This Lotus II is made of stainless steel with a removable top and adjustable vents to allow for precise heat transfer. Keeping the lid off will produce the least amount of heat, having the lid on with the vents open delivers medium heat, closing the vents will create the most heat. Elevate Your Clouds™ The Kaloud Lotus Hookah Heat Management Device (HMD) regulates the transfer of heat from charcoal to Shisha, and also works to reduce the ash, ultra-fine particles, and volatile gasses that pass from charcoal into Shisha making your clouds smoother, cleaner, tastier, longer-lasting.
