Tomatoes

Hi I’m new to growing fruit and veg so I’m just wanting to no when should I start my tomato seeds indoors I was putting them in a long non heated propergator if 8 seeds grow do I do anymore or should that be it for summer

I'd wait until early March at the earliest.
They need warmth to germinate and once they're up they need warmth and lots of light.
Once they're up a sunny windowsill is fine in the day, but move them away from that at night as it will get much too cold for them. 

As to how many you should grow, that depends on how much space you have.
I grow 8 in my greenhouse every year and get more than I know what to do with.
Still lots in the freezer from 2020!

Agree with Pete; I usually sow mine on or about 1 March inside will they stay until they go into an unheated greenhouse when I'm sure it's warm enough, usually May.  Any earlier and they get elongated and that's in front of a sunny SE window in southern England.

I plant mine out in the garden around the beginning of June (I don't have a proper greenhouse) so I start mine off in a little windowsill propagator on the dining room windowsill in mid April.

Mid March for me - just on a windowsill, and they go into the greenhouse around Mid May or so  [can't grow outdoors here] depending on temps.
No need for anything else to get them germinating, and the earlier you have them growing, the more heat, and potting on, you need to keep them going until they go outside or into a greenhouse.
They'll tend to get very etiolated if you start them too soon. It's light they need most at the early stages, which we don't get as early as more southern areas have, so your location is a factor.

Depends where you live,and what facilities you have once they are potted on,and how many you intend to grow. I start mine off late January/ early February. North facing kitchen window sill, quarter trays. Usually about 6 different varieties,then into a frost free green house. I live in the SE UK 10 minutes from the sea.last year was an exception because of unusual late frost. Ended up having to pot them on several times and keep them in the conservatory.

End of February for me in the Midlands,  but then I have a bright south facing conservatory to grow them on in. Then it's into a cold greenhouse in late April early May depending on frosts.

I'm in the north of England and sow mine on the first day of spring so late March. I've experimented with earlier and later but I've found that's the best time for me.
