Stay Cool with LED Lights: How LED Lights Keep Temperatures Low in Your Facility
Temperature is one of the most important aspects of any grow facility, and LED technology makes managing temperatures stress-free. Keeping your indoor grow at an optimal temperature will produce positive results for any crop—LEDs ensure cultivators have complete control over indoor conditions.
Why is temperature important to monitor in your grow?
Control and closely monitoring atmospheric conditions is imperative, as temperature plays an enormous role in plant growth and nutrient uptake. Temperature affects a plant’s ability to photosynthesize and germinate. Photosynthesis refers to the process by which plants convert light into nutrients. Germination, on the other hand, is when young plants sprout from a seed. Temperature has also been shown to play a role in flowering and producing fruit. These are all necessary points in the plant’s growth—any grower will attest to the importance to maintaining the perfect temperature for the healthiest results. In addition, keeping a cooler temperature will prevent unnecessary evaporation, saving the cultivator water over time.
There are a few factors seasoned cultivators take into consideration when measuring temperature. With LED lights, it is possible to actually track the amount of PAR (Photosynthetically Active Radiation) received by each plant. With higher levels of PAR, plants respond by increasing their metabolism, nutrient uptake, and overall growth. Warmer and consistent temperatures paired with high rates of PAR facilitate faster, robust growth found across healthy crops.
In addition, many LED growers refer to the Vapor Pressure Deficit (VPD). This measurement illustrates how temperature and humidity interact within a facility.
To emphasize, an indoor cultivation facility’s temperature can impact:
- Flowering & producing fruit
- Water usage
Simplifying your system
Over the years, indoor growers have become accustomed to complicated systems to ensure optimal temperatures. This often includes an array of fans, complex air conditioning units, and lots of hands-on labor to ensure plant health.
Conventional lighting technology can produce red-hot temperatures at the bulb’s source—some have even been recorded at 1,400 degrees Fahrenheit. This heat is transferred to the air, creating a too-warm environment for crops. Of course, this also prevents the cultivator from placing plants too close to the bulb, or having too many lights in one space. Using conventional lighting options improperly can result in literally burning your plants.
With LED lights, though, a grower will spend less time worrying about burnt plants.
Low temperatures and high quality with LED
While LEDs do produce some heat—contrary to some marketing claims—they operate at much lower temperature than other lighting options. This cooler temperature allows cultivators to fit more lights and plants into a growing facility without drastically altering the indoor temperature.
An LED bulb won’t burn because it lacks heat created by infrared radiation (IR). Incandescent bulbs, on the other hand, produce infrared radiation as an aspect of their design, resulting in a very hot bulb and fixture. Therefore, LED fixtures use energy efficiently: more power is converted into useful light and PAR than excess heat.
Installing energy efficient lighting will reduce costs in your facility. Without excessive heat produced by lighting, growers won’t need as much air conditioning, fans and other temperature control systems. Furthermore, keeping temperatures low in a facility reduces water usage—another reason LEDs are a more environmentally conscious choice.
In summary, there are several benefits for installing cool-running LED lights:
- More energy is devoted to emitting usable light
- Growers are given more control over the indoor temperature
- Lower temperatures reduce need for cooling systems and excessive water use
