So take that pixel and make it one hundred times smaller. Yes, it is. It seems impossibly small. Even 10, PPM equals just one percent. Cannabis plants, like all leafy plants, absorb nutrients through their roots. Other nutrients, when taken in abundance, can actually damage the plant, causing issues with chlorophyll production or even effectively poisoning the plant.
Cannabis plants have different nutritional needs throughout their lifespan. For each stage of growth, a different concentration of nutrients is considered ideal. Using a TDS or EC meter to measure PPM is an accurate way to ensure your plants receive exactly the right amount of nutrients , and prevent them from soaking up too much of the wrong stuff. The 30 second guide covers only the most basic understanding of PPM and their relation to cannabis cultivation, while the two minute guide further explains the scientific concept of PPM.
This five minute guide aims to go through the process of purchasing and calibrating a TDS Total Dissolved Solids or EC Electrical Conductivity meter, measuring PPM in your water, and ensuring your plants are receiving the nutrients they need — no more, no less.
It also talks about how PPM and organic growing interact, and why your readings may not be accurate when you grow organically. TDS and EC meters are finely calibrated tools for measuring solubles in water. Both TDS and EC meters measure electrical conductivity in the water, and determine the soluble levels based on how conductive the solution is.
TDS and EC meters can be purchased from any hydroponics or growing store, or from many online retailers such as Amazon.
While almost any TDS or EC meter can be used, you may want to shop around to find one with the features, shape, and size you think will work best for you. The vast majority of TDS meters will display the total amount of dissolved solids in parts per million. For instance if you begin with deionized water 0 TDS , then expose it to minerals such as magnesium, sodium, and calcium, what will eventually happen is t he water's TDS or parts per million will increase.
What this means is even if you had these items in your water, a TDS tester will not capture these contaminants within the reading. In short a TDS meter is not sensitive enough to measure toxic levels of arsenic, lead, and even chromium-6, whilst present in the water sample.
A TDS tester reads items in parts per million, while the previously stated can be in your water sample at parts per billion or even parts per trillion. If you ever purchased a brand new water filter system from us you can rest assured it is working flawlessly and filtering out the contaminants advertised.

If you start with deionized water which has a TDS of zero , and expose it to minerals that contain sodium, calcium, and magnesium This is why there's no such thing as deionized water in nature.
There are two main reasons for this:. They must be measured by trained staff in analytical laboratories that use much more sophisticated scientific equipment. If you are concerned about water quality, put the money toward the purchase of an effective drinking water filter that removes harmful contaminants from your water.
