Usage and installation

Assembling the G-MAX tent is quick and intuitive thanks to its 16 mm steel tubular frame. Simply assemble the frame, then slip on the outer fabric with the inner Mylar lining. Next, secure the waterproof ground pool using the hook-and-loop fasteners to ensure optimal protection against water leaks. Multiple sleeves with varying diameters allow you to discreetly position your extraction and intake systems, horticultural lighting, and cables without any loss of light. Be sure to tighten the cord locks properly to maintain a watertight seal.

To optimize your setup, pair this grow tent with a high-performance LED grow light, such as those in our SpectraWILD range, and a suitable ventilation system. This controlled distribution of light and air promotes uniform plant growth.

Maintenance and durability

To maintain the performance of your grow tent, regular maintenance is recommended. Clean the 600D nylon outer fabric with lukewarm water (max 40°C), avoiding harsh chemicals that could damage the material. Inside, a soft cloth can be used to dust without scratching the Mylar lining, which ensures excellent light reflectivity. Regularly inspect the reinforced seams and zippers to ensure there are no light leaks that could disrupt the optimal light cycle for your plants.

Thanks to its durable materials and construction designed for heavy use, this grow tent can support your projects for the long term, offering excellent dimensional stability and high resistance to wear. To maximize its lifespan, avoid overloading the suspension bars (maximum 20 kg) and do not move the tent when it is full of water, to prevent damaging the ground tray.
