Sun + Artis

If babies get 6-8hrs of sun per day during flower (direct light), how strong does the light really need to be when I bring them inside?

that dosnt really make since but ill try to fill a couple gaps for a plant to flower in need 12 of light (direct or indirect) and 12 of darkness complete darknes lil lights and light leaks or just opening your door to many time s fucks stuff up and you get a hermie or otha shit. But the strongnest of the light well unless you have some grow light in your house i would just keep them outside.. but just to let you know its almost the start of the season kinda sooo yea there not flowering untill you make them

Ok, more clear,

They get 8 hours of sun a day, then they come in at night, which requires 4 more hours (actually three because they get one in the morning before going out) for flowering. How string does this 4 hours of sup light really need to be?

strong does it need to be?

You should be able to read in the room. Usualy a couple incandescant or fluorescent bulbs does the trick.
