SusteeMedium Refillable Insert Aqua Meter (Green) with Core Installed + 2 Additional Medium Cores - Plant Moisture Sensor For Potted Plants

I have a indoor arabica coffee tree that would occasionally get brown leaf spots and was slow growing. I had tried everything over a couple years including other moisture probes.Fast forward a month after I got this and the brown spots have all disappeared and the tree is sprouting new leaves everywhere!It’s so easy to walk by the plant and immediately tell (at the exact root zone) weather your plant needs water or not.Highly recommended for picky plants!

I use Sustee sensors in all of my indoor plants. I killed several plants before I started using them. They're not perfect, but they have really helped me get a feel for how often each of my plants need watered. With so many plants it's great to see at a glance which plants need watered too.
