View Full Version : How do you properly seed a rockwool cube?

I recently sowed many lettuce seeds in rockwool squares. Multiple sprouts came out of each square. What is the proper procedure on proceeding? Should I pluck the weaker seedlings till only 1 is left, or leave them all, or somewhere in between?

when they start to crowd each other buy the next size cube and put it under the small one the roots will continue to grow just like you put it in to a bigger pot .
