PPFD, or ‘photons per second’, is an important factor to consider when choosing the right grow light. It measures the amount of light that hits the canopy of plants in a second. LEDs and Compact fluorescents both produce green light, but the former is more energy efficient. PPFD will vary based on the distance between the light and the plants. A light hung 12 feet above a plant canopy will produce a lower light intensity than a light that is 24 feet from a plant’s canopy.
PPFD is a measure of photons that hit the plant canopy in a given second
The PAR and PPFD measurements are often confused. Knowing the difference is vital to creating a growing environment that optimizes photosynthesis. Without a clear understanding of light measurement, it can be difficult to design the best conditions for plants. However, knowing how light measurements work will help you choose a grow light for your garden. This article will explain the PPFD measurement and how to determine if your light is right for your plants.
While PPF does not mean much for plants, it’s an important number for growers to consider. It is important to remember that PPF does not include wavelengths that are less than 400nm. Plants respond better to wavelengths above 700nm. That’s why a plant’s sensitivity curve is very important. For example, in the cultivation of cucumbers, a higher PPFD will increase the yield of this crop by 30%.
Metal halide bulbs emit a cool, blue-green color
You can hang metal halide grow lights anywhere in your indoor garden, but they must be located away from dirt and moisture. They should be installed at a distance of four to six feet from your plants, but you can place them above them if you use a raised bed. However, metal halide bulbs are very expensive and use a lot of electricity.
The cool-green color of metal halide bulbs is ideal for plants during the vegetative phase. The light from these bulbs will protect the plant from stretching during the flowering stage. Lack of blue light in the environment can cause plants to overexert themselves and stunt their growth. Metal halide grow lights have a broad spectrum of light and are most effective in promoting a lush canopy for your plants.
Compact fluorescents are cheaper to run than larger fluorescents
Although compact fluorescents don’t have the same lifespan as large fluorescents, they are far less expensive to purchase and operate. These light bulbs use 75% less energy than conventional light bulbs and can last 10 times as long. Furthermore, they produce almost the same quality of light as traditional bulbs, and they only cost $1.50. They don’t produce absurd amounts of heat, so you won’t need to spend money on air conditioning to remove this heat. The bulb starts dim and doesn’t achieve full brightness for about two to three minutes. Using illuminated wall switches may also accelerate bulb burnout.
CFLs are also better for indoor plants than traditional fluorescents. Their lower energy consumption and longer life make them a good choice. However, they cost more to buy than larger fluorescents. If you’re concerned about the energy cost of larger fluorescents, consider buying compact fluorescents. They cost about half as much to buy but are significantly cheaper to run. They also last a lot longer than incandescents, and last around thirteen times longer.
LEDs are more energy efficient
One advantage of LED lights is that they are adjustable. You can control the wavelengths and intensity to suit the needs of individual plants. For example, you can use blue lights to promote chlorophyll production while red lights help to promote blossoms. This flexibility allows you to create a customized lighting environment for your plants, and it is also a lot more energy efficient than fluorescent bulbs. However, LED grow lights are more expensive up front than their fluorescent counterparts, and they require a higher initial investment.
LEDs also come in different spectrums. The Roleadro LED Grow Light produces a proprietary spectrum with wavelengths in the 460 to 465 nm and 620-740 nm range. It also has a spectrum of 6,000 to 6,500 K, which is perfect for indoor plant growth. It also produces enough light to grow delicate plants, including orchids and tropical plants. Plus, you can even grow seasonal vegetables with these lights.
