Multi purpose vs seed compost for veg seeds

Hello I bought seed compost this year and found it better to use. Trouble is through penny punching and a multi buy offer I've now bought multi purpose compost. Went to use it the other day...top layer has white mould/mildew on it. So I scraped it off, filled up my seed trays, but it still stinks of mould! Is it OK to use? I want to sow some brassicas but don't want to waste my time if they won't survive. Thanks! image

    It should be alright sometimes compost is like that,don't make it too wet, I us levingtons multi because it's cheaper get 3 for 2.I take all the big bits out.I find that I get a few weeds in it especially stinging nettle.

    You can fill the bottom of the pot with MP compost, and the top little bit with seed compost, and sow into that.  I like the finer texture of seed compost,.. but you're right, it's darn expensive!  I've layered before when running low on seed compost, it worked fine.

    I've always used ordinary compost, it works fine with good seeds. I have Pak Choi, a cabbage, growing well in New Horizon.

    Mould is harmless, compost can be damp and mould grows, so maybe the mould is an indicator that it is too damp? I've seen that before when the shop stored it in wet conditions. It'll dry out when used. Basically the mould is breaking down any organic matter, which is what happens in composting anyway.

    I usually sow in sieved MPC, this year I bought a bag of Bowers seed compost, it was without lumps but very gritty. The seedlings seemed to have the compost stuck to the initial leaves and struggled to open, I had to have tweezers on some of them.

    I'm back to MPC next year.

    Thanks for replies. I think I'll give it a go then. Just make sure I don't soak them. It's very difficult to judge how much water...too much and there's mould and too little and it dries out and therefore no germination of seeds!

    janetclaireI cover mine with cling film until they start to come up but keep an eye on them every day or even twice a day I find the first one's a bit leggy but the rest will be alright. Only drizzle the water on the compost so it's slightly damp if the cp is too wet you might not need to water until later

    I consider seed compost a waste of money, never had a problem using MPC.
