If you don't know what drip to waist means, it means that the solution/nutes leav the system to another ress or drain after coming in contact with the plant/rockW and do not recerculate back threw the system, the drippers are providing fresh nutes/water with every feeding. So basicly to avoid the PH flux you can do drip to waist or place rooted clones in hydro rocks with just the roots only. Another way to do it is have a small bubble cloner that uses the smallest net pots and once roots start coming threw just place the whole net pot into a larger one and surround with hydro rocks. Not all people face serious probs with the RW, but many do and just deal with it in drip set ups.
