she helped me gather charcoal, those used for bbq and kept them in an airy bag. using that as moisture sucker. she says it works wonder and last much much longer than thirsty hippo which eventually turns into liquid. i wonder if anyone uses this method as well. im a newbie. but it seems that the curboard really feels dry inside. the size of the cabinet is about say, 1 and a half A3 size paper?
