from my experience many of the plants that have the potential to deliver very high grade need to be grown perfectly to really get the quality out of them. Its easier to get good results with plants that are easier to grow. Don't sleep on ripper seeds, there are many high quality phenos to be found in their collection, but maybe you want to first go for seeds from humbolt seed company (check out their blueberry cupcake, or jelly donutz) to have a high chance of a very successful grow with nothing lacking in the quality department.
