The suggestion of 40%-50% RH is just that a suggestion - based on circumstantial evidence that mold can grow in environments where the RH is greater than 50% (won't necessarily hurt the wood but case and pads are the concern). In the old days when Grenadilla wood was air dryed it was stacked and allowed to age in wharehouses in regions of the world where the average RH is around 40% to attain the steady state before manufacuring. Nowadays the process may be in some cases accelerated by heat and vacuum "kiln" drying but the final product ends up in a similar condition at about 40% RH. Below 40% RH will promote water loss from the wood and shrinking - albeit slowly, and greater than 60% - 70% will promote slow water gain in the wood and swelling. Grenadilla wood gains and looses water slowly because of the oil buffering capacity of the wood which moderates water gain and loss but many have experienced shrinkage in extended dry environments. So, IMHO 40% -50% many be a good range to maintain.
