The 16 mm semi-rigid PE tube in a 50 m roll is the backbone of any precision indoor irrigation setup. Designed to deliver water and nutrient solutions across your hydroponic, aeroponic, NFT, ebb-and-flow or drip systems, this polyethylene tube combines flexible routing with rock-solid pressure resistance. Selected by BloomLED, growshop expert for over 10 years, for its reliability and seamless compatibility with the 16 mm fitting ecosystem.

The 16 mm diameter provides enough flow to feed multiple drippers, sprayers or manifolds without noticeable pressure loss - ideal for multi-plant setups and medium to large grow rooms.
The black tube fully blocks light and stops algae growth inside the line: your nutrient solution stays clean, drippers don't clog, and maintenance drops dramatically.
The semi-rigid PE bends enough to follow the angles of your grow tent or room, yet keeps its shape once installed. Works with all standard 16 mm fittings - click-on or compression.
Treated to withstand UV from high-power horticultural lamps, this tube doesn't crack or yellow and stays reliable cycle after cycle, even in intensive LED or HPS environments.
The 16 mm specification refers to the outer diameter, the hydroponic industry standard. It is directly compatible with all 16 mm fittings on the market: T-pieces, L-elbows, straight connectors, valves, end caps, compression fittings and drip adapters.
How many drippers can I run on a 50 m line?With a properly sized pump (typically 600 to 1500 L/h for a standard indoor network) and 4 L/h pressure-compensated drippers, you can easily feed 30 to 80 drippers along the run, depending on elevation and layout. For very large installations, consider using a manifold.
Is the tube compatible with high-pressure aeroponics?This semi-rigid PE tube suits low and medium-pressure aeroponic setups (up to roughly 4 bar). For high-pressure aeroponics (above 7 bar), we recommend the high-pressure rated tubing from our dedicated range.
The first choice of demanding indoor growers: the BloomLED 16 mm PE tube delivers stable, clean and durable irrigation across every cycle of your grow.
