hi alex, i have used this before, and to tell you the truth it didn't work that great.
do a local surch with nurseries about sandy loam, gold fines or decomposed granite (the last is very hard to find and very expensive if you do). perhaps even a loam and sand mix would work well, much better than the peat for sure.
