Y-derivation for irrigation allows you to split a flow into two lines quickly and safely, optimizing the irrigation system in indoor cultivation. Made of strong plastic and black color, it facilitates simultaneous tasks to water indoor crops with precision and less working time.

The Y-branch for irrigation from Garden Leaf is a branching connector designed to multiply coverage without increasing the total flow rate of the equipment.
Its “Y” geometry connects three hose sections and distributes the flow from one inlet to two outlets, stabilizing the pressure if accompanied by sector valves or reducers.
The black technical plastic body offers mechanical and chemical resistance to fertilizers, pH regulator acids, and common biostimulants.
In drip, micro-sprinkler, or irrigation ring installations, this piece helps to zone benches, feed two rows of pots, or divert to propagation trays without installing a complex manifold.
Assembly is straightforward: simply insert hoses by pressure or use compatible fittings to ensure watertightness. Due to its simplicity, it is a key element in modular irrigation accessory kits.

In indoor growing, the Y-branch for irrigation allows you to create two independent sectors from a single main line: for example, vegetative and flowering in different tents, or two heights on the same bench. The branching favors shorter runs, reduces pressure losses, and makes it easier to balance flow rates when each branch includes pressure-compensating drippers. Combined with a timer and suitable filters, it provides uniformity in the delivery of nutrients and water, supporting pulse irrigation strategies that stabilize pH and EC in the substrate.
It is used to split a line into two branches and feed different areas of the room or technical area. It is useful for separating crops with different water demands, creating bypasses to auxiliary tanks, or adding a second line to disc/osmosis humidifiers with independent control. It also speeds up maintenance tasks: while one branch irrigates, the other can be purged or primed without stopping the entire circuit. In NFT setups, it helps to divert the solution to two parallel channels, maintaining a constant and homogeneous flow rate.
To get the most out of the Y-branch for irrigation, it is advisable to integrate:
The entire ecosystem of irrigation accessories can be found at Hydroponics Blanes, with compatibility guides and discreet shipping.
1) Measure the hose diameter and choose the compatible “Y”.
2) Cut the main line and attach it to the inlet of the “Y”, ensuring good insertion.
3) Connect the two outlets to each branch; add a shut-off valve per outlet for fine adjustment.
4) Purge air by opening both lines; check for leaks during a test start.
5) Balance flow by partially closing the line with higher pressure until the drip is equalized.
6) Install a filter and, if necessary, a check valve to prevent unwanted returns.
7) Schedule irrigation according to the crop phase and plant density to water indoor crops regularly.
This process reduces installation times compared to complex manifolds and allows future extensions without redoing the main circuit.
The price of the Y-branch for irrigation varies according to brand, diameter, and connection format. The Garden Leaf version stands out for its cost-performance ratio and compatibility with hoses commonly used in technical horticulture. Check packs with gaskets and valves to optimize your budget.
