The 6W 300 l/h 1-Rotor Movement Pump keeps the nutrient solution in constant circulation within the indoor grow tank. With a 6W power consumption and a flow rate of 300 l/h , this compact agitator from Neptune Hydroponics prevents settling, homogenizes the mixture, and optimizes each irrigation system for precise watering of indoor grows .

The 6W 300 l/h 1 Rotor Movement Pump is designed to mix nutrient-rich water in small and medium-sized tanks, maintaining nutrients in uniform suspension and promoting stable EC and pH conditions.
The propeller generates a continuous current that breaks dead zones, reduces salt accumulation at the bottom, and increases oxygenation by facilitating gas exchange with the support of air diffusers.
The nozzle is submersible and attaches quickly to the tank wall using a suction cup and/or magnet , allowing you to direct the jet towards the area where you need to sweep away debris or improve circulation. With a low power consumption of 6W and a flow rate of 300 l/h , the unit operates for extended periods with a very low noise level, making it ideal for indoor spaces.
The 1-rotor format simplifies maintenance, minimizes points of failure, and offers gentle yet effective agitation, perfect for working tanks, DWC buckets, flood tables, and compact recirculation systems.
Integrated within irrigation accessories , this pump helps dissolve additives, stabilizes the mixture during resting periods, and reduces the effort required for each preparation.
Maintenance is limited to periodic cleaning of the rotor and checking the suction cup; two simple actions that maintain performance season after season.
An essential ally in any online grow shop looking for reliable solutions to improve irrigation consistency and root health.
In indoor growing , keeping the nutrient solution moving is key to preventing stratification and ensuring nutrient availability throughout the reservoir. The 300 l/h flow rate generates controlled turbulence that homogenizes the mixture without creating excessive foam, resulting in more active roots and a stable nutrient uptake rate throughout the day.
It is used to mix fertilizers, keep nutrients in suspension , prevent settling , and improve tank oxygenation . It also accelerates the dissolution of solid additives or liquid concentrates, helps stabilize EC/pH between waterings, and prepares the tank before watering indoor crops in DWC, RDWC, or ebb & flow systems.
Performance increases when combined with these irrigation accessories :
With this assembly, the tank remains "alive", ready to feed drippers, rings and tables with stable flow and homogeneous composition.
1) Choose a wall of the tank and fix with a suction cup and/or magnet at mid-height, directing the jet to sweep the bottom.
2) Ensure a clear space in front of the flow, avoiding obstacles that create hydraulic shadows.
3) Connect to the network, verify global volume circulation and adjust angle until the critical zone is covered.
4) Maintain continuous flow during preparation and intermediate periods between irrigations; in recirculation, select moderate intensity so as not to disturb sensors or the float.
5) Clean rotor and housing periodically to remove biofilm and small mineral deposits; check suction cup adhesion.
This protocol keeps the mixture active, reduces crusting, and improves irrigation uniformity across all connected plants.
