I see a potential problem with your plants, that is other than the fact that they need to be light proof around the roots.

It looks like many clones have been cut before the new growth has had a chance to grow. In fact I barely see any new growth tips on some of your plants - it looks like basically just fan leaves. Fan leaves will not produce a bud if you leave them in there 10 years. They will root though, but not as easily.

I don't know if you have ever taken cuttings before, but I make sure to take a more established sample than the ones you have shown. They should be fully rooted and ready to plant in anywhere from 5 to 15 days. You should definatly see root bumps within 5 or 6 days. If not, something is probably wrong.

Keep the light out.

Don't saturate the root area. They will do much better if they have to search for water. I keep mine on all day the first day, than 30 minutes on and 45 minutes off. Mine are usually ready to transfere to their pots in about 10 days.
