don't use either. Use fresh aloe Vera gel from a leaf. Or 200x aloe powder. From a leaf is free. Aloe has much better results. Roots in 5-7 days with sticking cuttings directly in soil. No rapid rooters or anything... With clonex rooting in soil takes 3 weeks...pull an aloe leaf place in a cup to drain sap. Snip tip of the leaf. Then dip cutting into the tip of the leaf like any other cloning gel. You can get an aloe vera plant anywhere from $3 -$20 depending on the size... Any nursery, farmers market, home depot, Lowes, trader Joes, Costco, Albertsons, some hydro shops, your neighbors yard.... The beach ..
