Deep water culture is a hydroponic method which necessitates suspending a herbs root system in nutrient rich water. The root systems do not contact anything but nutrients, solution, and air. If the solution is properly oxygenated root systems can stay submerged for long period of time, if not some of the root has to remain above the water line to maintain exposure to circulated oxygen. Deep water culture’s capability to expose flowers to big volumes of minerals and air makes it capable of creating both big and quick harvests.
Common systems of deep water culture use big buckets or reservoirs to contain mineral solution. Flowers are then located in nets or containers which allow the root systems free exposure to the solution below. Floating flower holders could be used to automatically make sure the flowers remain at a constant level relative to the water.
Upkeep of static solution cultures is an crucial feature to consider. Sitting water could fluctuate in chemical concentrations over time and needs to be mixed regularly. To solve this problem many gardeners have installed recirculating deep water culture systems. These designs include of reservoir systems that premix and regulate mineral ratios. These systems combine solution in one container prior to watering making it easier to maintain continuous nutrient volumes.
Electric pumps can be added to the system making the process even easier for indoor growers to operate. Recent innovations in pump system designs allows for much greater concentrations of oxygenated water in cultivation containers. Many deep water culture growing systems are now being used with comprehensive recirculation systems. Compared to traditional static water cultures which were not regularly mixed present recirculated systems are contributing to substantially faster and better plant development.
Deep water culture can hopefully be further developed with new advancements to come. It is now one of the most effective hydroponic systems for grow rooms and with the utilization of better automation and designs it should become more convenient to install and run.
