The SmartBee RootGuard is used to keep the opening in medium clear and to protect the root system of the plant. This allows the grower to maintain the same insertion point for the SmartBee Handheld Water Content Meter Probe and consistant readings. They come in a 5 pack.
All SmartBee products come with a one year warranty against defects in materials and workmanship, subject to certain terms and conditions. SmartBee will replace your defective gear at no cost to you. In addition, warranty coverage is also provided for the second year of ownership. During the second year, SmartBee will replace your defective gear after payment of a modest deductible.
