Okay but if I get carpal tunnel...
I don't use thrives at all any more. They are great for transplanting but I've seen too much trouble with people ODing on their N and making a royal mess. Remember new growth is tender and susceptible to whatever problems you have so encouraging it during cloning is not good. Plus N during cloning, including giving the mother too much 'grow' before cuttings, inhibits root growth.
Start nutes AFTER you are certain that the new plants are acclimated to their environment, and start WEAK.
