Sustee Water Meter – BLACK (3 sizes)

⭐⭐⭐⭐⭐

No over-watering. no neglect

Do your plants (and yourself). a BIG favour with this clever little device. Sustee takes the stress and guesswork out of the biggest impact you have on whether your plants live or die – water!

No accidental overwatering causing root rot. No neglect causing wilting and death. No sticking fingers in dirt (nowhere close to where the roots are anyway!). One of the most time-consuming. worrying parts of plant ownership is now easy peasy. Plus you can leave your plants in the care of flatmates. family and friends without fear. Only water when Sustee turns white. Simple!

Superb for picky plant buddies sensitive to overwatering. plants prone to root rot. or drama queens that don’t handle drying out. especially for wish-list plants in particular. If you’ve been lucky enough to tick something special off your wish-list or have aplant with sentimental value you’d hate to lose – don’t risk killing it over something this simple to prevent getting wrong.

Set and forget

This clever set-and-forget device hangs out down at root level and tells you if you really need to water. Sure. you do our best to guess based on sticking fingers into the soil. but that doesn’t tell you what’s going on at root level where root rot happens. Plus your Sustee speeds up watering time dramatically. A simple glance at the colour of your Sustee tells you everything you need to know. No need to move or lift anyone or stick fingers anywhere. Couldn’t be easier.

How does Sustee work?

The replaceable core inside measures the amount of water down at the tip (at root level where it’s inserted into the soil). That moisture travels up the core. changing the window at the top to blue when wet. and fading back to white when it’s time to water again. It’s that easy!

One Sustee comes with the housing and one core. Each core lasts 3 to 6 months and you can get . The ’20 questions about Sustee’ video will answer all your FAQ’s and is worth a quick watch before you buy.

What size Sustee do you need?

Sustee come in 3 sizes in 3 colours. white. green or new black. Each size also has matching to order with your Sustee but you won’t need a refill for some time (cores last 6 to 9 months).

SMALL is for all the little guys. The entire length is just 12cms. It sits about 7cm tall above soil level when inserted in your pot. Use SMALL for plants where the root are roughly 4cm to 5cm below the top of the soil. for pots up to 9cm to 10cm wide or smaller. and for plants with shallow roots (even if they’re in bigger pots).

MEDIUM is the go for most standard indoor plants. The whole length is 18cms. It sits from 8cm to 11cm above soil level when inserted. This one’s for plants where the roots are roughly 7cm to 11cm down below the top of the soil – for pot sizes from around 10cm up to 18cm wide. Remember soil and root depth is what counts. so for a wide but shallow pot go for the medium. or upgrade to the large for deeper pots. 

LARGE is for all your bigger potted babes. and great for outdoor container plants under cover too. The entire length is 25cm and when inserted it sits 8cm to 15cm above soil level.  For anything in a pot with a width around 18cm up to 36cms and when the roots are about 11cm to 18cm or deeper below the top of the soil. Also for smaller width but deeper pots (you get the idea by now. but remember it’s the soil and root depth that counts more than the pot width).
