pH value is one of the most important things for any hydroponics setup. Too high or too low of a pH value can really have a devastating effect on plants. It's not uncommon for growers to see the real effect of extreme pH levels in withering plant stems, burned or yellowed leaf tips, or other signs that plants are not doing well.
So how do you provide for this very specific chemical puzzle? How do you keep the right pH in a hydroponic environment?
Here are some ways that growers around the world safeguard their plants from the hazards of improper pH levels.
Regular Measurement
One of the biggest fundamental ways to control pH is simply to measure it by hand at regular intervals. Growers can then add or subtract materials to fine-tune the pH to where plants are comfortable.
Chemical Buffers
Some products referred to as calcium buffers or other types of additives help keep pH value stabilized within a plant environment. In some cases, growers can add these regularly to keep a pH level range tighter, and prevent some of the problems that out-of-control pH can cause.
Ion Exchange Principles
Other tools work on the principle of ion exchange, a molecular way to keep ph right. Materials called ion exchange resins can be added to the reservoir environment and in theory, this can help control the pH to achieve constant levels. There is some cost up front, but these types of materials can last for a long time and help keep the pH workable, so that more plants survive and thrive in each crop cycle.
Available Hydroponics Tools
Some of the newest, most advanced hydroponic equipment systems have built-in monitoring tools that will also help growers to watch out for high or low pH value. These laborsaving setups can help make hydroponic easier for a grower to keep track of ph. Easy tools like pH up and pH down can be added by hand, or in some cases, a system will even add them automatically. It's all part of better observation and environmental control for indoor or hydroponic greenhouse plants.
