Spectrum King Phoenix 840W LED Grow Light VS Grow Light Science PROGROW 850 850W LED Grow Light

 One of the indispensable and irreplaceable elements of growing plants is considered a special lamp. Growers who specialize in hydroponics are especially careful when choosing lighting equipment because plant is a light-loving crop. Its growth, development and quality largely depend on lighting. Choosing the right grow lights and deciding how many to install must be based on the advice of a more experienced grower. So let’s examine the possible options together in this article.

What are the best grow lights for indoor plants?

Fluorescent store lights have been used as grow lights for many years. But recently, LED grow lights have replaced them as ideal seed grow lights.

Although LED lights are more expensive than traditional lights, they are practical and energy efficient. LED lights also generally last longer than other traditional lights.

What color light is suitable for seed germination?

In general, red light has the best effect on seed germination. You will find that plants utilize the full spectrum during photosynthesis.

But red and blue lighting on plants has the best growth. You need to be careful not to overexpose the seeds to red and blue light, as the plant may grow taller than expected.

PROGROW 850 provides high PPFD levels and can be used with CO2 supplements. Top light output (PPF), spectral distribution and efficacy will deliver amazing results with little impact on your wallet. PROGROW 850 will deliver PPFD levels of over 1,400 umols/m2/s, either individually or in arrays of multiple cells. We recommend that all growers conduct research and trials within their growing space to design the best combination of inputs.

Why choose LED lighting for growing plants?

1. Greater efficiency
There are two trends in the market for lighting that affect the vast majority of growers around the world. The first, which has been going on since LEDs were introduced to the market and which producers are most familiar with, revolves around the benefits and challenges of switching from legacy lighting solutions such as high pressure sodium (HPS) luminaires. for LEDs.

The initial adoption of LED was primarily driven by its energy efficiency and cost savings. For example, commercial wide-spectrum LED lights achieve 2,6 micromoles of photosynthetic photon flux (PPF) per joule of electricity over their lifetime, compared to HPS lights, which average 1,9 micromoles per joule. LEDs also dramatically reduce maintenance and replacement costs that legacy systems most often incur. These efficiencies have spurred several institutions and programs to offer generous subsidies and discounts to producers upgrading to LED systems. These savings, along with reductions in HVAC costs, have made LEDs a worthwhile long-term investment for growers around the world.

The second, a relatively new discussion for many growers, applies to those who have already adopted LEDs but are looking for research and insights to identify the correct light spectrum and composition that addresses your unique growing conditions, including geography, facility type, environmental conditions and cultivars.

Both conversations almost always involve an efficiency component. But where the supremacy of LEDs over legacy lighting has been well established, some growers already using LEDs may be tempted to deploy lighting strategies that favor low light intensity and wavelengths such as far red, red or pink, in an effort to reduce the energy consumption.

However, in the quest for greater efficiency, they may be sacrificing greater revenue. Many crops — favor high-intensity, broad-spectrum strategies that improve overall yields and plant quality, on crucial attributes such as improved morphology, terpene profiles and cannabinoid content.

Efficiency doesn’t mean optimization, and cost savings mean little if you’re not also maximizing revenue potential. Any LED-based operation seeking efficiency gains must balance this with an analysis of the lighting strategy that will get the most out of their crops.

2. Better quality and yield
While projected savings have driven the early adoption of LEDs, their greater effectiveness and ROI (return on investment) have emerged as key factors in their sustained popularity. It is now understood that increasing light intensity and spectral quality correlates with substantial increases in a crop’s yield, morphology and health. In one study, researchers found that a 1% increase in photosynthetically active radiation (PAR) corresponded to a 1% increase in harvested product up to light levels of 1.500 µmol/m2/s. By optimizing installations with LEDs and vertical racks, growers are realizing that they can realize profits that far outweigh the already significant savings.

3. Improved control
LEDs provide enhanced control over almost every parameter of a operation. Most critical is, of course, the ability to manipulate light intensity and spectral composition in order to maximize yields and production.

Understanding the impact of LEDs on environmental controls, however, is just as important, especially for growers who have recently switched from legacy lighting or are considering doing so.

There are main control parameters that LEDs enhance:

● Management of vapor pressure deficit (VPD) becomes possible
HPS lights produce a significant amount of heat. When turned off, however, the resulting changes in the environment can leave crops more vulnerable to condensation and pathogens as they cool faster than other surfaces.

Under LEDs, the environment is less affected by the heat produced by the lighting, with the most accurate HVACD system, designed precisely for managing the maintenance of temperature and humidity set points.

This improved stability of the LEDs translates to less condensation on the plants, less water usage and less dehumidifying ventilation.

● Achieve the perfect temperature with LEDs.

Ambient temperature plays an important role in the physiological functions and pollen development of certain crops such as cucumbers and tomatoes. With HPS systems, it is much more expensive and difficult to maintain adequate heat levels, leading to fluctuations that stress plants. Although HPS lamps can perform two different tasks — both lighting and heating, they do not perform any task particularly well and pose a much greater danger to plants if they fail. Ultimately, maintaining optimal temperatures should be the responsibility of the HVACD system.

An LED retrofit may require the addition of a heating system, but growers will generally see reduced heating loads overall and, more importantly, will favor greater control of their environments.

● LEDs stabilize CO2, preventing ventilation
As PPFD increases, maintaining supplemental CO2 levels is critical to maximize photobiological responses and overall production. A concentration of 1.200 to 2.000 ppm is often the optimal range for production.
