The use of an air extractor is essential when growing plants indoors in a grow tent. Without proper ventilation, plants can quickly suffocate from lack of oxygen.
As the grow tent is an enclosed environment, plants and lighting sources generate heat. It is therefore essential to have an air extractor to renew the air inside the grow room.
The importance of ventilation in indoor cultivation
Air flow in indoor cultivation is controlled by the intractor, which draws in fresh air from outside, and the extractor, which exhausts impure air. Both are essential for healthy plant growth.
Outside, air plays a crucial role in plant development. They suck in and release warm air (CO² + O²) and need to breathe fresh air every day. Wind also stimulates their leaves.
When growing indoors, plants also need to capture CO² from the air. Ideally, the extractor should renew the air in the grow room at least 2-3 times an hour, replacing it in less than 2 minutes.
The extractor is therefore an essential element in ensuring adequate ventilation in an indoor garden.
Optimizing for different types of lighting
When growing indoors, the heat generated by lamps can be a challenge. High-pressure bulbs (HPS) and mercury lamps (MH) are known to produce more heat than other types of lighting. Be sure to take this extra heat into account when choosing your air extractor and its ability to maintain optimal temperatures.
Ducts and their crucial role
Ducts are essential accessories for connecting your air extractor to the ventilation grilles in your growing space. Make sure you choose the right size sheaths, according to the diameter of your extractor and your aeration grids. Tight, well-fitting connections are necessary to avoid air leaks and maximize the efficiency of your ventilation system.
Air extractor selection and key factors
When choosing an air extractor, there are several factors to consider. The size of your growing space, the capacity of your grow tent and the type of lighting you use will all influence your ventilation needs.
Air extractors are generally measured in terms of air flow, expressed in cubic meters per hour (m³/h). We recommend choosing an extractor that can renew the air in your grow room at least two to three times an hour. This will ensure a sufficient supply of oxygen for your plants and help maintain appropriate CO² levels.
Extractor regulators, such as the GSEmodels, offer precis control over fan speed. They allow you to adjust the speed of your extractor to the specific needs of your plants. This can be particularly useful when you need to manage variations in temperature or humidity at different stages of growth.
Complementary equipment for successful cultivation
In addition to the air extractor, we recommend that you also install a fan in your growing space. Fans help maintain constant air circulation, prevent moisture build-up and strengthen plant stems through regular air movement. They can also promote better distribution of CO² in the grow room.
To reduce noise pollution associated with the use of air extractors, Growshops offers soundproof boxes. These boxes are designed to attenuate the noise emitted by the extractor, allowing you to enjoy a quieter growing environment.
