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

I wasn't sure about these when they first arrived. I put one in a succulent pot and gave it to my aunt. After getting great feedback on it I decided to give it a shot on one of my plants. It works like a charm for my snake plant. If you wait until it's completely white the soil will be very dry. It's great for plants that need to dry out between waterings. You need to make sure you don't over insert it into the soil too. It must be between the little arrows to work effectively. I'll be buying more in other sizes!

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. (This is a copy and pasta from my medium size review lol)edit: after 2 months of use, it gives inaccurate reading of when the soil needs water and it's dry. It has 1-2 day(s) delay. $13.50 for 2 months of accurate use is alright I guess. It says that they will need to be replaced about 6-9 months but in my experience, it's 2 months :/

I actually bought small, medium and large for my house plants. So far they have worked really well. Some plants you have trouble telling if the need water or not. With these you just check to see if they’re still blue. When they turn white water your plants. Do wait a little while after watering the plant because sometimes you haven’t watered enough and you’ll know when it is still white or barely blue. I recommend these for your house plants. I may try them in some of my potted plants this summer. Decided to let people know that after awhile these do not work properly. It was way less than 6 months when one turned slimy green inside, another was showing the plant didn’t need water( luckily I figured it out before I lost the plant), others didn’t turn blue(Again I almost lost plants for overwatering). Can’t find the “replacements and i’m not sure I want to spend more money for short of a time!

Works better than any other product I found. Not cheap, since you need one of these in every plant pot. Buy the refillable ones, because the wick inside wears out in about a year and refills are available.

I have two very large ficus trees in my living room. They had started dropping a lot of leaves and after ruling out bugs of any sort, I thought maybe I was under or over watering them. These sticks give me a quick glance at how the moisture levels are, and I can water accordingly. Now my ficus (and all my other household plants I ended up using them in), are flourishing. Only down side is I cannot find refills online, but the product is cheap enough I can just buy new ones when the old wear out.

Works well. So nice to be able just to check for color changes to know whether my plants need water.Easy to use. However, on first use I did have to pour water over the top of the stick. At first, I watered the plants then put the sticks into the plants but neither stick changed color. So I thought about it for a while and decided to try wetting the top of the sticks by pouring water over them. They changed color and after that they worked like a charm.

I cannot speak to the longevity of it, but I'm glad I got the small size. It's perfect for small to medium pots and not too thick. When soaking a plant for watering, it changed color in just a few minutes. Now I know I've been oversoaking. It really serves its function and teaches about the plant water level in a very simple way.

Pretty expensive, but hey, it saves your plants. Very accurate and makes sure you do not overwater which is the leading cause of Dead plants. Very easy to see from across the room with nice dark blue color when watered enough and white when the plant needs watering!!!
