Which filter size do you need? Simple calculation for your grow box
The right filter size is crucial for effective and odor-free cannabis cultivation. Incorrect sizing can lead to inadequate odor filtration or unnecessarily high costs. Here you can find out how to calculate the optimal filter size for your grow box.
Basics of filter size calculation
The size of your filter depends mainly on two factors: the volume of your grow box and the air exchange rate. As a rule of thumb, the air in your grow box should be completely exchanged at least every two minutes.
Step-by-step calculation
- Calculate the volume of your grow box in cubic meters (length x width x height).
- Multiply the volume by 30 to get the recommended hourly air change rate.
- The result is the amount of air in m³/h that your filter has to handle.
Example: A grow box measuring 1m x 1m x 2m has a volume of 2m³. Multiplied by 30, this results in an air flow of 60m³/h.
Additional factors
In addition to pure volume, you should also consider the following aspects:
- Number and size of plants
- Light intensity (more light = more heat = higher air exchange required)
- Humidity in the room
- Outside temperature
In practice, it is advisable to choose a filter that has a slightly higher capacity than your calculations show. This gives you room for adjustments and ensures effective odor neutralization even under changing conditions.
Filter size vs. fan power
Note that the power of your fan should match the capacity of the filter. A fan that is too powerful can overwhelm the filter performance, while a fan that is too weak will not utilize the full capacity of the filter.
| Growbox volume | Recommended filter capacity | Suitable filter sizes |
|---|---|---|
| Up to 1m³ | 30-60 m³/h | 100mm / 4 inch |
| 1-2m³ | 60-120 m³/h | 125mm / 5 inch |
| 2-4m³ | 120-240 m³/h | 150mm / 6 inch |
| 4-8m³ | 240-480 m³/h | 200mm / 8 inch |
Remember that this table is only a rough guide. Your specific situation may vary, especially if you have many plants or high light intensity.
Conclusion
The right filter size is an important building block for your successful and discreet cannabis cultivation. Using the calculation method described above and the additional considerations, you can choose a filter that is the perfect fit for your grow box. Invest the time in a careful selection - it will pay off with odor-free and efficient cultivation.
