Green Round Tank 200 Liters is a rigid and stable container, ideal for indoor cultivation that requires irrigation autonomy and homogeneous mixtures. Made of high-resistance plastic and including a lid, it protects the water from light and contaminants, becoming the center of the irrigation system.

This tank offers a capacity of 200 liters in a robust format of Ø70 x 75 cm and weight 3.1 kg when empty, making it easy to place before filling.
The body in green color with total opacity prevents light from entering, reducing algae growth and helping to keep pH and EC stable. The lid limits evaporation, dust, and insects, while the integrated tap speeds up purges, transfers, and solution changes.
Due to its volume, it is perfect for supplying several dripper lines, irrigation rings, micro-sprinklers, or NFT channels in domestic and semi-professional projects.
It is advisable to add a circulation pump or air pump to avoid static layers and deposits on the inner walls. The rigid tank line is also available in 300 L and 500 L, making it easy to scale the irrigation system as needed.
In the online grow shop of Hydroponics Blanes, trusted Grow Shop, it is found alongside a wide selection of irrigation accessories with discreet shipping and technical support.
For indoor horticulture, Green Round Tank 200 Liters guarantees enough autonomy for several daily cycles without constant mixing. The round geometry promotes a natural vortex during mixing, prevents salt build-up in corners, and improves nutrient homogeneity to water indoor crops precisely. The compact format (Ø70 x 75 cm) fits alongside benches, tables, and cabinets, keeping aisles clear for maintenance and control.
It serves as the main tank for water and nutrients, a hydraulic buffer to stabilize flow, a service tank for washing and rinsing, and a thermal reserve that cushions temperature variations. It connects easily to drippers, rings, micro-sprinklers, or NFT systems, ensuring a constant supply. The lid protects the mix from light and insects, and the opacity of the material helps preserve water quality. With a circulation pump or aeration via diffuser stone, oxygenation and internal circulation are maintained, improving nutrient availability and preventing stagnant odors.
Proper integration enhances the tank's performance:
