The stainless steel structure of the Dark Room 297 x 297 x 217 cm R4,00 is very robust, with 25 mm diameter tubes, ensuring excellent strength. It is specially designed to support heavy loads, particularly thanks to the integrated equipment bars that are intended to suspend both powerful lighting and imposing ventilation systems.
You can therefore easily install a heavy suspension system for lighting and ventilation without worry, the structure will easily support it, even under intensive use.
To optimize air circulation and limit heat in the Dark Room 297 x 297 x 217 cm R4.00 tent, it is advisable to use the two D160 mm connectors as follows:
This setup guarantees a perfect balance between extraction and fresh air intake, limiting heat while promoting a healthy and dynamic atmosphere for your crops.
The Dark Room 300 R4.00 uses 400D Mylar fabric with an advertised reflectivity of 95%, which corresponds to a theoretical light loss of 5% with each reflection. In real growing conditions, this value is slightly higher due to wear, dust, seams, and other components of the box. Thus, the effective light yield loss due to the fabric is generally between 10 and 15% after several reflections and with normal usage.
In summary, you can count on excellent reflectivity close to 95% in a new and well-maintained box, with slight performance degradation that remains controlled over time.
For a growing area of 150x150 cm in the Dark Room 297x297x217cm R4.00 tent, a LED power of about 960 W is optimal. This power allows for excellent yield while controlling electricity consumption.
To accompany this lighting, it is important to ensure effective ventilation: an extractor of about 295 m³/h and an internal fan of 148 m³/h will guarantee healthy air circulation, essential for maximizing growth while avoiding overheating and energy losses.
This configuration ensures a perfect balance between light performance and energy savings in your Dark Room.
The Dark Room 297 x 297 x 217 cm R4.00 from Secret Jardin is perfectly suited for beginners and for growing. Its large volume and robust structure allow for several devices to be installed and the configuration to be adjusted as the plants grow.
For the LEDs, installation is simple thanks to the solid bars of the tent and the mounting systems (hooks, adjustable straps) that make assembly easy, even for a novice.
Regarding odor control, with a well-sized ventilation system (extraction fan + carbon filter), the tent offers effective sealing, making odors almost nonexistent, even in this large volume.
The Dark Room 297 x 297 x 217 cm R4.00 from Secret Jardin has extraction sleeves of 305 mm, which is not directly compatible with a silent extractor of 200 mm. However, it is quite possible to use reducers or adapters to connect a 200 mm extractor and thus benefit from quieter operation, ideal for a discrete environment in an apartment.
The Dark Room 297x297x217cm R4.00 from Secret Jardin does not natively include a remote temperature and humidity monitoring system. However, its robust and modular design, with numerous extraction ports and access points, allows for easy installation of connected sensors for real-time control of your growing environment.
The stainless steel finish on the tent Dark Room 297 x 297 x 217 cm R4.00 – Secret Jardin Anzuchtkasten is a major asset for humidity management and longevity in intensive cultivation. This non-porous and corrosion-resistant material prevents rust formation and does not absorb moisture, thereby reducing the risks of mold and deterioration of the frame.
It also facilitates maintenance and disinfection, which are essential for maintaining a healthy and stable environment. In a demanding cultivation environment, this robustness ensures better durability of the tent against humidity fluctuations and the products used, guaranteeing a reliable investment in the long term.
To limit heat while maximizing yield in the Dark Room 297 x 297 x 217 cm R4,00 tent, the best ventilation relies on a precise balance between extraction and intake of fresh air.
Use the two opposite 160 mm connections: install a powerful extractor (500 to 800 m³/h depending on lamps and plant density) on one, and an intake fan on the other. This arrangement ensures effective cross circulation, quickly expelling accumulated heat.
Add internal oscillating fans to homogenize the air around the plants, avoiding hot spots and stabilizing temperature and humidity. The robust structure of this tent easily supports these powerful systems, essential for maintaining a dynamic and healthy environment.
The 400D Mylar fabric with high reflectivity promotes light but requires well-calibrated ventilation: this setup guarantees performance and thermal comfort for your indoor cultivation.
The Secret Jardin Dark Room tent 297x297x217 cm R4.00 offers a total interior height of 217 cm. Taking into account the standard installation of a hanging lamp and extractor, the usable net space available for cultivation generally ranges between 175 and 190 cm. This estimate corresponds to a reduction of approximately 20 to 40 cm due to equipment mounted overhead.
This height is perfectly suited for growing medium to large-sized plants, providing enough space for their development while ensuring effective ventilation and lighting.
The Dark Room 297x297x217 cm offers a growing area of about 9 m², perfect for plants between 50 and 150 cm in height. To maintain optimal air circulation and effective climate control, it is recommended to grow between 10 and 15 plants. This density ensures a good balance between development space, ventilation, and humidity control, essential for healthy growth.
Beyond that, air circulation can be compromised, making it more difficult to maintain an appropriate VPD and increasing risks related to humidity. Taking advantage of the integrated Ducting Flange system allows adjusting ventilation according to plant load and light power, but it remains wise not to overload the tent to ensure the best growing conditions.
A growing space of 150x150x217 cm is quite suitable for micro space cultivation, much more compact than the Dark Room 297x297x217 cm R4.00 which is intended for larger crops. This compact size allows for optimized lighting and ventilation with well-chosen equipment.
For effective air extraction, a ventilation system sized to the volume of the tent is necessary, with compact filters and a fan, ensuring good temperature and humidity management. Tents in this range include extraction ports compatible with efficient compact extractors.
In summary, a 150x150x217 cm tent, equipped with appropriate LED lighting and well-calibrated extraction, is an excellent solution for effective and well-controlled micro space cultivation.
The modular design of the Dark Room 297x297x217cm R4.00 allows for easy adjustment of ventilation according to the precise needs of the growth and flowering phases, promoting optimal air circulation and humidity control.
This modularity also offers a flexible interior layout, to organize the space according to the size of the plants: shelves or closely placed supports during growth, an open area for larger plants during flowering, thus maximizing light and facilitating work.
By simplifying rapid adjustments without additional equipment, this system helps maintain a stable microclimate, optimizing plant health while controlling energy consumption.
The Dark Room 297x297x217cm R4.00 from Secret Jardin does not have an integrated system for direct voice assistant control for ventilation, lighting, or automatic watering.
However, its robust structure and large extraction sleeves offer excellent hardware compatibility for adding external home automation systems. It is possible to integrate relays, sensors, and connected controllers (for example via Home Assistant) for personalized voice control of your equipment, but this requires specific installation and dedicated hardware, not provided with the tent.
This approach will allow you to automate and intelligently control your indoor growing environment while maintaining the flexibility offered by this quality growing box.
To perfectly manage ventilation in your Dark Room 297x297x217cm R4.00 and optimize the climate for multiple varieties, the key is to ensure homogeneous and adaptable air circulation.
Here is the ideal method:
By combining these elements, you ensure that each variety has a stable and healthy environment, promoting optimal development.
