Two girls ready to go under the knife for the first time. Also my very first attempt to clone. All shoots are between 4 and 6". All have between 1 and 3 nodes on the shoots..

1.How many nodes should the shoots have before cutting?
2.What is the optimum length for rooting a clone?
3.How close to the main stem should the shoot be cut?
4.How much leaf should remain on cutting?
5.The shoots are as thick as the main branches will this cause shock?

I have miracle grow rooting powder[check] scissors[check] pitcher of water[check] 6+ 1 liter pots with soil[check] cling wrap for humidity[check] and a rusty butter knife[check]

Can someone help me get outta neutral? They're just beggin to go into 12/12
