The main cause of killing houseplants is overwatering not underwatering. This indicator by Sustee helps to avoid both. To get help with overwatering - just water the plant only when the indicator turns from blue to white. And when you stick it in soil and it does not turn even light blue in around half an hour, that means your plant already needs water.

FAQ
When does it turn from blue to white?
When soil moisture is 20%-25% at the bottom of the pot - that's also an optimal time to water.
Can it be used for plants that need drying out, such as succulents?
Succulents need soil to dry out (about 10% soil moisture) between waterings. So you can wait a few more days before adding water, after the indicator turns white.
What if the indicator doesn’t change color after the first time inserting it into the soil?
Soil is probably quite dry. Try watering from the top of the soil so the stick will have a good contact with the substrate and enough moisture to change the color.
When will I know that the inner core needs changing?
We recommend replacing it as given in the average lifespan table to avoid the situation that the core is already depleted and the indicator doesn’t show an accurate moisture level. It’s ok to take the indicator out of the soil occasionally and check the condition of the core.

It's significantly easier and requires no plant knowledge or constant monitoring. Click & Grow gardens, equipped with grow lights and passive watering systems, use proprietary Plant Pods that provide everything the plants need. Compared to traditional pot-and-soil or complex hydroponic systems, there's minimal maintenance and fewer chances for things to go wrong. Our Plant Pods come pre-seeded with all necessary nutrients, require no water quality or pH checks, and need less frequent cleaning. Simply plug it in, add pods and water, then do occasional plant care for best results. Visit our support page for all tips & tricks.
Yes, but growth success rates are significantly lower compared to using our Plant Pods, which the gardens are specifically designed for. Plus, the watering wicks may not work effectively with all soil types or growing mediums. However, we do offer seedless plant pods, which you can use to grow your own seeds at the higher success rate our Plant Pod technology ensures.
Sprouting and harvest times vary by plant. Most plants sprout within a week and are ready for their first harvest within a few weeks, depending on the variety. Leafy greens grow the fastest while fruiting plants take the longest, and most herbs and flowers fall somewhere in between. For specific timelines, check pod packaging, our support page or app page
Click & Grow gardens are not traditional hydroponics systems, but they can be considered an advanced version of it. Traditional hydroponics replaces soil with growing medium, adds nutrients to the water, and relies on artificial light. We simplify the process by pre-packing nutrients and seeds directly into the growing medium, thus eliminating the need for nutrient mixing, water quality testing, and frequent cleaning required by traditional hydroponic systems.
Nothing. Our gardens are the easiest and most foolproof way to grow plants.
Yes, in fact, most of our customers have pets. Click & Grow gardens actually make growing plants easier for pet owners by reducing the risk of tipped-over pots and messy soil spills. Plus, many pets, like rabbits and other furry friends, love the fresh produce from our gardens. However, it’s important to keep in mind that certain parts of some plants (like tomato stalks) are not safe for people or pets to eat. Visit our support page to learn more.
