Plant roots hang suspended in the air and are periodically misted with the nutrient solution.Īs you may have noticed, each of these systems only defines the way in which the roots of a plant are supplied with life supporting water and nutrients. The nutrient solution is pumped through a channel in which the plant roots lie.
Plants are supported on a floating material while their roots hang below in the nutrient solution. Water efficiency at its finest! Deep water culture The water that isn’t consumed by the plant flows out the bottom of the tower and is then recirculated right back to the emitters. A wicking material helps draw the water to the roots growing throughout the tower. In our farms, emitters drip water down the vertical grow tower -less than 5 gallons of water daily to grow up to 5,000 plants. Drip SystemĮmitters drip the nutrient rich water solution onto a growing medium where the plant roots are located. This timing provides just the right amount of water for the seedlings to grow. A shallow trough, holding up to 12 trays of seedlings, is pumped full of water and then allowed to drain several times each day. The seedling stations in the our farms use this system.
Plants grow in a bed that periodically floods and drains with the nutrient rich water solution. Here’s the breakdown of the most common hydroponic systems, and a look into some of the techniques used at Freight Farms: Ebb and flow system Instead, a nutrient rich water solution is used to feed the plants, and there are many ways that this nutrient solution can be supplied to the plant roots. Let’s start with the basic benefits of hydroponic farming. Hydroponics is a method of growing plants without soil.
