Tanks & Reservoirs

What Are Tanks and Reservoirs?

Tanks and reservoirs are containers used to store water and nutrient solution in hydroponic systems. They act as the main supply point for irrigation and feeding, helping deliver consistent solution to your plants through the rest of the system.

In many indoor grow systems, the reservoir is the central point that everything else depends on.

Why Reservoirs Matter in Hydroponics

A good reservoir setup helps keep feeding more stable and manageable.

• Stores nutrient solution safely and efficiently
• Supports consistent irrigation and feeding
• Makes pH and EC monitoring easier
• Works as the central supply point for many systems
• Helps simplify maintenance and nutrient management

Choosing the right tank size and layout can make a big difference to system performance and day-to-day ease of use.

How Tanks and Reservoirs Are Used

Reservoirs are commonly used to hold prepared nutrient solution before it is delivered through the system. In recirculating setups, the solution may return to the same reservoir to be reused, while in other systems it may be fed out more simply depending on the configuration.

This makes the reservoir one of the most important parts of nutrient management in indoor hydroponics.

Tanks, Pumps and Irrigation Systems

Tanks and reservoirs are usually used alongside:

• Water pumps to move nutrient solution
• Pipe and fittings to connect the system
• Measuring tools to monitor pH and EC
• Nutrients and boosters to build the feed solution

This combination helps create a more controlled and efficient feeding environment.

Choosing the Right Reservoir

When selecting a tank or reservoir, consider:

• The size of your grow system
• The number of plants being fed
• How often you want to refill the solution
• The space available in your grow room

A properly sized reservoir helps reduce maintenance and keeps feeding more consistent between refills.

Reservoir Management and Plant Health

Keeping the reservoir clean and correctly balanced is essential for good plant performance. Nutrient strength, pH and temperature should all be monitored regularly to help avoid root-zone problems and nutrient issues.

This is why many growers use reliable monitoring equipment as part of the wider system.

FAQs

What is a reservoir in hydroponics?

A reservoir is the tank that stores water and nutrient solution for the hydroponic system.

Why is reservoir size important?

The right size helps maintain more consistent feeding and reduces how often the system needs refilling.

Do I need to monitor pH and EC in the reservoir?

Yes, regular monitoring helps keep the nutrient solution balanced and supports healthy plant growth.

What else do I need with a hydroponic reservoir?

Most systems also use pumps, pipework, nutrients and measuring tools alongside the reservoir.
