If you want to start a hydroponic system at home, you have many options. You can purchase pre-made kits or you can do it yourself with a few basic tools. There are a few tips to follow to ensure you get the most out of your new system.

Substrates for hydroponics

If you are looking to start a diy hydroponic system, you will need to choose the substrates that you want to use. These are the materials that hold the water, nutrients, and air in your hydroponic system.

The best substrates are porous, which helps to retain air and water. You can find a variety of different substrates that can be used in your hydroponic system. Substrates that are a good choice include rockwool, sand, expanded clay, and peat moss.

Rockwool is a common substrate that is made from limestone or granite. It can be spun into super thin fibers that provide a solid structure that holds water and provides oxygen to plants. This substrate is ideal for hydroponic growing, and has been used on commercial farms for years.

Sand is a cheap and easy to find substrate. It has a poor water-holding capacity, however, so it may need to be mixed with other media for a better water-holding capacity.

Packing peanuts are another inexpensive substrate that will retain water well. However, they can cause contamination if they are not cleaned properly. They are often used in Nutrient Film Technique systems.

Expanded clay is also a popular substrate for hydroponics. These pellets range in size from 1 to 18mm. They are often called grow rocks.

Pumice has similar properties to perlite, but is a lighter stone. It is also a very porous medium, allowing for a great root environment.

Coconut fiber is becoming a popular growing medium. Unlike other substrates, coconut fiber has no plastic components. It is 100% organic, and is available in varying grades.

For a DIY hydroponic system, you will need a water reservoir and a pump. Your water reservoir should be placed out of direct sunlight.


Hydroponics is the art of growing plants without soil. There are many types of hydroponic systems and you can grow practically any type of plant using them. Some of the most popular systems are water culture, NFT, and ebb and flow.

Water culture is a popular home-growing method that places the roots of your plants directly into a nutrient solution. You can use perlite, gravel, Rockwool, or other materials.

A wick system is another hydroponic technique, which draws the nutrients from the solution to the plant’s roots. The drawback to this technique is that the roots may dry out if they are placed in a wet solution. Using a water reservoir with a lid prevents this from happening.

Aeroponics is the most high-tech of all hydroponic systems. It is a pump-driven system that uses a nozzle and diffuser to deliver oxygen to the root system. Although it can be expensive to build, it is effective in growing a wide range of plants.

This type of system is a great choice for smaller crops. But you must also take into account the amount of energy it requires.

If you’re planning to grow plants like tomatoes and lettuce, an NFT system is a good option. These systems use a submersible pump and reusable nutrient solutions. They are also well suited for bigger plants.

Ebb and flow hydroponic systems work by flooding the growing bed with a nutrient solution at certain intervals. Because this system is recirculating, you need to monitor the pH level of the solution to keep your plants healthy.

These hydroponic techniques come in all shapes and sizes. Some are simple and easy to set up, while others can be complex.


There are many different kinds of fertilizers on the market. You can get ready-made blends, or you can make your own. While there are some advantages to buying a nutrient solution, you’ll find that making your own can be less costly and much more convenient.

Using a water-soluble fertilizer is an efficient way to add nutrients to your hydroponic system. The key is to choose the right one. This will ensure that your plants are getting all the important nutrients they need.

One of the easiest ways to get a good dose of micronutrients is to use a seaweed formula. It is easy to prepare and can be used as a base recipe or boosted with growth enhancers.

Another cost-effective way to add nutrients to your hydroponic systems is with a liquid fertilizer. These are simple to use and come in handy when you need to mix up a nutrient solution in small batches.

Liquid fertilizers are usually the most expensive, because they have a high shipping cost. But you can save some money by using tap water instead of distilled or bottled water. Using tap water may have been treated with chlorine, which is harmful to some plants. To prevent the chlorine from lingering in your water, soaking it in a bucket for at least 24 hours is a good idea.

Some plants require certain macronutrients, like nitrogen and calcium, which are used in the production of new leaves and flowers. A lack of these nutrients can cause the leaves to become weak and curled.

Besides nitrogen and calcium, plants also need trace elements, such as potassium and magnesium. Adding the appropriate amounts of these to your hydroponic nutrient solution will allow your plants to thrive.

Drip irrigation

Drip irrigation is a type of hydroponic system that enables you to control the amount of water that each plant receives. It also makes growing plants more efficient.

When it comes to drip irrigation, there are a number of systems to choose from. This type of irrigation system is best suited for smaller gardens, but does require some work on the grower’s part.

A drip irrigation system is a simple way to provide your plants with a continuous source of water. It uses a pump to pump the water and nutrients up to the plants’ roots.

Generally speaking, a drip system is an efficient way to supply plants with the nutrients that they need. However, it is important to remember that the proper maintenance of a drip irrigation system is vital to its efficiency.

To properly maintain a drip system, you will need to check the pH levels of the reservoir and adjust the nutrient solution as needed. You should also monitor the flow of the drip lines to avoid overwatering or clogging.

For maximum efficiency, the drip system should be set up with a timer. The most effective timers are sophisticated enough to keep runoff to a minimum.

Depending on the plants that you are growing, you may be able to achieve greater yields by applying multiple applications of the water + nutrient solution. One study found that tomato yields increased by eight to twelve percent by applying multiple water applications.

The most cost-effective and efficient way to deliver nutrients to your plants is through a drip system. This type of irrigation method is suitable for a wide range of plants.

Unlike other hydroponic systems, drip irrigation can be done without soil. However, it requires a certain type of growing medium to maximize the efficiency of the system. Some of the most common varieties of media include perlite, coco coir, and rockwool.

Avoiding fungus gnats

Fungus gnats are an annoying pest. They have a short life cycle and multiply quickly. The best way to control them is through prevention. However, if you have an infestation, you may need to apply several insecticides.

Fungus gnats are members of the order Diptera. Their wingless bodies are about two to eight millimeters in length. They have black heads and long legs.

Fruit flies and fungus gnats can cause a lot of damage in indoor plants. While fruit flies are mainly found in the outdoors, fungus gnats are more of a problem inside.

Adult fungus gnats lay eggs in damp decaying leaves, clippings, or soil. These eggs hatch into larvae that feed on fungi and plant roots. It’s important to eliminate the eggs before the larvae can hatch.

You can kill fungus gnats by applying a solution of hydrogen peroxide. You can use a solution of four parts water and one part peroxide. Mix it up and spray it on the affected areas.

Fungus gnats can also be controlled by putting sand on the soil. This discourages the insects from laying their eggs. Instead, they will tunnel through the roots, wilting the plant.

If you have an outdoor garden, you can also use neem oil based products to control fungus gnats. These oils are very effective. But they aren’t as cost-effective as Bti.

One of the easiest and most effective ways to control fungus gnats is to rethink your watering routine. Watering from the bottom of the pot will keep humidity lower, which discourages the insects from laying their eggs.

If you do end up with an infestation, it’s a good idea to quarantine the affected plants. This will allow you to spot weak fliers and temporarily control the infestation.
