Dwc weed grow

If you’re new to growing cannabis and don’t want to build your own system, there are plenty of DWC ready-made systems kits online with everything you need. If you want to go build your own, a DWC system has the following components:

We recommend using organic nutrients for the best results. If you’re a beginner, consider investing in complete grow systems that include solutions for every stage of growth. Some of the most popular ready-made nutrient options include General Hydroponics’ Flora Grow Series or FoxFarm’s Trio formula.

Easy DWC Grow Start to Finish Set Up

For the best indoor grow system, refer to the greatest DWC grow start to finish guide for growers of all skill levels. Deep water culture (DWC) systems are popular types of hydroponic systems that use only water, nutrients, and a growing medium to produce stronger roots and better buds.

This method is particularly effective due to the constant pumping of fresh nutrient solution. In addition, the lateral flow of this system can increase your roots’ health, growth rate, and yield.

What Is Recirculating Deep Water Culture?

In the beginning, you won’t need to replace the nutrient solution as frequently compared to when the plant has matured. How often you replace the nutrient solution depends. It could be every one to two weeks or longer.

This page about different cannabis grow lights goes over the options in more detail, but we’ll give you the basics here.

You should always clean and vacuum out your growing area before you start a grow (for bugs, dust, mold, etc.). You may also need to have your reservoir raised off the ground depending on how you plan to drain it; we’ll cover that in a bit. I use a battery powered pump (which I recommend), so in my case raising the reservoir isn’t necessary.

Grow Lights:

These powerful lights are pretty much seen as the golden standard for indoor growing lights. They will definitely give your plants what they need to grow huge, but they also make a lot of heat and can dramatically raise your energy bill depending on where you live.

But for someone that has only grown in soil before there are some undeniable added new complexities to consider. You will need a, perhaps slightly noisy, air pump to feed the DWC air stone and you may need to discover the joy of owning and calibrating pH and EC meters for the first time.

Many serious growers change the nutrient bath at fixed schedules, often weekly. You may be able to leave your nutrient bath 1-2 weeks between changes in veg. But in bloom, with hungry plants you should aim for complete weekly nutrient bath changes at a minimum. Pro growers may change baths even more frequently than that. They will check their baths once or twice a day in late bloom, topping up with nutrients.

A DWC cannabis grow comes in many different styles and adaptations. However the common theme is that the roots are immersed in a bath of nutrients at an optimum pH, often around pH 5.8. Normally cannabis roots left in water/nutrients would eventually rot. But the presence of bubbling air (e.g. from a DWC air stone, connected to an external air pump) provides the roots the oxygen they need to grow with great vigour.

The benefits of growing cannabis with DWC

Growing in a DWC cannabis system isn’t for everyone. But for those that do it well, dry yields of several hundred grams per plant are quite routine. Deep water culture cannabis growing pushes hydroponics (soil-free) cultivation to it’s limits. As such, it’s the ultimate thrill and ultimate challenge for many indoor growers. For those that truly enjoy their cannabis cultivation there are few more satisfying feelings than seeing a crop grow from seed to harvest. When you harvest your first DWC monster the joy and satisfaction will be remembered forever.

The container is often simply a deep bucket (hence the name, DWC) which is often black in colour. The absence of light keeps dreaded slime and algae to a minimum. One plant can comfortably fill the typical 15-20 litre DWC bucket full of cannabis roots by the end of the grow. A healthy root ball is a huge white mass of roots.

Growing cannabis in DWC system

Deep Water Culture (DWC) is the technique of growing cannabis plants with their roots growing in a bubbling (aerated) nutrient bath. Growing cannabis in a DWC system is claimed by many to be the fastest way to grow heavy yielding cannabis plants. However, the technical complexity of correctly maintaining the pH and concentration of the nutrients does place certain requirements on the grower. DWC cannabis growing offers great rewards, but it is far from the easiest grow technique to master.

The main attractions of growing DWC cannabis are the fast growth rates and huge yields that are potentially on offer when DWC is done well. For those that delight in the joy of growing their own cannabis, there is an undeniable satisfaction that comes from seeing a successful DWC grow really push the cannabis plant right to it’s limits.
