Hydro is a no-brainer for me. Whenever I go back to a hand-watered grow like coco coir, I am always surprised by how much extra time it takes to water plants and remove the runoff. The most intimidating part of hydro is just getting started – after that it’s actually really easy to take care of your plants. In my opinion, hydro is far easier and less time consuming than growing in soil or coco coir once you’re set up. If you are interested in hydro, go for it! If you follow this tutorial you will succeed!

Today I’ll teach you how to set up your hydroponic reservoir for growing cannabis, and I’ll show you what you need to do each day for optimum growth

Differences Between Soil & Hydro

Have you seen cannabis plants growing with their roots just floating in a reservoir of water? This type of hydroponics is known as Deep Water Culture (DWC), and has been around for over a 100 years! As more growers gain experience with this medium, DWC has become increasingly popular for growing cannabis. Hydroponic setups are really neat and offer some big benefits over growing in soil!

Benefits of Hydro Over Soil

Pros of Hydro

Growing in coco coir can be considered a type of hydroponics since it naturally contains no nutrients and you must provide all the nutrients in the water. However, when you say “hydroponics” most people think of this:

How to Grow Cannabis in DWC

Here are the recommended nutrient densities for a cannabis plant:

Since every element is given in different amounts to the plants, it’s crucial to keep a quantity check on the solution.

Growing cannabis through hydroponics is tricky, but, once you get a knack of it, it’s worth all the efforts.

As discussed, hydroponics is a technique of growing plants indoors without using soil. Now, it can be any plant, marijuana, cannabis, or even garlic. But, we are explicitly talking about cannabis/marijuana in this article.

Microelements or Trace Elements

Nitrogen is one of the most essential elements of all. It helps building enzymes, proteins, and chlorophyll in the cannabis plants. Chlorophyll is further responsible for photosynthesis that helps the plant to grow.

Step 6: Insert the saplings

Before starting with anything else, let’s brush up our basics. Hydroponics is a technique used to grow plants without soil while suspending the roots in water, gravel, sand, coco peat, Rockwool etc.


A reservoir or a water tank is where you add the nutrient solution and, its size depends on the size of your grow room. The air stone and water pump are placed inside the reservoir. A line from the air pump and the drainage line goes into the reservoir. The line from the water pump to the drip line and the power cord for the water pump will go out from the reservoir.
