The GrowLab Horticultural Grow Room has all the features you could ask for - and more! Outfit the GrowLab with the ventilation fan, lighting system, and growing system of your choice for the perfect indoor growing solution. The GrowLab utilizes thermal film on the interior which is highly reflective, waterproof, and extremely insulative. This film is also non-toxic and won't release any harmful gasses that can damage sensitive plants. All of the zippers used in the tent are extremely durable. The sturdy powder-coated framework helps protect against rust, aid in installation, and enhance their appearance. Moveable roof cross-members make it much easier to adjust the positioning of lights, filters, and more. The included intake/exhaust ports adjust to fit various sizes of ducting. Drawstrings eliminate the need for duct hose clamps and make installation of ducting and fans quick and easy. The GrowLab 240 Horticultural Grow Room is a quad.
