Bunny Ear cactus would prefer to have bright indirect sunlight at least for about six hours in general if you grow them in outdoors.

If they run short of sunlight, it will be difficult for them to grow. Consequently, it will make the stunt growth of the plant.

On the other hand, if you add them as indoor plants, I recommend exposing them for about 14 hours of sunlight.

In case you find it difficult to provide sufficient sunlight, you could provide them with artificial sunlight to supplement.

They will be more like natural sunlight for them. For example, fluorescent lamps, fluorescent bulbs , LEDS would be great artificial lights.

Before we proceed further, Bunny Ear cactus belong to the family Cactaceae. You could easily identify them by their segmented pads as it is one of their main highlights of the Bunny Ear cactus.

In fact, those segmented pads mimic the look of bunny ears. Further they will be covered with bristly hairs which you could call glochids.

They are endemic plants to Northern Mexico. They would grow up to 16-24 inches when they are fully grown. Polka dot cactus and angel’s wings are some of the common names of them.

Having said that if you need to supplement the plants if they get low lights, you could grow them under grow lights.

Moreover, you could commonly experience this condition during dark rainy days. If they run short of sunlight for extended periods, it will make them etiolated.

Medium light

Bunny Ear cactus will grow well if you expose them for 6 hours of bright indirect sunlight when you grow them outdoors.

Moreover, the white fluorescent light would be the best option for them, and you can make use of it for about 14-16 hours on a daily basis.

Incandescent lights
