My beef with peat-free growing bags (growbags are my cheap source of

I have just had some petunia seed come up fine on New Horizon growbag
compost.

Oh damn, I've lost the thread where I was going to say what my peat free
grobags are. But if the person who was wanting to know is reading this ...
they are Miracle Gro Organic Choice.
