Sustee Aquameter, White, Medium, Set of 2 - Soil Moisture Meter for Potted Plants - Plant Water Sensor (Refillable Style)

At first I thought they didn’t work because they would not turn blue after putting enough water in the pot and maybe even more. I left it alone and noticed the next day, they were all blue. Now i feel they turn blue much faster Than the first time. I love these things. I was watering my plants once a week and after using this, I realized a few of them needed water more often and they are thriving now. I love the convenience of just looking and knowing when it’s water time. No more guessing or sticking my fingers in the soil. I haven’t had to replace the filter yet so idk how that’s going to be like. Hopefully not too expensive or hard to change..

Nice product

Seems to be accurate and definitely easy to use. It took about 30 min for it to read that the soil was wet the first time I used, but is easy to see from a distance and works much better than my finger at gauging moisture.

I love this product. I have ordered other plastic and medal sensors and do not find them reliable. You can also move this sensor form plant to plant if you do not have enough for all of your plants. I occasionally use them outside just for a quick check. They do wear out and have to be replaced, but are well worth the price. They help even the most knowledgeable gardener keep all plants appropriately watered.

I love my indoor plants, but always either over-water them or not enough. I could never get it right, until now!I have only been using the product for about 3 weeks, but so far, it seems to be working perfectly. Blue when its watered, white when it needs to be watered.Will update in a couple of months with more info!

Initially, it took a while for it to turn blue after just watering but after the first time, it turns blue faster. I was a bit sceptical if it really works so when it turned white, I did the finger test in the soil just to make sure. Yes, it works! ٩( ᐖ )۶ I still do the finger test anyways lol. Works for any soil type unlike the other moisture measuring tools. They have 3 different sizes. I got small and medium. In my picture, small is in the front and medium's in the back :3 perfect for bonsais that like dry soil before getting watered.edit: after 2 months of use, it gives inaccurate reading of when the soil needs water. It has 1-2 day(s) delay. $15 for 2 months of accurate use is decent I guess. It says that they will need to be replaced about 6-9 months but in my experience, it's 2 months :/

They are very easy to use, but the two I purchased turned blue OK when water was added, but they stayed blue when water was completely gone.

So far, this has helped me keep track of my alocasia during its time producing so many leaves. With this, I’ve been better with not over watering or under watering. I do like it even though the price is a little too pricey for me personally but it’s been worth the investment so far.
