From a fellow grower: Gorilla Glue seeds that germinated aren’t growing in the Rockwool. They sprouted a tail a week ago and I transferred to Rockwool and put under a propagation light. I pre-soaked the cubes as instructed. I broke open one of the cubes last night to see if anything was happening. The tail is the same size as when I put in the cube. It’s still white which indicates it’s alive, but it hasn’t grown.
That’s a bummer. I’ve had issues with rockwool before being too wet. I like to fling the cube in an arch through the air to get excess moisture out. Also, are they warm? 80 degrees seems to be a perfect temp for seedlings.
Seedlings need air and moisture. Too much moisture and they drown.
