courgettes and tomatoes

[purdy2007]

I have been told I cannot grow cucumbers and tomatoes in the same greenhouse does the same rule apply to courgettes and tomatoes?

I've grown cucumbers with tomatoes in the same greenhouse,, seems a waste to grow courgettes inside though, they crop really well in pots in a sunny spot outside I wouldn't put them in the same growbag or soil though
