what to do with outdoor clones ??

So basically a friend of mine has an outdoor grow operation goin on, and he has 7 clones left over in rockwool that he doesn't need and i was thinking of growing them in my pc planter hydroponics system. The clones are an indoor/outdoor strain, its a really good strain too (hes the type of guy who would only grow with good genetics) So I was wondering if I could take these clones, which have been living in rockwool cubes outside for about 3 weeks, and grow them myself. They are about 4 inches tall and very healthy, I was planning on growing them in 3 inch netpots with hydroton clay pellets. What I need to know is should I take the clones out of this old, weathered rockwool and somehow put them into new rockwool before growing them inside hydroponically ?

well if you take them outta the rockwool you will fuck them up big just put the cube into your hydroton. They should already have a root system starting if they don't they well would be dead. good luck
