Weird white stuff in my greenhouse!

Does it look like this.

This happened when i went green and used B&Q peat free compost.  I think the compost was needing a couple of more weeks to break down.



It hasn't spread anywhere but then i haven't moved it into the greenhouse.

I had same problems this year with B+Q compost. been really good in the past but this year as you said it looks like it needed a few more weeks composting.
