When mixing in nutrients, take a few measurements to make sure your solution is safe for the plants. First, make sure you have the right EC (electrical conductivity) reading, and secondly, ensure your pH reading is correct.

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.

Next, you’ll need to balance the pH level. Between 5.5 and 6 is ideal for cannabis to absorb the nutrients. If levels are off significantly, the plants will fail to uptake the nutrients and will suffer deficiencies.

Nutrients for Hydroponic Cannabis

Various materials all provide slightly different benefits and drawbacks, so some thought should be put into choosing the right medium for your cannabis plants. In this article, we are going to be utilizing the drip line hydroponics technique.

Another thing to consider is pruning. With hydroponics, your plants can grow extremely fast. This means you need to be diligent about pruning. Removing all the bottom foliage and topping your plant before switching to its flowering cycle will allow your top colas (the large, topmost buds) to receive all the energy they need.

When growing hydroponically, you are responsible for providing all of the nutrients necessary for plants to survive. Nitrogen (N), Phosphorus (P), and Potassium (K) are the three essential nutrients for plant growth known as macronutrients. Additionally, there are secondary and micronutrients that will help the plant develop as well. These include Boron, Calcium, Copper, Iron, Magnesium, Sulfur, and Zinc.

Pros 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.

Differences Between Soil & Hydro

The pH level of your nutrient solution shouldn’t exceed 6.0 for a cannabis plant. You can go up and down by 0.2 but anything beyond that can harm your boo.

You’ll need pH and PPM meters. pH meters are used to check the acidic levels of the nutrient solution while a PPM meter determines how many Parts Per Million of a certain element is in your solution.

If you haven’t yet dreamt of having a field of cannabis, I doubt your love for weed, man. Imagine if you could grow your buds right at your home, maybe in your basement, or your garage. Isn’t it pretty cool?

I used to depend on the local headshops for potent boo until one of my friends came up with this idea of growing hydroponics marijuana in my basement.

Microelements or Trace Elements

One of the most amazing things about hydroponics is that you can directly apply the essential nutrients to the plant roots. And, the water that’s not absorbed by your plant gets recycled for later use.

For better understanding, you need to measure the solution strength twice a day and change the tank solution every two weeks.

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


Remember, a plant in its initial stage requires very fewer nutrients as compared to its flowering stage. The pH levels should lie somewhere between 5.5-6.0 while you can change the PPM level depending upon the growth stage of your plant, throughout the cycle.

The flavour that you get from your dab wax, plant sugars, and terpenes is all because of phosphorus. So, don’t hesitate to use a lot of it during the flowering phase.
