Good morning, I usually cover seeds with a fine layer of compost, but Carol Klein recommends grit - do any of you have a strong opinion about this? Tia

grit looks nice but it is too expensive.

I use vermiculite because it retains moisture without becoming soggy. Vermiculite under seeds like petunias works very well.
