4-in-1 Soil Moisture Meter, 300ft Wireless Soil Tester Sensor, Temperature/Light/Time/Soil Hygrometer Monitor with Digital LCD Display for Indoor Outdoor Plants, Garden, Lawn, Gardening Gifts

Monitor keeps contact w 6 plants in different locations but all within 30ft. I move the individual sensors within their pot each week as "moisture" reading will be different in spots. Moisture is the most useful info provided by this device. The relative light reading is also useful as outdoors shadows move with the sun and with this you can tell if the plant is in the shade (sometimes you want a plant in the shade). The air temp reading is the least accurate as light can influence a readout to be 20-30 higher than reality.Have also cross checked the readout from one sensor to another in same pot. Results same. Confirms consistency.Setup instructions vary. Problem can occur while installing batteries into the sensors and they each come "active" in sequence (not internet). The sequence of button presses on the monitor is not intuitive. Read all instructions carefully. I actually returned my first purchase of the product as I did not understand the instructions...Suggest also consider also getting the HSL GOVE Soil Meter for confirmation of moisture levels around each pot before adding water. The HLS GOVE also offers a relative readout of fertilizer level and Ph.

I bought a Firefly petunia, and it's really cool and I really don't want to kill it. I have whatever the opposite of a green thumb is, I've killed multiple succulents, and I've never actually tried but I bet I could kill a cactus too. It's been over 6 months and this thing is still growing, it's still glowing, and it brings me joy. I appreciate this thing's ability to tell me when my plant is thirsty (something something science something something soil moisture.... it speaks plant and can tell me when the plant is thirsty, and you can't convince me any different) and the deep shame it makes me feel if I don't give my very pretty and very good plant water.

I really like the large separate screen that comes with this. Temperature is accurate. New gauges are easy to add. Light reading is fairly accurate but can skew a bit low if the foliage blocks the gauge from the light source. I like the various light level readings, though. The moisture level is the one thing Im not yet 100% on. Sometimes Im not certain it is correct so I will remove it, wipe it off, then reinsert in basically in the same location, and it will then read lower. Its not a concerning difference so I feel its accurate enough to give a good idea of moisture level.

Seems to do what it says okay, though when I put it in a cup of water it read 60% hydration instead of 100%.... I purchased it to use for sterilizing soil at 180F, but the probe measures ambient air temperature and has a maximum reading of 120F, so not helpful for my situation. Will still be neat to use.

Why did you pick this product vs others?:I love that I don't have to wonder if my plants need water or not! No more dirty fingers or guessing.... I've killed a few plants because i overwatered them. Now my digital readout tells me exactly how much water percentage is. Sun amount and temp. I use the temp to tell the temp of each room they're in now too.... awesome product. With the price of plants going crazy, it's nice to know I won't be killing anymore plants!

wont stay connected to the field sensors. replaced batteries. made sure they are within distance. placed meter outside to make sure no walls or buildings are in way of signals. waste of time and money.

I started growing indoor fruit trees and it can be challenging to determine how wet the soil is. My wife bought me the initial unit with one probe. It worked so well I added the additional ones. Now I can determine the moisture leven by looking at the display.I used all 6 and they synced up with no problem. Only thing I wish is that they came with batteries.

I got two of these to monitor the moisture on two newly planted trees. Easy to pair to the main monitor. Great real time readings with time and temp. It has been wonderful to get to help out our new baby trees to survive a hot summer. Definitely recommend
