Kiwi Bark is made from Pinus Radiata bark from New Zealand. It is a wonderful, long lasting orchid growing medium.
Kiwi Bark comes in:
Fine grade is 3mm to 8mm. It is great for seedlings, miniatures, and those who prefer their growing medium to hold more water and dry slower than larger size chips.
Medium grade is 8mm to 20mm. It is a great all purpose size suitable for use with most genera of orchids.
Coarse grade is 20mm to 25mm. It is great for very large orchids or plants that growers wish to drain and dry very quickly.
