  • Final Blog Post

    Posted by Tetiana Koval, Jake Feldpausch on 1/17/2020 10:00:00 PM

       Throughout our whole semester of Earth Science class we were working on our system together. Basically we both were checking our system and plants all the time and we were also solving any problems that our system was facing together. Other than that I was responsible for typing and posting all of our blog posts and Jake was responsible for putting nutrients into the system. 




            Over time, as a team we learned many things about Hydroponics as a system, as we have done many searching and were working on our blog posts where we discussed our hydroponic system. Firstly, hydroponics is a subset of hydroculture, which is a method of growing plants without soil by instead using mineral nutrient solutions in water solvent. Hydroponics does not use soil, instead the root system is supported using an inert medium such as perlite, rockwool, clay pellets, peat moss, or vermiculite. Secondly, we found out that hydroponics system has many advantages, for example:

    • Hydroponics uses 90% less water
    • We can grow plants all year round
    • Plants go faster as everything plant needs is delivered right to it
    • The environment is stirile, which means no pesticides
    • The system water can be reused, allowing to conserve water
    • No soil is required

    Working with hydroponics system affected us in a good way, as we got skills in agriculture and caring about plants and work in the greenhouse. These skills will help us in our future.

           The other thing that we learned is how our system interacts with biogeochemical cycles. Also, one time we faced with the problem of fading leaves of our tomato plants and small brown spots on them. We had multiple ideas of what might have caused it, and some of the reasons include bacteria or fungal infection. After that we pulled out and destroyed diseased leaves to stop it from spreading more. We also put some more nutrients. Unfortunately we did not get desirable result, as we did not end up with any tomatoes. We believe that leave disease might have affected tomatoes growing, and also lack of sunlight. 

          The picture below represent Nitrogen and Phosphorus cycles with our system.



            Basically Nitrogen cycle plays a role in our system as our plants take nitrates through the roots, after that it is processed and used for amino acids and nucleic acids. Phosphorus plays a role in photosynthesis, respiration, energy storage and transfer in plants. Our plants needed Phosphorus to grow, and for normal production cycle.

            Our system can help areas where resources are not very plentiful to grow tomatoes in an easier and faster way because this is a hydroponics system that is placed in the greenhouse, and only requires nutrients, water, sunlight and an actual built up system itself. ALso, it can benefit our local community by growing more tomatoes and make a good profit out of it.

  • Final blog post Ejia and Kendahl

    For our system we had to mostly work together on our system to get it done. We had to make sure our plants didn’t get too crowded when they grew as well as relocating them to a larger area to allow them to grow. We had to make sure our filter was always clean so the water would run better. We couldn’t add fish to our system because we didn’t get them in time, so we added hydroponics growth food to our water to help the plants grow. 

    We have learned how working a system is not an easy task, and it takes a lot of communication skills. Anything could go wrong with it, it takes a big responsibility. It also takes lots of patience, we had to keep up with our system as much as possible. Our results would vary each time we planted something new. In the warmer weather our plants grew at a constant speed and we didn’t have to worry as much about our plants dying. During the colder months as they passed our plants seemed to have a hard time growing right and often died more having to trash our plants that didn’t survive. It was rather easy working on our system, it was easy to keep up with and set up, only difficulty we would have is the change in the weather.

    The nitrogen cycle plays in our system by the nitrites in the air coming into the system. Nitrogen fixing bacteria came into our plants to help them grow. We mostly added nutrients to our plants water to help them grow instead of mostly nitrogen. When our plants died they would get thrown away outside allowing them too after decomposing go back to nitrogen in the air. 

    Our system can help because it is small but uses up what it needs fast, meaning we have to replant a lot and allow our new plants to grow faster having more resources at a faster rate. It is easy to take care of and takes little time to manage. Our system is very beneficial to our local community getting lots done in a short time.

  • First Year Aeroponics: Final Post

    Posted by Elizabeth Leslie on 1/17/2020 9:15:00 AM

      With us ending this semester of learning I am glad to say that the production of these two Aeroponics systems has me in awe. I have worked on these systems by myself from the beginning. With this, I have created the systems, treated the water to the perfect conditions, and stuck through all of the times that I failed to have them work properly. In the past few weeks the system has grown 11 roots. 4 tomato plants, 5 succulent, and 2 petunias surprisingly. One little baby tomato that I will talk about later. This has been a great advancement in my life so please keep on reading to learn about my entire educational journey through this.


    Over the course of using my aeroponics system, I have learned more than I ever imagined. Fail after fail I have pushed through the worst imagined. 5 times replanting then trying a new plant a lot of time used to retry. So in result this system has a lot of potential. For whoever continues this journey I wish you luck. It may take time, that is okay in the end it will all work out. With your future journeys, I would like to see all of the different plants you can learn to grow in these systems.


    Now we will talk about the use of Nitrogen and phosphorus cycles in an Aeroponics system. Nitrogen flows through the system as the root hairs take in nutrients from the water and the air around them. This starts when NO2 enters the roots from either the water or the air (Mainly from the air). It continues the rest of the cycle consistently. Now for Phosphorus, Phosphorus moves through the system just like the water and some of the Nitrogen does. This happens because phosphates can not become a gas. They are only in a solid or liquid state. With this, the nutrients plants get from phosphates are only available in the water. 


    This system might be beneficial in different parts of the world that have low fertile soil. I only say this because it is very simple to use water to grow plants through this system. The system is very low maintenance due to the fact that you do not have to feed any fish or tend to soil. All that is needed is a timer set up to water plants every few hours. With this, you check root growth and the quality of the water. 


    **Small tip: succulents must be immediately transferred to the soil after root growth due to over absorbing. 


    For Sale!!: 

    As we finish the semester I would love it if someone would be willing to buy this entire system to continue the task of observation for me. All you need is a good set of eyes and some money. In addition, for the small price of 99.9 googolplexes, it will be all yours. And if you call right now you will get an extra nutrient bottle plus a thank you from our sponsors. 

    • The system, Used, great condition, Needs some love
    • Cost 99.9 googolplexestr

    At the beginning of the year we started out planting green beans and Carolina reapers. Our green beans were the only thing that grew so after about two weeks we decided to plant more beans where our papers were. We were expecting to get a crop out of our plants in the time we had but we had some environmental issues having the heat run out in the greenhouse and being gone on winter break not having enough water for the 2 and a half weeks. Our product that we could have made any money on went down the drain and we lost money. The Nitrogen and phosphorus cycle needed because a plant needs Nitrogen and Phosphors to survive.

  • Growing Flowers in The Greenhouse Final Post

    Posted by Richard Vandecasteele,Riley hinds on 1/17/2020

    We have the same tasks with the system, we water the plants, remove dead plants, stir the top layer of mulch and add nutrients to the water. Over the course of us using the system, we have learned the difficulties and we have learned trial and error. We tested amounts of nutrients in our water and we have tried to position it well enough to where it gets good amounts of sunlight. We have built a sort of vine for it to grow on. How the nitrogen cycle works is when nitrogen is absorbed by the soil, different bacteria help it to change states so it can be absorbed by our plants. How the phosphorus cycle works is, phosphorus moves in a cycle through rocks, water, soil and sediments, and organisms. Our plant grew very well through potential frostbite, a week without water and minimal sunlight. With countries with less nutrient-rich soil this could be important because it is easy to grow.
