I have used Pro-Mix HP for many seasons, I have tried a few others but have never been satisfied and have always returned to PM-HP, the amazing drainage is in perfect balance with moisture retention, and the mix remains airy providing great oxygen capacity, it's very hard to over water when using PM-HP, the roots thrive with the in this airy mixture with the added Mycorrhizae! It is the perfect base for adding amendments or creating living soil, I generally use 80% Pro-Mix HP, 15% worm Castings, and 5% Compost. The Pro-Mix HP is compressed into a 3.8 cubic foot bale and loosened up into 6.5 cubic feet. I pay around 35 US and get about 30 3-gallon buckets out of it.
