East or west-facing window light is ideal for most Blushing Bromeliad. However, if the west-facing window is in question, the direct afternoon light may be too harsh for some species, so ensure greater distance from the window or another type of shading during the critical part of the day.
If a south-facing window is your only option, keeping Blushing Bromeliad next to it can be possible if you create some distance between the light source and the plant, plus filter the light through a suitable curtain.
Again, the ideal position will largely depend on the species in question, and you need to factor in other requirements, such as humidity, into the equation. For example, bathrooms are ideal for Blushing Bromeliad regarding humidity but may not secure enough light for many species unless you have a window in there. However, some species may thrive under low-light bathroom conditions with some natural light available and some supplemented by artificial fluorescent light.
Other positions, such as kitchen windows, may provide ideal light but may be too dry. In that case, try increasing the humidity around the plant by creating a humidity tray under the pot or adding a humidifier.
Also, Blushing Bromeliad will thrive outdoors in tropical climates and can be brought out during the summer in warm temperate climates. In outdoor conditions, they perform well under trees with broad and semi-thick canopies that create dappled light conditions. Also, shaded patios and bright porches are also great options.
