A seed is coming out of the rockwool during germination. What should i do? Is this ok or is there something I should do to prevent any damage! Please help, thanks!
It’s likely just pushed the seed shell out of the top with the new growth.
Confirm that there is a tap root growing down into the rockwool - if so you’re all good. It should shed the shell soon
Should be fine. If it poked out then below the surface there will be enough root to survive. Plants determine root/stem based on light so its not a big deal.
