Orchid Bark (Medium Grade)

Orchid bark is an excellent organic aeration medium to add into substrate blends. From fine to large it can be used in bioactive grow bins and chunky aroid mixes respectively, with endless possibilities in-between. We even grow some orchids exclusively in bark. Just be careful not to overwater as water retention is long-lasting and a dry surface in pots can be deceiving. Medium grade: 8-12mm
