Hello..Hey RIU I was wondering when doing a DWC obviously water is the medium, so as the plants drink the water-should I continously top off the water or should it just get low enough to where to the bottom where only some nutrients are left, then start a fresh bucket?
fair enough, that is what I have been doing-just suddenly I was scared of my method, I mean being that water is our medium should the roots not be submerged at all times? Verse the open air?I start with 5gal and when plant has sucked it down to 1 to 1-1/2 gal I start over.
