Healthy plant roots are what helps a marijuana plant to grow and thrive since they are responsible for the retention of water, anchoring of the plant, absorption of nutrients and helping with vegetative growth of the plant. Therefore, you need to consider a grow tray that can offer the cannabis plant roots access to proper drainage to keep them from withering or dying. The hydroponic tray also needs to facilitate providing the plant roots with oxygen without overexposure through different styles of perforation. Your plants require well-aerated roots to function appropriately. Also, they should be in a position ready to absorb nutrients.

Types of Hydroponic Grow Systems

There are various types of hydroponic systems that differ in complexities and benefits. Even so, these systems perform the same function of introducing nutrients to the plants in a different way rather than using soil. The nutrients are added to a hydroponic system through passive and active methods. Passive methods make use of growing mediums to hold the water, oxygen, and nutrients required by the roots to develop. Active methods, on the other hand, focus more on the grower as they involve the consistent application of nutrients. Here are six major hydroponic systems in use today.

The Different Hydroponic Systems for Your Marijuana Garden

Aeroponics System

Aeroponics System

An aeroponics system works by transporting oxygenated water nutrient solution from the reservoir through misting valves that spray a fine mist into an encasement that contains roots that are exposed. This system introduces a high percentage of oxygen to the plant roots without continually soaking them in water. Even though the system may be costly to set up, it is highly effective on large scale marijuana farms as it supports vertical growth hence maximizing the plant growing space. It is essential always to ensure that the misting valves do not clog if you use this method. Your plants may quickly die when the roots stay without moisture.

Deep Water Culture System (DWC)


The Deep water system is one of the most common methods in the growth of cannabis. The plants hang on top of the nutrient solution. The system is best suited for beginners as it is cost effective and effortless to operate. Here, Cannabis is set in separate containers which are then placed in a grow tray which hangs over the water. There is an air pump in the water tank that oxygenates the water and adds nutrients so that the roots can absorb them easily. It is essential always to give the roots enough dry time whenever you use this method.

Wick System


This system does not contain any movable parts making it a hustle-free method to implement. It makes use of a wick made of cotton or yarn to introduce nutrients to the grow tray where the roots of the cannabis absorb easily. This method of growing plants is recommended for use only on smaller plants as the larger plants tend to up us more water finishing up the nutrient solution faster than the supply. You can use multiple growing mediums when using this method.

Drip System


The drip system is one of the best for commercial-scale aquaponics farms. Each plant has an individual dripper that delivers an equal amount of oxygenated water with nutrients solution. All the excess water that is not absorbed by the plants flows down through the growth medium to the reservoir where it is pumped back up through the dripper system. You can swap out plants or harvest very fast by only removing the dripper. The dripper system allows you to control the amount of nutrient solution that a plant needs. You are also in charge of the watering schedule of the plants allowing you can change the watering frequency by considering the needs of the plants.

Nutrient Film Technique (NFT)

Nutrient Film Technique

In the NFT method, oxygenated water that contains nutrients travels to the planting tubes from the reservoir. The technique uses a PVC tubing with a large circumference where it is placed at an angle of a slight decline to allow the nutrient solution water to flow down the drainage pipe passing by the roots before being recycled back to the holding tank. The nutrient-rich solution should not remain stagnant since it may lead to the growth of bacteria causing death to your plants. To prevent this from happening, always ensure that the pipe is at an angle that allows it to drain entirely. You should also remember that the density of the roots may cause clogging of the pipes leading to stagnation of the nutrient-rich water.

The NFT system allows you to add more plants and expand your grow by adding more holes on the planting tubes just as long as your pump and holding tank can take care of the extra work.

The EBB and Flow System


In the ebb and flow system, the roots of the plant are not all covered continuously by water just as it is for the DWC and NFT systems. Here, oxygenated water with nutrients fills up the grow tray that contains the growing medium and the plant. Once the grow tray is full, the pump switches off, and the water drains back the reservoir. The process involves continuous flooding to desired levels ensuring the roots receive large portions of oxygen in between the flooding. Denser mediums are best for this method as they will help with stabilizing the plants an ensuring that they do not topple and fall over. The best grow material for this method would be Rockwool. It is essential that to ensure the pump system keeps running at all times to ensure that the tray does not flood for more than 30 mins giving the plant roots time to breathe.
