Best DWC System (Deep Water Culture): Reviews (2023 Update)

If you are looking to start out growing your own cannabis, or if you already have a small plant growing and are looking to expand your operation, you would do well in investing in a Deep Water Culture (DWC) system. This allows you to supply your plants with water and nutrients at a controlled rate or frequency, depending on your specific needs. DWC systems are known to grow weed much faster in the vegetative stage than they do in soil. We have listed the most important factors to look for when buying a DWC system below.

Bucket or reservoir material quality

Because you’ll be storing your water and nutrients in a bucket or reservoir, you want to ensure the material used are of high quality. Your plants depend on the nutrients you put in the water, so you want a bucket that protects these nutrients from light. You want to make sure your bucket doesn’t get contaminated either. Some growers prefer sterilizing their reservoir while others prefer to introduce beneficial bacteria into the bucket.

Mesh/net cups or baskets

Your plants will be placed in a mesh or net cup filled with peat moss or rockwool soil. You want a manufacturer that uses high quality material for the mesh bucket, as your weed will be planted in it.

Air pump

This is one of the most important components of a DWC system. The air pump ensures your plant roots get enough oxygen so that they won’t drown. You want a durable air pump to provide your cannabis roots with constant oxygen. Because you need to run the air pump 24 hours a day, some people shell out more for quieter versions.

3 Important factors when growing with a DWC System

When using a DWC system, there are 3 things that you should constantly check: the pH levels of your water, nutrients in the water, and the temperature of the water.

Ph level

While it may seem tedious, you should check the pH levels of your water often; at least once a week. For a DWC system, you’ll want to aim for 5.5-6.5 pH. Cannabis thrives in slightly more acidic levels.

Nutrients

Nutrients will be feeding your cannabis, ensuring its growth. It’s recommended that you change your reservoir water and put in new nutrient rich water every ever one to two weeks, depending on your strain. Some strains are more high maintenance and require a change every week.

Temperature

Optimally, your water should be around 60-70°F. If your grow room temperature is within a good range, your water temperature should also be okay. Still, it doesn’t hurt to check the water temperature every now and then.
Because there exists a plethora of options available on the market, complete with DIY solutions, here are some ideas for popular alternatives to consider to help you narrow down your search before committing to a purchase.

SuperPonics 16 Hydroponic Grow System

This fully automated 16-plant hydroponic grow system combines top feed watering and bottom feed oxygenation. This combination allows your plants to thrive. What we love about this grow system is that it’s simple to set up. The system already comes fully assembled; all you need to do is add in water, nutrients, and plug it in.
This kit includes 16 Net Cups at 3’ per cup. To ensure your plants get enough oxygen, this kit has an Eco Air 4 air pump and high output air stones. The Eco Air pump is used in many hydroponic grow systems because it’s durable, quiet, and convenient to use. The 185 GPH (gallon per hour) pump ensures your plants won’t go thirsty by pumping up water to your plants. The analog single timer waters your plants regularly for you, so you don’t have to worry about doing it yourself.
One thing to keep in mind is that this system doesn’t come with nutrients (some other high-rated systems do) so you will need to purchase those yourself.

Conclusion

We hope this information will help you pick the right DWC system for your growing needs. As stated earlier, the air pump is extremely important for delivering oxygen to your weeds’ roots. An air stone will allow the oxygen to cover more surface area. When you begin growing, make sure you regularly check the water temperature and pH levels. Happy growing!
