Normally, I run fondant with an inner cover and a piece of sound deadening material above it as my moisture board (normally is moldy come spring). It seems to have worked decently well the last few winters. However, I noticed Dadant has a moisture control box with ventilation and a sliding front drawer to add your winter feed. Looks like it would be less invasive and better than waiting for a 45 degree day to check what fondant is left, which always makes me nervous during long cold stretches. Has anyone tried this?
