Rainwater Tank 300 Liters

Rainwater Tank 300 Liter Cheap Tank

This cylindrical tank offers a balanced combination of capacity and streamlined shape, ideal for hallways and corners of the technical room. The resistant and opaque plastic body reduces light entry and helps keep the water in better condition.

The lid limits evaporation and prevents dust or insects, while the lower tap makes it easy to connect directly to a hose, inline filters, or check valves.

With a 300 liter capacity, the Rainwater Tank 300 Liter Tank acts as a hydraulic buffer for scheduled irrigation, either by gravity or with a pump, supplying main lines of 16–25 mm and branches to 13/6 mm depending on the dripper.

The compact design (Ø68 x 130 cm) makes use of available height without taking up too much floor space, which is key in cabinets and rooms with furniture or vertical racks.

The top opening allows for easy dosing of nutrients and adjustment of pH/EC; once the mix is ready, the lower tap ensures controlled flow to trays, pots, or irrigation rings.

Compatible with diffuser stones to increase dissolved O₂ and with timers/controllers for added precision.

A practical solution in an online grow shop focused on efficiency, hydraulic cleanliness, and real scalability.

• pH/EC meters and liquid thermometer for continuous monitoring.

How is the Rainwater Tank 300 Liter Tank used?

1) Place the tank on a flat, level surface, away from direct intense sources.
2) Connect the lower tap to the chosen diameter (16–25 mm); install inline filter and check valve before branches.
3) Fill through the top opening; adjust pH/EC, add nutrients and homogenize with gentle stirring or recirculation.
4) Purge air and particles by briefly opening each branch; check for uniform flow at remote points.
5) Keep the lid closed to limit evaporation; record consumption and schedule refills/solution changes.
Technical tips: anchor hoses to avoid pulling, clean internal walls between cycles, and reserve a line for periodic substrate washing.
