Indoor growing

Hi There, what are you guys in the cold zones planning to grow indoors this year? I'm here in North Germany and since the temps dropped to 14° C two days ago fall is definetifly there. It won't get warmer anymore so growing season is over...We had a frustrating year - too dry first, then too cold then too wet, no good year for agriculture. That's why i want to grow something inside in winter - aside from making my chiles indoor plant, that is. I've never done this before so any tips and experience are welcome, also for chili care. i'm also planning to sow Thai basil and chives and maybe try physalis edulis.

I'm looking forward to hear how you're planning to extend the growing season, Sanni
