Basic Hydroponics: Getting Started

Hydroponic lettuce

Hydroponic farming has revolutionized the way we grow plants, and lettuce is no exception. Lettuce is one of the easiest vegetables to grow hydroponically, making it a great starting point for beginners. Because of this, we'll use lettuce in our examples on how to get you started with the basics of a plant's hydroponic system.

Choosing the right system

The first step in growing lettuce hydroponically is choosing the right system. There are several hydroponic systems available, including deep water culture, nutrient film technique, and drip irrigation. For growing lettuce, the most popular hydroponic system is the nutrient film technique. It's simple to set up and maintain, making it a great choice for beginners. With recent developments, you can even automate these systems to assist you with ease of worry. As long as it's on, it can keep growing.

Choosing the right lettuce variety

The next step is choosing the right lettuce variety. When growing lettuce hydroponically, it is essential to choose a variety that is well-suited for hydroponic growing conditions. The most popular varieties for hydroponic lettuce are butterhead, loose leaf, and romaine,

Preparing the growing medium

In hydroponic farming, the growing medium replaces soil as the growing medium. For growing lettuce, the most commonly used growing medium is rockwool. It is lightweight and provides excellent water retention. Before planting, soak the rockwool cubes in water for a few hours to ensure they are fully saturated. This will help your germination success rate, or the probability of the seedling sprouting healthily.

Planting your seeds

Once the growing medium is prepared, it's time to plant the seed. Place the seedlings in the pre-drilled holes of the rockwool cubes, you do not need to use these as there are many growing mediums to chose from. However, these are affordable and readily available in most big box stores. These are also designed to help germinate and ensure that the roots are completely covered during this planting stage. Then, place the rockwool cubes in the appropriate holders.

Maintaining the system

Hydroponic systems require regular maintenance to ensure optimal growth. This includes monitoring the pH and nutrient levels in the water, as well as checking the water level and temperature. For the example of growing lettuce, it requires a pH range of 5.5-6.5, and the nutrient levels should be adjusted based on the growth stage of the plant. Many plants also use this range of pH for optimal nutrient absorption. If you have questions, contact FRield and we will be happy to discuss more information.

Harvesting your Yield

Plants are ready to harvest when the leaves or fruits are large enough to be picked. For lettuce, harvest the outer leaves first, leaving the inner leaves to continue growing. What is nice about lettuce is that can be harvested continuously, providing a constant supply of fresh, healthy greens. There are many plants that harbor this technique.

One must note that other plants may require post-processing such as curing til dry or reserving in jars for storage.

Growing hydroponically is a simple and effective way to produce fresh, healthy greens. With the right system, plant variety, growing medium, and maintenance, you can enjoy a bountiful harvest of any kind all year round.
