if i had to either have morning sun for 5 hours or afternoon sun for 5 hours, i would go with the morning. the dew on the buds in the early morning will need to be dried by the sun to prevent mold and bu rot. if your plant was in the shade untill 11 or 12, then that dew and moisture will be covering your flowers increasing the probability of mold. 5 hours of direct sunlight is doable. mine rarely get that. peace
