I am wondering if you can just put 1 week old seedlings in one inch cubes on top of the larger slabs of rockwool? The roots should then just head straight into the larger base?
Or do you cut a little hole in the larger rockwool slab?

cut a hole.

you can just set them on top, but if they get bumped, the roots can break....GL

thanks friendly people - great website

Thanks Funk, gl with your grow...

If I can hijack......

I know to pre-soak the cubes with properly pHd water. But can I do this ahead of time, and let them dry out and then use them right away, when needed?

i would like to know as well, since what i have done in the past is put my rockwools in a 50 gallon container and just fill it up with water. i would think you would cant let them dry out and you need to resoak once they do dry out????

Cool! So I'm not the only moron that has thought this.

I have not needed to wash or soak cubes and worked fine - maybe not that important?

It is best to use them once soaked. I soak mine in Grozyme. As long as it is fully saturated but not dripping you are good to go. Sometimes I soak mine overnight. If you let it dry out, the enymes or whatever you added may deplete and you will just have to soak them when you want to use them again anyways. So only soak them once before using, lol.
