A scale built for growing.

Place a potted plant on the scale to monitor soil moisture and gain insights into the water movement through the grow. Tare (zero) points can be set to quantify soil conditions such as "too wet", "too dry" or "just right." 

Growbies scales are also useful for measuring harvests. They can be used to track the fluid level in a vessel. Along with mass, temperature is included in the data stream.

Water spray and dust resistant for indoor and outdoor use. The tripod topology is inherently stable. It works well on varied terrain.

Rechargeable via USB-C. 

Both the device firmware and the gateway software were written by Growbies and released as open source.

Satisfaction guaranteed.

I love my Growbies scale for growing and nurturing my indoor plants. I’ve had a philodendron for over 40 years, so it holds a special sentimental value for me. Last year, I decided to split it and make it 2 plants. I placed one on the Growbies scale and watered the other one the way I always had—by guessing! The photos tell the story. The difference has been amazing, and it has been so much fun watching the plant on the Growbies scale absolutely thrive! Growbies reminds me of the story of the Three Little Bears and their porridge: not too hot, not too cold, but just right. In the world of plants, it’s not too little, not too much—just the right amount of water, exactly when they need it and that's what you can count on with Growbies!
After seeing the results for myself, I’m a believer! 🌿💚
