First Grow need help

You are supposed to keep the cubes wet but not saturated. I used a dropper, for this usually a turkey baster, and dribble onto the cube. After a few times you can see how much water they are soaking up and can judge better in the future how much they need. Never squeeze the cube as it ruins the porosity of the medium. You can however use a sharp flick of the wrist t rid the cube a excess water.
