thank you for reply thinking i have got them in the greenhouse with tomatoes so i suppose i`m lucky to get any and they always get spider mite in the end

I have to do that when I grow them, some folk divide the gh into sections as toms & cues like different conditions, these last couple of years have not been easy even for toms so I haven' t even attempted cues.......good luck.....

Previous question
I find they are tricky, not liking draughts, needing moist air and prone to mildew and red spider mite to name but a few........
