I've put 2 seeds each in 2 pots both of cu's and toms, I'll do the same again every 2 or 3 weeks for the next 6 weeks or so.  
I reckon you can't loose that way, mind i dont use super expensive seed. Tend to go for the standard varieties.

I'm still sitting on my hands as i know through experience i'll not gain anything by sowing just now!  End of March will be time enough for me....and they always seem to catch up.
