How Many Days Until Seedlings Photosynthesize?

When do my seedlings need good sunlight?

I purchased some Beach Pea seeds with the idea I would grOW them as houseplants all year and plant them in the Spring. I failed to take into account the short days in the winter. Also, my window faces North.

The seeds have germinated, and just have a little green thread coming out of the, My plan is to send them to my parent's place once I get them potted. My parent's kitchen has South facing windows and florescent lights.

My questions are:
1.) How many days after sprouting do they need serious sunlight? They are sprouting fine in the light I have...I wonder if they will need more when they start to photosynthesize.
Also, when I send them to my parent's they won't get watered as consistently.
2.) When I send them to my parents, would they be better off on the porch (An unheated room made of windows, effectively an unheated greenhouse) or in the kitchen near a window (a room with with florescent lights and heating)).

They will need good light the moment they pierce the soil or growing medium. They have green leaves, however small, and are photosynthesising right from the start. But direct hot sun would be too much for them.

I can't answer the question about the porch since I don't know what temperatures your plants can take nor what temperature the porch reaches.

keep in mind that beach peas grow in full sun outdoors. if grown in a screen porch, they will not be happy. i have a screen porch and sun loving plants hate it there, even in sunshine. if they don't get full sun when they sprout, they will get leggy trying to reach strong light. a sunny windowsill is better.
