The 1.2 L/h Self-Compensating and Anti-Drain Dripper offers a reduced and consistent flow rate to automate the watering of pots. It is ideal for distributing water or nutrients in a controlled manner in indoor cultivation setups.

This brown dripper is designed to deliver approximately 1.2 liters per hour at each irrigation point, as long as the system operates under suitable pressure conditions.
The self-compensating mechanism regulates the output to limit differences between emitters placed at the beginning, middle, or end of a line. The anti-drain function helps retain water inside the pipes when the pump stops working, reducing circuit emptying and subsequent dripping.
This combination provides greater precision in cannabis crops fed through frequent irrigations or short pulses.
The compact format has approximate dimensions of 23 mm long and 13 mm in diameter, as well as a barbed outlet ready to connect compatible microtubing.
It can be integrated with tanks, pumps, filters, pipes, distributors, stakes, and other irrigation accessories.
The low flow rate allows for a gradual application, especially useful in small pots, rooted cuttings, young plants, or substrates that need to receive the nutrient solution without an excessively fast supply.
To maintain stable operation, it is advisable to filter the water, avoid mixtures with particles, and periodically check each emitter.
The 1.2 L/h Self-Compensating and Anti-Drain Dripper is an individual emitter intended for localized irrigation systems. The piece incorporates an internal mechanism capable of regulating water flow and maintaining a nominal flow of 1.2 L/h in the face of moderate pressure variations within the network.
Compensation improves uniformity between plants, which is important when a pipe feeds several pots or covers a considerable distance. Without this regulation, the first points could receive more water than those at the end. The self-compensating system reduces this imbalance and facilitates more regular hydration.
The anti-drain feature closes the passage when the pressure drops at the end of the cycle. In this way, the pipes remain filled for longer and need fewer seconds to distribute water again at the next start. This property is especially practical in short and repeated irrigations, where every second of operation affects the applied volume.
This dripper is used to deliver water or fertilizer solution directly to the root zone. In cannabis cultivation, it helps reduce manual watering, facilitates automation, and allows better control of the amount delivered to each pot. It also works as a grow accessory for indoor setups in tents, rooms, drain tables, coco systems, peat, rock wool, and aerated mixes.
The 1.2 liters per hour flow rate allows for indicative calculations. A 10-minute cycle will deliver about 200 milliliters per emitter, while a 15-minute cycle will deliver approximately 300 milliliters. These amounts are theoretical and may vary depending on available pressure, circuit cleanliness, manufacturing tolerances, or dripper condition.
A reduced flow allows the solution to be distributed slowly, promoting gradual wetting of the growing medium. This speed can help limit rapid runoff along the sides of the pot and allows for short irrigations during peak demand hours. The final volume should be adapted to the growth phase, plant size, pot capacity, temperature, humidity, and observed drainage.
Within indoor grow irrigation systems, this model is useful for circuits with numerous emitters, as individual consumption is limited. Even so, the pump must be chosen by calculating the total flow, head height, and the pressure needed to properly activate all points.
To install the dripper, you need to prepare a main pipe connected to the tank, pump, and a suitable filter. Then, make a clean hole in the pipe and insert the emitter inlet. The barbed outlet can be connected to compatible microtubing, usually directed to a stake placed on the substrate.
Before starting the crop, it is advisable to open the end of the pipe and let water circulate to expel assembly residues. Once the line is purged, close the ends and check the operation of each dripper. To verify uniformity, identical containers can be placed under several points for 15 or 30 minutes. Then compare the collected volume.
When there are significant differences, check the pressure, possible leaks, poorly inserted connections, or clogged emitters. The timer should be programmed after knowing the actual flow. It is also advisable to measure the drainage of several pots to ensure the chosen frequency matches the crop's needs.
Maintenance includes cleaning the tank, periodically washing the lines, and checking the filter. Fertilizers should be completely dissolved before entering the circuit. Do not insert needles, wires, or tools inside the dripper, as the regulating membrane could be damaged.
Buying the 1.2 L/h Self-Compensating and Anti-Drain Dripper allows you to create a precise irrigation network or replace damaged emitters. Before ordering, it is advisable to calculate the number of plants and the total flow. For example, a setup with 20 drippers will need to provide a theoretical total flow of 24 liters per hour.
At Hydroponics Blanes you will find components to complete the installation, such as pipes, microtubes, tanks, pumps, filters, valves, connectors, stakes, and timers. Our trusted Grow Shop offers materials to prepare circuits adapted to different grow sizes.
The brown model allows you to quickly identify the 1.2 L/h flow within a setup with various types of emitters. The compact dimensions of 23 × 13 mm make it easy to place in small spaces and leave room to organize several lines around a grow table.
The price of the dripper will depend on availability, quantity purchased, and active promotions. As it is a small piece, it is advisable to add several spare units for future expansions, maintenance tasks, or quick replacements. The online sheet shows the current price and available stock.
You can buy the 1.2 L/h Self-Compensating and Anti-Drain Dripper online at Hydroponics Blanes, a Grow Shop in Spain specialized in equipment for indoor crops. The store allows you to purchase all the circuit components in a single order and receive them through discreet shipping.
The 1.2 L/h Self-Compensating and Anti-Drain Dripper is a compact solution for applying water and nutrients at a slow rate, improving uniformity between pots, and reducing line drainage when the pump is turned off. A practical component for automating cannabis irrigation and organizing efficient installations in indoor grow spaces.
