How to Grow and Care
As with just about every cactus, a lack of light will really harm them if you expect growth and continue to water them. You will wait for a long time if you do not have an artificial light source and humidity. Pereskiopsis live in very tropical, wet and humid regions of Central and South America. This is easy to recreate with your grow light and indoor greenhouse set up. But you must be careful to allow air circulation. This is one of the number one killers of Pereskiopsis in general behind overwatering. If you have an indoor greenhouse you can easily do this by opening up the tent for several hours a day and choosing one day a week in which it is open all day. You should have 2 angles for air circulation to navigate. No artificial fans need but can be helpful.
These cacti have the unique property of wanting more water. Don't make the common mistake though, most cacti would prefer if you watered them more. However, the soil, heat, and light that you have are probably not enough to accommodate them. Even in their natural habitat, cacti would prefer more water than they receive.
