Having read through some of these posts I am beginning to wonder what the point of a greenhouse is?  As it gets very hot in one even the plastic one I have (and it is only spring temperatures)....  Everything might as well be started off on windowsills in the house....

Everything might as well be started off on windowsills

yes you can do that, but i find i very quickly run out of window ledges I think that at the moment some people are sowing things in the greenhouse that do not need heat

But for me a g/h means i get a better crop of tomatoes and peppers, cues and aubergine
That's all

Greenhouses also extend a season - last year my outdoor chillies & peppers were so slow to ripen and then it started to get colder outside and I wished I'd had a greenhouse for both the warmth and a little extra time.  Then there's some winter cropping of salad leaves etc, and how about some potatoes then too?

And remember that a greenhouse has roof vents and wall louvres to allow air to flow through them.

I agree........ i do use mine through the winter for salad and other stuff but i only bought it in the first place for the toms Lots and lots of toms

And remember that a greenhouse has roof vents and wall louvres to allow air to flow through them.

If you're lucky...depends what you can afford! Mine has 1 small sliding window and the door for ventilation and that's it.........but i still manage somehow

Ah so tomatoes are the key!     And I suppose extending a season by a little bit -

we are already eating salads from one greenhouse whilst my other one is used as a giant cold frame currently holding stock for planting out when risk of frost has gone. My polytunnel is half up and is intended for extending season particularly for bulk stuff later in season such as peas, sweetcorn etc.
I dont heat my greenhouses but I do have heated propogator about 2 metres by 1 metre which brings all my seeds along in very light conditions and which I could not easily do in a shed. Also good place to work (lurk) when weather not too good and still feel as if I am gardening. Etc. So every point from my side I think.

So regarding putting the seeds into a greenhouse to grow, since I am one of the people that do this 

Is it only tomatoes that are best grown in a greenhouse - along with the peppers etc (I am doing radishes, sweetcorn, tomatoes, lettuce, broccoli etc) mixture in the house and in the greenhouse??

early potatoes, all kinds of salad greens, rocket, greek cress, water cress, herbs, bedding plants, amusing the granddaughter, keeping carrots away from the dreaded carrot fly, starting off leeks and runner and dwarf beans and sweet corn, celery, celeriac, plus the usual toms, cues, courgettes, marrows, squashes and pumpkins, sweet peppers, chillis, aubergenes, - the potential list is endless it is just space that needs careful planning and juggling so have space for those plants that stay in teh greenhouse whilst having things ready to go out once frost risk passed.

goes off to put the sweetcorn in the greenhouse to make a bit of window sill space  ---------->>

blackcat - my sweet corn are currently in a propogator at 16degrees C in a cold greenhouse. Planted two weeks ago but by tomorrow they will be stood on the benches as they are now about 3 inches high so nened toughening up gradually for planting out in about 4 weeks time. Not sure they would have germinated without the bottom heat. No doubt you spotted that but I did not want to mislead anyone. I need their space for herbs incl some lemon grass seeds i have just spotted in a garden centre when I went in for something else !! As you do.
