Shame about your other auto that was outdoors. Nothing ventured nothing gained. At least if you do go outside again then you know what to expect although there is still a lot to learn and take nothing for granted. My two big problems were slugs and deer. Didnt take precautions for the slugs and didnt have time to erect a wee cover for protection from the deer. Almost lost 1 plant to slugs and did lose 1 to deer (i think). Next time i will make a cover with bamboo canes and netting, should provide enough cover.
Shame you couldnt set up a pump on a timer to water that bagseed while you were away. Would be very surprised if it was properly finished by the time you chop but these plants are full of surprises and it may be close to being properly finished. Where in the uk are you based?
