Secret Jardin Dark Street V4 120 Wide 4' x 2' x 6' Hydroponic Grow Tent

The Secret Jardin Dark Street V4 120 Wide is a premium compact grow tent designed for gardeners who want the efficiency of a 4' x 2' footprint with easier plant access, strong light control, and professional grade construction.

Its wide rectangular format provides approximately 8 square feet of grow space while keeping the enclosure only about 24 inches deep. That makes it especially practical for placing against walls, inside narrow rooms, along hallways, or anywhere a deeper square tent would take up too much floor space.

• Grow Space: Approximately 8 sq. ft.
• Reflectivity: 95% Reflective Mylar
• Frame: 16 mm Q195 Steel
• Warranty: 1 Year Product Warranty

The DS120 Wide measures approximately 4 feet wide by 2 feet deep by 6 feet high, providing enough vertical clearance for full cycle plant growth while remaining compact enough for residential environments.

The enclosure is built from Secret Jardin 190M fabric, which is designed to provide strong light blocking performance while maintaining the durability required for repeated setup, access, and equipment changes.

Inside, a 95% reflective Mylar lining helps redirect light toward the plant canopy. This increases the usefulness of your installed lighting by reducing light absorption through the walls and helping distribute illumination more evenly across the growing area.

The frame uses 16 mm Q195 steel poles paired with reinforced polypropylene corner connectors. This combination provides a rigid internal structure while maintaining straightforward tool free assembly.

Secret Jardin also includes a Space Booster system that helps prevent the tent walls from pulling inward when strong exhaust creates negative pressure. The Space Booster can also support the included WebIT trellis net, making canopy management easier across the wide footprint.

The rectangular design is particularly useful for gardeners who want better access to plants without reaching deep into the back of a square enclosure. The shallow 2 foot depth means most plants remain within comfortable reach during watering, pruning, training, inspection, and harvesting.

The DS120 Wide also includes a dedicated Water Tray 120W to help protect the bottom of the enclosure from spills, runoff, soil, and general gardening debris.

Secret Jardin supplies several installation and organization accessories with the tent, including StrapIT filter straps, HookIT lighting hooks, CableIT cable clips, PocketIT tool storage, a Space Booster, WebIT support, and PatchIT repair material.

The combination of 190M fabric, highly reflective Mylar, steel framing, integrated organization accessories, trellis support, and a shallow 4' x 2' footprint makes the Secret Jardin Dark Street V4 120 Wide an excellent option for compact full cycle indoor gardens.

Wide 4' x 2' Footprint

The DS120 Wide provides approximately 8 square feet of usable floor area. Its rectangular layout works especially well for narrow grow rooms, spare bedrooms, closets, hallway style spaces, wall mounted setups, rectangular LED fixtures, multiple smaller containers, and trellis based gardens. The 2 foot depth also makes reaching the rear of the canopy significantly easier than with deeper square tents.

Approximately 8 Square Feet of Grow Space

The 4' x 2' floor plan provides approximately 8 square feet of growing area. The supplied product information describes the enclosure as suitable for up to approximately 3 plants. Actual plant capacity depends on container size, plant size, training style, lighting coverage, airflow requirements, and equipment placement.

6 Foot Height

The tent measures approximately 6 feet tall. This provides vertical space for mature plants, containers, hanging lights, carbon filters, exhaust fans, ducting, environmental sensors, and trellis systems. Growers should account for container height, mature canopy height, fixture thickness, and recommended light distance when planning the setup.

190M Light Proof Fabric

Secret Jardin uses 190M fabric for the Dark Street V4 enclosure. The material is designed to provide strong light blocking performance, durable enclosure walls, long term resistance to normal wear, support around doors and openings, and reliable environmental separation. The thicker fabric also helps make the enclosure easier to handle during repeated opening, closing, and equipment changes.

95% Reflective Mylar Interior

The interior is lined with approximately 95% reflective Mylar. This helps redirect light toward the canopy, reduce light absorption through the walls, improve side illumination, reduce dim areas, improve lighting efficiency, and support more even canopy coverage.

Designed for Efficient Lighting

The reflective interior makes better use of rectangular LED fixtures commonly designed for 4' x 2' coverage. When selecting lighting, consider actual fixture dimensions, hanging height, coverage pattern, heat output, canopy size, and available vertical clearance.

Q195 Steel Frame

The DS120 Wide uses 16 mm Q195 steel poles. The steel frame provides strong structural support, stable equipment mounting, reliable frame alignment, better resistance to bending than lightweight plastic structures, and long term durability.

Reinforced Polypropylene Corners

Polypropylene corner connectors secure the steel frame sections. These connectors help maintain frame alignment, simplify assembly, reduce movement, support repeated setup and breakdown, and keep the enclosure lightweight enough for home use.

Tool Free Assembly

The frame is designed to assemble without specialized tools. A typical setup involves connecting the lower frame, installing the vertical poles, connecting the upper frame, installing the reinforced corners, positioning the tent fabric, installing the Water Tray, adding the Space Booster, and installing lighting and ventilation.

Space Booster Included

The included Space Booster helps prevent the side walls from collapsing inward when strong exhaust creates negative pressure. This can help preserve interior growing space, keep walls away from plants, maintain canopy width, improve internal organization, and support the WebIT trellis system.

WebIT Trellis Support

The included WebIT system provides trellis support for canopy management. This can help gardeners spread branches evenly, control canopy height, improve light exposure, support heavy growth, and maintain an organized rectangular canopy.

Shallow 24 Inch Depth

One of the biggest practical advantages of the DS120 Wide is its shallow depth. At approximately 24 inches deep, the tent makes it easier to reach rear plants, containers, trellis points, irrigation lines, sensors, circulation fans, and fallen leaves and debris.

Improved Plant Access

The wide footprint reduces the need to reach across a deep enclosure. This can make routine tasks easier, including watering, pruning, training, defoliation, pest inspection, trellis adjustment, and harvesting.

DF16 Ducting Flange Compatibility

The Dark Street V4 platform uses Secret Jardin DF16 ducting flange technology for intake and exhaust management. This system is designed to simplify ventilation routing while maintaining a clean and organized enclosure. It can support exhaust ducting, intake ducting, carbon filter connections, inline fans, and environmental ventilation systems.

Ventilation Ready

Proper ventilation helps manage heat, humidity, fresh air exchange, negative pressure, internal circulation, and odor control when paired with compatible filtration.

Water Tray 120W Included

The supplied Water Tray 120W helps protect the bottom of the enclosure from irrigation runoff, water spills, soil, nutrient solution, plant debris, and general maintenance mess. The removable tray also makes routine cleaning easier.

HookIT Lighting Hooks

The included HookIT system provides hanging support for lighting equipment. These hooks help simplify fixture installation, keep lighting organized, make height adjustment easier, and reduce the need for improvised hanging hardware.

StrapIT Filter Straps

A pair of StrapIT straps is included for supporting filtration equipment. These can be used to help suspend compatible carbon filters, ventilation components, and lightweight environmental equipment. Always confirm the frame and accessory load limits before hanging heavy equipment.

CableIT Cable Clips

The DS120 Wide includes 15 CableIT clips. These clips help organize lighting cables, fan cords, sensor wires, controller cables, and trellis lines. Cleaner cable routing can improve access and reduce clutter inside the enclosure.

PocketIT Tool Storage

The included PocketIT pouch provides adjustable height storage for frequently used items. It can help keep small equipment organized, including scissors, pH meters, EC meters, thermometers, plant ties, and measuring tools.

PatchIT Repair Accessory

The included PatchIT accessory can be used for minor tent repairs or for replacing a DF16 opening when configuration changes are needed. This gives growers additional flexibility when modifying the ventilation layout.

Full Cycle Growing

The DS120 Wide is designed for more than propagation. Its approximately 6 foot height supports full cycle plant development from early growth through maturity when paired with appropriately sized equipment.

Designed for Plants Approximately 50 cm to 150 cm Tall

Secret Jardin describes the Dark Street range as being designed for plants measuring approximately 50 cm to 150 cm tall. Actual usable plant height depends on container height, lighting system, hanging hardware, required fixture clearance, ventilation equipment, and training style.

Compact Professional Layout

The tent combines features normally found in larger systems while maintaining a compact footprint. These include steel framing, reflective Mylar, light proof fabric, trellis support, cable management, filter straps, lighting hooks, repair accessories, and a removable water tray.
