Growing cannabis hydroponics systems

I n the previous post, we gave an overview of hydroponic gardening including its origins, the various systems and techniques, and medium options for a hydroponic grow. In this next article, we will focus how to use hydroponic systems specifically for growing cannabis.

What Is Hydroponic Cannabis?

Another common measurement used is ppm (parts per million) which is another way of looking at how nutrient-dense your solution is. There are two different scales for ppm used in the cannabis industry: the 500 and the 700 scale. The most efficient way to determine ppm is to take an EC reading, multiply it by either 500 or 700 depending on the scale you are using. An EC reading of 2.0 would equal either 1,000 ppm (500 scale) or 1,400 ppm (700 scale). Many readers used to measure EC or ppm will do this conversion for you.

If you’re thinking about growing cannabis plants, chances are you’ll think about pots filled with soil. However, in hydroponics, weed is grown in water instead of soil. This technique is also known as hydroculture or RDWC (Recirculating Deep Water Culture), but hydroponics is the most usual term. This method is not as complicated as many people think. Actually, growing gets easier with this technique, as plants will grow faster because they can absorb more nutrients. Hydroponics is suited for just about any plant, but it works especially well with vegetables and cannabis. This blog tells you just what hydroponics can do for you as a cannabis grower.

Using hydroponics for cannabis does come with a few minor drawbacks, though. Firstly, you’ll need to spend more on equipment before you can get your system up and running. Then again, working with the right system eventually pays off in terms of saving on water and electricity.

  • You can target your nutrition more accurately, because you don’t depend on what happens to be present in the soil. That allows you to set the perfect nutrient mix without losing valuable ingredients along the way;
  • Save yourself work: no need to remove weeds, while the system makes sure your plants are fed and watered. Just keep an eye on the water level in your reservoir. Two refill a week will usually do the job. As you can see, hydroponics is perfect for lazy relaxed growers;
  • Your plants will absorb the exact amounts of water and nutrients they need; no more and no less. The system simply recycles any excess water, making it a very efficient system too. Obviously, as a plant enthusiast, you care about the environment: life’s good when you can save the world by growing sustainable weed;
  • Pest control: hydroponics environments are cleaner than regular soil. That limits the options for pests and bugs – one thing less to worry about;
  • Better yields: plants grow better in hydroponics. For cannabis, that means better yields than for weed grown in soil, all other factors being equal;
  • Rapid growth: using a hydroponics setup could reduce the growth phase of your plants by three weeks. Roughly speaking, that could mean two extra harvests every year;
  • Not dependent on the weather: hot, dry summer? Freezing cold winter? It’s all the same for hydroponics, because all the plants get exactly what they need, no matter the weather. You don’t even have to keep track of the seasons – if you’re growing indoors, that is.

How Does Hydroponics Work For Cannabis Growers?

Basically, any plant can be grown using hydroponics. Cannabis thrives on it, but these days, you’ll find entire farms growing lettuce and leeks on water alone. Fun fact: the increasing popularity of growing cannabis at home has been one of the driving forces behind the development of new hydroponics systems used in regular agriculture!

Even though an aeroponic system is the riskiest and least suited hydroponic system for beginners in our list…

Your plants having access to nutrient-rich and oxygenated water 24/7 obviously means your plants are going to grow extremely quickly.

Here’s how it works:

And that’s exactly what hydroponic growing is:

What Else You Need…

There are different types of hydroponic growing systems all with their own pros and cons.

Getting bigger plants is also easier because of this growth acceleration.

Then there’s the danger of emitters clogging up and potentially ruining your grow…if you don’t keep your water and/or emitters free of nutrient build-up.

It’s also the highest-yielding system with the quickest harvest cycles.

But if you’re a beginner, you really need to understand the things that can go wrong in a system like this…and prepare carefully.
