The white LED lights can help succulents grow if you cannot get enough natural sunlight to the succulent plants.
During the times when the sun is shining I try to let as much natural sunlight in through the windows to allow the succulents to get as much natural sunlight as possible.
The natural sunlight is much better for growing succulents and keeping the succulents healthy and thriving.
But if you cannot get enough sunlight then the white LED lighting is a good option to help the succulents thrive and grow.
I keep LED lights on my succulents all the time when there's no natural sunlight coming in through the windows and the LED lighting uses very little electricity so it's okay to leave them on all the time.
