Greenhouse Report - Jeffrey 7C

Reports- December 8th
Farmer's Report- We realized that some of the plants were not growing fast enough. We assume that this is happening because the temperature is getting lower and lower. The lower the temperature the slower growing plants. We also found out that there was a problem in the raft system and the water level was so low in the fish tank. There were barely any water left in the tank. Because of this, the fishes were cold. Sadly, one fish died and we felt so sad for it.







Engineer's Report- Today there were a lot of problems. There were three leaks in the vertical system and the Engineer had to fix this problem. This time we tried a different method. We tried using the gun that shoots silicon. It was pretty useful, because it covered up the leak totally. Even if we covered up the leak, there was a little tiny leak and we didn't know how to fix. Another problem was that in the raft system, the fish tank barley had any water in it. We actually don't know how it happened and it is a mystery. We fixed this problem just by filling up the tank with water, but it took us a while. We are still figuring out why this incident happened.



Research Biologist's Report- Today I realized that the plants were not growing so fast because it is getting colder outside. If the temperature goes down, the plants won't grow fast then it is in the summer. One reason is because the days are short in winters which reduces the amount of sunlight the plants get. Scientists say that a drop in temperature slows down a plant's metabolism largely because the enzymes that drive these biochemical reactions don't work so well in the cold. This is the reason why plants grow slower in winter than summer.
