Detecting Invisible Plant Health Decline

 The Proven Way To Boost Greenhouse Farmers’ Bottom Line: 
Decreased Inputs Increased Yields

Seeing The Invisible

The proven patented system that detects micro-changes in the healthy-looking ‘green’ of plant leaves – days before any deterioration becomes visible to the naked eye.

The Problem

The Global Challenge

In a world where the population is steadily increasing while arable land per capita diminishes, the task of feeding the global population becomes increasingly formidable.


Innovation has emerged as a critical resource to tackle this challenge head-on. However, growers are faced with a myriad of complexities on their journey to sustainably feed the world.

The Hidden Problem

It’s well known to most farmers that standard protocols use more fertilizer than needed, both to ensure higher yields, and to boost immunity to unexpected hazards like disease, cold or heat stress.

Costly Waste For The Farmer

In the best case, however, this excess leads to costly waste of farmer’s financial resources, with surplus leaching into the ground and pollutes precious soil and water. In the worst case, excess fertilizing causes salinization, actively poisoning crops resulting in lost yield.

Fast, Accurate & Cost-effective 

Our breakthrough system ensures crops always get EXACTLY what they need: Never Less – Never More. Never missing nutrition, but also not over-fertilizing crops.


Our Patented Technology

AI-enhanced Early Plant Health Detection & Response

Our unique, continuous dynamic analysis of RGB reflections employs an AI-enhanced & Machine Learning algorithm detects minor changes in plant-health, and automates nutrient management, ensuring optimal crop growth.

Providing 24/7 plant health monitoring via standard video camera images, a WIFI connection uploads real-time data to the cloud. As soon as crop health begins to fail, Leaf Guardian immediately alerts the farmer and automatically adjusts the fertigation system. Then, just days later, Leaf Guardian issues a second alert, either telling farmers that all is well, or directing them to investigate other factors – still days before irreversible damage to their crops occurs.
