75-liter round tank with lid is a compact and secure container for indoor cultivation. Made of opaque black polypropylene and includes a lid, which helps keep water and nutrient mix protected from light, insects, and dust. Ideal as the heart of a stable irrigation system in medium-sized spaces.

This cylindrical tank of 75 L offers a very balanced capacity-size ratio for cabinets, home greenhouses, and technical rooms. With height 63 cm and diameter 47 cm, it fits next to tables or benches without compromising passage.
The body in plastic (polypropylene) withstands work with liquid fertilizers, regulating acids, and additives, keeping the solution stable for longer thanks to the opaque black color that blocks light.
The included lid reduces evaporation and environmental contamination, making for a cleaner operation.
The round shape promotes natural swirling during mixing, minimizing salt deposits in corners and improving homogeneity, something key for watering indoor crops evenly.
This format works both by gravity and with a submersible pump and easily integrates into NFT, drip, or light recirculation setups.
In the online grow shop of Hydroponics Blanes, referenced as a trusted Grow Shop, it is among the most versatile irrigation accessories, with discreet shipping throughout Spain.
Within an indoor growing environment, the Round tank with lid 75 liters serves as the central tank for water and nutrients for one or several cabinets. The 75 L volume provides enough autonomy for several daily waterings, reducing preparation times. The lid keeps the solution protected between cycles and the opaque material limits algae growth, helping to stabilize pH and EC. The circular geometry facilitates a centered position for the submersible pump, reduces cavitation, and improves pumping performance.
It is used to store clean water, prepare nutrient solutions, and act as a hydraulic buffer in drip irrigation systems, rings, or micro-sprinklers. It also supplies channels in NFT systems, maintaining a constant flow to the roots. The lid protects against dust and insects, reduces evaporation, and helps maintain nutrient balance. With aeration via air pump and diffuser stone, the solution is better oxygenated, favoring ion availability and reducing stagnant odors. The set is especially useful for watering indoor crops precisely and repeating fertilization recipes without variations.
