What can I grow under glass?

Anne Swithinbank's masterclass on: greenhouse crops

Q Even in the greenhouse, my tomatoes seem to get blight every year. I plan to try some blight-resistant varieties, but could you tell me what other crops I can grow under glass, just to hedge my bets?

А Tomato blight is the same fungus-like organism (Phytophthora infestans) as potato blight. Spores from infected foliage are wind-blown over long distances (literally miles), so keeping your own garden clean of infected material, although helpful, is no guarantee of avoiding the disease. All the spores need is a period of warm, humid conditions above 50°F (10°C) with surface leaf wetness to grow and infect plants. Symptoms include brown marks on leaves, stems and fruit.
