Hi Aidan,
since I'm going to receive my first cobra and I'm quite worried (Will I be able to find sphagnum?), please could you tell me if I can avoid using it? Is it possible to treat it like a sarra (50% perlite,50%peat as compost, no sphagnum on the top)? Do you think I 'd better use a ceramics pot?
thanks a lot for your help..
