you can root in nothing but plain water if you want to. Remember elementary science, sticking the potato in water and then a week later, it had roots? Its the same thing. The most imporant factor is the environment. If your clones are bent over lookin like they're dead, then the probably are. They will stand up on its own after about 30 minutes of putting them into the medium if it is taking up water properly. If you keep the growing medium slightly warmer than the air, it will also assist in quicker root development. i have had a clone root in 3 days before. i just bought some seeds of some God Bud, germinated them christmas morning, and by christmas night, they already sprouted so i planted them in some grodan cubes. God Bud spouts on Christmas day...cant wait for my jesus stick. ;0)
