I typically take about an hour of it a day, how much do you take?

I try to give my plants a lot of it, but the earth has rotated around it's axis and now the sun doesn't shine in my window in my dorm anymore, so I have to leave them out in the window in the hallway after about 4pm when I get out of class so my four-o'clocks (lol!) get some sun.

But of course last week it was cloudy the whole time so they only got one afternoon of sun (they turned such a bright green the next day though! and a lot taller!), and now that I'm at home for the weekend, it's sunny and they won't get any (nor any water )
ANYWAYS I CAN"T WAIT UNTIL THEY GET BIG.
