Top best answers to the question «What's the difference between hydroponics and deep water culture»
- In brief, hydroponics uses a water-based fertilizer and mineral solution to grow plants without dirt. These systems range in complexity. On one end are simple, deep-water culture systems in which plants are suspended above a container filled with water based nutrients.

Deep water culture is a different form of water culture in hydroponics. It’s called raft system as the plant float on top of water in a raft like system. In deep water system the water depth should about 8 to 10 inches deep.
Deep Water Culture (DWC) Deep water culture is sometimes referred to as deep flow technology, a pond system, or a raft system, but they all referred to the same type of system that consists of a large volume of nutrient solution with some type of raft that anchors plants and allows roots to grow into the large volume of solution and uptake nutrients and water.
If you’re new to growing plants hydroponically, words like “Deep Water Culture” can sound like they’re straight out of a science-fiction movie. Compared to soil gardening, hydroponics looks more complex – but it’s really not. There are many types of hydroponic systems, many of which have confusing sounding names (nutrient film technique, deep water culture, ebb and flow).
What differentiates the Kratky method from a DWC system is that the Kratky systems don’t use air pumps or any type of aeration. While on the other hand, a DWC system would require a constant oxygen supply through air pumps for the plant to survive. The misconceptions come from the fact that they literally look the same from the outside.

WHAT’S THE DIFFERENCE BETWEEN DEEP WATER CULTURE (DWC) AND KRATKY? To understand the difference between two methods, these illustrations explain it best. Basically the difference between the two is how oxygen is being supplied to the plant roots.
Deep water culture (DWC) is a hydroponic method of plant production by means of suspending the plant roots in a solution of nutrient-rich, oxygenated water. Also known as deep flow technique (DFT), floating raft technology (FRT), or raceway, this method uses a rectangular tank less than one foot deep filled with a nutrient-rich solution with plants floating in Styrofoam boards on top. 
hydroponic system called a water culture system. The word "Deep" in front is only used to describe some water culture systems when the water depth in the system is deeper than 8-10 inches, then it can be defined as an actual DWC system. However regardless of the water depth,
Let’s take a look at the main differences between hydroponics and aquaponics methods. Hydroponics systems are pretty germ-free, as they need no growing media to support the plants or root systems. Aquaponics, on the other hand, needs a growing medium around the roots to harbor beneficial bacteria – this can become a breeding point for germs and disease.
Deep Water culture or Direct Water Culture is a hydroponic growing method that sustains plants roots in a well-oxygenated solution full of nutrients and water 24/7. When we talk about “deep," we are trying to say that roots must be submerged deep in the water. So, the more water there is in the reservoir, the more stability in the nutrient solution and the less maintenance, and monitoring ...
