many Germans use small glass houses/greenhouses for tomatoes -

tomatoes are sensitive to temperature swing to pollinate

Optimum fruit set occurs within a very narrow night temperature range of between 60 F and 70 F. So, when tomato plants experience night temperatures lower than 55 F or above 75 F, interference with the growth of pollen tubes prevents normal fertilization. The pollen may even become sterile, thus causing the blossoms to drop.

and humidity plans a role as well
