Best compost for veg seeds

Can someone please help me with choice of seed compost.
Previous years i used John Innes seed compost, liked it ok but can't manage to get it this year!
Would John Innes No. 1 be a good alternative? I can get that.
I also have some coco coir and Vermiculite,
Could i add that to the John Innes No1?
What would you recommend.

 

J.l seed compost has less feed and more coarse sand in it than J.l 1 , so l would add 10% sand to No 1. Then the only difference would be the feed , which l don’t think would worry most seeds. Personally l would leave coir out of the mix as it holds a fair amount of moisture and could make watering problematic. The vermiculite could be used as a thin layer on top once your seed is sown and covered , to retain moisture .

 

For the past few years I used equal parts of JI No1, own sifted Compost, Coir & a little Perlite, never any problems.
