A flexible 4 × 2.5 m insulated air duct designed for hydroponic and indoor‑grow setups. The kit includes one 102 mm (4 in) PVC‑foil vent hose and two stainless‑steel clamp clips that adjust from 90 mm to 110 mm, giving a secure fit on most standard vent outlets.
Why it works for your grow room
- Quiet operation – an aluminium‑foil liner dampens noise and limits heat transfer from fans or exhaust units.
- Durable construction – a tear‑resistant PVC outer sleeve protects the hose while an internal steel wire coil keeps it rigid yet bendable.
- Easy installation – the hose extends to 2.75 m (about 9 ft) with 0.25 m of slack for positioning, then retracts back to its original length.
- Improved air quality – the insulated pathway helps reduce condensation, mold and airborne germs, keeping your plants healthier.
