AQUADRIP is a very simple, yet very effective patented self watering system when screwed onto most plastic bottles. AQUADRIP water heads have an adjustable dripper function, which can be used to control exactly how much water is used. You can use AQUADRIP indoors, outdoors, in the greenhouse, in pots, beds, borders, vegetable patches, tubs, grow bags & hanging baskets. The pack comprises of 6 water spikes complete with 6 adjusting flow-locks. AQUADRIP utilises disposable plastic drinks bottles of any size. These nifty little water spikes encourage people to recycle their plastic bottles in their garden. AQUADRIP also helps with plant hydration due to less water being evaporated before it is absorbed by the plant. The spike delivers the water straight into the soil where the plants roots absorb it. 10% from each pack of Aquadrip is donated to Oxfam.
