This plant self watering kit from Vegtrug is an easy way of ensuring your plants are kept healthy and that they grow to their full potential. VegTrug self-watering system has a water reservoir in the bottom of planter part that supplies the soil of your plant with the necessary water through capillary action. As the plants absorb moisture from their roots and lose it through evaporation from their leaves, this creates a \'transpirational pull\' where the plant can have a continual source of water, allowing it to grow continuously and at peak performance. Features and Benefits: Water Level Indicator – This shows you instantly when your plants need water. Water Supply – This kit includes a shaft that makes adding water/ferterlizer easier. Water Conversation – Designed to minimize water losses through seepage or evaporation, the water reservoir is connected to a water level indicator that falls and rises accordingly to the amount of water. Nutrient retention – Over watering leads to the loss of precious soil nutrients. Since the water containers are enclosed, the nutrients do not get washed away and are preserved in the soil. Healthy root growth – It provides a failproof way to deep-water the container without being concerned about root rot. Well-cared-for root systems encourage larger, healthier plants.
