有冇人用過white peat?

我有位朋友在學校負責園藝組,園藝物料中有一大包white peat.這植料不像我常用的peat,white peat是long fibre,我從網上找到的廣告:"Grower Grade White has a fibrous consistency that improves aeration and increases drainage to promote plant root development."
想問各位有冇人用過white peat?係唔係真係咁好用,講到好似好用過peat,又improves aeration and increases drainage.
