8 March Rainbow Plants March 8, 2017By Greenhouse Ambassador Aquaponics, Ecosystems 0 Aquaponics are basically ecosystems where fish and plants help each other and work together. The fish produce waste for the plants, and the plants add oxygen to the water and kept them hydrated. How tall will they grow, what is the difference in height, are some of the questions we have about plants grown in store bought soil, and in the gravel of our aquaponics system. These can have a different impact on how the plants grow. The Aquaponics systems made our plants spontaneously better and healthier. Beautiful's plant is tall and yellowish red. Janya's is pink on the end of the green leaves. Ireland's plants in the gravel tray are tall and a vibrant pink. Maddie's plants were also yellow, orange, green, and red.The chard seemed to be the tallest and prettiest plants in the gravel tray, and had really long roots. The water in the fish tanks changed color depending on what tray was above them. The water in the aquaponics system was green-ish yellow, and the fish seemed to die more easily in that one. The water in the tank beneath the soil tray was pretty clear and not a lot of the fish died. We had a lot of fun and difficulty at the same time keeping the project going: making sure we feed them on the right days, measuring them, etc. Related Posts Clay and Loam Soil vs. Loam Soil For our experiment, we had 4 rows of basil plants in two different trays. Tray 1 had soil that was made up of 50% loam and 50% clay and tray 2 had soil that was made up of 100% loam. In the tray that contained clay and loam, the plants started out growing well and we thought that was happening because the clay retained nutrients well. In tray 2, which was 100% loam, the plants also started out growing well as was expected, because loam is traditionally the best soil to use for growing plants. To our surprise, the plants in tray 1, which was the tray with half clay and half loam, grew very fast. After two weeks or so, the plants were at a height around 22 cm and were looking great! Unfortunately though, the clay eventually dried out and after a long 4 day weekend of not being watered, the plants died out. As the plants died out, the soil became really dry and looked like concrete. In the other tray that was 100% loam, the plants grew gradually and were nice and tall over the 8 week experiment. They eventually reached a height around 20 cm and proved that soil that was 100% loam is truly the safer and better call. If you are going to do any gardening, Mullanphy school suggests using loam! EcoBattle We have two trays of plants. One Gravel and one soil. In which tray do you think will do better? The aquaponics tank is not connected to the soil tray. On the other hand, the gravel tray is connected. That is very important for the plants in the gravel tray. Here is why: We have been learning about fish environments, plants, pH, nitrates, nitrites, KH, ammonia, bacteria, molecules, and macronutrients. We learned that our goldfish give off ammonia, and that is good for plants when the ammonia bacteria eats it and turns it into nitrites. Then, the nitrite eating bacteria eat the nitrites and turns into nitrates which is beneficial for the plants. The gravel and aquaponics environment produced healthy, enormous, gigantic, beautiful plants compared to the soil only environment Our main focus was on the kale in both trays. We watered, measured, and took care of them. When we first received them they were very tiny. Over time they began to grow very quickly. The gravel tray with the kale grew quicker than the soil ones. Our kale is green and it has a tint of purple. It has ruffles in the leaves and it is very similar to the mustard. It is very difficult to tell the two apart, they are both green and purple. On March 8,2017 we harvested our kale plants. We dug the kale out of its trays with forks. It was hard to dig them out , because the roots were connected. After we dug them out we measured them. We measured the roots and the plants by themselves. It was fun to watch them grow and harvest them. this has bbeen a n amazing journey. I absolutely cannot for whats next. The Marvelous Adventures of the Green Thumb Ambassadors The Green Thumb Ambassadors planted tiny seeds called basil. We planted five rows and named each row that we planted. They were called Apple,Bob,Tom,Sam, and Tristan! It was hard to space them out evenly, because they were so tiny. They were 20 times smaller than peas! We watered them daily and made sure they were moist.When they finally started growing they were white and furry. They grew rapidly and we were all astonished. On week 4 we thinned the majority of them, but transplanted some of them because we didn't want them to go to waist. For a couple of days in week five we had a gigantic and dangerous drought! We were unable to water poor and pitiful plants. They suffered greatly and were badly damaged.Tuesday we harvested the basil plants and took pictures of them. Then, we washed them. Now we plan on eating them with pizza and spaghetti and chicken. Maybe even ice cream ! We all had an amazing time in the The Marvelous Adventures Of The Green House Ambassadors! Lettuce tell you about last week Last week we learned about a couple of things. We learned that frost is mainly found in the countryside and dew is mainly found in the city. In aquaponics we learned that fish waste helps give nutrition to plants and plants help clean the fish's water. We learned that PH is a measure of acidity and it hurts fish and plants if it is out of balance. This week, we harvested lettuce. We found that the lettuce had a lot of roots, and it was hard to get the gravel out because the roots were so long and tangled. In the tray with the soil, the roots were hard to get out because there was so much soil in between. We had to use 2 rulers to measure the lettuce. The lettuce was purple and green and it had spots on it. The lettuce grew better in the tray with the gravel. We washed the lettuce then weighed it. We put the lettuce in a bag, which some of it will be taken home. Sandy-Loam VS Miracle-Grow, Basil Conquers All Basil is used for cooking and consumption. Many people grow basil at home. We decided to use basil as a guinea pig for our experiment. We had 2 trays of different soils, sandy loam and Miracle Grow. We planted basil in both of the trays and measured them as they started to grow. There were three different schools with us, and together we made four different schools working on this project. Each school had a different mixture of soil. We had sandy loam, and it isn't doing to well. There are big patches of gray and yellow and brown on the basil leaves, and the leaves are wilted, not nicely curved as regular basil is. So this is only a small portion on the soils. there are many types of soil in this expirment. the types are sandy loam, clay sand and loam, compost and clay,and clay loam and compost. Along with the maricel grow which in this case is the control. now that you ,the reader, know what the soils are nw it is time to explain how well they grew plants. Sandy loam was the best in this case. next up was compost and clay third was loam and clay and finally was sand loam and clay. On a scale of 1-10 we voted on the quality of the sandy loam soil in comparison to miracle grow: 1 being the worse and 10 being the best Sean:7.5 Carmen: 3 Maddie : 3 Jens 5.5 Callie: 10.7 The Super Basils Here are the basic ways on how to grow yummy basil. First, make sure you have enough soil and a good type of soil. Good types of soil include loam, loam mixed with sand, and normal potting soil. Secondly, make sure you don't water too much or too less, and also water the plants everyday. A good tip is to feel the soil to see if it's dry to know if you should water it. Thirdly, check the soil for bugs regularly. Fourthly, wind might not be such a bad thing. Give them some fresh air every once in a while. Fifthly, make sure they have plenty of light and put them near a window or solar light. Bonus Tip: Make sure to love them and talk to them. Comments are closed.
