How far below the tip of my clones stem should the water level be? Should I keep lowering the water level as the roots grow down? I plan on taking my clones as normal, dipping them in clonex gel (to prevent embolism). The cloner will have superthrive (drop / gal) and clonex solution for the first two weeks, then superthrive and grow big for the next two. (It is possible I may use grow and micro from CES) Please comment with any issues you foresee.
