HOMEbox Ambient R300+ Grow Tent 300x150x220cm | Large High-Yield Indoor Grow Room

HOMEbox Ambient R300+ Grow Tent. Large Scale Controlled Environment System

The HOMEbox Ambient R300+ is a high-capacity indoor grow tent engineered for large-scale plant production under controlled environmental conditions. With an expansive footprint of 300 x 150 x 220 cm and a total grow area of 4.5 m², it is optimised for high-density cultivation and maximum yield output.

The enclosure is designed to support high-intensity lighting systems while maintaining stable temperature, humidity, and airflow dynamics. A multi-port ventilation system enables complex air management configurations, allowing growers to optimise air exchange rates, thermal dissipation, and CO₂ distribution across the canopy.

The structural frame utilises 22 mm powder-coated steel poles with reinforced connectors, providing a load capacity of up to 150 kg. This ensures stability when supporting multiple lighting fixtures, carbon filtration systems, and ducting infrastructure.

Total-blackout zippers create a fully light-proof seal without the need for additional flaps or Velcro closures, ensuring strict photoperiod control. A removable, water-resistant floor liner enhances hygiene and simplifies maintenance in high-output grow environments.

This system is designed for professional growers and advanced hobbyists requiring a scalable, high-performance indoor cultivation space.
