It's hard to visualize your bottle set up without pics so I can't comment on that. If it were me I'd like to have more control over the lighting and temps. Some folks don't seem to know you CAN clone during flower although late flower is less than ideal.

White fuzz? I hope it's not mold. Maybe you just mean the hairs?

Here is a link to a recent thread with lots of good tips and also has a link to another thread with more tips including a lengthy and detailed post about cloning from yours truly. Searching this board, google and youtube should give you the idea too.
