Secret Jardin Dark Propagator V4 90 3' x 2' x 3'4" Hydroponic Grow Tent

The Secret Jardin Dark Propagator V4 90 is a compact propagation tent designed specifically for seedlings, cuttings, mother plants, and early stage plant development where precise environmental control matters more than vertical growing height.

With a footprint of approximately 3 feet wide by 2 feet deep and an overall height of roughly 3 feet 4 inches, the DP90 provides approximately 6 square feet of dedicated propagation space while fitting easily into closets, corners, nursery rooms, garages, and other compact indoor areas.

• Propagation Space: Approximately 6 sq. ft.
• Reflectivity: 95% Hammered Mylar
• Tray Capacity: Up to 2 x 77 Cell Trays
• Warranty: 1 Year Product Warranty

The enclosure is designed as a specialized propagation station rather than a conventional full height grow tent. Its lower profile makes it ideal for propagation trays, young plants, cuttings, mother stock, and compact lighting systems.

The interior is lined with highly reflective hammered Mylar rated at approximately 95% reflectivity. The textured reflective finish helps scatter light across propagation trays and young plants, improving light distribution from lower wattage propagation fixtures.

This is especially useful in a nursery environment where even, gentle lighting is more important than intense overhead penetration.

The enclosure uses waterproof and lightproof fabric designed to create a controlled environment for humidity, airflow, lighting, and early stage plant development.

The supplied manufacturer information references both 190D exterior fabric and 210D reflective Mylar construction. The important functional point is that the tent is built for waterproof, light resistant propagation use with approximately 95% reflective hammered interior material.

The DP90 also incorporates a transverse venting window system. These ventilation openings help improve airflow across propagation trays while avoiding the concentrated air movement that can dry out sensitive cuttings.

The compact dimensions make the tent particularly useful for growers who want to separate propagation from their main production area. Keeping seedlings and clones in their own environment makes it easier to manage humidity, temperature, lighting intensity, and airflow independently from mature plants.

The enclosure is compatible with up to two 77 cell rockwool cube trays according to the supplied manufacturer information, making it useful for organized propagation workflows.

An optional Hydro Tray measuring approximately 40 x 60 x 2.5 cm is also available for compatible nursery setups.

The frame uses rigid equipment support tubes designed to maintain the enclosure shape and provide support for lightweight propagation lighting and accessories.

The material is washable on both the inside and outside, helping growers maintain a cleaner nursery environment between propagation cycles.

A removable water tray is included to help protect the base of the enclosure from spills, runoff, humidity dome overflow, and general propagation mess.

The combination of a compact 3' x 2' footprint, approximately 95% reflective hammered Mylar, waterproof construction, transverse ventilation, equipment support tubes, and washable surfaces makes the Secret Jardin Dark Propagator V4 90 a purpose built solution for propagation and early stage indoor gardening.

Dedicated Propagation Space

The DP90 provides approximately 6 square feet of dedicated nursery space. It is designed for seedlings, cuttings, clones, mother plants, early vegetative growth, propagation trays, rockwool cubes, and nursery lighting.

Compact 3' x 2' Footprint

The enclosure measures approximately 3 feet wide, 2 feet deep, and 3 feet 4 inches high. This compact format fits well in closets, small grow rooms, spare rooms, garages, nursery corners, utility spaces, and under larger environmental systems.

Approximately 6 Square Feet of Floor Area

The 3' x 2' footprint provides roughly 6 square feet of growing space. This is enough room for multiple propagation trays, seedling containers, mother plants, cloning systems, small nursery fans, and compact environmental controls.

Designed for Seedlings and Cuttings

The DP90 is purpose built for early plant stages where environmental stability is critical. Young plants often require higher humidity, lower light intensity, gentle airflow, stable temperatures, consistent moisture, and protected root development. Separating these plants from a mature canopy makes those conditions easier to control.

Mother Plant Compatible

The manufacturer describes the DP90 as suitable for mother plants as part of an all in one propagation station. Its compact height is best suited for short mother plants, regularly pruned stock plants, compact genetics, and controlled nursery systems.

Up to Two 77 Cell Rockwool Trays

The supplied manufacturer information states that the DP90 can accommodate up to two 77 cell rockwool cube trays. This makes it suitable for organized propagation programs requiring substantial clone or seedling capacity within a small footprint.

Optional Hydro Tray Compatible

An optional Hydro Tray measuring approximately 40 x 60 x 2.5 cm is available. This can help organize propagation cubes, seedling containers, drainage, irrigation runoff, and nursery trays.

95% Reflective Hammered Mylar

The interior uses hammered reflective Mylar rated at approximately 95% reflectivity. This helps return light toward young plants, improve light distribution, reduce wasted light, improve side illumination, reduce dark areas, and make better use of lower wattage propagation lighting.

Hammered Reflective Texture

The textured interior helps scatter light across multiple angles. This is particularly useful with LED propagation bars, fluorescent fixtures, low wattage nursery lights, multi tray layouts, and short plant canopies.

Designed for Low Intensity Lighting

Propagation tents generally do not require the same lighting intensity as full cycle flowering tents. The reflective interior helps improve the effectiveness of propagation LEDs, clone lighting, seedling bars, compact fixtures, and low wattage nursery systems.

Waterproof Construction

The enclosure is designed to resist water associated with propagation environments. This is useful for high humidity, watering spills, humidity dome overflow, irrigation runoff, nursery trays, and routine cleaning.

Lightproof Construction

The DP90 is designed to create a controlled lighting environment. Light resistant construction helps maintain scheduled lighting, reduce external light intrusion, prevent unnecessary light spill, and separate propagation from surrounding rooms.

Transverse Venting Window System

The DP90 incorporates transverse ventilation windows. This design helps move air across the propagation area rather than concentrating airflow from one direction. Benefits include more even air movement, reduced stagnant humidity, lower risk of localized dry spots, improved temperature consistency, and better nursery airflow.

Gentle Airflow for Sensitive Cuttings

Young cuttings can be damaged by excessive direct airflow. The transverse venting layout helps create broader, gentler circulation across the enclosure. This can help reduce dry leaf edges, rapid moisture loss, uneven humidity, and stagnant corners.

Rigid Equipment Support Tubes

The enclosure uses strong equipment tubes designed to maintain structure and support compatible nursery equipment. These can help support lightweight propagation lights, small circulation equipment, cables, and monitoring sensors. Always confirm equipment weight before hanging anything from the frame.

Stable Compact Frame

The rigid frame helps maintain the shape of the low profile enclosure. This supports easier tray placement, better equipment alignment, consistent interior dimensions, and cleaner cable routing.

Removable Water Tray

A removable water tray is included. It helps protect the base of the enclosure from water spills, irrigation runoff, humidity dome overflow, growing media, plant debris, and nutrient solution.

Washable Interior

The interior material is washable. This helps growers remove rooting solution residue, water spots, dust, growing media, plant debris, and mineral buildup.

Washable Exterior

The exterior can also be cleaned between nursery cycles. Regular cleaning helps maintain a cleaner propagation area and reduces accumulated dust and debris around the enclosure.

Easy Assembly

The DP90 is designed for quick and straightforward assembly. A typical setup involves connecting the frame sections, installing rigid support tubes, positioning the fabric enclosure, installing the water tray, positioning propagation lighting, setting up ventilation, and adding trays and plants.

Compact Nursery Layout

The low profile design works especially well for bench style nursery setups, closet propagation, dedicated clone rooms, seedling stations, small mother plant zones, and multi stage indoor gardens.

Separate Propagation Environment

One of the biggest benefits of the DP90 is the ability to separate young plants from mature plants. This allows independent control of humidity, lighting intensity, airflow, temperature, watering frequency, and photoperiod.

Humidity Management

Propagation environments often require higher humidity than mature plants. A dedicated enclosure makes it easier to maintain conditions appropriate for rooting cuttings, germinating seedlings, and newly transplanted plants.

Airflow Management

Gentle air movement helps prevent stagnant conditions while avoiding excessive drying. When adding circulation equipment: use low fan speeds, avoid direct airflow on fresh cuttings, keep vents unobstructed, monitor humidity, and adjust airflow gradually.

Lighting Setup

When installing propagation lighting: choose a fixture appropriate for approximately 3' x 2' coverage, use lower intensity lighting suitable for seedlings and cuttings, keep the fixture evenly centered, maintain the manufacturer’s recommended distance, monitor young plants for light stress, and adjust fixture height as growth develops.

Propagation Lighting

For seedlings and cuttings: use gentle, evenly distributed lighting, avoid excessive intensity, maintain consistent photoperiods, monitor leaf color and stretching, adjust fixture height as necessary, and keep electrical components dry.

Nursery Airflow

Propagation airflow should be sufficient to prevent stagnation without rapidly drying plant material. Good practices include low speed circulation, broad airflow patterns, monitoring humidity, avoiding direct fan blasts, and keeping vent openings clear.

Humidity Control

Young cuttings may require elevated humidity during initial rooting. Monitor relative humidity, leaf condition, dome condensation, root development, and surface moisture. Gradually reduce humidity as plants establish stronger roots.

Plant Arrangement

The 3' x 2' interior can support up to two 77 cell rockwool trays, seedling trays, clone trays, compact mother plants, propagation domes, and small nursery containers. Leave enough space for air movement, watering, inspection, tray removal, and electrical safety.
