Secret Jardin Dark Street DS90 R4.00 Grow Tent – 90 × 90 × 178cm

The Secret Jardin Dark Street DS90 R4.00 Grow Tent is the Version 4 model of Secret Jardin's popular 90cm Dark Street grow tent. Measuring 90 × 90 × 178cm, the DS90 R4.00 provides a compact, lightproof indoor growing environment with improved access, ventilation compatibility, and a strong steel supporting structure.

Designed specifically for indoor horticulture, the Dark Street DS90 Version 4 features a highly reflective M210D Mylar interior, 16mm Q195 steel poles, a large 270° opening, a removable water tray, and Secret Jardin's DF16 ventilation system.

With a 0.81m² growing footprint, the DS90 is an excellent choice for growers looking for a high-quality 90 × 90cm grow tent without requiring the space of a larger 120cm or 150cm setup.

Dark Street R4.00 – Version 4 Design

The R4.00 generation brings Secret Jardin's established Dark Street design together with practical features intended to make installation, ventilation and everyday grow-room access straightforward.

The DS90 R4.00 uses Secret Jardin's DF16 system for ventilation connections, a durable steel supporting structure and a large front opening for easy access to plants and equipment.

Its compact dimensions make it particularly well suited to smaller grow rooms, spare rooms and other indoor spaces where floor area is limited.

90 × 90 × 178cm Growing Space

The Secret Jardin DS90 measures 90cm wide × 90cm deep × 178cm high, providing a total growing footprint of approximately 0.81m² and an internal volume of approximately 1.4m³.

The square 90 × 90cm footprint works particularly well with appropriately sized LED grow lights, allowing light to be distributed efficiently across the canopy.

At 178cm high, there is also space for lighting, ventilation equipment and suitable clearance above the plants.

Highly Reflective M210D Mylar Interior

The Dark Street DS90 R4.00 uses M210D Mylar canvas with a highly reflective internal surface.

The reflective lining helps redirect light back toward the growing area, making better use of your grow light's output.

The tent is designed to be 100% lightproof and incorporates a double-flap zip system to help maintain the enclosed growing environment.

Large 270° Opening

One of the particularly useful features of the DS90 Version 4 is its large 270° opening.

The wide opening provides excellent access to the interior of the grow tent, making it easier to position plants, install equipment, water, prune and carry out routine maintenance.

This is particularly useful in a compact 90 × 90cm tent where unrestricted access can make managing the available growing area considerably easier.

Strong 16mm Steel Frame

The Secret Jardin Dark Street DS90 R4.00 uses 16mm Q195 chrome-plated steel poles to create a strong supporting structure.

Individual supporting poles are rated for loads of up to 10kg, while the tent has a maximum total hanging capacity of 20kg.

This provides suitable support for appropriately sized grow lights, extraction equipment and other lightweight grow-room accessories while remaining compact and easy to assemble.

DF16 Ventilation System

The DS90 R4.00 incorporates Secret Jardin's DF16 ventilation system.

The tent includes 2 × DF16 ducting flanges, configured for 125mm ducting, providing dedicated connections for your extraction and ventilation equipment.

This allows a suitable extraction fan, carbon filter and ducting system to be incorporated into the grow tent without having to cut or modify the tent material.

Removable Water Tray

A strong removable M210D Mylar water tray is included with the Secret Jardin DS90.

The tray helps protect the bottom of the grow tent from accidental water and nutrient spills while also making routine cleaning and maintenance easier.

Being removable means the tray can be taken out separately for cleaning when required.

Recommended Lighting & Extraction

Secret Jardin provides equipment recommendations based on the intended growing intensity.

For an intensive Level III setup, the manufacturer recommends approximately:

For a lower-intensity Level II setup, Secret Jardin recommends approximately 100W of LED lighting with around 150 m³/h extraction when using a filter.

These figures provide a useful starting point when selecting appropriately sized lighting and ventilation equipment for the DS90.
