Pipe and fittings for hand-watering and topping up
Not every tent needs a full irrigation system — a lot of growers just need pipe and connectors to top up pots, run a hose from a reservoir, or plumb a single dripper by hand. Our Kool Tube range covers 13mm, 19mm and 25mm bore (from £1.30) for exactly this, plus a hose connector set (£4.95) to join lengths together or fit a tap without cutting and re-fitting pipe every time.
4mm air line (£0.30) is the smaller-bore option for air pumps and single drip points rather than bulk water transfer — don't confuse the two when you're putting an order together.
Buying advice
Buy pipe by the metre rather than guessing — measure the actual run from reservoir to pots before ordering, since offcuts are wasted money either way. If you're plumbing a full AutoPot or recirculating setup rather than topping up by hand, see pipe for hydroponic systems for the bigger-picture range. Free UK delivery kicks in at £50, and pickup from our Wembley store is always free.
