No matter where you placed your Christmas cactus, make sure that when it is a dark time, it should be dark. No light should be introduced to the plant. If this happens, the blooming cycle will be destroyed, leading to the plant having difficulty flowering.

As you have learned, the Christmas cactus needs a specific set of lights to survive. Here, you will know the difference between direct and indirect light.

Light can only be considered as a direct light when the light rays from the source directly hit the plants without any covering or filter.

Now, there is another type of light that some plants need. It is called a partial shade. In simple terms, it refers to a type of plant that needs direct sunlight for a specific time and then becomes shaded for the rest of the day. 

For example, some plants need at least 3 โ€“ 6 hours of light. Some areas can have this type of condition where during the morning, light comes visible and only sunny during that time but not the rest of the day.

For its benefits, sunlight is the optimal light perfect for growing plants as the wavelengths in there cannot be replicated by artificial light. Furthermore, it’s eco-friendly since it’s renewable energy and cost-efficient.

Now, for the important question, is direct light applicable to Christmas cactus? The answer is NO. Direct light is harmful to this type of plant.

Direct light cannot be controlled, and once it hits the leaves or the flowers, it can burn and destroy them. So avoid using this at all costs.

There are a lot of sources as to where you can get it. To name a few, these are sunlight, which passes through medium, moonlight, and LED Lights.

Indirect Lights have their fair share of benefits like adjustments and control for the strength of light energy plants receive, especially if plants need indirect light; cost-efficient as you may use the lights outside and inside the house as a source provided that it has a medium it can bounce of and perfect if you are creating indoor gardens.

This is the perfect type of light for Christmas Cactus to consider. They are inclined to survive using indirect light but make sure that it’s bright enough for them to receive the needed energy.
