Cucumbers without salmon
"It only needs some salmon!" is one of the captions of this film about women harvesting cucumbers in greenhouses. The harvest is placed inside baskets which are then taken by men to a lorry. This is what greenhouses looked like in England in 1931.
The Lemon Palace
This particular greenhouse was set up in 1936 in Russia, along the coastline of the Black Sea. The complex is a bit like a Roman amphitheatre and was used for the cultivation of lemons. That's where the name "The palace of Lemons" came from.
Tomatoes, or Love Apples
In the 1930's, tomatoes were given the nickname 'Love Apples'. In this greenhouse the harvest work is carried out by women, who make use of baskets. Afterwards the harvest is mechanically sorted.

In the 1930's, experiments were already being conducted with the substrate-free cultivation of tomatoes. Research is carried out in U.S. greenhouses. The plants are supplied with nutrients through water.
