Should the grow light be on all the time?


Q: If I give the plants light all day, they will grow faster, right? I think all I have to do is keep the lights on and they will become monsters!
Generally speaking, you should not let the plant lights run 24/7. Plants need a light-dark cycle to develop normally. It is believed that they do "rest" during the dark period, and may use this time to transfer nutrients to the limbs and take a break from growth.
Keep this simple fact in mind, and also know that most plants expect to get at least 12 hours of light a day, all light intensities are different. Check your plant guide to learn about the specific sunlight requirements of your hydroponic plants as they grow and bloom.

Should I run my grow lights at night?

Just like the cycle of the sun, there is no need to run the grow lights around the clock. Yes, some plants need more sunlight than others. Therefore, depending on the type of plant you want to illuminate, this will determine when you run the plant light during the day.
A good general rule of thumb to keep in mind is that if your plant is flowering or vegetable, it needs 12 to 16 hours of light a day and 8 hours of dark rest.

Some examples are listed below to illustrate how much light certain plants need.


Plants that require 6 to 8 hours of light

Cherry tomatoes

Plants that require 8 to 12 hours of light

African Violet

Plants that require 14 to 18 hours of light

Little orange tree

Even dwarf citrus trees tend to grow bigger, so they need more space to grow and need to hang larger lights 6 to 12 inches away from the plants. You need to keep the lights about 6 to 8 inches away from the plants so that they don’t burn too close. If you have a variety of plants and some need to be closer, you can support them so that other plants have enough room to grow.
