The Nucan is a lightweight, narrow profile plastic watering can that has a button at the top of the handle to control the flow of water.
The control valve reduces the degree to which you will need to tip the can and therefore helps to reduce arm strain.
Narrow, flatsided watering cans are recommended as they can be held closer to your body. Although the Nucan is quite large, if you only half fill it with water it can be used one handed.’
Particularly recommended for:
All disabled gardeners
