The Garden HighPro Probox 120 Grow Tent 120×120×200 cm is a professional indoor grow tent designed for growers who want to combine maximum space, stability, and light utilization in one efficient indoor growing setup. With a floor area of 1.2m² and a generous height of 200 cm, this grow tent offers optimal control over every growth phase – from vegetative to full bloom.

Thanks to its strong 420D canvas, robust metal frame, and 97% reflective premium Mylar inner layer, this 120×120 grow tent creates a stable, light-proof, and energy-efficient growing environment suitable for powerful LED systems and complete ventilation installations.

This size is ideal for serious hobby growers and advanced indoor growers who want to scale up without immediately moving to commercial sizes.

Maximum Light Reflection & Efficiency

The 97% highly reflective Mylar interior lining ensures optimal light distribution throughout the entire grow space. This prevents shadow zones, increases light intensity around the canopy, and supports uniform plant development.

In combination with modern LED grow lights (400W–600W), this tent provides efficient utilization of every watt of energy.

Benefits of 97% Mylar reflection:

• Improved light distribution
• Less energy loss
• Uniform canopy development
• Optimal photosynthesis support

Robust 420D Construction – Light-proof & Durable

The 420D heavy-duty canvas outer layer is tear-resistant, abrasion-resistant, and completely light-proof. This guarantees stable day and night cycles and prevents light leakage during the flowering phase.

The reinforced metal frame (Ø1.6 cm tubes) supports up to 28 kg and effortlessly holds:

• Heavy LED grow lights
• 6-inch inline fans
• 150 mm carbon filters
• Climate controllers
• Oscillating clip fans

This load capacity makes the Probox 120 suitable for professional indoor setups without loss of stability.
