Big Drippa Kit

0 review(s)

The Big Drippa is a gravity‑fed drip irrigation system that delivers reliable, low‑cost watering anywhere — perfect for areas without a mains water supply. Often compared to a hospital I.V. setup, it features a 10.5‑litre reservoir bag, 5 metres of irrigation tubing, and 6 fully adjustable drippers for controlled, efficient watering.

Designed for greenhouses and polytunnels, the kit includes fittings to attach directly to standard greenhouse extrusions. A full reservoir typically drains over 24 hours (depending on dripper settings), providing enough moisture for up to two days — ideal for weekends away.

Made from recycled PVC (bag and tubing) and durable polycarbonate drippers, the Big Drippa offers a simple, eco‑friendly way to keep plants healthy with minimal effort.

This Handy 5 Litre Pressure Sprayer is ideal for a range of tasks, such as spraying water, fertiliser, pesticides and detergents. There is a trigger to allow straightforward on/off control and an adjustable spray nozzle, from mist to cone to jet. The sprayer bottle features a wide neck to facilitate easy filling and the ergonomic pump handle ensures easy pressurisation; there is also a pressure relief valve. The bottle is translucent to allow you to easily check the fluid level. Comes complete with a carrying strap to help reduce fatigue.

The Porous Pipe Soaker Hose is the original and still the best low‑water irrigation solution. Made in the UK from recycled material to ISO9001 standards, it delivers gentle, precise watering for borders, fruit and veg beds, greenhouses, and cloches — while using up to 70% less water than traditional methods.

Water is released directly at the roots, reducing evaporation and cutting down on watering frequency. Suitable for gardens of any size, it works reliably even on sloping ground and can be cut to length as needed. Depending on soil type, water permeates approximately 50cm either side of the hose for even, efficient coverage.
