The 2 L/h Self-Compensating and Anti-Drain Dripper allows you to distribute water and nutrient solution with a stable flow rate in localized irrigation systems. A practical option to automate indoor cultivation and maintain regular hydration in each pot.

This irrigation emitter is designed to deliver approximately 2 liters per hour when operating within the appropriate pressure range of the system.
The self-compensating technology helps balance the flow between different points on the same line, even when there are moderate pressure variations, long runs, or small height differences.
The anti-drain function reduces pipe emptying when the pump stops, preventing subsequent dripping and enabling faster starts in scheduled irrigations.
These features are especially useful in cannabis crops with automatic irrigation, where it is important to apply controlled amounts of water or fertilizer solution to each plant.
The red model features a carpenter-type outlet and has approximate dimensions of 23 mm long and 13 mm in diameter, so it takes up little space in the setup.
It can be integrated with main pipe, microtube, connectors, irrigation stakes, and other irrigation accessories, always checking compatibility between diameters.
As with any low-flow emitter, it is advisable to install a filter, keep the tank clean, and periodically check for possible accumulations of salts, particles, or fertilizer residues. Basic maintenance helps maintain irrigation regularity and prolongs the useful life of the entire system.
The 2 L/h Self-Compensating and Anti-Drain Dripper is a drip irrigation emitter that regulates water output to maintain a supply close to 2 L/h. The internal membrane compensates for pressure variations within the limits allowed by the system, ensuring that drippers placed at the beginning and end of the line work more uniformly.
The anti-drain function acts as a shut-off when the pressure drops after turning off the pump. In this way, the water remains in the circuit for longer and reduces emptying through points located at lower heights. This property provides advantages in pulse irrigations, short-duration schedules, and setups with several pots, since each cycle can start more quickly and with fewer differences between plants.
Due to its compact size and reduced flow, it fits as an indoor growing accessory in grow tents, grow rooms, drain tables, and propagation areas. It can also be used in orchards, gardens, nurseries, or localized irrigation systems where it is necessary to control the applied volume.
This dripper is used to deliver water or nutrient solution directly to the root zone of each plant. In a cannabis crop, it helps automate irrigation frequency, reduce manual tasks, and distribute water more evenly between pots. The 2 liters per hour flow allows you to easily calculate the approximate amount applied: a 15-minute cycle will deliver about 0.5 liters per dripper, provided the pressure, emitter condition, and setup are correct.
Pressure compensation is useful in lines with several emitters, as it limits flow differences caused by distance from the pump. The anti-drain function also helps prevent lower pots from receiving additional water after the cycle ends. For this reason, this component can be part of indoor grow irrigation systems aimed at coco, peat, light mixes, rock wool, or other substrates compatible with fertigation.
To obtain good results, time and frequency should be adapted to pot size, development stage, temperature, ambient humidity, substrate retention capacity, and obtained drainage. The nominal flow does not replace direct observation of the plants or measurement of the drained volume.
The installation begins by preparing an irrigation line connected to a tank and a pump capable of generating the minimum pressure necessary to properly activate the emitters. Then the main pipe is drilled with a suitable tool or the dripper is connected using the compatible adapter. The carpenter-type outlet can be connected to a microtube and a stake to direct the water to the surface of the pot.
Before placing all the drippers, it is advisable to carry out a test with several identical containers. The system should run for a set time and then the volume collected at each point should be compared. This check allows you to detect leaks, faulty connections, low pressure, or clogged emitters. When the difference between containers is small, irrigation can be scheduled using a timer.
It is recommended to incorporate an irrigation filter before the dripper line. It is also useful to shake or recirculate the nutrient solution, control the pH, and avoid mixtures with precipitates. At the end of each crop cycle, the pipes can be cleaned with a product suitable for irrigation systems and rinsed with water. Wires or sharp objects should not be inserted into the dripper, as the internal membrane could be damaged.
Buying the 2 L/h Self-Compensating and Anti-Drain Dripper allows you to expand, repair, or assemble a localized irrigation system for indoor growing. Before placing the order, it is advisable to calculate the number of plants, the number of emitters per pot, the total required flow, and the pump capacity. For example, twenty 2 L/h drippers represent a theoretical total consumption of 40 liters per hour.
At Hydroponics Blanes you will find materials to complete the installation: tanks, pumps, pipes, microtubes, filters, connections, valves, timers, and other irrigation accessories. As a trusted Grow Shop, we offer specialized advice to choose compatible components and prepare a setup adapted to the available space.
The price of the dripper may vary depending on the unit, sales format, and availability. As it is an economical part, it is easy to have additional emitters for future expansions or replacements. Checking the updated price on the product page allows you to know about promotions, stock, and available purchase options.
