The QQ1530L is a patent-pending gazebo-style aluminum frame that expands effortlessly into place without separate poles or connectors. The frame confidently supports up to 150 kg, earning its reputation as one of the strongest pop-up tents on the market and comes with a reassuring one-year frame guarantee. Surrounding the frame is Green‑Qube’s signature 600D non-toxic PVA canvas, lined with highly reflective XREFLECT® mylar. MIL‑SPEC double zips, backed with rubber and StitchBLOK® foam seals, lock in light and moisture to industry-best standards. Ventilation is robust, including five large extraction ports, several cable inlets, and eight passive vents fitted with 700‑μm bug‑proof mesh and LightSavers® hoods—managing airflow without caveats. But if you’re a grower who needs more space for your plants, then consider the QQ300 3mx3mx2m or the QQ240L 2.4mx2.4mx2.2m.
