While in Israel we visited a community that had once been a Kibbutz. We went through several green houses and it was fascinating. As we moved from one room to another. There were thousands of flowers at all stages of growth. Different rooms also had different temperatures. That meant we had to move quickly between rooms. I learned that orchids grow best in clear pots.
They had plants on trays that rolled and hanging above they often had plants. When they wanted the room to be dark they had like dark curtains tha unfolded. I did not see the computer room that helps control all this but we told there was one.
I took several pictures and saw some plants I had never seen before.
