A Beginner’s Guide to Hydroponic Farming

Hydroponic farming has long been practised by many farmers throughout the world. But with the advent of new technologies and equipment. It is now more accessible than ever to those who want to reap the benefits of these water-based systems.

Whether you are just starting out. Or are looking for ways to grow more crops in your current hydroponic system.

Know about Hydroponic farming

Starting a hydroponic farm is not an easy thing to do, and if you want it to be successful. You need to understand the basics and plan your business accordingly. Otherwise, you could end up with a bad harvest and no profits. Which wouldn’t be good for anyone involved in the operation.

That’s why it’s important to do your research before making any sort of decision. About how to go about growing your crop in the long run. Especially if this will be your first time starting up such an endeavour.

Introduction to Hydroponic Setup 

The world of agriculture has changed drastically in recent years. With hydroponics becoming one of the fastest-growing farming methods. A hydroponic system consists of a nutrient reservoir and a growing medium. This supplies plants with all their needs via water.

Because water provides oxygen for plants. There is no need for them to suck up large amounts of air from the soil. Giving them more room to grow their roots and greatly increasing their growth rates.

There are many different types of Hydroponic Farming systems available. We’ll go over some basics here so you can decide which type of setup works best for your area and crop choice. Before reading on, though, it’s important to understand how plants get their nutrients. They pull them straight out of the ground or container you put them in. This means they rely on three things: sunlight, water, and nutrients.

What is hydroponics?

But what is hydroponics, exactly? It’s a type of growth that allows you to grow plants without soil. The roots are exposed directly. Roots are inert in the medium like gravel or clay pellets, instead of dirt. This method offers several benefits over traditional soil gardening. And includes healthier plant growth and increased yield.

Hydroponic setup

At its most basic level, hydroponics setup is about growing plants in water. Many people equate hydroponics with aeroponics (growing plants suspended in air). Also on aquaponics (in which fish tanks supply nutrients for your vegetable crops). But those aren’t necessarily true. There are several different types of hydroponic systems out there.

We’ll discuss some of them here as well as their pros and cons. If you want to start a little herb garden indoors under artificial lights, top-fed DWC is probably all you need to know. If you have a green thumb and want to do something bigger. Then it’s time to head down to our section on NFT or deep water culture.

Benefits of hydroponics

Growing plants without soil is a great way to enjoy your hobby of gardening while reducing your workload. With hydroponics, you’ll be able to grow all kinds of different plants, including herbs and vegetables—all year round!

Here are some more benefits of using a Hydroponic Farming system for your home or business.

  • You don’t need much space:

    a hydroponic system can be set up anywhere—in an apartment, on top of an office building, in your back yard or even indoors (where legal). Since you don’t need soil, you can grow crops inside if weather permits. And depending on how elaborate your setup is. You might only need one plant-growing chamber. Instead of multiple rooms filled with growing beds. The other traditional growing techniques like indoor organic gardening. This makes it easier to set up a garden in places where there isn’t enough room for a normal crop.

  • Low maintenance required:

    If you decide to start an indoor hydroponic garden, there aren’t many daily chores involved. While you might need to water your plants every day, that doesn’t take too long. If you have a drip irrigation kit installed, then watering takes less than 10 minutes per day. Since these systems only work when they come into contact with water. Other than that, all you have to do is check on your plants regularly. Also, remember to keep an eye out for signs of insect problems. Such as spider mites or caterpillars damaging leaves.

How to Choose your hydroponic system

Once you’ve decided on a method of hydroponics, your next step is setting up a hydroponics system. This requires a little math and a lot of planning, but once you have it down, all that’s left is filling your pots with soil or planting medium and planting your seeds.

You’ll need to know how much space you have in your home for growing plants and how many plants will fit in each pot. Are you interested in starting an indoor operation (indoors anywhere from 60 to 90 degrees). Or an outdoor garden (indoors anywhere from 40 to 90 degrees)?

Are you interested in growing herbs, vegetables, fruits and/or exotic plants? Are there any other factors you want to include? These questions should help frame what kind of system will work best for your needs.

Things you will need for Hydroponic farming

Planning out your hydroponic farming business can be a little more involved. When compared to simply purchasing some equipment and getting started. Here’s a step-by-step look at how to get your own hydroponics farm up and running.
