build the whole back row with sunflowers. build repeaters in front in 3 rows. leave one row blank put tall nuts in front of the blanks. then put torchwood in the blank row. upgrade everything asap and in case of emergencies keep cattails and pumpkins for digger zombies and imps. got me through 23 levels! but i would have gotten further but i accidentally forgot about the gargantuars and imps....
