when the roots start to grow out of the rockwool cubes...place them in netpots backfilled with hydroton, and you will be set.

Also, before you post attachments edit the size to 1mb or smaller...I like 640x640 to 640x480. they load faster and fit the window perfectly...If you load to big of a pik...It will take forever to load, especially if you have dial-up. peace
