Best Hydroponic Reservoirs | Hydroponic Tanks Reviews & Guide

If you are looking to start a hydroponic farm to grow marijuana, among the essential items you need to begin the project is a reservoir. The reservoir works as a storage for the nutrients solution that provides hydration and nourishment to the plants. There are different types of nutrient reservoirs in the market today all of which have different operational mechanisms.

Hydroponic Reservoirs

Reservoirs can come in any size and are built from any material. Some hydroponic systems house the plants and the reserver together while in other systems, the nutrient reservoir is separate and relies on tubing’s and a water pump to delivers the nutrients to the roots through regular intervals. When choosing a hydroponic nutrient reservoir, it is best to go for a bigger size that can carry large amounts of the nutrient solution required to feed your marijuana plants. Smaller nutrient reservoirs are prone to swings in the pH level, depletion of oxygen and nutrient fluctuations. It is essential to maintain the temperatures of the nutrient solution in-between 65 and 75 degrees. Any higher than that, the oxygen levels will decrease making the environment suitable for the occurrence of root rot. When the temperature drops further than the range, the plant will experience stunted growth. Small reservoirs make use of aquarium heater to warm up a nutrient solution. Here are three of the best hydroponic reservoirs in the market today.

The Top 3 Hydroponic Reservoirs for Growing Cannabis

Superponics Superponics-8 Hydroponic Reservoir System

Superponics Superponics-8 Hydroponic Plant Propagaton Reservoir System

The Superponics Superponics-8 Hydroponic Reservoir System is a favorite to many indoor cannabis growers. It helps your cannabis plants to grow five times faster than any other hydroponic method. It is safer and easier to use. The system helps your plants to thrive by combining the top feed watering with bottom feed oxygenation. It is a reliable growing method since there is more than one independent hydroponic grow system operating at the same time. The plants will still grow and thrive even one system collapses. The system leads to rapid growth rates and massive yields.  The reservoir comes with a lid in which both are custom molded and UV stable. It is easy to use and clean. All you need to do is plug it I and add water. It comes with eight nest cups that allow you to hold up to 8 plants. It has Eco series air pumps that provide air to the hydroponic systems. The pumps are strong and durable. They are very quiet and can operate without the use of oil. It has a water pump that is run by a magnetic rotor to provide 132 gallons of water per hour to the system. The hydroponic system comes with a light timer to help control the light changes in your indoor environment.

Superponics Superponics-16 Hydroponic Plant Propagation Reservoir System

Superponics Superponics-16 Hydroponic Plant Propagaton Reservoir System

The Superponics-16 Hydroponic Reservoir System is quite similar to the Superponics-8 Hydroponic Reservoir System as they both speed up the growth of marijuana five times more than any HYDROPONIC RESERVOIR system. It utilizes top feeding, deep water culture, and aeroponics systems. The main reason plants grow faster than on any other hydroponic reservoir is because two hydroponic grow systems are always running at the same time. Whenever one system breaks down, the other system continuously runs enabling the plants to grow and thrive. The plants receive top feed watering and bottom feed oxygenation that helps in the development of plants. It comes with 16 net cups each of 3 inches that give space for the growth of 16 new plants. It comes with potent yet silent Eco series air pumps that help to provide oxygen in the hydroponic system. It has a water pump that is powerful enough to accommodate 185 gallons of water per hour. There is an analog light timer present that helps to detect sunrise and sunset automatically.

Choosing A Reservoir Set Up

Floating or Water Culture

This reservoir allows plants to float above it with their roots taking in the nutrients from the reservoir. You can use this method in a basic indoor growing setting.

Wick

It is another basic hydroponic system where the reservoir is under the plants. The plants are in a growing medium, and thick cotton like ropes are used to funnel the nutrient solution for the reservoir to the growing medium. The solution flows upwards through the line by capillary action and ensures the growing medium is always moist.

Top Feed/ Drip

In this system, the reservoir is under the plants. It pumps the nutrient solution above the plants through drip pipes and later feeds the cannabis plants by use of emitters.  There is no wastage of nutrient solution as the excess flows back to the reservoir where it is pumped back again to the top maintaining the cycle.

Ebb and Flow

The ebb and flow system is a common and preferred method of use by most professionals. The reservoir is below the plants. The plants are placed on an open tray which is then flooded around four times in a day. The flooding solution drains to the reservoir. It is best if you have an overflow piping system to safeguard against excess pumping.

Nutrient Film Technology (NFT)

NFT has remarkable similarities to an Ebb and Flow system. Here, the reservoir can be placed anywhere as long as the pump is well functional and the excess nutrient solution flows back to the nutrient reservoir. In this method, plants are sitting in a tray and are fed the nutrient solution through a thin film of the solution that is accessible throughout the process.

Other Considerations When using a Reservoir

Always cover your hydroponic reservoir with a lid to reduce the evaporation of the nutrient solution and prevent any contamination problems. You do not want algae and pests to find their way to your cannabis plants as that would be detrimental to the quality of marijuana you produce. Also, ensure that you remember to clean your reservoir periodically to reduce the chances of molds pests or any other issues from occurring. While maintaining the hydroponic nutrient reservoir, you should keep the proper levels of pH and EC of the nutrient solution. Make sure that it lies in the range of 5.5 and 6.5.

If you do not have a filter for your hydroponic system, it would be a good idea to purchase one. A filter helps to prevent materials from flowing into the nutrient reservoir. Also, ensure that you clean it often to prevent the build-up of pests.

You may think of adding an extra reservoir to your hydroponic system. The purpose of the additional nutrient reservoir would be to provide and easy to access the supply of water. It is especially helpful to cannabis growers since the water releases chlorine and other chemicals after standing overnight bring it to a pH level that is closer to neutral than water straight from a tap. The water is also at room temperature which makes excellent conditions for the development of roots.

Frequently Asked Questions

What should be the size of a hydroponic reservoir?

When you grow your cannabis plants hydroponically, ensure that the small plants receive a ½ gallon of water, medium plants to receive 1 ½ gallon of water and large plants to get 2 ½ gallons of water. We recommend that you acquire a reservoir that is double the size of what you require to get the best plant results.

What temperature is the best in a hydroponic system?

Researchers claim that for a nutrient solution to be effective it should be kept between 65 and 80 degrees Fahrenheit.

Conclusion

A hydroponic nutrient reservoir helps you to store and prepare a nutrient solution. When choosing a nutrient reservoir, you should focus on acquiring a large one rather than a smaller one since it will be easier to maintain the pH, nutrient concentration and temperature. Also, you should ensure that you acquire a lid for the reservoir to prevent foreign materials from getting into the nutrient reservoir and causing any unnecessary damage.  Since most reservoirs do not come with their cover, you can purchase it separately. Ensure that the nutrient tank lid black or opaque too. It helps to prevent the nutrient solution from growing algae while in the reservoir. We hope that with the information above you can make the right decisions when growing your cannabis plants using a hydroponic system.
