Sure, there will be a curvy line on a graph, and the line will go higher and lower, so you might think that the taller the line, the more light there is of that color. Interesting information. “HPS” bulbs were meant for street lamps, and they turn out to be great for flowering, but lack the proper amount of blue light to keep plants compact. Each “veg” and “flower” spectrum is so different, plants will grow differently from light to light depending on the ratio of red, green, and blue light. Available lumens is just as important. This not only means “PAR” is insufficient to measure how light will help plant growth, but it also tells us that plants care about the reactions between multiple colors at a time, especially those in the Infrared range. Thank you! Since your eye can’t see them very well, the LED’s spectrum is designed to leave those colors out. It offers an area of 90cm x 90cm growing for 80cm x 80cm in bloom.

Really nice to find this well ….Seminar really Built with the company’s unique wideband LEDs, the full spectrum light emitted gives full canopy penetration combined with specialized linear optics which allow for wider coverage. Others say colors with a greater red spectrum is better for vertical plant growth while blue is better for horizontal growth. KISS! I want to grow salad greens indoors. It can give your plant a long and healthy life. Notice the word "available". You could say that a plant has a natural way of growing (with infrared) and an unnatural way of growing (without infrared). Plants can sense the % ratio of blue light they receive to determine how to grow. It occurs to me that there remains a lot of refinement to be made with newer and emerging technologies and methods. You are saying 4000K is best for full cycle, but I dont want flowering. Plug in the dimensions of your space to find out! How will this go? Recreating what the sun does naturally, manipulating light creatively, and artistically designing lighting to reproduce natural conditions is an area of research and development where methods have been limited by the technologies themselves. To me, at least, seeing in my short lifetime, a transition from the ubiquitous mainstream incandescent and occasional though mostly commercial florescent lighting, which went on to CFL’s once smaller tubing needed could be mass produced to house it’s modified design of florescent lighting, and now seeing the majority of lights of all kinds being replaced with LED’s, which are of near overwhelming variety and distinction, not to mention with new improvements and advancements refined and brought to market constantly. All White LED spectrums do not take plants into consideration, so blues, greens, yellows, reds, and infrareds can bounce all over the place as they shift from “cool” to “warm”, and can adopt color ratio combinations that are not ideal for plant growth. Contents. As one would expect, is most definitely on the "cool" side when compared to typical warm white lighting options, but is also on the "warm" side when compared to daylight color temperatures. $129.00 $ 129. Remember, plants look for a ratio of color within the spectrum. Browse our collection of articles, how-to's and guides on various lighting applications as well as in-depth color science articles. A 5000K LED bulb produces a bright daylight kind of color. About 90% of the light and electricity used by those bulbs will be wasted, because it's not the spectrum of light the plants needs. See how you can dynamically create your own light spectrum with the FiveSpect™ platform, Learn how we utilize innovative LED technology to achieve an unprecedented 99 CRI rating, Plug in your own SPD to calculate the resulting CRI and individual R values, Browse our extensive collection of LED lighting related articles, Learn more about Waveform Lighting and our approach to lighting, See what our customers say about us and our products. This is why at the Green Sunshine Company we measure our Electric Sky Wideband Grow Lights in what is known as “Extended Photosynthetic Active Radiation” or EPAR for short which measures the full range of light between 300 and 800 nanometers of light. Since neither is perfectly balanced for all stages of growth, we’re in the mantra of “switching” the spectrum from veg to flower. Waveform Lighting offers a 30-day free returns policy. So, it’s good for bathrooms, basements area and your study room. Mike Penn, Exlenvce 1500W 1200W LED Grow Light Full Spectrum for Indoor Plants Veg and Flower,led Plant Growing Light Fixtures with Daisy Chain Function (Triple-Chips 15W LED) 4.6 out of 5 stars 1,586. LEDs, being monochromatic sources and being available in wide range of pure colors, are the only light sources that can be tailored to give right spectrum & do wonderful things for plant growth. Maybe the spectrum will grow way too stretchy, or maybe it will have too much blue which  stresses out the plants and stunts growth, or maybe not enough green and infrared for canopy penetration… you get the idea. ... Make sure that the color of the LEDs (in Kelvins) are in a mid-temperature range. You may have seen Kelvin (K) or Color Temperature (CCT)  before: Have you wondered how lights designed for eyes could somehow work the best for plants? Go higher than 5000K, and so much red light is left out from the spectrum your plants will grow slowly and without much vigor. Plants have been growing for eons under the sun, but we humans haven’t been very good at understanding how light affects plants. Some people prefer 4000K for flower because of terpene production and node spacing. Kudos to you! Go any lower to 1000K, and the … Newer and less cost prohibitive technologies with more efficiency, greater variability, and better quality, can support tremendous innovation. But that isn’t true for plants. However, these colors do not emit bright light and would have a low lumen measurement. In this article you’re going to learn how to think beyond color temperature for plants. Kelvins – color temperature Most fluorescent tube lights have a correlated color temperature (CCT) from 4000K to 6500K, as they have been considered to be most suitable for retail and office environments, respectively. So yes or no should I just go 4 a warm white Led. A 4000K LED bulb produces a bright white or cool toned kind of color which gives a warm effect as well as bright enough to work beneath it. These cheap LED grow lights can be obtained for under 200 bucks, and usually cover about 2x2 feet each. He uncovered a discovery that plants use color from 400nm – 700nm. That has always drawn my interest. Make sure to look for this when buying any type of horticulture lighitng. ECO Farm horticulture led grow lights with Samsung LM561C, 301H or 301B chips could enrich both crop quality and harvest. 4000K is a nicely balanced color that will provide the blues need for growth and the reds required for flowering. A 400W LED grow light will cover a 2.5 X 2.5 ft space. If you’re want to know even more about light, you won’t want to miss out on this video. Overall, you'll just be running up your electric bill for the most MINIMAL results from your plants. See how both CFL and LED Lights might look similar to the human eye, but the red and blue regions are drastically different, meaning different results with plant growth. They are efficient and provide all the necessary wavelengths at a fraction of the cost of dedicated growlights. I have a 4k LED from HLG im not using. With twice the output of standard T5 bulbs and a neutral spectrum, the HLG 65 is a fitting alternative to smaller fluorescent fixtures. I don’t water it much at all (per their instructions) so I would like to get a small grow light for this corner of my home, but would prefer knowing what would be best. Using LED lights allows for optimal CRI ranges that can not be reached with conventional lighting.
