Best and worst seed and potting compost

Hi
Does anyone know the best potting/ seeding compost available? I've been let down several times with popular top brands of potting and multipurpose compost being full of large hard woody bits totally unsuitable for seeds and seedlings. The worse I got last year was from lidls and wasn't much different from bark chippings despite being advertised as potting and seeding compost on the bag!

Ideally I want a fine spongy but well drained compost. I find John Inness 2 to lack the sponginess and be a bit too easy to dry out.

I've seen the professional grade composts used by nurseries and market gardens and they are ideal in every aspect. Spongy, well drained, fertile and fine.
Does anyone know any brands available to public that are like this?

Thanks

    Verve from b&q is the worst I've tried.

    In London. Keen but lazy.

    seed compost plus added perlite works fine for me.

    Some annuals just get sown in MPC, as it is cheaper.

    I think that the key is low fertility for seeds.

  • Glad to hear about Wyevale compost - just bought some, not opened it yet though!

    Hazel, we're allowed to give recommendations regarding products, so long as we're not promoting something we're involved with selling.

    I think that's the distinction, but I could be wrong.

    Fot seed sowing I generally use a mix of John Innes seed, MPC and a fine grit I get from the fish shop because I can only get coarse grit from the local GCS.

    never heard of it Hazel. image

    I have to be honest, I buy whatever is on special offer and make allowances as things grow/ don't grow as the season moves on. 

    I've never had any disasters  nor found a miracle brand.
