Our tents use the strongest available, diamond pattern, 1680D mylar that is 98% reflective so all of the light inside the tent reflects on your plants, making them grow bigger. Do not be fooled by cheaper 210D tents that will rip and tear over time (99% of the tents on amazon). One of the biggest issues with cheap tents is they use cheap zippers. We use the strongest zippers to ensure your tent can be used for many years and cover all zipper seams no light escapes through the seam. We use a full metal 22mm push button frame with smooth metal edge pieces to give us the highest hanging rating in the industry. You can easily hang HPS or LED grow lights from the frame along with any ventilation system. Our french door design allows for maximum workable space inside your tent. Our FREE included 12 inch height extension kit allows for higher yields by letting your plants grow taller. If you plan on growing more than once, you need this tent. If you buy a cheaper lower quality kit, you will regret it after your first cycle. Guaranteed.
