Grow1 Black Vinyl Tubing - 1/2-in ID - 5/8-in OD - 50 ft

Opaque Vinyl Line for Water and Air Runs - 50 ft Length

Clear tubing lets light into your nutrient lines, and algae follows. This black vinyl tubing blocks light, so the inside of the line stays darker and cleaner. The walls are thick and flexible, and the tube measures 1/2 in inner diameter and 5/8 in outer diameter.

At 50 ft, one length covers a small to mid-sized indoor layout: reservoir to manifold runs, air lines, or a few separate feed lines cut from the same roll. Larger commercial rooms will want to order several lengths.

Key Features & Benefits

• 100% opaque black vinyl — blocks light to discourage algae growth inside the line.
• 1/2 in inner diameter — matches fittings sized for 1/2 in ID tubing.
• 5/8 in outer diameter — a known outside size for planning clamps and routing.
• Thick, flexible walls — bends around corners and is durable in use.
• 50 ft length — cut to fit many runs from one piece.

Who Should Use Grow1 Black Vinyl Tubing

Growers building or extending hydroponic systems, from home gardeners plumbing a reservoir to commercial operators replacing feed and air lines.

Frequently Asked Questions

Q: What is this tubing used for?
A: It carries water or air in hydroponic systems. Typical uses include feed lines, drain lines and air lines.

Q: Why choose black over clear tubing?
A: Black vinyl blocks light, which discourages algae growth inside the line. Clear tubing lets you see the flow but admits light.

Q: What do ID and OD mean?
A: ID is the inner diameter, the open channel the liquid or air moves through. OD is the outer diameter, the full width of the tube including the wall. Here they are 1/2 in and 5/8 in.

Q: How do I choose fittings?
A: Pick fittings made for 1/2 in inner diameter tubing. Check the fitting maker's sizing before you buy.

Q: Can I cut it to length?
A: Yes. Cut it with a sharp blade for a clean, square end so fittings seat properly.
