Gib,
I hate to say it but while someone buying bamboo flooring or bamboo
plywood might be curious to learn it is a grass he almost certainly
is not interested in what species it is. He wants to know the product
will do the job and satisfy his needs as a customer. As with any new
product, the seller should be able to answer any questions the
customer has or he will go elsewhere.
