dwc, or deep water culture, is a type of hydroponic growing that doesn’t require any soil. The roots of the cannabis plant are instead suspended in a nutrient-rich water solution. This method is not for beginners, as it requires regular maintenance and a bit more knowledge about plants and nutrients. That being said, if you’re up for the challenge, dwc can be a great way to grow your own cannabis at home. In this guide, we’ll tell you everything you need to know about how to grow dwc cannabis, from setup to harvesting.

What is DWC?

DWC, or Deep Water Culture, is a hydroponic growing technique that uses a reservoir of nutrient-rich water to support the root system of your plants. The roots of your plants are submerged in the water, which is oxygenated with an air pump. This growing method is very efficient and can produce high yields.

Advantages of DWC

Deep Water Culture, otherwise known as DWC, is one of the simplest and most efficient ways of growing cannabis. The roots of the plants are constantly submerged in a highly oxygenated nutrient solution, which leads to explosive growth rates. With this method, you can achieve enormous yields in a relatively short space of time.

There are many advantages to growing cannabis with DWC. Firstly, it is a very simple system to set up and maintain. Secondly, it is very efficient in terms of water and nutrient usage. Thirdly, it allows for a high degree of control over the environment, which can lead to increased yields. Fourthly, DWC systems are relatively cheap to set up and run. Finally, they are very easy to scale up or down, depending on your needs.

Disadvantages of DWC

While DWC has many advantages, it also has a few disadvantages.

-It can be more difficult to control the environment in a DWC system, which can lead to problems with nutrient uptake and pH levels.

-If your system is not properly aerated, the roots of your plants can become waterlogged and oxygen-starved, leading to root rot.

-DWC systems can be expensive to set up, and they require regular maintenance to keep them running smoothly.

How to Set Up Your DWC System

Deep water culture, or DWC, is a simple but effective way of growing cannabis. Your plants will sit in a reservoir of nutrient-rich water, which will help them to grow quickly and efficiently. In this article, we’ll show you how to set up your own DWC system.

Materials You Will Need

-5 Gallon Buckets with Lids: You will need at least 4 of these, one for each plant you plan to grow. If you are growing in a larger space, you can use 7 or 10 gallon buckets. Make sure to get buckets with lids that fit snugly.
-Air Pump: This will provide oxygen to your roots. Get one that is strong enough to aerate all of your buckets at once.
-Air Stones: These go into your buckets and connect to the air pump. They diffuse the air coming from the pump and help aerate the water. You will need one stone for each bucket.
-Airline Tubing: This tubing connect your air stones to the air pump. It is important to get airline tubing that is made for aquariums, as regular Airline tubing will degrade quickly in water.
-Nutrient Solution: You will need a good quality nutrient solution designed for hydroponics or dwc systems. You can find these online or at your local grow shop.
-pH Test Kit: This is used to test the pH of your water and make sure it is in the correct range for your plants to absorb nutrients properly.

Step-by-Step Instructions

If you’re looking for step-by-step instructions on how to set up your own DWC system, you’ve come to the right place! Here, we’ll walk you through everything you need to know to get started, including a list of materials, a step-by-step guide, and even some tips on troubleshooting.

Here’s what you’ll need:

-A plastic storage container (we recommend a 5-gallon bucket)
-A lid for your container
-An air pump
-An air stone
-Silicone tubing
-Cannabis seeds or clones
-(Optional) A grow light
-(Optional) A humidity/temperature controller
-(Optional) A pH test kit
-(Optional) Nutrients
before setting up your DWC system, it’s important to remember that cannabis plants need three things to thrive: water, air, and light. With that in mind, let’s get started!

Maintaining Your DWC System

In order to maintain a properly functioning DWC system, it is important to regularly check and clean your equipment. It is also important to monitor the pH and nutrient levels of your water. By doing this, you can ensure that your plants are getting the nutrients they need and that your system is running smoothly.

Feeding Your Plants

Cannabis plants are heavy feeders and will need to be fertilized frequently. A general rule of thumb is to feed your plants once a week with half the strength that the manufacturer recommends. Depending on the size of your system, you may need to fertilize more or less often.

To properly fertilize your plants, it is important to first understand the nutrients that they need. Cannabis plants need three primary nutrients: nitrogen (N), phosphorus (P), and potassium (K). These are typically referred to as “macronutrients”. In addition to these three, cannabis plants also need “micronutrients”, which are minerals that are required in smaller quantities.

The ideal ratio of N-P-K for cannabis plants is 5-10-5, which means that the fertilizer should contain five parts nitrogen, ten parts phosphorus, and five parts potassium. However, it is important to note that different stages of plant growth require different ratios of nutrients. For example, during the vegetative stage, cannabis plants will benefit from a ratio of 3-9-6, while during the flowering stage a higher ratio of phosphorus is beneficial, such as 5-15-10.

When choosing a fertilizer for your cannabis plants, you will want to make sure that it contains all of the essential nutrients that they need. Many commercial fertilizers are “complete” fertilizers that contain all three primary nutrients (N-P-K), as well as essential micronutrients. However, some growers prefer to use “incomplete” or “partial” fertilizer blends that do not contain all three primary nutrients. This allows them to custom tailor the nutrient levels to their specific needs and Southwestern Ontario soil type .

No matter what type of fertilizer you choose, it is important to always follow the manufacturer’s directions in order to avoid over or underfeeding your plants. Applying too much fertilizer can “burn” your plants and damage theirRoot systems , while not applying enough will stunt their growth and prevent them from reaching their full potential.

Checking the pH Level

The pH level of your water and nutrients can have a big impact on how well your plants grow. The pH scale goes from 0 to 14, with 7 being neutral. Anything below 7 is considered acidic, and anything above 7 is alkaline.

Most cannabis plants prefer a slightly acidic environment, with a pH of around 6.5. That said, some strains can tolerate a slightly higher or lower pH. So, if you’re not sure what pH level is best for your plants, it’s always best to start on the lower end and then adjust as needed.

To check the pH level of your water and nutrients, you’ll need to use a digital pH meter. These can be found at most gardening stores or online. Once you have your meter, follow these steps:

1) Fill a test tube or small cup with your water and nutrients.
2) Use the digital pH meter to test the solution.
3) If the pH level is too high or too low, add an appropriate amount of acid or base until it reaches the desired level.
4) Retest the solution to ensure that it has reached the correct pH level.
5) Repeat steps 1-4 as needed until you achieve the desired results.

Checking the Oxygen Level

Different weed strains have different oxygen requirements. You will want to make sure that your DWC system is providing enough oxygen for your specific strain. The best way to check the oxygen level in your system is to use an oxygen meter.

You can find an oxygen meter at most aquarium supply stores or online. Once you have your meter, simply turn it on and insert the probe into your reservoir. The reading on the meter will tell you the dissolved oxygen content in parts per million (ppm).

For most cannabis strains, you will want to aim for a dissolved oxygen content of around 8-10 ppm. If the reading on your meter is below 8 ppm, you can add an air stone to your reservoir to help improve oxygenation.

Troubleshooting Your DWC System

If you’re having trouble with your DWC system, there are a few things you can check. First, make sure that your pump is working and that your timer is set correctly. Next, check your nutrient solution and make sure that the pH is correct. Finally, check your air pump and make sure that it is providing enough oxygen to your roots.

Common Problems and Their Solutions

There are a few common problems that you may encounter while using your DWC system. Luckily, they are all relatively easy to fix.

– Rattling or gurgling noises coming from your air pump. This is usually caused by an air bubble caught in the tubing. Simply remove the tubing from the air pump and allow the bubble to escape. reattach the tubing and turn on the pump.

– Yellowing of leaves and stunted growth. This is often caused by a lack of oxygen in the roots. Make sure that your air pump is properly aerating the water and that there are no clogs in the tubing or air stone. You may also need to add more plants to your system to help increase oxygen levels.

– Algae growth in your reservoir. Algae can be a problem in any hydroponic system, but it is especially prevalent in DWC systems. The best way to combat algae is to keep your reservoir covered and to use an algae preventative solution such as alum or copper sulfate.


To grow your own dwc cannabis, you will need to purchase a dwc kit, which contains everything you need to get started. You will also need to purchase a cannabis plant or two. Once you have your kit and plants, you will need to fill the reservoir with water and nutrients and then place your plants in the net pots. Once your plants are in the system, you will need to monitor the pH and nutrient levels, as well as the water level, and make adjustments as needed.
