These trees are very susceptible to stress as stress causes the fruit to drop. So seediness of fruit is a function of the type of fruit, rather than the gender of the fruit. About three years ago, I planted a couple of orange seeds into a plant in my room and now they are all about a foot tall and look healthy. Full sized orange trees make a wide, roundish bush at least 8 to 10 feet tall and about that wide. So not only is space a limitation, but also sunlight.
All fruit plants require full sunlight for optimum tree growth and production.
So the light inside the house would never support that kind of growth either. As you step them up put them outside in full sunlight and allow them to grow to fill the container. Once they become root bound then they need to be transplanted again ending with a container about the size of a wiskey barrel. Be sure to include a slow release fertilizer in the media and water on a regular basis. It would be good if you included a water soluble fertilizer every month.
