The GrowLab GL120 706835 grow tent has all the features you could ask for and more! This medium-large tent provides plenty of space for your plants to grow and thrive. Though nearly 7 feet tall, its 3 x 3 footprint is still small enough to save space in your grow area. Outfit the GrowLab with the ventilation fan, lighting system and growing system of your choice and you will have the brightest, slickest, most affordable grow room available. This grow tent utilizes intake and exhaust ports that allow adjusting to fit various sizes of ducting. The silver Mylar film used in the interior is highly reflective, waterproof, and extremely insulative (offering 97% thermal protection). This film is also non-toxic and will not release any harmful gasses that can damage sensitive plants.
