I have these Areca Palms and White Birds of Paradise, in my Apartments patio door window, but they only receive this direct Sun in the Morning Hours! and the one's on the Left! only get that fall off Light, because of an arch in my buildings architecture. I'm wondering if this is an adequate amount of Sunlight for these type of Plants! .....I know I could move them over at night! but they are big and not exactly convenient to move every night!
