duckfan,
Thanks, but this has been a collaborative effort of many folks here on Tomatovlle. The next "Group" focus will I hope, be on tuning the best combinations of potting mix, bark fines, perlite, greensand, and other available ingredients, to come up with a combo mix that keeps the plants green and productive throughout the Season.
Perhaps a bit too much to expect, but with several people here running various trials on mix combos, we will get it optimized over the next few years. Post some photos when you get a chance, and keep us updated on both good and bad experiences. That is how we all learn over time.
