That is why Meranti was chosen, it has all the above quality. The pores on it is smaller so the ability of absorbing water is less, therefore, chances of growing fungus is less. Since the pores are smaller, the secretion is less and it is almost odorless. The below is the microscopic picture Dark Red Meranti.
In Peninsular Malaysia , due to the scarcity of Meranti another wood call Bintagor has been widely used as substitute. It's less hard and not as good quality as Meranti but some successful farms have been using it. The durability in long run is a problem.
The above is the Dark Red Meranti that has a good plank quality. Good woods will last many years as we are looking at a long term investment of 5-15 years or more, it would be a big set-back when birds don't build nest or when they build the planks start to have problem (rot). As we know farm is a high humidity environment any woods that can't take humidity is not suitable for planking. Honestly getting Red Meranti in P.Malaysia is not easy unless one knows how to identify it and willing to pay more for it. This due to limited forest areas that allowed timber to be felt. In years to come no area will be allowed to fall timber. This is to protect the forest and the environment
