The Heavy Duty Premium Grow Tents are currently the best Grow Tents available in the UK. The Heavy Duty is the premium tent, for the grower who wants no compromises. It offers a durable, heavy-duty frame that incorporates metal corners, the thickest, strongest poles on the market and multiple choices of ducting and cable glands all with double seals. It is made of a new reflective material called UltraLux, offering up to 30% higher reflectivity and also has Tivax zips that provide a quality seal when closed. The HEAVY DUTY 2.4m has 25mm poles, 4 inline 300mm (12”) socks for use with air-cooled lighting, 4 100mm (4”) cable glands, 6 passive air fine (anti-mite) mesh vents at the base with light-proof covers for when they are not in use, 2 side doors plus a large rear door for easy access and 8 filter straps. It is ideal for 5 large plants and 16 mid-size plants. On this model, access from the front can either be by using the two inner curved doors or if full access is required, just zip the entire front off.
