The 3-in-1 Lazy Gardener™ root management device delivers water vapor, heat & air directly into the root-zone. The Lazy Gardener creates ideal growing conditions by maintaining consistent moisture content, root zone temperature and oxygen levels. It delivers water vapor rather than liquid, which is the most efficient form of irrigation, eliminating overwatering & reducing water use up to 90%.It’s a “set it & forget it” product. Set the water up and walk away, maybe refill a once every week. All you need to supply is a power outlet and water reservoir. You will never have to worry about over- or under-watering your plants again. To find a Hydrofarm Authorized Retailer near you visit Hydrofarm.com.
