Green Box Tent 400 x 300 x 220 (With Wood Crate)

A Large-Format Grow Room in a Single Enclosure

The Green Box Tent 400 x 300 x 220 gives mid-to-large scale growers a full 4m x 3m x 2.2m footprint to run multiple plants and complete equipment configurations in one light-tight enclosure. The 600D silver Mylar interior reflects light back onto the canopy instead of letting it leak into the room, while a reinforced 25mm steel pole frame carries the combined weight of lighting, carbon filters and extraction without sagging. Double-stitched, light-proof seams and heavy-duty zips keep the environment sealed so you stay in control of light, heat and airflow. It ships secured in a wood crate for protected transport and storage between grows.

Key Benefits

• Large 400 x 300 x 220 cm footprint - room for multiple plants plus full lighting and ventilation kit
• 600D silver Mylar interior - maximises light distribution across the whole canopy
• Reinforced 25mm steel frame - stable under the load of lights, filters and fans
• Light-proof construction - double-stitched seams and heavy-duty zips prevent leaks and lockout issues
• Wood crate included - secure protection for transport and off-season storage

How to Use

• Assemble the steel frame on a flat, level surface before fitting the fabric cover
• Fit the cover, tension it fully, then check every zip and vent seals cleanly for light-tightness
• Hang lighting, ducting and carbon filters from the internal cross bars once the frame is stable
• Route extraction and intake through the pre-cut vent socks and seal around cables
• Fit the removable floor liner to catch spills and simplify cleaning between crops
