Floraflex 16/17mm MDS Tubing — Double-Layer Drip Manifold for Precision Irrigation
Best for: Growers building or expanding a hydroponic drip system who need reliable main-line distribution tubing
Our thoughts
This is the backbone of a proper drip setup. Double-layer construction keeps temperatures down and algae out. Punch holes where you need them, push drippers in, and you've got a system that's flexible, customisable, and doesn't leak. One a lot of growers use because it just works.
The Floraflex 16/17mm MDS Tubing is a double-layer polyethylene micro drip distribution line designed to act as the main manifold in hydroponic irrigation systems. The white outer layer deflects light and keeps temperatures down inside the tubing, whilst the opaque black inner layer blocks all light and prevents algae buildup. You punch holes into it, push micro drippers in where you need them, and it routes water and nutrients from your pump to every pot in your setup without pressure drop-offs or leaks. Simple, precise, and proven.
How it compares
Against other drip tubing options, this sits in the mid-to-professional tier for customisable systems.
- Double-layer construction beats single-wall tubing for temperature and algae control
- Punch-hole customisation gives you flexibility that fixed inline emitter hoses don't
- Polyethylene is more UV and chemical-resistant than vinyl alternatives
- Full compatibility with the Floraflex ecosystem of fittings and micro drippers
- 5 GPM flow rate handles mid-scale setups without pressure compromise
In short: you're getting professional-grade distribution tubing at a price that makes sense for serious growers who don't want to overpay for the name.
Usage guidance
The 16/17mm tubing works as your main distribution line across different system layouts:
Building your manifold
Use a hole punch to create openings where you need drippers. Insert micro drippers directly into the holes — no glue, no faffing. If you punch a hole you don't need, use a goof plug to seal it off.
Connecting to your pump
The tubing fits standard BSP-threaded fittings. Use male adaptors to connect to your pump or reservoir, tees to split lines for branching distribution, elbows to navigate corners, and straight connectors to join lengths together.
Flow and pressure
Rated to handle up to 5 gallons per minute per lateral line and a maximum of 80 PSI. For longer runs or higher flow rates, you may need to step up to larger diameter tubing — this is best suited to setups where you're distributing to multiple points within a compact space.
Maintenance
Polyethylene lasts for years with basic care. The dual-layer construction keeps algae from building up inside, which means less blockages and cleaner water delivery over time.

Who this is for
- Growers building a hydroponic drip system from scratch who want flexibility and control
- Anyone expanding an existing Floraflex setup with additional distribution lines
- Operators of mid-scale indoor growing operations where precision watering saves time and plant stress
- Growers who've had algae or temperature issues with single-layer tubing
- Budget-conscious builders who want professional-grade components without premium pricing
Particularly well suited to compact indoor spaces where you're running multiple drip lines from a single main manifold.
Our take
This is proper distribution tubing at a price that doesn't rinse your budget. The double-layer design solves real problems — heat and algae — that cost growers time and headaches further down the line. It's flexible, customisable, and works seamlessly with the Floraflex dripper ecosystem.
If you're setting up a drip system and want main-line tubing that handles the job without complications, worth picking up while clearance stock lasts. Does exactly what it should, day in, day out.
