The answer depends on a few factors, such as the type of Grow Light you`re using, the growing environment of your plant, and the type of plant you have. However, in general, grow lights need to be on for at least 8-10 hours a day. If your plant needs light all day, then it`s best to choose LED grow lights.
We recommend that you place a grow light above the plant since plants tend to lean towards the light source, so it`s best to place it above them. Additionally, grow lights emit heat, so make sure that your plants aren`t touching the grow lights or too close because it can cause leaf burn. Also, if you have low light indoor plants, choose less powerful grow lights. However, if you have large indoor plants, opt for LED grow lights since large indoor plants need lots of light to grow well.
Lastly, it`s best to use a timer for your grow lights. It will be convenient because the timer will automatically turn on or off the grow lights according to the times you set it up.
