It really depends on your situation. I would say 2-4 (so around 3) weeks after germination before moving them into DWC. They do not need nutrients as young seedlings and are fine in the rockwool/RR/jiffy pellets. After week 3 or so (you will have to determine this for yourself), move them into DWC with your diluted nutrient mix to begin some serious growing.
