This is the best aeration amendment I've ever used. Plants drink more steadily and evenly, takes a fair chunk of guess work out of watering large containers. I use 2 parts gs to 1 part rice hulls for aeration, if there's something better out there I haven't seen it.

I use Growstone for orchid growing.
