Real money or game coins? To get game coins, you should grow the most profitable crops you can manage. Use the chart on the seed page to see which ones offer the most profit margin or profit per hour, and pick the fastest money you can manage. When I'm online I leave it in background and grow quick crops like raspberries. But my husband only checks it once a day, so he grows crops that take at least a day to mature - things like soybeans and grapes.
