The above photo was taken at the end of February. The plants have grown rapidly over the past month. The window is about 185 centimeters high, so you can see how large they have grown. Since the room was heated in the daytime, these plants grew faster than those in the other room. The poles were then too short, so I suspended the tops of the plants from strings that I attached to the ceiling.

As you see in the picture above, the plant in the heated room bore small fruits. I had been concerned about the method of pollinating tomato flowers, but those fruits proved that the flowers were successfully pollinated. Those fruits were still small but I hoped they would grow larger.

The above plants are the tomatoes in the unheated room. They were not as tall as the previous ones, but obviously they had been growing day by day.

The plants in the above picture are also grown in the unheated room. This tomato plant has thicker stalks compared to the other tomato plants. There was no particular difference between this plant and the others, but this one has strong leaves and stalks.

The leaves are shiny, firm and lush. I look forward to its further growth.

At last, the plants have borne fruit. Five months have passed since I seeded. Possibly, since they grew through the winter, growth was slow. It seemed they needed more time to be ready for the harvest.

However, signs of blooming were seen gradually here and there; the plants have grown taller and taller. I noted a big difference in growth rate between the heated setting and unheated one. As was expected, growth was delayed in the colder environment. There were three different settings in the unheated room: 1) plants housed in flower pots, 2) those housed in a big planter, and 3) lots of plants densely grown in a large sieve basket. Initially, the growth rates of those plants looked the same, but when you looked more closely at the dense ones, every single seedling in the basket looked frail. Many of the dense plants had thinner stalks with leaves more lightly colored than others. However, they all grew well and none died. I hoped to harvest all settings.
