seedlings in rockwool

what should the PH of the water be when i spray seedlings in rockwool? because i heard youre supposed to soak the cubes in 5.5 if u want to germinate seeds in them, but once there are seedlings growing, do you change the PH or is still 5.5?

is it in Hydro or soil?
If soil you can go back to the PH for soil which is like 6.2-6.8, if not leave it at the 5.5 if in hydro.

Always keep it between 5.5 - 5.8 all the way through the grow for hydro.

i am going to use soil but right now the seedlings are just in cubes, sitting under some t5's with a fogger on.

there are already roots poking out from the bottom of the rockwool but i want to wait a lil longer before transplanting them

good idea, flip back through my journal and you'll see i wait untill the roots look like they are gonna blow out the cube. They can survive for a good time in the dome, in the cubes, but make sure you keep the cubes moist enough on a regular basis.
RW cubes dry out alot faster than soil plugs, so they may need misted more often than the soil plugs, but not too wet.
How close is the t5's?
