Hydrolab’s LAB400 is a large indoor grow tent measuring 400 cm × 200 cm × 200 cm. It uses a 25 mm steel frame rated to 100 kg and a tri-layer 600D outer shell with a diamond-pattern mylar interior for high reflectivity. The layout includes two front doors with additional side and rear access, passive vent windows, removable spill trays, and straps for suspending fans or filters. Ventilation ports are oversized: 2 × 28 cm intakes, 6 × 34 cm exhausts, plus 4 × 28 cm air‑cooled reflector ports and cable socks. Hydrolab suggests an eight-light, 8 × 600 W configuration for this footprint. The LAB400 was added to Hydrolab’s range in 2016 and suits multi-light flowering rooms where stability and access are priorities.
