What is deep water culture (DWC) hydroponics, and how does it work?

Deep water culture (DWC) hydroponics is considered to be one of the most simple hydroponic methods for experienced and new indoor growers.

Plants are immersed or simply connected with a nutrient solution put in a water tank. The plants are in a soil-less net cup, either floating on the surface or within a container.

Air is pumped into the reservoir using an air conditioner and an air delivery device like an air stone. This keeps the water provided with the quantity of oxygen necessary for the roots of this plant. The increased pot or internet cup is full of a growing media like gravel, clay pellets, lava rock, etc., it is suspended in the nutrient solution.

The trick to rapid growth is to be sure that the roots are touching the water if the crops are in their youthful stage. Since the plant grows and you see signs of sources growing down to the water, you can now drop the water level.

Aeration of a Deepwater culture hydroponics system is among the main things in the system. Allow me to explain; traditionally, you’d use an air stone to offer air to the reservoir or pot.

It’s more important to offer an even flow of air throughout the whole reservoir or marijuana than it is to provide a larger quantity of air in some of the pool or marijuana. If you can look back on your reservoir or pot’s surface and see a void of air bubbling towards the top, you have a system hole.

The roots below aren’t receiving the right quantity of air. This void can be removed by using Air Injection Technology manufactured by It permits an even air distribution in the reservoir or marijuana. There’s nowhere the roots can hide; they’re exposed to oxygen and air anywhere in the reservoir.

By way of instance, if you’re growing in a 5-gallon bucket and are using a 3-inch air rock, you have a void of about 7 inches. Where you do not have air bubbling up, this is a void area; You have roots exposed to the void area and aren’t getting the amount of oxygen they need.

Additionally, when using an air delivery system that doesn’t evenly distribute air to the whole reservoir or pot, it has a tendency to push the roots into the void place.

Here are Some of the Pros & Cons of the DWC hydroponics system:

Benefits of DWC hydroponic systems

  • Low maintenance
  • Fast-growing time
  • Minimal moving parts

Cons of DWC hydroponic systems

  • pH and water level can fluctuate
  • Simple to overfeed or underfeed
  • Difficult to maintain a consistent temperature in the reservoir

How can DWC hydroponics systems operate?

In a recirculating DWC system, plant roots are suspended right in a hydroponic nutrient solution. A hydroponic reservoir places this remedy, and because the roots remain in this reservoir during their life, there isn’t any requirement for a water pump.

An air pump and air stone supply constant oxygen into the root canal, preventing plants from drowning.

DWC hydroponics is terrific for new growers since there are just a few components. Unlike hydroponic drip systems or aeroponic systems, there aren’t any nozzles that can get clogged. This drastically cuts down on the required care for your DWC system. As soon as you get your system setup, it is smooth sailing! But, hydroponics, generally speaking, isn’t necessarily a cakewalk.

The Hardest Aspects of Growing With DWC Hydro systems

The majority of the issues with recirculating DWC techniques come down to human error. That is why we encourage novice growers to begin with the soil. But if you use a thermometer/hygrometer and a pH pen, it’s not difficult to prevent lots of the problems that arise with this manner of growing!

Dosing nutrients correctly is also very significant since there isn’t any buffer (like with dirt ), and thus mistakes made out of feeding are magnified. For large business DWC systems, it usually makes more sense to use nutrient and pH doses simply. This helps maintain optimal conditions in your water culture system and protect against human error. On that note, let’s quickly discuss hydro nutrients.

Which Plants to Grow DWC

The most appropriate plants to develop with deep culture systems do not need to blossom, including many lettuces and many different herbs. These crops grow super fast and healthy. Besides that, you may also grow tomatoes, peppers, as well as bigger fruits like squash even though they take somewhat more effort.

What Sorts of DWC Should You Start First?

If you are just beginning, it’s strongly recommended that you try with the conventional DWC or the Kratky method. These are extremely simple to set up, inexpensive while still producing excellent yields that you would enjoy. Start small, you begin. It’s possible to grow large later once you’ve got enough experience.

Bottom line

Deep water culture system is a method of growing plants in aerated water. Many growers believe this system to be the purest type of hydroponics.

If you’re a beginner in the subject of growing plants with the hydroponics method, this is a cheap (compared to other alternatives ) and easy DIY installation that beginners and more established growers both love.

With enough aeration from the water and the ideal temperature, the plant roots will flourish, and the expansion rate and yields that this technique can achieve are phenomenal.
