How to grow hydroponic cannabis

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!

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

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:

Hydroponics is on the rise; mostly because it gives growers greater control over how their plants develop. Instead of growing your weed plants in soil, you grow them directly in water containing all necessary nutrients. That comes with some distinct advantages, making this technique an interesting option for advanced and amateur growers alike.

Liquid Lunch: Nutrients Straight From The Water

The one thing all hydroponics systems have in common is the lack of soil needed to grow your cannabis plants. Hydroponics gets your cannabis plants everything they need, except light: nutrients, oxygen, and water. This can be done in several ways. Below, you’ll find a summary of the most common hydroponics systems.

RDWC is the easiest system to manage, making it a great option for beginners. You put your germinated plants into individual containers, which you then place into a water container. All you add is some hydro pellets to give the roots some added grip. An air pump ensures a constant air supply into the water. Nutrients are added to the water, which the plants can then absorb through their roots. That means roots are constantly exposed to water throughout the growth cycle. The R in RDWC stands for Recirculating, because the water is constantly pumped around the system in a closed loop.
