please any1 correct me if im wrong but thats how i think of it.
Correct.

Regardless if you're starting from seed or a cutting, you'll want to start with a 1 inch rockwool cube. Once you see the roots poppin' out of the bottom you can then transfer into a 4 inch cube OR bury directly into hydroton. When I say bury, you barely want the cube below the surface of the hydroton. If you transfer into a bigger 4 inch cube, you're simply prolonging the burying of the cube into the hydroton. Make sense?

Think about it, if you put the seed into the hydroton, it'll most likely never find the support it needs to grow. However, the rockwool will act as the artifical soil it gets to dig its roots into ... hope this helps :thumbsup:
