Did I need to size up to larger rockwool cubes?

Id have let em go a few more days at least before going into the bigger ones, if you cant see any roots poking out at all from the smaller cube its first in, there is no need to go up in size yet, but in saying that, goin up to a larger size a bit soon isnt the end of the world, just means you man need to occasionally water from the top if you think the plants roots are not growing deep enough to reach the water- like you see wilting even thou the cube's base is in water or you see the top half of the cube drying out. it will be fine either way so just be a touch ,more careful with watering for next 7-10 days til the roots are nice and long.
