Deep Water Culture System, What is Deep Water Culture (DWC)? Deep water cultivation or direct water culture is a type of hydroponic farming method in which the roots of the plants are continually suspended in nutrient-rich, high-oxidized water.06-Apr-2021,
If you drain, clean and remix the nutrients every 7 to 10 days, it's okay to top off with fresh water daily. As plants consume nutrients and water, the nutrient strength in the hydroponic reservoir will change. GENERALLY, nutrient strength should run between 800 to 1500 parts per million (ppm).
A DWC system dangles net pots holding plants over a deep reservoir of oxygen-rich nutrient solution. The plant's roots are submerged in the solution, providing it with perpetual access to nutrition, water, and oxygen. Deep water culture is considered by some to be the purest form of hydroponics.06-Sept-2019
The aquaponic and hydroponic roots do not require light but can be exposed to some degree of light. Although light may not harm the roots, overexposure can lead to algae growth on the roots which can give it a green hue from the chlorophyll.
For your DWC, the ideal pH is around 5.8. Make sure not to stray out of a pH range between 5.5 and 6.5. One advantage of DWC is that it can require less nutrients than other growing methods. However, you should be regularly monitoring the pH of your feeding solution.25-Nov-2021
The Kratky method is a form of passive hydroponics. There's no need to change out the water, nor is there a concern about rejuvenating oxygen for the plants. As the plant grows, the water level drops, creating air space for the roots. When the plant is ready for harvest, the nutrient-filled water is nearly used up.30-Dec-2021
We recommend changing out your reservoir water completely every 7 – 10 days. Even though you can top off evaporated water by measuring and not exceeding overall PPMs, you can't measure the ratio of different nutrients left in the water after plants have used part of them up.
When talking about Hydroponics, we cannot miss talking about the Deep Water Culture technique. As true Hydroponics in its purest form, Deep Water Culture is definitely among the easiest yet most effective type of Hydroponic systems.18-Feb-2022
