Philodendrons will thrive in environments with medium to bright, indirect sunlight. Indirect sunlight means that the light is filtered through another source before hitting the plant.
Partial or dappled shade is great for this plant, as it mimics the rainforest habitat where it originated. You can use special curtains or even other houseplants to achieve this effect.
Footcandles are another great way to measure light. Footcandles (FCs) are the units used by light meters to determine the amount of sunlight in a room.
With philodendrons, you will want an average amount of 200 FCs, with at least 100 FCs present for minimal growth.
There are several ways to achieve this lighting environment, even without a light meter. If you place your philodendron Atabapoense near an eastern or northern facing window, it will get bright, indirect sunlight for the majority of the day.
Placing this plant in a cluster of others near a northern window will be a simple way to achieve the shaded effect.
