Can I germinate seeds on big rockwool cubes?

  1. Hi!

    All the guides that I found on the internet start with smaller cubes and then transplant to bigger ones, but I only have 4x4'' rockwool cubes (big ones).

    They do come with a small whole for a seed, so is it ok to germinate seeds on them? Or should I get smaller ones and then transplant? Are there any downsides to germinating on big ones?

  2. Dude yea its fine
