scenario: kitty litter pan for reservoir, slab of rockwool for medium, 4x4 rockwool cube w/ rooted plant in rockwool slab. the slab is elevated about an inch off the bottom of the reservoir to allow travel of the roots.. My question: do the roots traveling around the bottom of the reservoir need to be wet? if the reservoir dries out but the rockwool medium is still moist do i still need to fill the reservoir? this isnt a drip system (yet..) just a fill up and wait til it dries out type thing.. any replies appreciated.

if the roots coming out get dry, they'll probably die...might stay alive though because the rockwool is still wet...I wouldn't know, because I never let roots dry out ...probably better to err on the side of caution.
