Hi, Kim. Indirect sunlight simply means that the area receives light from the sun but not the direct rays. I call this bright, indirect light. Really, the only exposure that can be harmful to most tropical plants is the afternoon sun from the west. That's especially true in the spring and summer months. Direct, early morning sun in an eastern and southern exposure is great, and very late, direct sun in a western exposure is fine. You just have to watch out for the sun between 11:00 AM and 4:00 PM during the spring and summer. The sun gets further and further down in the southern sky during the fall and winter, and even direct west sun might be OK during those months. I prefer an eastern exposure in late spring till fall and a southern exposure during fall through early spring. A northern exposure supplies very little light, and though tropical plants might live, they probably won't have lush growth or bloom.
