Cultibox Open 300 XL 290×290×200 cm – Grow Tent

Cultibox Open 300 XL is a large grow tent measuring 290 × 290 × 200 cm, designed for convenient plant care and easy installation of all necessary equipment. The Open series stands out thanks to its wide-opening design, which provides excellent access to the inside of the tent from several sides.

Thanks to the additional rear doors, working with plants placed deeper inside the tent is much more comfortable. This makes watering, plant care, pruning, crop inspection, and installation of ventilation, filters, lighting, and irrigation systems much easier. It is a very practical solution, especially with such a large working area.

The inside of the tent is finished with diamond reflective material, which reflects light very effectively and helps distribute it evenly throughout the growing area. The thick, lightproof fabric reduces light leakage, while the strong construction allows you to safely install essential equipment such as a carbon filter, fan, ventilation ducts, and grow lights.

Cultibox Open 300 XL features 4 adjustable ventilation ports with a diameter of 13 inches / 325 mm, 4 cable outlets, an intake opening, and passive ventilation mesh windows. The ventilation sleeves are equipped with drawstrings, making it easy to adjust them to different duct and fan diameters.

The tent also includes a removable waterproof floor tray, which protects the interior from moisture and dirt. Its large size, functional port layout, and easy access to the inside make this model a great choice for advanced indoor grow setups with professional lighting, ventilation, filtration, and automatic irrigation systems.
