The donut float worked great; I bought it from MainlandMart.com along with the single-head fogger, some time back while attempting to build an aeroponic fog grow system. It worked fine with plain water, but with nutes it clogged way too easily, way too fast. Not sure how nutes / additives that would help in cloning, if you choose to use them (such as Rhizotonic) would go along with it for any length of time.
