Watering can for indoor plants on a dry windowsill

Updated: October 2026

A jug from the sink soaks the windowsill, and a garden can is worse, because the spout is short and the body holds far more than a pot can take. A watering can for indoor plants in this set is a long spout and about 0.6 to 2 litres, filled where the tap can reach the hole. It is not a 6.5 litre or 10 litre round brought indoors. Peter F. used the amazon.co.uk listings captured on 15 October 2026. Prices and the other cans are on the [watering can comparison](/hub/garden-watering/watering-can).

About 0.6 to 2 litres

Haws says 1 litre suits most sink fills, and that 2.25 litres may need tilting under a low bathroom tap. The English Garden puts a narrow spout on the windowsill. The band used here is about 0.6 to 2 litres. A full litre is about 1 kg of water. A full 6.5 litre can is over 6 kg. In this set that band is the FERRIS 1 litre, the ANGIX 1 litre, and the MEETOZ 1.8 litre. There is no 0.6 litre can among the ten ASINs. Haws sells one, outside this comparison. Three pots are a 1 litre job. A conservatory bench can justify 1.8 litres.

A long spout, and a hole the tap can reach

The spout has to reach the compost while the body stays clear of the sill. A short spout makes you tip early. The FERRIS and the ANGIX list a narrow long spout and do not itemise a rose. The RHS wants water at the root zone. A rose is for seed. The MEETOZ nozzle comes off for a stream. The handle should not cover the hole. One small-can FERRIS review describes an opening that is not under the handle. One MEETOZ review describes a bathroom-tap fill. Try a larger indoor can empty before you commit to 1.8 litres under a low tap.

The indoor cans in this set

The FERRIS 1 litre, ASIN B0F21TRPTF, is £6.49 and 80 g. It is 4.5 from 605 reviews and does not itemise a rose. The review file overlaps the 6.5 litre FERRIS listing, so use comments that name a 1 litre can. It is the lowest price for a short indoor round, and it runs out after a few pots. The ANGIX, ASIN B09XK9YB75, is £7.10 and 70 g. It is 4.4 from 2,233 reviews, and that sample mixes in rose heads and larger cans. The plastic arrives dented in a bag. The extra 61 pence is a larger, mixed count. The MEETOZ, ASIN B0957D8CCT, is £9.49 and 1.8 litres, with a detachable shower nozzle. The title also prints 60 oz and 1/2 gallon. It is 4.5 from 88 reviews. The nozzle leaks onto tabletops in several reviews. Check the joint over the sink first.

Leave the garden cans outside

A full 6.5 litre can is over 6 kg. The Zuvo in this set, ASIN B0CSG437DR, is that outdoor can, not a 1.8 litre Zuvo from search. The Geli title says 10 litres, and reviews say the handle can block a kitchen tap. None of those is the default for a windowsill. The PHX Grove is 3.8 litres at £23.99. It can suit a greenhouse shelf, and it is large for a sill. The printed dimensions are far too small to trust. Patio size belongs on the watering can buying guide. For the sill, start at 1 litre. Rose up for seed is how to use a watering can.

Common questions

How many litres for houseplants?
About 0.6 to 2 litres. One litre is about 1 kg of water, which is a few pots. About 1.8 litres stays under 2 kg and covers a longer indoor round. This set has 1 litre and 1.8 litre cans, not a 0.6 litre can. A 6.5 litre can is over 6 kg when full and is the wrong default indoors.
Do I need a long spout?
Yes, if the pot sits against a wall or the foliage overhangs the rim. A long narrow spout lets you place a stream on the compost and keep the body off the sill. The FERRIS and the ANGIX are built that way, without a rose in the parts list. The MEETOZ has a long spout and a nozzle you can remove. A short garden spout makes you tip too early.
Will it fit under a kitchen or bathroom tap?
It fits if the handle does not cover the hole and the spout does not hit the tap before the can is under it. One small-can FERRIS review describes an opening that is not under the handle. One MEETOZ review describes a bathroom-tap fill. A larger indoor can may need tilting under a low tap. Try it empty. A Geli-sized handle is the one reviews say blocks a kitchen tap.
Do I need a rose indoors?
You need a rose for seed and for a fine spray. You do not need one for a stream onto compost, which is most houseplants. The 1 litre cans here do not itemise a rose. The MEETOZ does, and reviews say that nozzle can leak onto a table. If you sow indoors, the RHS also allows you to water the pot from below instead of forcing a coarse rose onto seed.
Is the 6.5 litre FERRIS the same product as the 1 litre FERRIS?
No. They are separate listings, B0GSS227YS at 6.5 litres and £8.99, and B0F21TRPTF at 1 litre and £6.49. The saved review text overlaps, which is why a comment can describe a tiny can on the larger page. Buy the 1 litre listing for houseplants. Do not assume the 6.5 litre rose is in the 1 litre box.
