This is a first for me. I've grown cuttings with some luck in Rockwool before, but my luck with seeds in the cubes has exceeded my wildest expectations. To begin with, I've kept the seeds/cubes covered with that new sticky plastic wrap. I lift a corner quite often to peek in. Sorry, it's a problem I have, I just have to watch the progress. These were planted about a week to ten days ago and there are several crosses in this mix. This started out to be a test just to see if it would work. I think I know how I'm going to grow my seeds from now on. I'll let these stay in this container until I can see roots coming from the bottom of the cubes and then I'll transplant into my next size up pots.
