This is the essential plant tool you never knew you needed. Say goodbye to guesswork when it comes to watering. With just one GrowProbe, you can monitor the moisture levels of your entire indoor plant collection. Your GrowProbe will precisely indicate how moist the soil is from top to bottom, even in larger pots, so you can water confidently without second-guessing. It’s an easy and reliable way to prevent over-watering—more economical than buying a moisture meter for each plant. No need for meters, batteries, or refills. How do you use a GrowProbe? It's simple. Insert the GrowProbe into your pot as far as it will go—at nearly 24 cm in length, it’s perfect for larger pots too. Give it a gentle twist to collect soil samples, then pull it out to check the moisture level right down to the bottom of the pot. How do you know when to water? If all the soil samples in the notches are dry, it’s time to water! For plants that like more moisture, like a Peace Lily's or Calatheas you might want to water when only the bottom one or two notches are damp, and the rest are dry. The GrowProbe takes four soil samples at different depths, allowing you to water according to your plant's specific needs. For plants like aroids or hoyas that prefer drying out between waterings, you can wait until even the deepest soil sample is dry. The soil should fall off the GrowProbe like dust, It’s that easy. Who is the GrowProbe for? This tool is perfect for anyone who’s ever been uncertain about when to water their plants. It’s especially useful for those who tend to overwater or for new plant parents still learning to understand their plants and soil. The longer size makes it ideal for medium to large pots, where it’s tough to reach deep enough to check moisture with your finger. Plus, you can skip lifting pots to guess their weight. I’ve even started using mine as a fertilizer mixing stick. Bonus—it also aerates compacted soil right at the root level, where it’s most beneficial. And no more getting dirt under your nails from digging around in the soil! What are the dimensions of the GrowProbe? The GrowProbe is ideal for all your more established indoor plants in medium to larger pots. The probe itself, excluding the leaf-shaped handle, is 23.5 cm long. Including the handle, the total height is 29.5 cm perfect for getting deep down into your large pots
