It is true that succulent plants require sunlight in order to thrive. However, it is important to ensure that your succulents are not left with moist soil for long periods of time. This plant won't thrive in the shade for long periods of time. I was pleasantly surprised to see that they had survived the winter frost. You can increase the amount of time they spend in the lights if they are doing well. Tube lights are great for covering multiple plants at once and are the best choice for gardeners who have a lot of succulents or cacti.
