Our NFT Hydroponics System Set-up
Our pump has a capacity of 30 watts. Due to the height of our system being above one meter, we lose a few watts of power, placing our output anywhere from 20 to 25 watts.
For our system, 5 tubes feed off of one pump. First, a singular PVC pipe runs vertically from the bucket containing our pump. The one water source is then split into three using a cross connector. One pipe goes directly from the cross connector up to the middle tube. From the cross connector to the left, a T connector was used to again split the stream into two. Moving up from the T connector, the water feeds a second pipe. To the left of the T connector, an elbow connector redirects the flow of water up to a third tube. From the original cross connector to the right, the system mirrors the left, feeding two additional tubes.
Each pipe will pass through a tap before pouring into the tubes holding the plants. The tap controls the amount of water dispensed into the tubes, if the system is not completely level, you can adjust the tap to balance the water distribution in each tube. At the end of the tubes, we used small pieces cut from a rubber hose to regulate the water level as it drains. The ideal water level is less than half of the basket holding your plant, thus exposing just the roots to the nutrient-rich water. Another wider 3-inch PVC pipe collects the water as it flows out from the five tubes. This pipe angles at a slight decline back into the tank to complete our circular loop nourishing the roots of the plants.
