Some gravel media can even leach mineral substances into the solution, resulting in chemical imbalances. The tray is flooded by manually raising the bucket and drained by lowering it. By adding a pump and timer, the basic unit evolves into an automatic hydroponic system. The solution trickles through the medium back to the reservoir below the growing bucket. Media such as expanded clay pellets or perlite distribute the nutrient in a wide circle around the plant roots.
Drip systems are flexible.
You can adjust the nutrient flow for individual plants within the same system by changing the number of emitters or their size, allowing plants with different nutrient and water requirements to be grown together. Although drip systems are easy to set up, construct, and operate, maintenance can be a problem, especially if you use organics in your nutrient solution. The emitters clog on occasion and then need thorough cleaning. Inc. All rights reserved.
