Understanding PAR and PAR Meters
PAR, or photosynthetically active radiation, is a measure of light that plants use for photosynthesis. The amount of PAR a plant receives is important in determining its growth and yield. As such, it is important to have an accurate measurement of PAR in your indoor garden. This is where PAR meters come in. A PAR meter measures the amount of PAR in a given area, allowing you to optimize your grow lights and provide your plants with the light they need to thrive.
Misconceptions about PAR Meters
One common misconception about PAR meters is that they are unnecessary. Some growers argue that they can simply rely on the wattage of their grow lights to determine the amount of light their plants are receiving. However, this is not an accurate measure of PAR, as not all light is created equal. PAR meters are crucial in ensuring that your plants are receiving the right amount and quality of light.
Factors to Consider when Choosing a PAR Meter
When choosing a PAR meter, there are several factors to consider to ensure that you are getting the best one for your needs.
Accuracy
One of the most important factors to consider is accuracy. You want a PAR meter that is as accurate as possible to ensure that you are getting the most out of your grow lights. Look for a meter that has a high level of accuracy, ideally within 5%.
Range
You also want to consider the range of the PAR meter. Some meters have a limited range, which may not be suitable for larger grow rooms. Look for a meter that has a wide enough range to cover your entire grow space.
Price
PAR meters can vary greatly in price, with some costing several hundred dollars. Consider your budget when choosing a meter, but keep in mind that a higher price does not always mean better quality. Look for a meter that offers a good balance of accuracy, range, and price.
Ease of Use
Finally, consider the ease of use of the PAR meter. Look for a meter that is easy to read and understand, with clear instructions for use. Some meters may also offer additional features, such as data logging, which can be helpful in tracking the progress of your plants.
Top PAR Meters for LED Grow Lights
Now that we have a better understanding of PAR and PAR meters, let’s take a look at some of the top PAR meters for LED grow lights.
Apogee MQ-500
The Apogee MQ-500 is a popular choice among growers due to its high level of accuracy and wide range. It has an accuracy of +/- 3%, with a range of 400 to 700 nm. It is also easy to use, with a simple one-button operation and an easy-to-read display. However, it does come with a higher price tag, making it a better choice for serious growers.
