Chitting seeds

How long ago did you sow the seeds, and is the compost heated?

A week may be rather optimistic for seeing seedlings through. I'd suggest waiting a while longer before writing them off completely 

i think they need bottom heat even then a week is a bit soon to see anything good luck.

My advice.... be a bit more patient! 

Any advice about chitting would be appreciated.

Take care to ensure that the paper is not too wet to avoid mould.

I do find that a lot of the white coloured beans are more prone to rotting. I sometimes soak them overnight then put in barely damp kitchen paper and keep a close eye they don't dry out.

I've struggled in recent years with mould on sweetcorn and had fairly high losses compared to several years back. I'm going to try using J-cloths for these this year to see if that makes a difference.

Don't put them somewhere too cold either.

I generally put them in a fairly sealed bag but would be interested to see what others do for this. Maybe some airflow would be beneficial.

Beans and peas, I don't bother with the paper. Put the seeds in a glass jar, add water and soak overnight (or 6 to 8 hours).

Drain.

Gently rinse and drain daily until you see a root starting to develop on several seeds. When that happens plant in the ground.

Tomato seeds....
Tried this method this year and germination was quicker than normal.

Make a cup of Chamomile tea, the tea bag is then placed in a bowl and add hot water, let it soak while you drink the tea you just made. Take the bag out and allow to cool, soak your tommy seed in the tea for around 30mins, give a little stir and any that float dispose them, the ones which sink are viable and sow them, you need them around 24c and they will pop up within a few days. The tea breaks down the coating on the seed so they germinate quicker, used it on all mine this year and very successful and to be honest the tea wasn't bad as well.
The method is on Nettles and Pettles Instagram and he was on Gardeners World the other week.
