I did a transplant last evening into some little pots (about the size of a fist) with the fore mentioned soil mix.I went this small for two reasons, 1st its a little chilly in the evenings and I didnt want the pots to take two weeks to dry out, and secondly I am not sure if the mix is still too "hot" for them.
I figured it was time as half had roots popping out the bottom of the rockwool cubes.
This is their new home for a bit, until the real veg room opens up.
No more humidity dome from here on out.
