I found that instead of planting seeds, i purchased a bunch of Palm Trees for 500$, each time the fruit was ready (approx 3 mins) there was 50$. In total i have about 50 trees, and so every 3 mins i make 2500$ +, Once i have enough money for the house renovations, i will then go back to producing plants so that i can get the other bonuses (100 sunflowers sold)
