can significantly increase the potency and yield of your cannabis plants. Experiment carefully and monitor your plants closely. Any changes should be made gradually to avoid stress. With a little patience and attention, you will soon be able to reap the benefits of your optimized nutrient supply.
