mould on germinating seeds

That sounds like damping off - better drainage and ventilation is needed.

I'm not a fan of coir, especially on its own.  I prefer to use a loam-based seed compost or MPC, both with the addition of  grit/perlite to improve drainage and keep watering to a minimum.  The surface of the compost should be almost dry. 

Also if you're using heat to germinate, remove the seed trays from heat virtually as soon as germination has taken place.

    Fully agree with Dove, seed compost is the way to go, either bought, or home made.

  • MPC = multi-purpose compost - I put it through a garden sieve for all but the largest seeds.

    Don't be embarrassed, everyone has to learn. We've all done it.

    I find seeds will germinate in anything, gravel in your drive, piece of wet kitchen roll, you don't need anything expensive to germinate them. its what you prick them out into that's more important as long as you have a good air flow and draining compost.

    You could be better off if you waited a bit until March when the weather should be a bit warmer, don't know about drier, but just make sure there is plenty of air getting to your seeds and they are not wet.

    Hi aym280, Wisteria grown from seed are notorious for taking many years to flower, up to 20 years. 

  • I agree with Lyn and Dove, never had much success with coir. I sow clematis seeds now on top of about 2 inches of John Innes Seed and Potting, then a good inch of horticultural grit on top. This is after I noticed how many clematis seed germinate and make good plants, on our gravel path.
