How to grow hydroponic weed

There are numerous setups for growing hydroponically with varying benefits that were discussed previously here. And while there are several types of hydroponic setups that don’t use any type of growing medium at all, many of them still use some sort of substrate to support root growth.

Set Up Your Hydroponic Cannabis Growing System

The lower the ppm, the less nutrient-dense a solution is. As a general rule, aim for the following densities based on your plant’s age:

Nutrients for Hydroponic Cannabis

Raising a plant with hydroponics is different in many ways from growing in a soil garden. One thing to consider is the support the plant is receiving. Unlike a plant growing in soil, plants in hydro mediums might be vulnerable to tipping or breaking. Trellising your garden will help to prevent this from happening and will also allow you to train your plants to grow in specific directions.

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

Hydroponics is when you grow your cannabis plant in an inert medium like coco or a reservoir of water, and provide all the nutrients to the plant directly in the water.

Is Hydroponics Good for Growing Cannabis?

So there are five major parts to getting set up. You need….

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:

Differences Between Soil & Hydro

3: Aeration or oxygenation; usually in the from of an exhaust unit blowing air bubbles into the water;

  • 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.

(R)DWC: (Recirculating) Deep Water Culture

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.
