Good sprinkling cans for indoor plants include the Practican by Haws Bosmer, the Stack by Plastec Industries and the Indoor Pour and Store by OXO Good Grips, according to a review by RealSimple.com. Also recommended are cans by Dramm, Fiskars and Akro-Mils, as well as the U Can Watering System and the Blomus Stainless Steel, as reported by TheSweetHome.com.
A good indoor watering can dispenses water at an even pressure rather than allowing it to gush. The base of the spout should be at the bottom of the reservoir rather than the top to avoid water splashing and should allow for accurate watering to deliver the correct amount of water. The can should fit easily under a faucet for convenient filling and cleaning. A can with a 1 gallon capacity is generally adequate for indoor use without making the can too heavy.
A wide-mouth container is good for permitting water to stand before use to allow chlorine to evaporate. While a stylish and pretty watering can is preferred by some indoor gardeners who like to display the container, a practical design is less likely to allow water to drip or splash out. Also practical, some plant owners don't use commercial watering cans and prefer to use a pour-over coffee kettle or repurpose a milk jug, cat litter pail or wine bottle to carry water.
