Glad to see you made one! They truly are the best way to propagate most things that are difficult to root. If it will even root an Echinacea cutting, then it's a good thing! LOL.
Don't believe all that crap about "water roots." These plants are ready for planting really soon after those roots appear. I have even let the roots get over 5-6 inches long and then potted too. Roots are roots. Period. I haven't lost a single plant that was rooted in my EZ Clone machine. You just need to be careful when planting them, but once you get used to it, it is all easy. You will not ever want to go back to rooting them any other way. No wilting and suffering and losses. It's practically 100% success for Hibiscus cuttings.
