Made in Denmark since 1969, horticultural stonewool is widely
recognized as an ideal growing substrate. Each Grodan A'Ok Starter
Plug has a pre-formed hole to insure easy seed or cutting placement.
Gardeners simply wait for plant roots to penetrate the bottom of each
A'Ok Starter Plug before transplanting them into a larger stonewool
cube or block. Grodan stonewool is known for its quality, consistency
and performance. This is a single sheet of 98, one-and-a-half-inch
plugs.
