I end up read the post after i put my mix in the oven!..
So we will see what going to happen on cuttings :S
I think, by the way, that they are ready for re potting (9 days from the day i cut them) bat i will wait till it passed 2 weeks!
I am a little concerned about my sand on the mix (i wash it loads as you tell me plus i put it in a water and boil it), bat i dont really know if all the salts are out.
I guess we will see what will happen.
