Hell I cloned a cuts with nothing more than superthrive and pete pellets, worked, rooted slowly though (one took 21 days). I also cloned one in a clear Solo cup with a zip lock baggy rubber banded on to form a dome and the cutting was 3 weeks into flowering with a flower, this also worked. Last 2 times I used Ready Rooters soaked in ph'd water with superthrive, dipped in clone gel and put in clear plastic shoe boxes put together to form a dome.
