    In addition to potential downside of using vermiculite, there is the fact that
    peat moss harvesting is environmentally unsustainable. Even though peatlands occupy only 3% of the Earth's surface, they store a third of the world’s soil carbon, twice as much as forests, and when they are harvested, carbon dioxide is released, the major greenhouse gas driving climate change. Many people recommend coconut coir as an environmentally friendly alternative to peat moss.

    Is coconut coir as absorbent as peat moss? Also, why are you out here posting on a discussion from 15 years ago? I thought I was the only weird one out here reading this stuff.

    Vermiculite Alternatives
    Finely ground pine bark, also called "pine fines," is a principal ingredient
    of most potting mixes. As an alternative to vermiculite, pine fines also
    offer water-retentive qualities, especially with smaller particle sizes.
    Cotton gin waste includes gin leavings, such as stems, leaves and hulls.
    Cotton gin compost renders these waste products into a viable alternative to vermiculite, also because of its ability to increase water-holding qualities
    in mixes. Resembling sphagnum peat moss, coir is the finished product of
    ground coconut husks. The University of Arkansas Cooperative Extension
    Service reports that coir can retain up to nine times its weight in water.

    I usually till in a big bag of peat moss.
