Placed in a location with 6-7 hours of direct sunlight, the Farm Tub growing system utilizes the best of hydroponic and soil growing. Your plants grow in soil with a wicking system that draws water from a reservoir below into the root zone. Watering from beneath allows for a more complex root system and prevents the soil compaction created by overhead watering. It also saves water by decreasing evaporation. The reservoir and wicks create a self-watering system through capillary action. Depending on plant varieties and growing conditions, you may not need to water more than every couple of weeks once plants are established.
