720~1000nm–– This wavelength is a general infrared wavelength, which has a low absorption rate for plants, can directly stimulate cell prolongation, and will affect flowering and seed germination. Grow Light , Led Grow Light Cob , Grow Light Red Panel , Temperature: Plants have their own suitable temperature for growth, and most of the common plants in the home are tropical plants, so special attention should be paid to the cold snap.

What are PAR and PPFD in LED grow lights

One way to visualize PPFD is to imagine that the sun is “pouring” light onto plant leaves. As the sun shines light on plants, their leaves are gathering energy.

PPFD is a measurement of the amount of light (photons) that the sun “pours” onto plants over time. PPFD is an important indicator because it helps growers accurately measure the light intensity of photosynthesis in the canopy. This is also important because lights that are too close to the canopy can cause burning, bleaching, growth retardation, or discoloration.

400~520nm (blue) – This wavelength can directly develop plant roots and stems, and has the largest absorption ratio of chlorophyll and carotenoids and the greatest impact on photosynthesis. Massive Selection for Led Grow Light Lm301H 6500K - LED 400W Single Bar smart grow light – Topline Optoelectronic , The product will supply to all over the world, such as: kazakhstan, Costa rica, Hyderabad, In fact, organic cultivation is not completely without fertilizer, but what can be used is organic fertilizer: farm fertilizer, mineral fertilizer, biological bacteria fertilizer, etc. after high-temperature fermentation and harmless treatment. Based on the limitations of this fertilization, the growth cycle of plants must be affected, and the current market demand is in short supply, so shortening the production cycle is one of the methods.
