Thats as far in as it goes! Am I supposed to pull out the bread like I'm making room for the meatballs?
The 4" blocks and Hugos' normally come with a hole in the middle, ready to slot your starter cube into. This just helps out with watering a younger seedling when the roots are below the fertigation line.
If you can, maybe remove the plug and trim the Grodan cube to make the plug fit. Loose is better than tight, rockwool does not benefit from being compressed. ... If you happen to get a 1-2" main stem, it might be difficult to support.
