It took 5 days for my seed to germinate. I planted it last night in a plastic cup but soon going to transplant it in a bigger pot when it sprouts. Do I leave the plastic cup outside already (in direct sunlight) or should I keep it indoors covered in a dark place until it sprouts? I'm growing outdoors btw.
Keep it indoors in a dark, warm, moist place. Once it's up, put it outside, let it get a good root base, THEN transplant! If you put it into a big pot too early the roots will be spaced out and loose, if you leave it in the cup and let it grow into the soil you will have a beautiful root base!
