Sorry I haven't been on much. I've just quietly been watching my collection grow without posting much about it. Here are some recent pics if anyone's interested:
My question is this - what exactly is vermiculite and why do I need it? I had been buying my potting mix online and mixing it 50/50 with perlite, but I ran out and don't feel like buying more.
