Everything seems very simple: I bought a lamp and hung it up... but it is not.

What is the use of LED lights?

Plant lights are used for successful seedling and greening, but if we talk about powerful professional lights, then they will be used for the full cycle of flowering and fruiting plants.

vegetation. seedling. This is very important during the first few weeks of plant life (vegetation)-the further development of plants depends on the quality of light and nutrients (fertilizers and stimulants). Choosing high-quality lights is extremely important, because this will ultimately determine how much fruit (flowers) you get.

Dothwaite. Many growers believe that plants lack light only in winter, but this is not always the case. Depending on the conditions, the location of plants depends on the amount of light they receive. Sometimes, there is not enough light passing through the balcony or window glass, and there is not enough time for "sunbathing". In order to make up for the lack of light, Groumeer recommends using a small and economical assistant-LED plant lights.

Full cycle. Most of the LED bulbs available in the Groomer store are suitable for all stages of factory development. With this light, plants can be grown in places where there is no light at all.

Many of our customers grow various plants in the attic, basement, bathroom and living room. But the most popular places are planting boxes or planting tents. You can talk about where to grow for a long time, so we will try not to leave the main topic, just a brief explanation: if you do it right, you can not only provide yourself with vegetables, but also provide yourself with tomatoes, cucumbers, peppers, Strawberry etc. For suggestions, please contact the Groomer store.

Sodium gas discharge lamp. (DNaT, DNaZ, NL, NLND, NLVD, curved tubular sodium)-The lamp is the most popular among growers. When planting plants under any conditions, lighting with the help of HPS can bring excellent results: planting boxes, planting tents, greenhouses, but it is not suitable for growing indoors or on balconies-too bright light can hurt people's eyes.

Metal halide. (MGL, DRI)-They are ideal only in the growing season, as they require more yellow spectrum (HPS) flowering light. The HPS and DRI lamps used in factories are expensive lamps that require other equipment (chokes, izu) to be installed. Such lamps have stood the test of time and can provide excellent results, but they are not suitable for illuminating plants on balconies, windowsills or just in apartments without extra special protection. They are suitable for growing in greenhouses, planting boxes, tents and specially equipped houses.

LED. (LED) LED lighting is the future. Many experienced breeders who rely on HPS for their growth are willing to switch to LED lights. Among all the types of artificial lighting that exist in our time, the future belongs to LED lights for plants.
