To get the little clones out, just grab them gently by their stem and coax them out of the vinyl tubing. When I do it I take off the lid and guide the roots thru the bottom side opening while pulling them from the top.

Sounds a lot more difficult than it is in reality. Sometimes a little root will get damaged but at this stage they are growing roots regularly and if one gets damaged no biggie. Just remove the damage and it will be replaced in no time with no real stress on the clone.

Check out this post to see some pics of clones further along. It is good reading too. I used many of his concepts so far...
