Growing Tomato seedlings

[plantmark]

I sowed my tomatoes 20 March and pricked out into 15 cell seed trays. They are on a heated sand bench which I am covering with fleece at night which has maintained an air temperature of 8 degrees on recent frosty mornings.
I intend to plant them in the greenhouse mid May.
Will they be ok in the 15 cell seed trays until then?
The problem I have is that if I pot them on in individual pots I dont have room for them all on the heated bench.

Depending how warm it is, where you are, I doubt that the toms will do well without potting on.
The good news is that they are cool tolerant (unlike say aubergines) and unless you expect frosts of -2C or colder, they should be alright in the greenhouse without extra heat.
Mine are currently on a pallet, unheated. The hotbed is germinating squash, courgette, sweetcorn + growing basil seedlings, cucumber, melon, all the fancy veg.

Thanks Charles. I am in Hitchin Hertfordshire.
What size pot is best?

Should be ok then and say 9cm is good, diameter or each side is 9cm.

Many thanks. When do you plant Toms in the greenhouse?
