Raindrip Vinyl Tubing - Black - 1/4in x 100ft - Coiled

Extra-Flexible Vinyl Feeder Tubing for Tight Indoor Routing, 100ft

Standard polyethylene feeder tubing can be too stiff for the sharp turns and close container spacing common in indoor grow rooms, and forcing it around a tight bend risks a kink that chokes off flow. Raindrip's vinyl tubing uses a more pliable material at the same 1/4in diameter, so it bends around tight corners and container clusters without the memory that causes poly tubing to spring back or kink.

This 100ft black coil is sized for a full indoor grow area or container garden, and its black color helps limit light transmission into the line, which can otherwise encourage algae growth.

Key Features & Benefits

• More pliable than standard poly tubing — bends around tight indoor corners and container clusters without kinking or springing back.
• 1/4in diameter, 100ft coil — matches standard feeder-line sizing and covers a full grow area or container run from a single coil.
• Black color — limits light transmission into the tubing interior, helping suppress algae growth in the line.
• Compatible with standard 1/4in fittings — connects to common drip stakes, in-line drippers, and barbed connectors without special adapters.
• Rated for indoor and outdoor use — handles both close-quarters indoor routing and typical outdoor garden installation.

Who Should Use This Tubing

Indoor growers and container gardeners who need feeder tubing to route through tight spaces, around dense container clusters, or through indoor structures where rigid poly tubing is hard to navigate benefit most from vinyl's added flexibility. It works equally well in an outdoor garden bed where routing simplicity matters more than mainline rigidity.

Frequently Asked Questions

What is the difference between this vinyl tubing and standard poly tubing?

Vinyl tubing is generally more flexible at the same diameter, making it easier to route through tight bends and indoor spaces without kinking. Poly tubing tends to be stiffer and is more commonly used for outdoor mainline runs where rigidity helps keep the line in place.

Can this tubing be used outdoors as well as indoors?

Yes, it's rated for outdoor use in addition to indoor routing, though many growers choose it specifically for indoor setups where its flexibility is the bigger advantage. Outdoors, standard poly tubing is often preferred for long, straight mainline runs.

Is this tubing compatible with the same fittings as Raindrip poly tubing?

Standard 1/4in barbed fittings work with both poly and vinyl tubing of the same diameter. Because vinyl is more flexible, it's worth checking that the fitting seats fully and holds a leak-free connection after installation.

How do I keep algae from growing inside the tubing?

The black color already limits light penetration, which is the main driver of in-line algae growth, but periodic flushing still helps clear any buildup. Keeping fittings and end plugs seated properly also prevents light from entering at connection points.
