Build A DWC Hydroponic Garden in Less than an Hour — August 9, 2019

Build A DWC Hydroponic Garden in Less than an Hour

Ever have the urge to grow something green? Since most of us live in cities, access to space to grow plants is practically non-existent, and soils are often contaminated with heavy metals and other industrial pollutants. Despite these conditions, people are using creative hydroponic growing techniques that do not rely on traditional methods of growing food.

Hydroponic systems are unique in that they do not use soil to grow plants, but rather delivers nutrients to plants using nutrient-rich water, also called nutrient solution.

Recently, I created a container deep water culture hydroponic system by re-purposing an old plastic storage tote. In deep water culture (DWC) systems, plants sit directly in nutrient-rich water, and an air pump & air stone keeps the water from getting stagnant by blowing bubbles into the water.

It was super easy, and I’ve outlined the steps here so you can construct your own DWC hydroponic herb garden for your home today!

Step 1: Gather your materials (see links at end of post):

-Storage tote,
-Drill,
-2″-3″ hole saw drill attachment,
-Net pots (2″, 3″),
-Coco coir plugs,
-Dry nutrients part A and B for lettuce (also good for herbs),
-Digital EC meter & pH meter,
-Measuring spoons,
-Air pump,
-Air stone,
-Herb & lettuce seeds

Step 2: Drill holes into the lid of your storage tote.

You can drill as many holes as you think will fit the size of your tote’s lid. I went with 13 holes after spacing out each plant site about 3″ apart from one another. When complete, remove all plastic scraps and debris by rinsing the tote out.

Step 3: Fill the container nearly to the top with tap water & add dry nutrients.

A simple method for making nutrient solution is to to take a quart-sized container (like an old Chinese food container) and fill it nearly to the top with tap water (you can use the water that is already in your tote.) Then, add a teaspoon of part A and a teaspoon of part B of the dry nutrients. Add nutrient solution to your reservoir where your plants live, and measure the electrical conductivity (EC). You want the EC to measure 900-1300 ppm to grow most herbs and lettuce, and you can add another teaspoon of each part A & B as necessary to reach the desired EC level. After each harvest, check your EC and add nutrients & water when necessary to maintain 900-1300 ppm range.

Step 4: Installing the air pump and air stone

The air pump attaches to the air stone via a small plastic tube (usually provided). Place the air stone in the nutrient solution and the air pump at a higher elevation than the level of the water in your deep water culture system (to prevent a siphoning of water out of your system).

Step 5: Insert the net pots into the holes you cut for each plant site.

You want the bottom of the net pots to be submerged in nutrient solution, so push the net pots in and then add a coco coir plug to each plant site.

Step 6: Plant your herb and lettuce seeds & place under light source.
Now you are ready to plant your seeds in each plug (1-2 herb/lettuce seeds per plant site).

*Be sure to place your system under sunlight or an artificial light source to ensure your plants can photosynthesize!

Recommendations:
-If it’s summer, consider placing your DWC hydroponic garden outside under the direct sunlight, or if one of your windows gets a ton of sun, place it there.

-If you have space under a coffee table, consider installing these lights on the bottom of the table and placing your DWC hydroponic garden under there: https://www.amazon.com/Integrated-Fixture-Extendable-Greenhouse-Installation/dp/B07FZTKYXV

-If none of your windows get enough sunlight, you can purchase an LED lamp to provide your plants with the lights it needs.

Empowering Youth to Grow Food: Teens for Food Justice — April 15, 2018

Empowering Youth to Grow Food: Teens for Food Justice

I’m humbled to be volunteering as a mentor to teens at Clinton DeWitt High School in the Bronx with a non-profit organization called Teens for Food Justice (TFFJ). The mission of TFFJ is to create a realistic solution to food insecurity, or lack of access to healthy and nutritious food, by empowering youth to build and maintain sustainable food systems in their community.

TFFJ leads a team to train students in Title I schools in the unique craft of urban farming through the “building and maintaining of indoor farms that yield more than 22, 000 lbs. of fresh produce annually at each location” in Brooklyn, Manhattan, and the Bronx (http://www.teensforfoodjustice.org/).

Additionally, these youth-run urban farms are feeding students nutritious and fresh meals in their cafeteria, as well as increasing the food security of the area by distributing fresh produce people in the surrounding local community. There is also a focus on teaching students about advocating for policy on the local, state, and federal levels of government to ensure that funding and other resources are given to increase people’s access to healthy food options.

Moreover, the mentorship program I am participating in has been really rewarding. I help facilitate a wide range of activities aimed at teaching the students about creating and sustaining hydroponic systems, advocating for food justice in the policy setting, cooking healthy and nutritious meals.

Finally, the students put on a Leadership Conference at Agritecture Consulting where students presented data they collected from surveys they designed and conducted in the community around their school to see what fresh, healthy food was available to stores and restaurants.
