300W grow light full spectrum dimmable
The 300W dimmable grow light is a type of lighting used for agricultural planting, which can provide 300 watts of light energy. This lamp can be dimmed, meaning that the light intensity and light time can be adjusted according to the needs of different plants to meet the growth needs of plants.
The main purpose of using plant lamps in agricultural planting is to provide the light energy required for photosynthesis to promote the growth and development of plants. grow lights can provide light in an indoor environment, so that plants get enough light energy to grow normally even in the absence of natural sunlight.
300W dimmable light grow led usually use LED technology, which has the characteristics of high efficiency and energy saving, long life and good stability. It can emit specific wavelengths of light, such as blue and red, which have important effects on plant growth and flowering. By adjusting the light intensity and light time of the lamps, the light conditions of different seasons can be simulated, thus promoting the growth and flowering of plants.
300W adjustable light plant lamp is widely used in indoor planting, greenhouse planting, plant factory and other agricultural planting fields. It can help farmers in the absence of natural light, provide enough light energy, promote the growth of plants and improve yields. At the same time, the dimmable function also makes the lamps more flexible and can be adjusted according to the needs of different plants to provide the most suitable lighting conditions.

The first is to mix "gas and fertilizer" with farmyard manure. When planting potatoes and sweet potatoes, mix 20-25 kg of ammonium bicarbonate per mu with farmyard manure and apply it to cultivated ridges to drive and kill the mites that are harmful to the seedlings. Before planting vegetable seeds and seedlings such as amaranth, garlic, cowpea, cucumber, etc., use 25-30 kg of “gas fertilizer†per mu and mix well with farmyard manure to kill roots and small tigers and alleviate the damage of these underground pests. .
The second is to dilute the “gas fertilizer†and spray it on the foliage of the crop. When melons and fruit vegetables are aphid, the "gas fertilizer" is diluted 80-100 times, and evenly sprayed on the stems and leaves of these crops with a sprayer to kill the aphids and reduce fungi, bacteria and viruses such as blight and verticillium. Sexual diseases.
The third is to use ammonium bicarbonate or copper sulfate as raw materials to make pesticides. Using 3.8 kg of ammonium hydrogencarbonate and 0.5 kg of copper sulfate which was ground into a powder, mix well and immediately add 1 kg of lime to mix well, and put it into a container or a gas-tight nylon bag for 24 hours to form "copper ammonium powder". When used, the copper ammonium powder is diluted to a "copper ammonium mixture" by adding 1200-1500 times of copper content. Spraying vegetables and cotton not only can prevent fungal and bacterial diseases, but also has the effect of topdressing.
"Gas and fat" can be used as pesticides
"Gas and fertilizer" is the nickname of the farmers' friends for ammonium bicarbonate. It is a chemical fertilizer with nitrogen content of more than 17%. It can not only provide nutrients for the growth of crops, but also be used as pesticides to control many diseases of crops. insect. When pesticides are used, the method is as follows:
