Yup, PPP yeilds well for 2 reasons: She's forgiving and easy to grow, so even a n00b should be reasonably happy, and someone with more experience can get some REALLY nice results in a from-clone SOG setup or even training a from-seed plant to a couple leads (3-4ish) per square foot.

Edit: 10 beans- 10 gal buckets- 2k? It's going to take more than a month to get the plants to the point where they will be properly utilizing that light and soil volume.
