rockwool question

Trying to follow Al B model with 40 mm cubes in Ebb Flow. Successfully germinate in ph'd rockwool and about 3 days after sprouting comes the taproot out of the bottom of cube almost 1/2 inch. Now I put cube 1/2 inch above flood level in hydroton and I think I missed the right mark because root is not growing after 3 more days and kind of brown but plant is still going okay with 2nd set of true leaves 1/2 way to their mark. Tips of first true leaves dry. Ebb & Flow has appropriate H202 and is PH'd to 5.8. Cube was kind of underwatered, I think.

Questions.
1. Should I have waited until more roots came out to put into system?
2. If wait longer what do you put your cubes on under the light? Just the Ebb & Flow tray and handwater???

I hate rockwool but am determined...

Thanks.

I put my directly into my DWC setup after 5 days...... the roots were dangling under one of the rockwool cubes before i put it in there... and then it wouldnt grow into my water untill just recently.... dont worry about it.. i think it is normal (except the brown part..)

did you have multiple roots or just the taproot and would you wait for multiple before transfer?

This is my first hydro grow and im not an expert... but moving my rockwool into my netpot after 3-5 days worked out sucessfully for me...

EDIT: I just had 1/6 plants growing a (TAPROOT) root out of the bottom when i originally put them in the net pots... a few days later a second sprouted a root.... today i have 3 that sprouted roots ......
