Description
Two hundred metres of black 4mm airline, so the tubing never grows algae
A 200 metre reel of 4mm internal-diameter airline in black, distributed by Hailea. 4mm bore, 6mm outside, is the standard size for air stones, manifolds, non-return valves and tees, so one reel feeds every pump in the room. The flexible, cold-resistant PVC stays kink-resistant and hard-wearing, and because it is black rather than clear, light cannot reach the inside of the line and algae does not grow in it - the reason to choose black in a lit grow room.
Key Benefits
- 4mm internal, 6mm external - fits every standard stone, manifold tail, tee and check valve
- Black - no light in the line, no algae in the line
- 200 metres on a spool - cut to length, no offcuts wasted
- Kink-resistant, cold-resistant PVC - stays flexible where it drops into a cool reservoir
How to Use
- Cut to length from pump or manifold to each stone, allowing slack for the lid to lift.
- Fit a non-return valve in each run if the pump sits below the water line.
- Push-fit onto 4mm barbs; warm the end in hot water if a barb is tight.
