- Can we optimize the installation of the extractors and the airflow in the Dark Room 150 R4.00 for a LED SCROG system without creating hot spots or loss of efficiency?
To optimize the installation of the extractors and airflow in the Dark Room 150 R4.00 in a LED SCROG system, it is essential to fully utilize its ventilation devices and its great height (217 cm). Position the extractor at the top of the tent to remove the accumulated warm air under the ceiling, and place the fresh air inlets downwards to create a natural upward vertical flow.
The DUCTING FLANGES DF25, perfectly airtight, facilitate an efficient and leak-proof installation of Ø150 mm ducts, limiting air leaks and losses. Add internal oscillating fans to homogenize the air mixing above the SCROG canopy, which avoids hot spots.
Finally, choose an extractor capable of renewing the air 20 to 30 times per hour, suitable for the volume of 4.88 m³, to effectively evacuate the concentrated heat from the LEDs without compromising photosynthesis. Thanks to the reflective Mylar and the robustness of the tent, this configuration guarantees a well-ventilated environment without stagnant zones or loss of efficiency.
- For 150x150x217, is the built-in ventilation with ducting flange sufficient or is an additional extractor recommended?
For the tent Dunkler Raum 150 x 150 x 217 cm R4,00, the built-in ventilation with the ducting flanges provides adequate basic aeration for moderate cultivation (levels I and II).
However, if you are considering intensive cultivation with powerful lighting, it is highly recommended to add an additional extractor. This ensures better control of temperature, humidity, and optimal air renewal under more demanding conditions.
In summary: the built-in ventilation is sufficient for beginner or moderate use, but for optimal performance and advanced cultivation, a supplementary extractor is advised.
- What is the maximum extraction flow rate supported by the flange provided with the Dark Room 150x150x217 R4.00?
The flange provided with the Dark Room 150x150x217 cm R4.00 supports a maximum extraction flow rate of 250 m³/h. This flow corresponds to the optimal capacity with a duct diameter of Ø150 mm, which is the size of the included flange.

- What is the average lifespan of the compatible carbon filter with this box to limit odors without affecting ventilation?
The average lifespan of a carbon filter compatible with the
Dark Room 150x150x217 cm R4.00 box is typically
12 to 18 months. This particularly applies to filters using high-quality activated carbon with good thickness, such as the CTC80 model suitable for this size.
To preserve this longevity, it is essential to use a pre-filter that is changed regularly (approximately every two months), maintain an ambient humidity of less than 65%, and avoid exposure to smoke, excessive dust, or water. Additionally, the maximum capacity in m³/h of the filter should not be exceeded to ensure effective filtration without disrupting ventilation.
Beyond this period, efficiency decreases and it becomes necessary to replace the filter to maintain a good management of odors without compromising airflow.
- What is the integration capacity of variable ventilation systems in the Dark Room 150 to optimize lighting conditions under LED in SCROG or LST?
The Dark Room 150x150x217 cm R4.00 from Secret Jardin offers excellent integration capacity for variable ventilation systems, ideal for optimizing conditions under LED lighting in SCROG or LST. It is equipped with a Ducting Flange system that allows precise adjustment of the airflow according to your needs. Its modularity enables you to freely position the extraction and cable passages, ensuring effective airflow circulation to prevent heat and stagnant humidity.
Its great height (217 cm) and generous surface area (150 x 150 cm) facilitate the installation of suitable equipment, while the 360° opening provides easy access to adjust and maintain your ventilation. Thus, this tent perfectly supports SCROG and LST methods by ensuring a stable and healthy environment for your plants under LED.
