PARMAX™ Professional Series Hybrid LED Pro Panels excel in two critical lighting fundamentals for plants. First, intensity, the more intensity (quantity) of light the better your plants will grow and the second being, spectrum, as light intensity increases, light spectrum becomes more important.



Not all PAR light (micro moles) are equal. Plants need specific PAR light for chlorophyll a, b and carotenoid absorbance. Like vitamins to our bodies, plants can only absorb a certain amount of PAR light. Darrin Dow - CEO, Smart Grow Technologies

PARMAX™ Professional Series Hybrid LED Pro Panels grow lights made by Smart Grow Technologies are much more energy efficient than standard HID (High Intensity Discharge) grow lights, because they produce the correct light spectrum that plants require. When purchasing a grow light, it’s important to use a light that concentrates energy on the blue and red part of the spectrum, for growth and flowering. However, don’t disregard the yellow and green part of the spectrum. Certain spikes in the green and yellow wavelengths are essential for chlorophyll A and B development as well as the formation of carotenoids, which aid in the process of photosynthesis. During this process, the plant produces energy from light itself. The leaves of each plant possess many functions that all work together to create the energy that is needed to sustain life.

Within the leaves' cells are energy producing factories called chloroplasts that hold all the chlorophyll, which are the light absorbing pigments. There are two types of chlorophyll which absorb different spectrums of light: Chlorophyll A absorbs the violet, blue, orange and red spectrum the most. Chlorophyll B absorbs the violet, blue, orange and red as well but absorbs more of the blue that’s closer to the green spectrum. Chlorophyll also absorbs some of the yellow light but not a significant amount. That’s why PARMAX™ Professional Series Hybrid LED Pro Panels grow light by Smart Grow Technologies emits just a small measure of the yellow and green spectrum in their LED technology. These grow lights don’t overproduce, which creates wasted energy, but they also don’t under produce. That would also be wasted energy because the plant wouldn’t receive enough to be beneficial. Carotenoids are also light absorbing pigments in the plant, but don’t produce the energy themselves. They must pass that energy onto the chlorophyll which then can utilize that energy. Another benefit that Carotenoids have is the protective properties that are used in protecting the plants cells from elements such as ultra-violet light.

Because light is made up of tiny packets of energy called photons, that energy hits the chlorophyll and is immediately absorbed. This boosts the electrons of the pigment to higher energy levels. Those extra electrons are passed on to molecules of NADP (Nicotine adenine dinucleotide phosphate) and hydrogen to form NADPH, which is used later during the photosynthesis process. However, during this process the chlorophyll gave away too many electrons and is now deficit. To fix this problem, the plant breaks apart water into hydrogen and oxygen stripping electrons from the molecules in the process. Oxygen is then released into the atmosphere as waste and the hydrogen becomes ionized and is pushed through a proton pump where it is used in the bonding of ADP (Adenosine diphosphate) and a phosphate molecule. ADP is essentially the backbone molecule of all metabolisms or the flow of energy in a cell. After the bonding process the new molecules are ATP (Adenosine triphosphate) which is the main transport of chemical energy. This entire process is called the light reaction.

As well as a light reaction, there is also the dark reaction that is also referred to as light independent reactions because this process can happen even in the present of light. This is also referred to as the Calvin Cycle. During this process the ribulose phosphate, a five carbon molecule, is stimulated by enzymes to convince ATP to give up one of its phosphate groups. Once ATP gives up the phosphate group it becomes ADP, which ultimately will be recharged back into ATP during the light reaction process. That phosphate group is combined with ribulose phosphate to produce ribulose biphosphate, which then joins with water and carbon dioxide. After the joining of water and carbon dioxide, the molecules become phosphoglyceric acid after it breaks into two identical molecules. Phosphoglyceric acid receives another phosphate from ATP to become biphosphoglyceric acid. NADPH and the hydrogen ion which made earlier are then used to remove the phosphate to provide the energy and hydrogen needed to create phosphoglycric acid or PGAL. PGAL is used to make sugar and replenish the ribulose phosphate stores so this reaction can continue to happen again.

As long as photons of light continue to be emitted by the sun, photosynthesis will always occur by this revolving process. Growers using a space with limited sunlight, or where supplemental lighting to the sun is needed, can now use an led grow light that provides the same essential colors of light that will produce healthy, fast-growing plants. The PARMAX™ Professional Series Hybrid LED Pro Panels made by Smart Grow Technologies offers an energy efficient product that maximizes the correct light spectrum that plants need. Just the right recipe has been achieved to reach this goldilocks zone of the grow light. All the right light in all the right places. Not too much and not too little, just right.
