Hydroponics is growing plants without soil as the plant media. You probably assume that soil is indispensable for plant growth, but we are about to change your mind.
The different functions of soil can be recreated using other materials. Basically, soil provides support for plants because it develops a physical structure for the roots to hold on.
In a hydroponic system, the physical support provided by soil can be replicated with a number of materials and structures.
The choice of a good hydroponic system is huge in today’s market. However, we have been able to select five top rated products for your selection.

What to Look for in a Hydroponic System
There are a number of things you have to look for when shopping for a hydroponic system, and they include:
Hydroponic Methods
There are several hydroponic methods or techniques you can consider.
- Aeroponics
This is the most advanced hydroponic technique on the market. It uses a little amount of growing medium.
Therefore, the plant roots hang in the air and are misted with nutrient water. This method is ideal for growing small plants and herbs.
Bigger plants are not easily supported by this technique due to the lack of substrate. Usually, the roots are held by a contraption.
What’s most impressive about this technique is the fact that it is equipped with a timer that is connected to a pump that automatically mists the roots.
Aeroponics systems are remarkably lightweight because they barely use a potting medium. These systems are suitable for small spaces.
- Deep Water Culture (DWC)
The aeroponics technique is considered the most advanced, but the deep water culture is the most popular in the current market.
Deep water culture systems are usually fitted with plant sites/holes and a reservoir. The roots are supported by a growing medium, such as hydroton clay.
It is normally important to use a growing medium that does not retain moisture since the plant roots are constantly submerged in the solution.
DWC is probably the easiest system to set up, making it a suitable choice for inexperienced growers. You can even build your own deep water culture unit.
- Drip Ring Technique
This is a simple technique that is popular among growers. It uses a timer that controls a submerged pump.
Usually, the pump is connected to small pipes that are dipped to the roots of the plant. Normally, the pipes are fitted with nozzles that are easy to adjust to control the amount of water.
The pump is automatically turned on by the timer so as to provide a measured amount of the nutrient rich solution to the plant.
With this technique, you are advised to use a soilless mix so as to prevent water from accumulating which can cause the roots to rot.
In most cases, drip ring systems use rocks to support the plant. The amount of water required for this method is minimal, making it the most cost-efficient technique.
- Ebb and Flow
Basically, this is a sub-irrigation technique. The nutrient solution is pumped into a shallow growing bed to a depth of around an inch for about twenty minutes and allowed to drain back to the tank.
If you are a first time gardener, then this is the ideal choice for you because it is easy to set up. The number of times the pump is switched on depends on the specific plant needs.
The ebb and flow technique use a loose growing medium, which can easily get stuck in the pump, causing power outages.
Growing Medium
The second most important consideration is the growing medium. The ideal growing medium is supposed to hold oxygen, water, and nutrients, and support the root system. The most popular and reliable hydroponics growing media are:
- Hydroton
Hydroton is made from blends of different clays fired in an open furnace to get rid of heavy metals as well as other contaminants.
Hydroton pellets have good water retention and pH sustainability that protects the plants against excess acidity.
Some of the top rated hydroponic systems use hydroton, and they normally have few insect problems, but may suffer from green algae.
- Rocks
You can use different types of gravel or rocks as your grow medium. This is by far the most economical grow medium.
Some of the finest rock materials you can consider include river rock, lava rock, and pea gravel. Rocks are highly aerated.
- Coco Coir
This is a relatively new growing medium made of fibers from the husks of coconuts. Coco coir can vary from one manufacturer to another.
Coco coir has good water to air ratio. This medium is capable of holding water for quite a while between watering.
It does also have good pH sustainability and slower drainage and drying rate. The only problem is that coco coir is vulnerable to insect infestation.
- Rockwool
This medium is made from natural rocks that have been melted down and blown into mineral fibers with unparalleled water to air ratio.
It has remarkable water retention and its extreme porosity makes it drain well. This medium has superior pH sustainability.
Rockwool is available in different sizes, mats, and plugs for propagation. The alkaline nature and porosity of Rockwool make it subject to the aggressive growth of mildews, molds, and algae.
Top 5 Hydroponic System for Growing weed
#1 Bubble Boy (DWC) Hydroponic Bucket System
The Bubble Boy is a practical and affordable way to grow plants hydroponically. The Bubble Boy system uses what is known as deep water culture (DWC).
In DWC systems the roots are suspended in a highly oxygenated, nutrient rich water. This is a perfect choice for a green thumb or a little green.
Using high quality hydroponic fertilizers, the roots don’t have to convert nutrients for the plants to use. This allows your plants to grow faster and larger.
Aeration is an important feature of a DWC system. That is why the manufacturer has included a large dual outlet air pump along with a high quality air stone.
The air pump and the air stone provide better diffusion and increased oxygenation. This combination guarantees the production of healthy plants in a short period of time.
The Bubble Boy system is also equipped with a durable black reservoir as well as a factory-pressed lid. The lid helps to protect the plants against algal growth.

These systems offer the potential for faster crop growth. Hydroponics feed roots in a precise blend of important nutrients with a balance of oxygen and water.
Hydroponics use less water because you may reuse any irrigation water not directly consumed by the crop. Evaporation can be reduced by covering the water reservoir.
With a hydroponic system, no need for weeding or herbicides. Therefore, your plants will never suffer the effects of harmful herbicides.
