I've heard about this before, you want to watch how much sun you give them and you have to be very careful. You also want to make sure that the branch you use is at least 7 nodes or layers up from the bottom or the branch won't be able to mature into a clone and it will be a waste of time.
thats simply not true.
bottom branches actually root faster than any other, the reason being they have more auxins in them the the newer upper branches. bottom branches are also superior because they have more available carbs stored in there leaves vs newer branches with newer leaves.
there is also a factor called apical dominance, that has alot to do with it... im not going to go into it though. just know that the branch with a lower apical dominance roots faster.
to the OP-
you can clone directly into jiffypots (the self expanding peat pucks), cocoa noir, rockwool, bubble/aeroponically, or just about any sterile medium that will retain water and allow air to reach the rootzone at the same time. methods of cloning are endless, but the trick is finding what method works best for you. some type of rooting hormone or clonex is essential though, untill you understand the process better.
