I should be saying I'll move plants if needed the other such as my dragon tree can take that direct light all day but I don't think my devils ivy needs that much ? Correct? And the Cassandra and pinta would need the cfl light for 8 to 12 hours a day ?? What about the newly potted Persian shields? I grew them in full sun and very warm shade they loved it! I don't really know .. how do you estimate the time each needs in the sun ? I have searched this question so many times and I guess there is nothing but per plant. But I don't know all of them so it's harder to figure out starting with what they like outside.. I can't wait to figure these things out. Lol I love talking to you all here but I hate asking same things over and over and frustrating others. Lol
