You can root clones with regular water. I have. Dont put them strait i soil they will probably die. Keep in a cup of water on the window sill.
I dont know how broke you are but a tiny bottle of dutchmaster rooting hormone is pretty damn cheap, and if you can spend 12cents on rockwool cubes, you could use water and just keep some humidity domes on them, or plastic wrap. Just keep the air humid.
You might even be better off just waiting, there will be some major new growth from the transplant, and longer stronger shoots cut with a clean razor through a node will definitely root a lot better, with or without rooting hormone.
Hope that helps.
