Osmosis 400 Liters with Water Master Pump offers stable base water for indoor cultivation in compact spaces. Produces up to 400 L/day, integrates a pressure pump for constant flow and reduces impurities, chlorine, salts, and heavy metals. Available at Hydroponics Blanes, online grow shop with discreet shipping and advice from a trusted Grow Shop.

The Osmosis 400 Liters with Water Master Pump unit is aimed at small rooms and cabinets that require osmotized water for A/B recipes and daily irrigation with repeatable parameters.
The combination of prefilters (sediments and activated carbon) and reverse osmosis membrane generates a low EC/TDS permeate, with virtually zero chlorine and lower salt content.
The integrated pump stabilizes performance when the network pressure is limited or variable, maintaining production close to 400 L/day.
The use of pure water reduces nutritional blockages, protects beneficial microbiota, and extends the useful life of pumps, drippers, and irrigation accessories.
With standard connections and direct maintenance —cartridge changes at regular intervals and membrane replacement when the EC of the permeate increases or production drops—, the system quickly integrates into any manual or automated irrigation system to water indoor crops with uniformity and traceability.
In indoor growing water quality determines recipe stability, root health, and line cleanliness. Starting with low conductivity water allows precise adjustment of Ca/Mg and micronutrients, reduces precipitates in pipes, and keeps drippers stable for longer. The 400 L/day capacity covers tanks for daily cycles, occasional substrate flushes, and remixing without stopping tasks.
For a balanced setup, it is advisable to add graduated tanks (60–150 L), hoses of 8–12 mm, additional inline filters, check valve, and flowmeter to standardize liters per plant. A TDS/EC meter is essential to audit the permeate and decide when to change the cartridge. Integration with timers or shut-off valves allows automating tank refills, reinforcing the reliability of the irrigation system and consistency when watering indoor crops.
Operational tip: label the tank with batch, target EC, and mixing date. This practice improves traceability and repeatability between batches.
