Greenhouse Report - Jeffrey 7C
Andrew Kim's Documentary - Promoting the greenhouse Project
Greenhouse Report - Jeffrey 7C
Reports- December 10th
Farmer's Report- Today there was a problem in the vertical system, so we had to fix it, but we didn't have enough tubes. That is why we decided to use the tubes that we already used. We realized that in those tubes there were too much green algae. Algae are just like other plants. They need water, sunlight and nutrients for it to grow. Algae are growing inside those tubes because they receive water, receive sunlight and receive nutrients that goes through the tube. I will talk more about algae in the Research Biologist's Report.
Engineer's Report- There was a problem in the vertical system. The water pump was running too fast making the pipes filled up with water. The pipes were filled up with water and that made the bottles overflow too. Then the 4 rows of the system was destroyed. For now, we stopped the whole system and we are fixing the system and trying to find out what made this happen, so this problem wouldn't happen again. As I mentioned in the Farmer's Report, algae was stuck in the tube. We fixed this problem by putting a small piece of tissue inside the tube and pushing the tissue with a wire. If you push it all the way through, the tube would be perfectly clean. With those tubes, we fixed the vertical system. We tried to try out the product that Ismail made for the Vertical System.
Research Biologist's Report- Algae is a simple nonflowering plant that contains chlorophyll but no true stems, roots, leaves, and vascular tissues. Algae can grow anywhere. Algae only needs sunlight, water, carbon dioxide and a few inorganic nutrients to grow. It was possible for algae to grow in the tubes where because it received sunlight in the greenhouse, had water because water flowed through the tubes and in the water we put nutrients. We can stop this from happening by covering the tubes with duck tape or foil to stop sunlight from coming through the tubes. If we do this, algae wouldn't grow in the tubes because they need to sunlight to survive.

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.

Greenhouse Report - Jeffrey 7C
Reports- December 5th

Farmer's Report- As I mentioned in my previous blog, some plants were growing slower than the other plants. After we tried out the rectangular foils on some of the plants, it actually worked. That is why we decided to put these on multiple plants that were not growing fast enough and need more sunlight. Today, the farmer accidentally put too much fish food in the tank for the fish. Unluckily, it was a problem. The fishes didn't eat all of the fish food so the fish food was ripped apart and it landed on the bottom of the tank. This would make the tank dirty. Another problem was the the fishes were so full. If this happens, some fishes might die, which we don't want.

Engineer's Report- On the previous post, I said that there was a leak and we fixed it by putting hot glue gun on it. It did work for a short amount of time but it started to leak again after a short amount of time. The Engineer put even more glue gun on the leak and the leak stopped. Even if the leak stopped, it is really fragile and one touch can make the leak start again so we have to be really careful.
Research Biologist's Report- Today the Research Biologist decided to check which plants were growing the best in which system. The pumpkins were dominating the Grow Bed System. In the Horizontal System, there were multiple plants that were growing pretty well. The super sioux tomatoes, beans, snow peas, and pumpkins were growing really good in the Horizontal System. In the Vertical system, there aren't any plants that are growing really well. We realized that the pumpkins were growing really well in the Grow Bed System because the pumpkin plant's roots are enormous. They need a lot of room to fit their roots in and the Grow Bed System had a lot of room for the roots. I feel that there aren't dominating plants in the Vertical System because the vertical System doesn't have enough room and it doesn't have the space to make plants sprout their roots. I also think that there were many leaks and other problems in the Vertical System that affected the plants.

Greenhouse Report- Jeffrey 7C
Reports- December 3rd


Farmer's Report-
The farmer realized that the plants didn't receive enough sunlight. If a plant doesn't get the enough sunlight, they end up getting smaller than we expected them to be. The problem was that the tall plants that has wide leaves were covering the sunlight that the smaller plants needed. As a result, the engineers found out a way to fix this problem.
Engineer's Report- As we stated it in the farmer's report, some plants were not getting enough sunlight from, so we decided to use foil wrappers. We made 2 rectangles out of foil wrappers that are about 15 cm tall. Then, you put it on both sides of the plant. When the sunlight hits the tall foil, it would make a reflection towards the plant. With this, the plant can obtain more sunlight from before. There was another problem in the Vertical System. On the bottom of the bottle there was another leak. We realized that the hole on the cap was too large for the tube to cover, so there were drips of water coming out. First, we tried putting scotch tape around the tube and make the hole block up.

Unfortunately, it didn't work out so well. This time we tried the electric tape and it still didn't work. We finally found out the solution by using glue-gun and covering the hole.

Research Biologist's Report- As we mentioned in the farmer's report, some plants didn't receive enough sunlight. The less the sunlight, the shorter the plant would be. Photosynthesis when the plant makes food from the sunlight, but if they don't get sunlight, it's same as not giving the plant it's food. If we leave the small plants alone, they are going to eventually die and we don't want that to happen. That is why we decided to make those rectangular foil to make the plants get enough sunlight and grow healthy.

Greenhouse Report - Jeffrey 7C
Reports- December 1st
Engineer's Report: Today in the Vertical System there was a leak under the cap of the bottle. At first we knew that there was a leak in the Vertical System, because water was dripping, but we didn't know were the actual leak was. We started to find leaks. As we looked for it, we realized that it was coming out from the under of the bottle. We realized that between the tube and cap, there was a small gap. As a result we fixed it by just simply covering the tiny gap.
Research Biologist's Report: Because some plants were not growing the ways we want, we decided to research about why this is actually happening. Some of our plants had brown tips. This was happening because of dryness, not getting enough water, or if the humidity of the temperature is too low. Some plants were facing down and they look like they are withered. This is because they didn't have enough water or if they receive too much water.
Farmer's Report: The farmer realized that there were some plants that were growing the way we didn't want it to. On some of the plants, they had leaves with brown tips. Some plants were facing downwards and they didn't seem to look healthy. Thankfully, most of the plants are healthy
