Garden HighPro PROBOX MASTER 120 Grow Tent 120x120x200 cm – Professional 600D Grow Tent with 97% Mylar Reflection

The Garden HighPro PROBOX MASTER 120 Grow Tent (120x120x200 cm) is a professional indoor grow tent designed for growers who demand maximum stability, light utilization, and durability in a medium-sized indoor grow setup.

With an effective growing area of 1.44 m², this 120x120 grow tent offers the perfect balance of space, control, and efficiency. Thanks to the extra strong 600D nylon fabric, patented metal frame, and 97% premium Mylar reflection, the PROBOX MASTER 120 creates a completely light-tight, stable, and optimally reflective growing environment suitable from vegetative phase to intensive flowering phase.

This model belongs to the Master series and is distinguished by its higher load capacity, jumbo side doors, and professional finish for long-term use.

Maximum Light Output & Efficient Climate Management

The interior is finished with 97% certified reflective Mylar, which optimally reflects LED light back to the crop. This increases the efficiency of your grow light and ensures even light distribution across the entire canopy.

In combination with powerful LED grow lights from 480W to 720W, a stable, controlled indoor growing environment is created with maximum utilization of every watt.

The 200 cm height provides sufficient space for:

• Larger plant structures
• SCROG nets
• LST training techniques
• Powerful full spectrum LED panels
• Efficient air circulation above and below the canopy

Professional 600D Construction – No Compromises

The PROBOX MASTER 120 is made from extra thick 600D nylon fabric, significantly stronger than entry-level models with lighter fabric. This means:

• Better light-tightness
• Higher wear resistance
• Longer lifespan
• Less temperature loss
• More professional finish

The light-tight zippers and double stitching prevent light leakage and fully protect the light cycle.

Stable Patented Frame – 36 KG Load Capacity

The robust metal frame with Ø1.6 cm tubes offers a load capacity of up to 36 kg. This makes this grow tent suitable for:

• Heavier LED fixtures
• Carbon filters
• Inline exhaust fans
• Humidifiers or additional accessories

The higher load capacity makes this 120x120 grow tent ideal for complete professional ventilation systems with 150mm extraction.

Full Accessibility – Jumbo Side Doors

The Master series offers extra ease of use thanks to:

• 1 large front door (115 x 180 cm)
• 2 jumbo side doors (115 x 115 cm)
• Front inspection window (30 x 30 cm)

This ensures full access all around, ideal for maintenance, training, and control without disturbing the entire growing environment.

Optimized Ventilation Openings

The tent is designed for efficient air circulation and climate control:

• 3 air intakes (38 x 18 cm)
• 5 round extraction openings (Ø 16.5 cm)
• 3 cable passages (Ø 8 cm)

Perfectly compatible with 150mm ventilation systems and carbon filters for professional odor and climate control.
