Ok bubblers seem like there the simplest and easiest system to build and maintain. How is a bubbler operated? If built, what exactly is needed to have a plant thrive in this system without dripper rings?
How do i keep a clone growing in it long enough to have the roots reach the water and nute solution beneath the net pot? This is my main concern. Do i put such a high level of water that the bottom layer of the hydroton will be in the water?
