dOes it matter that it wont get direct sunlight all day long it only get direct sunlight for 3-6 hours/day

in my country there are no weather station so it summer with or without rain the regular light schedule is
6 am to 6:4. Pm day
7 pm to 6 am night ( here it comes the problem it sould be pitch black or does it need to be dark because in the balcony i get some light reflection from other buildigs )
