Rooting

[DankBuds]

I took my WW cuttins 7 days ago today using "Schultz Take Root" cloning powder, 1" rockwool cubes, and put them under four
4' T8's in a humidity dome, there all still very lush and healthy. My Question is this: Should they be taken root yet? Iv read that
they start to develope them at around day 5, is this true? When I shake Them they still seem to be lose and not rooted yet,
anyone have an idea why there legging behind or is this normal? If its normal when should i expect them to start?
Thanks For The Help

7 days is a lil short but I have had them root that fast a few times. Normal time for me was more like 14 days before they start to grow out of the cube.

when taking cuttings for clones, how important is it that the parent plant be fully in the vegitative cycle? 18 hrs or more of light?
