How to Make a DIY Hydroponic System


What is hydroponics?

Hydroponics, a subset in horticulture, involves the cultivation of vegetables, fruits and herbs in a nutrients-water solution that doesn't exhaust the soil. The hydroponic system allows roots to be suspended in water or air, and plants can absorb nutrients and oxygen from the water. The growing media acts as soil, maintaining the moisture level and keeping nutrients intact. Hydroponics' preferred media is system-dependent. It consists of perlite and coco coir, gravel and clay pallets. Hydroponics offers many advantages, including the precise application and mixing of mineral nutrients in both liquid and dry formulations. Growers are able to monitor and control their growing environment and, in return, achieve the highest production milestones regardless of outdoor conditions.

Hydroponics System for Beginners: Best

Deep Water Culture (DWC).

Deepwater Culture (DWC), the most popular hydroponic technique, allows for the suspension of roots in oxygenated water with dissolved minerals nutrients. The most common hydroponic grower uses an oval tank that can store approximately 10 inches of water. Essential nutrients are provided precisely, and the plants flounder in the Styrofoam board on the surface. Hobbyists prefer to grow in homemade hydroponic systems using netted pots. These allow roots to penetrate the growing medium and hold the base of plants. Airstone encourages oxygenation, which links the airline to an electric pump. Deepwater cultures, as all protected environments, require constant regulation of temperature, humidity, pH, EC, and oxygen. Any of these factors can lead to misadventure.

What can be grown using DWC?

DWC allows for the growth of short-maturing plants such as herbs, microgreens, leafy greens, and vegetables. The most preferred crops to grow in a DIY DWC system are basil, wild rockets, Swiss chard and kale.

How to make a DIY Deep Water Culture Hydroponic System

Freshly-produced, nutritious and delicious vegetables, herbs, or microgreens are a basic household necessity. Many people spend hours going to the grocery stores and supermarkets to get such produce. The Pandemic slowed down all of this, prevented many officials from going to work, and allowed them to work remotely. Market prices rose so much that gardeners were forced to think outside the box. The first option was to grow fresh produce at home. DIY hydroponics was the most urgent choice, made with the best materials at home. Let's see how they built hydroponics at their home DIY- DWC. And those things that were not found in your home can be bought inexpensively from one of the hydroponics equipment suppliers.

Materials Required:

  • Water reservoir container
  • Pots with plastic netted lids
  • Check valve on air pump
  • Double-sided Adhesive Tape
  • Tubing for an air pump
  • Airstone
  • Nutrients Solution (A & B).
  • pH & E meter
  • Humidity Meter
  • Thermometer
  • Glass beaker
  • Micropipettes
  • Use a hole saw to drill

How to Choose a Water Reservoir Container

Choose a container that is approximately 12 inches in depth. The top 3 to 4 inches may be occupied by plastic pots. Submerged roots may have more than 10 inches of water to use nutrients. A deeper container will allow you to adjust the pH and EC faster. It is preferable to use a black container lid. If you don't have a black container lid, paint it black so that light doesn't reach the roots.

Drilling holes into container lid

We are to grow our plants using netted pots. The holes in the container lid will hold the pots tightly and prevent them from falling into the water solution. Depending on the size and needs of the plants, holes may be 4-12 inches apart. It is a difficult job to drill holes in the container lid. Be careful.

Assembling an air pump

Use adhesive tape to attach the air pump to the outer wall. Use appropriate tubing to connect the check valve to the air pump and then attach it with an airstone. Make sure the arrow points toward the airstone

Fill water reservoir and add nutrients

The reservoir should be filled with clean, filtered water. The water should be brought to room temperature. For most hydroponic plants, pH should be checked and adjusted to a level of 5.5 to 6. As per the product label, add nutrients. Many Nutrients A & B include instructions for adding between 2ml and 4ml of nutrients per liter of water. This depends on the amount of Mg, phosphorus or potassium in the solution. Hydroponic solution DIY instructions are available in most nutrient manufacturer's booklets.

Correct EC, Temperatures, Lights and Dissolved Oxygen

After you have added nutrients to the reservoir, verify that the EC is correct. DWC crops prefer ECs between 1.1 and 2.1 dS*m-1. Adjust the water temperature from 65 to 77.0 degrees F and keep the air temperature at 75.0 degrees during the day and 66.0 at night. To reach the required dissolved oxygen level, Hydrogen Peroxide must be added to the system. However, this varies depending on the crop.

Finalize the Setup and Plugin Plants

After placing the airstone into a reservoir, and plugging it in to the air pump, complete the setup. Close the lid carefully and place the plants in the netted containers. Now you're done.

Tips to Maintain Your DWC Hydroponic System

  • For successful harvesting, contact between roots and water is essential. You should monitor your water levels regularly and add nutrients solution after each addition.
  • You can be sure what the nutrient's per-liter requirements are. For certain, verify the EC after adding nutrients.
  • For successful growth, the primary factors are temperature, pH, and dissolved Oxygen. All of these factors should be checked at least once every four days. A single disturbance could prevent your plants from receiving the nutrients they need to grow.
  • Replace the reservoir water immediately after each addition.
  • Clean the salts in the base after you add water to the reservoir. These salts are often not absorbed due to higher pH variations in nutrient solutions.
