1 day old seedlings in starter Rockwool cubes, need watering advice!

hello people!

im about to start my 2nd grow and thankfully i got 100% germ rate!!!!

now i transplanted them to little 1.5x1.5 rockwool cubes with a solution of technaflora's thrive alive b-1.

i checked today and saw that two of the seeds are starting to poke out of the cubes already!!!

the top of the cube is a little damp but im not sure how often and how much i should water each cube....

i kinda read that you do not want to water too often otherwise the seedlings wont root as fast because they getting all the water they need.

i dont want to kill my seedlings either...

they are under about 120W of cfl lights about 10 inches above the cubes, once rooted they will be moved to DWC buckets under 800W of sweet MH lights

anyone has any suggestions?? thanks

For what it's worth, I've only used peat pellets to start and I usually would give them water everyday because I had a heat pad under them and a heater in the room to keep the temperature up. This caused the peat to dry out a bit and even turn a lighter brown color which makes it easy to indicate they need water. If the rockwool changes color like this also, that could tell you. Hope that helps

i dont tend to directly water them but i spray them half a dozen times a day, maybe a cpl of times a week i'll pour a little on the cube, maybe enought to fill an egg cup
