There’s a long-standing debate among marijuana growers about whether not hydroponics or soil is the best way to grow plants. Regardless of where you stand, it’s undeniable that hydroponic systems have their benefits.
Soil provides support for plants because it develops a physical structure for the roots to hold on. But hydroponic systems are hugely popular for growers who want to have more control over the growth process. In a hydroponic grow system, the physical support provided by soil can easily be replaced.
A Selection of Reliable Hydroponic Systems:
Bubble Boy (DWC) Hydroponic Bucket System
The Bubble Boy DWC bucket system 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 highly oxygenated, nutrient-rich water.
Using high-quality hydroponic fertilizers, the plant’s roots don’t have to convert nutrients for the plants to use. This allows your plants to grow faster and more abundant. Aeration is an essential feature of a DWC system, which is why the manufacturer has included a sizeable dual outlet air pump within this system as well as an 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. The Bubble Boy system is also equipped with a durable black reservoir as well as factory-pressed basket lids. The lid helps to protect the plants against algal growth.
- The system is highly oxygenated and nutrient-rich
- Comes with hydroponic fertilizers for fast growth
- Superior aeration allows for better diffusion
- Factory-pressed lid protects plants against algal growth
- Large bucket capacity
- Bucket may leak
- Does not have enough hydro stone for some larger grows

What to Look for in a Hydroponic System
There are several things you have to look for when shopping for the best hydroponic system, including the hydroponic method and the growing mediums you want to use.
There are several hydroponic methods or techniques you can consider. Before choosing a system, make sure that you know which way feels the most comfortable for you to use.
- Aeroponic System
This is the most advanced hydroponic technique on the market. It uses a small amount of growing medium, which can save you money in the long run. With aeroponic systems, the plant roots hang in the air and are misted with nutrient water. This method is ideal for growing smaller plants and herbs.
This technique does not easily support bigger plants due to the lack of substrate. Usually, the roots are held by a contraption with large plants.
Most systems that use this technique are equipped with a timer that is connected to a water pump that automatically mists the roots. Aeroponics systems are remarkably lightweight because they barely use a potting medium. These grow 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 technique for indoor cannabis growers.
Deepwater culture systems are usually fitted with plant sites/holes and a reservoir. The roots are supported by a growing medium, such as hydroton clay pebbles. With DWC systems, it’s essential to use a growing medium that does not retain moisture since the plant roots are always submerged in the solution.
DWC is probably the most straightforward 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
The Drip Ring Technique is a simple technique that uses a timer which controls a submersible pump. Usually, the pump is connected to small pipes that are dipped to the roots of the plant. Typically, the pipes are fitted with sprayers that are easy to adjust to control the amount of water.
The pump is automatically turned on by the timer to provide a measured amount of the nutrient-rich solution to the plant. With this technique, you are advised to use a soilless mix 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 System
Ebb and Flow is essentially 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 uses a loose growing medium, which can easily get stuck in the pump, causing power outages.
The second most important consideration when choosing a hydroponic system 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 is made from blends of different clay pellets fired in an open furnace to get rid of heavy metals as well as other contaminants. Hydroton pellets have excellent water retention and pH level sustainability that protects the plants against excess acidity. Some of the top-rated hydroponic growing systems use hydroton, and they usually have few insect problems, but may suffer from green algae.
You can use different types of gravel or stones as your grow medium. This is by far the most economical grow medium. Some of the best rock materials to use include river rock, lava rock, and pea gravel. Rocks are highly aerated.
- Coco Coir
This is a relatively newer 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 and is capable of holding water for quite a while between watering. It also has good pH sustainability and slower drainage and drying rate. The only problem is that coco coir is vulnerable to insect infestation.
This medium is made from natural rocks that have been melted down and blown into mineral fibers with unparalleled water to air ratio. Rockwool has superior pH sustainability and remarkable water retention. Its extreme porosity makes it drain better than other mediums.
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.
For people who want to grow marijuana indoors, soil can be messy and too hands-on for indoor grow spaces. Hydroponic systems offer the potential for faster crop growth and more seamless growth cycles since they feed roots with a precise blend of essential nutrients with a balance of oxygen and water.
Hydroponics also use less water because you may reuse any irrigation water not directly consumed by the crop. With a hydroponic system, no need for weeding or herbicides. Therefore, your plants will never suffer the effects of harmful herbicides and be able to nurture their cannabinoids and terpenes.
We hope this article gave you some insight into the benefits of hydroponics systems and whether or not hydro is the right medium for your grow style.
