Converting Hydra LG to run on Beads

[CigarNut]

Just remove the foam -- which serves two purposes: keeps the water from sloshing and the pores in the foam release moisture faster than the water surface by itself would -- and replace with beads or gel or anything you want. You just need something that stores and releases moisture.

I would not go to the expense of expensive or RH regulated beads since the Hydra itself regulates RH I think it would reduce the overal effectiveness.
