The product will supply to all over the world, such as Europe, America, Australia,Amsterdam, Malawi,Ecuador, Madagascar.With the extensive development of the LED industry, LED companies are constantly looking for new development outlets, LED grow lights are undoubtedly to give LED companies a chance to be reborn, but despite the prospect of plant grow lights, the development of plant factories still faces some bottlenecks. For example, the early investment is too large, and an artificial light plant factory with a daily output of 1,000 lettuce plants generally requires a relatively high initial investment. Even if the government subsidizes 50%, it usually takes 5-7 years to become profitable. In addition, the planting technology in the era of factory agriculture has yet to mature, and the related quality control, logistics and sales models are also being explored.
