Single sticks come in three lengths, and the length is set by the pot: small for pot sizes 2, 2.5 and 3, medium for 3.5 to 6, large for 6 to 12. Each one is sold on its own in green, white or black, so a single stick suits one plant you want to watch closely or a test before you equip a whole room. Packs of the same sticks sit in the next section.

What sets the Sustee moisture meter apart
It stays in the soil
The Aquameter is a leave-in soil moisture meter. It is pushed into the pot once and left there, unlike other moisture meters that are taken out after each measure. A quick look along a row of pots is enough to see which ones are dry.
A color signal instead of a dial
The tip of the stick changes color depending on what the core senses: blue while the soil is still wet, white once it has dried and the plant needs water. There is no scale to interpret and no battery required, which keeps the water indicator readable for anyone in the household.
Three lengths matched to pot sizes
Each stick is intended for pot sizes in a set band. The small 4.7-inch stick covers 2, 2.5 and 3; the 7.09-inch medium covers 3.5, 4, 5 and 6; the 10.04-inch large covers 6 to 12. A longer stick reaches further down, so the reading comes from root level rather than the top layer.
A replaceable core, made in Japan
The sensing part is a refillable replacement core that lasts approximately 6-9 months. When it stops responding, twist off the cap and swap in a new insert; the outer stick stays in use. The sticks are made in Japan.
What the stick and core are made of, and how to look after them
Each Aquameter has two parts: a slim outer body and a removable core. The refill inserts use a polycarbonate body with a nonwoven fabric refill inside. The fabric draws up moisture from the surrounding soil, and that is what turns the indicator blue when watered and white when dry.
Care is mostly about the core. Plan on a new insert every 6-9 months, and replace it sooner if the color stops changing after you water. Buy cores in the same length as the stick: small, medium and large inserts are not interchangeable. In soils that drain fast and hold little water, the stick may read white soon after watering, so judge those pots with that in mind.

See the sticksWho uses a plant moisture meter, and where
A windowsill of small succulents
Succulents in tiny pots dry out at different rates, so one watering day for the whole shelf rarely fits all of them. A small stick in each pot sized 2 to 3 shows which ones are still damp. The 12-stick bundle covers a whole sill.
Floor plants in big planters
In a pot sized 6 to 12, the surface can look dry while the lower soil is still wet. The 10-inch large sensor pen reaches further down, and the black version blends into dark planters.
A shared home where several people water
When more than one person looks after the plants, a visible signal stops double watering. Anyone can read blue or white without knowing the plant. For a living room of mid-size pots, a 4-pack of medium sticks gives each pot its own indicator.
Greenhouse benches and large collections
Growers with dozens of potted plants in sizes 3.5 to 6 can set one medium stick per pot. The 24-stick bundle is sized for that kind of continuous monitoring across a bench or a plant room.
About the Sustee Aquameter range
The range is a single product idea in several forms: a moisture sensor stick that lives in the pot and reports soil moisture by color. The Aquameter is sold as single sticks, as multi-packs of 2 to 36, and as refill inserts in packs of 2 to 24.
Size is the main split. Small, medium and large sticks map to pot sizes rather than to plant types, so the same medium stick works for a pothos or a fern as long as the pot is sized 3.5 to 6. Color is the second split: green, white and black, chosen to match or disappear against a planter.
The range suits house plants and potted plants indoors, from succulent shelves to floor plants. It does not suit pots outside each stick's band, and the reading is less useful in soils that drain fast and hold little water. If your plants sit in a mix of pot sizes, expect to buy more than one length.
