The Best Indoor Hydroponic System for Weed
What is a Hydroponic Reservoir?
Hydroponics is a method of gardening that grows plants by using water instead of soil. Hence, a hydroponic reservoir stores water, just like any other reservoir, for this purpose. It stores the nutrients that your plants will need. Furthermore, it provides a medium for the nutrient solution to actively get to your growing plant.
We know hydroponic gardening is tricky, as you have to maintain the right conditions that encourage growth. You have to control the temperature, oxygen and pH levels, and concentration of the nutrient’s solution. In simple words, a reservoir helps you manage the variables better.
This is why choosing the right reservoir is very important for successful hydroponic system.
A Hydroponic reservoir come in different sizes, shapes, and material to cover all your functional and aesthetic needs. So, let’s look at all the important things you need to know to make an informed decision.
Do You Need a Hydroponic Tank?
The water in a hydroponic tank acts as the blood in your body. The tank holds the necessary nutrient level that your plants need, while the water carried the nutrients to them. Therefore, maintaining the required water level is very important as it is the growing medium for your plants.
All working hydroponic systems have tanks. Even the hydroponic system kit available in the market always comes with a reservoir, which further reinforces its importance. So, why should your hydroponic system be without one?
The Perfect Size of Your Hydroponic Reservoir and Tub
We already established the importance of a hydroponic tub, but its size is as important. A smaller tub would mean each plant get fewer nutrients and water than required.
Hence, the size of the tub should be reflective of your plant’s needs and growth pattern. So, you need to gather information about your plants to correctly calculate their minimum water requirements. After getting familiar with your plants, you can use the following rule:
- One small plant requires 0.5 gallons
- One medium plant requires 1 to 1.5 gallons
- While one large plant requires 2 gallons
By simple arithmetic, you can calculate the water your system will require to choose a tub that best fits your needs.
Hydroponic Reservoir – Considerations
The hydroponic tank is the main organ of your system. It holds the life of your plants; hence, you need to manage it with care and caution. It can get complicated as there are several factors you need to keep in mind while handling your tank. No need to worry though we have you covered. Here are all the things that you need to know.
Use a Lid
It is always a good idea to use cover your tank. Firstly, it reduces the evaporation rate that maintains the water and pH levels. Secondly, the water is less likely to get dirty from debris, and lastly, it’s great for temperature regulation.
You should always monitor and regulate the temperature in your tank. Every plant has its ideal temperature, but most of them fall in the range of 63 to 72 degrees. The optimal temperature encourages faster growth of the plant, so you need to keep the temperature stable around this level.
Size of Hydroponic Reservoir
The size of the tank determines the amount of water and hydroponic nutrient it can carry. It should be able to hold the required level of water, for equal distribution of nutrients among your plants.
Cleaning of Hydroponic Reservoir
Neglecting your tank can spoil all the effort you placed to set it up. You should take care of it, or else the water can become harmful to your plants. Cleaning keeps oxygen and pH level stable, as well as prevent toxins from building up.
Furthermore, proper maintaining becomes vital if fungus starts to accumulate, which can alter oxygen and pH levels of the solution.
Use a Filter
A small addition of filters can be a valuable investment for your hydroponic reservoir. It can prevent unwanted fragments from mixing with the solution while keeping pests at bay.

Different Hydroponic Systems and Reservoirs
Essentially all reservoirs function as a storage unit for your nutrient solution, but they can have different placements in a system.
Although there are a few standard types of hydroponic systems, you can alter them around to fit your personal needs. Hence, a hundred or so variations exist in them. To make things easier for you, we have described a few basic systems that you can choose from as per your needs.
Ebb and Flow
In it, the reservoir is placed under the tray holding the plant. The tray is called the grow bed, which gets flooded intermittently with nutrient solution. Furthermore, the excess nutrient solution gets drained back to the reservoir, which also gives it the name flood and drain system.
You need to flood the grow bed after equally timed intervals, which depending on the types of your plants. A timer is used together with a pump, in the reservoir, to timely flood nutrient solution into the grow bed. The timer starts and stops the flood, which controls the flooding and draining.
You can use this system for a greater variety of growing mediums and plants. Moreover, its more efficient to use as your solution is less likely to be wasted.
Just like ebb and flow, the placement of the reservoir is underneath the plants. However, the nutrients are pumped and dripped from above through drip pipes. Hence, it is sometimes also called the top feed system.
It is the most commonly used system, as its efficient and operation is simple. You will also need a timer with your pump so that the solution reaches the plant timely through the drip lines.
It’s efficient in the sense that any excess solution finds its way back to the reservoir below it, and reuses the solution. Furthermore, the emitters used directly drip nutrients to the roots that further reduced the level of wastage.
Nutrient Film Technique (NFT)
Unlike the other systems, a small film of nutrients constantly gets pumped into the roots of the plants. Moreover, you won’t need a timer or a growing medium to set it. The nutrients from the tubes flow over the roots of your plant, suspended in the air.
The constant need to pump the solution is the core of the system that also makes it vulnerable to a power outage. In the case of a power outage, the roots can become dry and brittle, so you need to maintain the constant flow of solution to the roots.
The system also reuses the solution, after it passes through the grow bed, it returns to the reservoir placed underneath it. Furthermore, it can be conveniently placed anywhere with a power supply for the pumps to function constantly.
Deep Water Culture (DWC)
You need to take care of three things while using a DWC system those are oxygen, water, and nutrients. As the name suggests, plants grow in a pool of water with their roots submerged in the nutrient solution.
You need to properly manage the water level and the oxygen level in your tank. Furthermore, the nutrient you are using should be rich in oxygen and pair well with the oxygen level. Lastly, you need to make sure the tank holds enough water for a more stable nutrient solution.
Unlike the other system, it doesn’t expose your roots to air either drench them with a solution a few times daily. Hence, it is one of the easiest systems to manage, but it isn’t the most efficient.
It is the easiest and cheapest of all of them. However, the easy of not actively looking after it comes with a cost. It can’t support large plants and is by far the least efficient system.
It makes use of wicks to deliver water to the plant’s root from the reservoir through capillary action. Hence, it needs specific components like wicks and an aeration system to set up. Furthermore, it doesn’t make use of a net pot to hold the growing medium. Instead, it fills up the tray completely. The seedlings are then planted on it.
