How to Grow Cannabis in DWC
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!
Cons of Hydro
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
Is Hydroponics Good for Growing Cannabis?
So there are five major parts to getting set up. You need….
Benefits of Hydro Over Soil
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:
A hydroponic garden may exhibit a growth rate that is between 30% and 50% faster than that of a soil plant. The combination of nutrients, water, and oxygen in the roots are responsible for this faster rate of growth in hydroponic systems.
Some benefits of hydroponic growing are easier nutrient delivery, faster growth rate, water conservation, space saving, and year-round growing. Photo by: Gina Coleman/Weedmaps
How does hydroponic growing work?
Before you get started, you’ll need to gather the following supplies:
Is growing hydroponic easy?
While a soil-based garden may be easier to start, hydroponics facilitate easier nourishing of cannabis plants over time. Nutrient solutions allow for more precise dosing and direct feeding of the plants in a hydroponic grow system. The roots of the plant directly absorb the administered nutrients, often making growth an easier and more efficient process. Plus, once you’ve set up the hydro system reservoir, there’s not much maintenance to worry about.
