How do people grow plants hydroponically?
A popular technique is the nutrient film technique or NFT whereby a very shallow stream of water containing all the dissolved nutrients required for plant growth is recirculated past the bare roots of plants in a channel. This is a good option for production of smaller plants. With a Top Feed system, nutrient solution is periodically applied to the medium surface. This may be done manually once per day in large containers of some media, such as rock wool. Usually, it is automated with a pump, timer and drip irrigation tubing to deliver nutrient solution as frequently as 5 to 10 minutes every hour with lighter medias like hydroton. Deep Water Culture is a hydroponic method of plant production by means of suspending the plant roots in a solution of nutrient rich, oxygenated water. Traditional methods favor the use of plastic buckets and large containers with the plant contained in a net pot suspended from the center of the lid and the roots suspended in the nutrient solution.
