I have tomatoes in a greenhouse and also some planted outside. All
planted/potted on at the same time.
Those outside have very thick stems - as thick as a little finger -
those in the greenhouse much thinner and much taller. All have
reasonable quantity of flowers on.

Too late for this year - but is it worth "slowing down" those in the
greenhouse in the future - or does it not matter - if so how?

I guess I can make effort to weigh all fruits off one of each and
compare - but I'd still be interested in views/comments.

As a general rule it is advisable to 'stop' (pinch out the leader) of
greenhouse tomatoes when the sixth truss has formed. Best to 'stop'
outdoor tomatoes at 4th truss. This will encourage the fruits to set,
develop and ripen. If you do not 'stop' them you will have lots of
tomatoes which will not ripen successfully.

Also ensure that there is good air circulation in the greenhouse by
progressively removing spent leaves from the base of the plant upwards.
If you prise a spent branch upwards it will break off cleanly from the
main stem and hopefully not leave a site for mildew to develop. A puff
of green sulphur will help to prevent the latter. The greenhouse door,
windows and vents need to be open in the daytime and closed at night to
trap the heat.
