This report expounds upon my ideation of Pink Prospects, a small-scale hydroponic drip system that I may develop within a community space, Pink Houses Community Farm. Pink Prospects is intended to improve public awareness of hydroponics while also offering useful, culturally-desired crops that mightn’t be readily available. To start, it will raise some species of amaranth/callaloo.

Though Pink Prospects will be the focus of this document, it will also briefly present some of my other small-scale food system solutions that could incentivize composting, improve awareness of local food resources, and widen the variety of crops in the neighborhood.

My neighborhood—East New York, Brooklyn, has been reported as one of the poorest in the area, and is also a food desert with a high density of fast food chains. Yet paradoxically, there are several well-kept growing spaces within ten blocks of me, and a good number of weekly food distributions.

Origin

My project took form as the teachings of Change Food for Good’s Intro to AgTech course and my own observations admixed. I’ve regularly volunteered at several food pantries weekly over recent years, and love visiting Grow NYC’s Cypress Hills farmstand as well. Access to food resources has improved here, but still seems disjointed. There are many great public farms and families with prolific, passionately-kept gardens. Yet many people who need these services seem unaware of their existence.

Additionally, some local composting services in our neighborhood have been defunded and terminated because of low or improper use. I shared compost with the Cypress Hills GROWNYC Farmstand for most of the past two years, and formed great friendships with its attendants. Yet there were increasingly many weeks when I was the only person to drop off scraps, even though the service was available all year.
Our course tasked us with trying to find a hydroponic solution to a food system issue. Some of the various public growing spaces in the neighborhood may be able to foray into hydroponics to help draw interest to both their activities and the practice itself. That could ultimately strengthen the community, food education, and give these organizations and services opportunities to cross promote.

Considered Factors

A local, outdoor hydroponics system should be tuned to at least the following points:

My Recommendations and Rationale

I planned this system at its initial small scale in respect to my inexperience and its power source. That extends to its seasonality. This is equal parts a test of myself, the plants + hydroponics, and public interest.
To increase the worth of the project, I'd want it to inform the community, not just through exposure to hydroponics, but perhaps a map that details where and when the various food pantries in our neighborhood distribute. With experience, it may be possible to accelerate yield not only by expanding the system to grow more plants, but by growing from cuttings! If successful, this bypasses the wait for fresh seeds to germinate. Additionally or alternaitvely, I may be able to focus some of the off season on seed storage or starting instead.
Our class site visits were all highly informative, but so was consulting locals. My gardening neighbors, the Dixons, raise many plants, including some types of amaranth. They taught me of its health benefits, repeat harvesting, and how easily it can spread. It may be best to start by raising nonflowering amaranth species.

After all, Mrs. Dixon warned that most of the amaranth growing in her garden wasn't planted. It had been sown by wind or animals flying by. That's impressive, but must be monitored carefully in a public growing space.

There are several components to the problems I want to address. Articles and findings like these indeed support that East New York is a food desert. With low spending power, healthier organizations may simply be dissuaded from establishing presence here.
There also seems to be a general lack of public info on the composting process, assuring that only homes with avid gardeners may easily learn of it. That lack of attention and misuse of the service easily gets it demonetized, as I've personally witnessed. It's especially disappointing since we have so many nice local farms.

As stated earlier, some of the public may be unaware of the free food distributions available to serve them. While they're readily available, they may not be well-advertised. People who work in mornings or afternoons may never chance upon them, or even have the opportunity to benefit from them if they do.

The Project Plan, a summary of the tasks required for this proposal

Over our trips and my own outings, I've seen some variance in the height of amaranth plants. Though some are clearly of different species or possibly at a different stage of life, I wonder if and how growing method and medium influences that.

There are a host of reasons why well-raised plants of the same species may have distinct heights when mature. Some could be dwarf varieties bred for shortness, which could be more appealing in stacked indoor systems. If I raise any amaranth, I'll be sure to compare them. It could clue me into which types of seeds are best to order. To oversimplify, shorter plants would usually need less support, possibly less clearance between them, and perhaps not scatter their seeds as broadly if pollinated by wind. Some may simply be better neighbors if grown with other plants.

  1. Having to defer many solutions that I couldn't incorporate hydroponics into, like seedkeeping, a traveling community seed bank, and a composting incentive program
  2. Likewise for several great suggestions and desires of my supporters. One of the Dixons suggested a program that teaches about the various "wild greens" in our neighborhood and their uses. Wild greens are plants which are commonly regarded as weeds, yet can be useful as food or medicine, and are readily available since they're hardy and grow easily.
  3. The realization that dates and starfruit either aren’t very compatible with beginner hydroponics, take too long to yield, etc.
  4. Having learned that Pink Houses Community Farm has no electrical power, I felt forced to use a system that doesn’t need power, which wouldn’t have been in the spirit of this course or project.
  5. The risk of this system being vandalized, stolen, or elsewise fiddled with, since it will be outdoors and exposed to nature and the public.
  6. Difficulty and indecision finalizing my farm system design, which has also manifested in other elements of my course work since it’s so crucial.

  1. The lack of electrical power at Pink Houses Community Farm eventually lead me to learn of alternatives! There are relatively inexpensive drip irrigation pumps that should be great for a small system like this. Later, I was also told of another alternative hydroponic irrigation system that doesn’t need electrical power at all! I'd like to test it once I've taken more time to study it. There even exist sun direction websites to help me plan how to orient a solar panel.
  2. My first choice(s) of crop wasn’t suitable for hydroponics of my inexperience, but I learned that callaloo is perhaps an ideal starter crop. To list a few benefits, it is apparently easy to grow hydroponically, drought tolerant, and accepts a wide range of growing zones. It's also high in iron, fiber, and vitamins A and C. There are many species of amaranth/callaloo, some of which flower, and in many cases, virtually all parts of the healthy plant case be used. I've even read that the grains can be good feed for farm animals.
    Better yet, surprisingly few people curious about my project dislike callaloo. I've yet to try it myself, though. But I can't ignore that some individuals would only be interested in select species of amaranth.
    The aforementioned librarian, Sydul, would only want red amaranth.
  3. If I realize this project, am competent in its maintenance, and ever want to extend its growing season, community farm staff have suggested I request to use a spare room in nearby community center. Furthermore, it may be possible to grow within the hoophouse at the community farm, or pivot to cold-tolerant crops like cabbages when amaranth is out of season. However, that would require a more complete understanding of the plant family's artificial lighting needs, and additional supplies.

To begin, here is a map view of several public growing spaces I considered. There were around three other locations I pondered, but I won't include them all for brevity.
I'm pleased and impressed that our neighborhood has so much growing space.

I ultimately settled for Pink Houses Community Farm. It's the closest of all, and thus swiftest to reach for maintenance. It has passionate staff and several volunteers and visitors, so I know my system would be seen. There are also many tools and conveniences available, including a hoophouse. That's great for plants that love warmth and humidity. I visited the farm for several consecutive days to measure the area and note its conditions and features. With tape measure and sketchbook in tow, I took some loose measurements and produced sketches. That way, if I were ever to model some part of the farm, I could at least give it realistic dimensions. Where I couldn't measure curves, I used gate segment spans to help my estimates.

The numbered spots are the four locations in the community farm that seem best for my system.
  1. wouldn't obstruct any other plants, but receives the least direct light.
  2. is close to a water line and tools, but perhaps often shaded.
  3. is near a water line and well lit. But the plants may deny light to shorter ones if they grow particularly tall.
  4. is a hoophouse (if not a greenhouse.) It gets excellent lighting, but doesn't have direct water service, and is frequented by stray cats.

Only recently did my brainstorming and sketching finally lead me to a system design that seems adequate. But now I must finally model it in Sketchup or Fusion 360. After that, I'd like to build a mock-up of it.

I want to grow no more than 3 or 4 plants simultaneously to begin. None of my research gives much mention to amaranth being grown in a drip system, so I might opt to have some grown traditionally or in a simpler, separate hydroponics system for comparison. I'd like for the plants to be 10-12" apart, but still relatively close so that the pump needn't work so hard. The strength of the pump also places a limit on how high the plants can be elevated compared to their reservoir (water/nutrient source.) Elsewise, there's a risk of blockage or backflow.

Amaranth greatly favors sunlight and doesn't need much water when established, so I think a drip system (which dispenses liquid precisely and conservatively) could excel.

The three files above were among my early note pages and failed designs. But it was important to ponder and explore them, especially the differences between different types of hydroponic systems. When I thought I'd have to settle for one of the simplest types of systems, I considered ease of transport as a feature.

This will be the basis of the design I model. A north arrow is present since the orientation of the solar panel will be crucial.
2d and 3d design
After extensive ungainly practice, I managed to bring the visual model of my design to this state. It will be improved as I do in Sketchup or other modeling programs. This system can be arranged in other ways, and doesn't occupy much ground space since the electrical components are all so simple. Since this is a drip system, I may put all of the plant pots in foil containers that could catch any excess liquid from the reservoir.

My dimensions and annotations are hidden in the images below since they make the file hard to read. I now realize that viewers aren't allowed to adjust/remove layers, see hidden objects, or place my components for close viewing. But I'll still include links to the model for now. If you view them, you can zoom or orbit to change which notes are visible and how they're positioned.

The item dimensions generally follow what you'll find on my materials list, but some specifics (like the pump console) had to be estimated from videos.

My Assorted Gratitudes
One inviting neighbor family Teachers and fellow students of Change Food For Good One regular at the community farm
Here are a few of the many individuals and groups who made it possible for me to complete this project. In no order of contribution, I'd like to thank:
  • The Dixon family, with their inviting nature and immense gardening experience.
  • All of my classmates, teachers, and partners in Change Food For Good, with their wealth of specialties and perspectives.
  • The staff and guests of Pink Houses Community Farm, who demonstrated to me how well-minded and beloved the space and its services are.
  • Local library staff, for their continued curiosity, interest, and critique.
  • Simply existing in a reality that allows these flora and processes to exist.
Ways I'd Improve My Procedure

Those with a similar task, know the following...

- You need solid procedures and failure contingencies in mind throughout the process, especially once your system is live. If you’re an absolute neophyte to working with hydroponics as I am, I’d suggest you either begin with a simple crop or a simple system design, then build to more demanding ones once you’re competent.

- Openly question available experts and instructors, yet also gain comfort doing your own research. E-mails and phone calls to local organizations can also be fruitful. If you’re actually going to build and tend the system yourself, be warned—it’ll constantly demand some of your time. Problems ignored and left to fester could kill your plants.

- Trace your understanding, especially if you're new to a concept! That is, assure that you know how you executed the parts of your project. That's one of the surest facets of learning, and may even grant you the capacity to better reproduce your experience.

- This project isn't over just because you submitted it, even after the presentation, and even if you don't intend to build it. You can still apply refinements.


My valuable insights from this course

My learnings from this course are vast, many, and likely to develop as I do. This project genuinely left me impressed with my neighborhood, from the Dixons' decades of horticultural passion and knowledge, to the wealth of urban farmspace that virtually surrounds me. I initially had no intention of making my project real, but as I learned how much the community supported and would want it, I became driven to do more with it. I'm pleasantly surprised that callaloo seems to be such a beloved and potent food, too.
The community wants to improve its resources.

It'd be rude to think my peers and teachers anything less than astounding. Several of them have existing agricultural experience, and even those that didn't have some fascination with agricultural technology or concern for the food system. I wouldn't be surprised to see several of them become formidable activists in the future. I think we all did a great job of girding and charging one another.

All the science and procedure of soil-less farming drew a huge smile from me. I never expected an opportunity to see these rigors and considerations so intimately.
The bevy of ways that one can specialize or contribute to these fields is just as fascinating. Again, Thank you, natural world, Change Food for Good, and all else that made this course possible.

During this project, each student had to connect a plant-identifying API (application programming interface) to identify plants and their condition. It's a useful feature for anyone interested in plants or raising them. We applied some coding to integrate it.
